1 Kuliah 6 : Penyusunan Konsep (Concept Generation)

2 Dira Ernawati,ST.MT - P32 Konsep Produk ? Sebuah gambaran / perkