Of the 135 occupants, there were 50 injuries and nine deaths, including four of Boeing’s engineers. Keywords: TRIZ, system models, problem formulation 1. While the system operator has existed for some time within TRIZ literature (Reference 1), it is not clear whether the concept was first derived by TRIZ researchers or not. An exceptional solution may approach the IFR in delivering the desired outcome at minimal cost. Consider the narrow zone where force, material and information (interchange) occurs as an interface among the EV (considered a system of interest) and the other corresponding components with which it interacts. Special polymer panels are mounted flush with the exterior skin to register dynamic air pressure for SV21. Detection, clearance and verification done automatically by the same SV. This can be seen in SV19 and SV22, where both approach a high IFR when compared to SV26. ), An almost identical accident took place only seven months prior on February 6, 1996 when another Boeing 757-225 (registration TC-GEN), operated as a charter flight by Birgenair, crashed into the ocean at night soon after take-off.4. In TRIZ the suggestion is to consider using freely available resources first and then try to achieve solutions where the desired result is achieved.

Paradigm change [FS + PC]: The fifth level functional stream requires different thinking. In SV13 it is intensified by using a high pressure pulse for clearance of internal or taped over obstructions. Économisez sur des grandes marques avec votre CARTE U. L'ESPACE JEUX. This is also an example of the FS + 3 (functional stream). System / Sub-system / Super-system Jack Hipple Last month we discussed how using TRIZ in management and organizational problem solving can be a bit more complicated because the definition of the "ideal" result can become complicated by the views of different people and their motives and incentives. This relationship is linear throughout all conceivable flight parameters. Fig. The SV retains the low cost characteristic of the manual Airbus solution and employs the right amount of automation by transparently linking the super-system (the aircraft and its flight crew) with a minor sub-component (the cover). This is a key resource, widely available at a non-prohibitive cost. A new method of detecting a ping or pulse some distance downstream needs to be developed. Evolutionary [FS + 4]: The fourth level functional stream is derived by focusing on the EV and by devising an evolutionary replacement for its constituents. More... 3. Efficient innovation: results from the maximal use of resources that are often freely and readily available and by the conversion of constraints into opportunities. Airline disasters have resulted from confusion in the cockpit caused by poor ground communications, bad weather, pilot fatigue, failure of ground navigation aids and more. This SV relies on monitoring decay of a low-pressure air pulse within the circuit.

SV10: Use ram air with easy peel-off paint around port opening. Area of moving object. The concept of innovation in the large is different. Pitot-static systems were around in the 1930s (if not earlier). In the present case, the super-system consists of the steel, the enamel, the thermal treatment and the application process, while the micro-system is made of the chemical elements Fe, C and O, the iron oxides, the inter-metallic layer, the bonding oxides (referred to as “catalysts” on Figure 5) and the roughness of the steel. The SSA presents the EV as a composite of the assumptions with the prior knowledge about the problem space. A technique like 9 windows can be better understood with examples and the one below from triz journal explores mobile phone as a system and ideates to find the future system, sub-system and super-system. Minimal coordination (ensuring desired relationships and interferences). SV23: Use ionized air pulsing to measure airflow. The outcome of any innovation activity is almost entirely contingent upon the following five factors: The accident descriptions given provide sufficient information to define the problem, form assumptions and decide on directions for investigation. The internal tubing of the pitot-static circuit and location of the transducers has to be re-routed inside the front of the aircraft. The four SVs address the issue of tape removal of the static port, which is a somewhat unlikely occurrence. Bons de réduction. Certainly a form of the 9-windows – in actual fact, as we will see in the third article, a more comprehensive form – was included in very early NLP literature (Reference 2). For SV14 it suggests a sliding arrangement, while SV15 is based on a rotating/pivoting arrangement. � �H3�����g�(���7�s�5��,��w湧����=�vg�`/m �i[��~�ۀ�68s��Q#96��V��t�q;Rb���,����k�� i�e"e�"8;�s�Qy���j�K��v�KO%q1bc���Dي�l)��������*I,�^;d�z�Q�$g�`wq��H�H��9��@k�+h�M�#�J=�3{ُ8CN��^h^���F'��ެ��O!�ED�b)h����p�Ө>K�:GR1Z�Z� �՜�}�~QPSN�6���'��G��ez�i����r�H���A0�` �:j� ARIZ is the central analytical tool of TRIZ. can enter at this stage when evaluating the entire SV set. The objective is to directly obtain air pressure and dynamic air pressure data from the ambient airflow. 39 Parameters of TRIZ. While the problem was originally addressed through root cause … Using simple neural networks, self-calibration of data would be possible. Space Resources, Time Resources, System resources, Function Resources, Information, Substances, Energy and Field Resources … In TRIZ, the system evolves towards ideality when the Contradiction Matrix (worsening and improving) is overcome. This caused the plane to slow down (almost to the point of entering a stall) when the wings stopped generating lift. The goal is to generate more than one SV (minimum of four SVs in a set). The anomaly, however, occurred in the flow and processing of information. Fermer . Changing what our system does can be a powerful way to meet user needs and desired experiences. The SSA is based on knowledge abstractions that encapsulate what is known about the system of interest along specific paths of inquiry. ��\�+'C�d�CUWYN��^��M�����>�E��,���t�C�9G��?ӝf�K��*���}�D��A�Y��Ͳ�Πt��c���?Wp)���?���\e�>A�iY�cl8�6�+�N�-�6����k���y}}���h)ɲ�b���3�ͩ9�ajEZf�&y�}s��q괩��w�d�v���Wg�u��tҙ�ӏ�n��*����V��W��A˜Q|swz8f �_� q�LB When initiated at any level within the system of interest it promotes the rapid generation of other innovative solutions within the system. More... 5. SV25: Use ground mapping radar with digital terrain matching. Referring to the Contradiction Matrix, the model of solution is determined based on Specific Inventive Principles. No external act of nature forced a deviation from the normal flight path. To this problem they applied TRIZ; functional analysis, trends and evolutionary potential analysis, super-system perspective of the machine, and evolutionary potential analysis of the business model. The new approach combines TRIZ thinking with systems engineering principles. The ideal final result (IFR) is to not have a problem in the first place. As TRIZ recommends, consider all resources when coming up with innovative ideas for the task in question. The left engine took on water and flamed out. I can’t think of anything finer. Length of moving object. The benefit of SV22 lies in the fact that the skin panels are made to perform two entirely separate and unrelated tasks, simultaneously, without functional interference. The super system augmented (SSA) approach is based on hybrid reasoning. These SVs are the active version of SV1 for the detection of tape using the principle of reflected acoustic or light beam. Also, in developing an enhanced vocabulary of innovation terms an individual needs granularity to bring the various components and stages of the innovation process into sharper focus. The author begins building innovation momentum with the air safety issue of adhesive tape removal. 0000001217 00000 n Soon after take-off the air data computer started feeding erroneous data to the flight computer and to the two sets of instruments for the captain and first officer. These issues are not considered earlier. The System Operator is one of the main TRIZ instruments and, of course, one of the best instruments for systematization of thinking. More than three million patents have been used to discover these patterns in order to solve future problems based on a previous literature. The cover can be locked in open and closed positions. Unexpected outcomes that emerge from the exercise as a result of serendipity, What assumptions are made at the inception, What directions for investigation are adopted, What knowledge base is initially available, What additional resources can be used, in due course, to bridge the knowledge-gap. super system enables to increase flow more than 5S can provide. The choice of the EVs determines the immediate, the intermediate and long-term expectations from the exercise. Products and techniques pass through a process of birth, growth, ma-turity, death and quit the stage like biological evolution process. While the original tape removal problem was solved by the airline industry through root cause analysis, recurrences (in March 2006, March 2009 and July 2009) indicate a need for further work in the general airspeed sensor area. On March 5, 2009 it was reported that the likely cause of the crash of Turkish Airlines Boeing 737-800 at Schiphol, Amsterdam was a faulty altimeter. Triz est la solution par excellence pour jeter de nouveaux ponts entre les disciplines." H��T���0��>�!S���}LԦ�$��S��z���*������� Depending on the speed of the aircraft, the time for a pulse of ionized air will vary and can be measured. SV6: Detect presence of covering tape by air pressure release sensor. ̕l1��E# �y����>��w#����AH�#5�sP�Q����gϳ S'amuser n'a jamais été aussi bon pour votre pouvoir d'achat ! 9 Windows – Example. The super system augmented (SSA) approach is based on hybrid reasoning. This is an important concept which needs elaboration. SV21: Use special polymer external panels to register dynamic air pressure. The transmission of information within the pitot-static circuit may be changed by replacing material flow of air pressure with the transmission from the originating source of electronic signals or electro-optical data. Independent verification was sought from the Lima air traffic control radar, which acknowledged the plane’s position and confirmed its height at 8000 feet (ironically a value received from the aircraft’s erroneous transponder). Keywords: TRIZ, system models, problem formulation 1. If you like the TRIZ Journal, please help us by donating towards domain space, admin and technical support. endstream endobj 25 0 obj<>stream This SV is also based on EV3; however, it employs an entirely different approach. EV3:Incomplete situational awareness (an information management issue). There remains the possibility that the ground crew may have a number of spare covers, which they could use for a work-around as a pit crew to minimize on ground turn-around time. The following is a description of the solution vector (SV) process listed in Table 1. In English the name is typically rendered as "the theory of inventive problem solving", and occasionally goes by the English acronym TIPS. The disorientation of the flight crew in the pitch black of night led to the declaration of an emergency; they elected to return to Lima. 8 Lois d'évolution. Ceci se produit lorsque le système ne peut plus évoluer par lui-même. EV1: Susceptibility to blockage through ingestion or icing(a maintenance and design issue). endstream endobj 29 0 obj<>stream The advantage of this SV (from the TRIZ viewpoint) is the existing resources are used to perform additional functions. Introduction. Produits et services U. Produits et services U. Toutes Nos Marques U. All 228 died. The major change is a modified form of transducers that are relocated to the exterior of the aircraft. The pitot-static system is an established and reliable method of obtaining speed- and height-related information.7 The method is simple. The focus is on the following information-related sub-systems within the aircraft (Figure 6), beginning by forming the closed boundary of the system for an aircraft in normal flight. 9 juin 2014 - les systèmes ont tendance à migrer vers le super-système. An earlier version of this paper was published on The TRIZ Home Page in Japan. Reassured by the independent verification, the flight crew started the descent in darkness. 2.1. If the original cover were left on at night, the original problem returns. Profitez de tous les bons plans et offres des Magasins Hyper U, Super U, U express. The aerofoil converts the energy of the airstream into an opening torque. There is little purpose in expending valuable resources for developing concepts that will be bypassed or made redundant by others. In TRIZ, a system is considered as a "system of systems" i.e. Each of the four functional streams represent a snapshot of the EV, differing only in the extent to which the sub-components of the EV can be modified, adapted or replaced (Figure 7). However, the case study he shows consistently here is clear. Loi précédente. In an invention, we typically see some change in the subsystem, system or super-system. Within each path or super stream are mechanisms to drill down into each assumption in detail. A physical contradiction is resolved on the change of condition, as per TRIZ thinking (TRIZ tool: physical contradiction, the cover must be present on ground and must materially disappear once airborne). SV1: Directed light source located within static port. Read more: Lesson 2: Whose "9-BOX" is it? The chartered aircraft had been sitting unattended on the tarmac for several days prior to the flight. xref TRIZ is "a problem-solving, analysis and forecasting tool derived from the study of patterns of invention in the global patent literature". The emitter and receiver are located within a fairing inside the static ports (TRIZ standard solutions 1.1.2, 1.1.4, 3.1.1). The metal skin panels are fitted with strain gauges to convert deflection under air pressure into a pressure reading for SV22.

SV24 suggests using an array of emitters and sensors to obtain three-dimensional flow patterns about the aircraft. 0000000849 00000 n To this problem they applied TRIZ; functional analysis, trends and evolutionary potential analysis, super-system perspective of the machine, and evolutionary potential analysis of the business model. The outstanding advantages of this include: This set of SVs emerges from the problem space with a view to automate the placement and removal of covers on the static ports using TRIZ philosophy first use available resources (SV14 and SV15) to rely on airflow to actuate the covers. Économisez sur des grandes marques avec votre CARTE U. L'ESPACE JEUX. 3.2. The force and information flows within the EV. By imposing the requirement for functional streams each path is resolved further into four paths for detailed analysis. EV4:The inefficient transfer of vital information (an ergonomics issue). How to combine the diametrically opposed requirements of free association of ideas with algorithmic structuring is a debate that will continue for some time. A system For example, what if there is a change to the form of the material? Fermer . Space Resources, Time Resources, System resources, Function Resources, Information, Substances, Energy and Field … Note that the SSA provides a planning and structural layer to manage the innovation activity. <<25dad9a8ca079a4691b3fb4408080152>]>> It will be noticed that the super-system includes the tool and the object of the … The typical user is accustomed to precise, algorithmic approaches through years of formal educational training. The stowage space proposed within the front landing gear door can be wired to indicate that a cover has been properly secured and is no longer on the ports. If safety problems continue, the team can begin to implement future solutions within the subsystem, system, and super-system to change or influence how the past, present, and future processes are utilized. 0000003480 00000 n The aircraft cart wheeled and turned upside down at 1:16 a.m. Any initial survivors had perished by day break. Altitudes displayed were widely different and seemingly contradictory alarms sounded randomly, often simultaneously. But progress stops for no-one. Lutz Schonfeld, Wikimedia Commons. Functional streams encourage the generation of multiple solutions, which may be in varying degrees of completeness at any given point in time. SV9: Use ram air (dynamic air pressure to increase engine power) with pebbled surface around port opening. More... 5.

Thus for the system, super-system and subsystem we take into super-system, the system and subs ystem in order to ensure that the derived solution does not create any problem for the super-system or sub-s ystems. SUPERSYSTEM II est un instrument d'éclairage multifonctions qui remplit des exigences variées dans la vente et la présentation, dans les musées et galeries tout comme dans l'hôtellerie et la gastronomie, dans les salles de conférences et le domaine privé. In 2008, the Sydney Morning Herald reported that between January and March 2006, five Qantas A330 Airbus flights had to abort take-off due to wasp-related blockages of the pitot-static system.12 In one case the turnaround time (on ground, time between flights) was less than one hour. Following Altshuller's … Super-system. A limitation of this SV is that it will not deploy at low speeds as the aircraft is taxiing. EV5:The inefficient processing of time-critical information (a training issue for the flight crew) (a systems design issue for the digital flight controllers). SV16: Built-in retractable metal skin panel over port. mZ���KR��Sb( There is no need to modify the pitot tube or static port geometry at the exterior or interface level. (aka Higher-level system) Courtesy of: Victor Fey. It stands to reason that SV25 and SV26 should be given the highest priority, unless there are valid reasons: technological, policy or other, for delay. 0000000016 00000 n The instruments gave conflicting readings which were disregarded. They also pointed out the … The aircraft stalled, dropped and broke up into three pieces approximately one kilometer from the runway. Murray T C Douglas, Whenuapai Airshow 2009, Auckland, New Zealand. In this case, the momentum should be reversed from this point and redirected toward the middle tier. research utilizes the substance-field analysis and system modeling in TRIZ, to seek for improvement and enhancement of the methods. System minimum modification principle: as much as possible existing resources of These laws are therefore a projection into the future of the system. What is more probable is the partial obstruction of the circuit due to foreign object ingestion, wasp activity, etc. TRIZ and Services Innovation 2.1. Here, the interest is focused on a dynamic study of the EV, its sub-components and internal workings. The super stream augmented approach (SSA) is proposed as a planning and structuring layer to enhance the application of Theory of Inventive Problem Solving (TRIZ) tools for sustained innovation. Airbus airliners come equipped with dedicated port covers. Because our system is part of the super-system it performs select functions within the job. 0000000656 00000 n 0000006000 00000 n A simple, spring-loaded mechanism keeps the ports covered until the force of the airflow is sufficient to move the covers. From a TRIZ viewpoint, this is a superior SV since the problems of tubing blockage are also eliminated with the tubing (TRIZ hint: functional trimming). System features: Size, shape, colour, transparency, weight, roughness, density, porosity, and so on. Fig. super-system, the system and subs ystem in order to ensure that the derived solution does not create any problem for the super-system or sub-s ystems. The SSA approach inter-weaves concepts taken from TRIZ and Systems Engineering. Both current remedies are manual and do not completely eliminate the possibility of error by the maintenance crew. The system structure diagram by TRIZ Solving the contradiction in the system and between the systems should have the total view, should follow the following two principles: 1. Entry vector (EV): the knowledge encapsulation of an assumption regarding the problem into a distinct path leading into the problem solving space. Additionally, the visibility of multiple SVs encourages aspects of serendipity through further ideation and merging. An individual can select the EVs to establish the program’s course. A technique like 9 windows can be better understood with examples and the one below from triz journal explores mobile phone as a system and ideates to find the future system, sub-system and super-system. 8�.�~_} ^,H�R�@y�T�(t����-g��њuļ`daT^&iI�K����v�ƻ�-݌��lH�YTMn�>[߇���Z�Y� Sub-system and component resources: Use raw (as found), combine together, or modify. �c�HpvdMA8���!`Tqy�6K�#�G�kJ�i�X&��i�gq����� g�&|K�j�W\k�bY2x2�Q�:���N?�\f��t��,F�pJW�ޕ� system, the subsystem, and the super-system is shown in Fig.1. Une fois cette intégration faite, le système continue son évolution en tant que sous-système. Since he developed his method (Super-Stream Augmented Approach) for himself through his career as an engineer for over 30 years, some methodological parts of this paper are not familiar even to TRIZ people.

For this reason SSA can be used alternately as an innovation add-on to systems engineering; or as a structuring and planning add-on to innovation tools such as TRIZ. As long as the pitot and static ports are free of obstructions, the system works. When we have a system to analyse, we use 9 boxes to set the system context, define its environment (super-system) and all the details (subsystems). Nine windows is a tool often used in the theory of inventive problem solving (TRIZ). Systematic design and engineering is another essential area best exemplified by the work of German systems engineering experts Gerhard Pahl and Wolfgang Beitz where systematic approaches were used to achieve efficiencies in the field of engineering design.9, The Theory of Inventive Problem Solving has an extensive suite of idea generation tools which are deployed to suit any task.1 This flexibility transfers the responsibility for planning and structuring and its successful execution onto the user. SV13: Use air pressure pulse within port to clear obstruction. For instance, it can be considered that a rolling stock sound absorber is part of the broader pantograph sound … This SV applies TRIZ principles to SV20 to reduce extraneous components by trimming and by merging desired properties within structural components.
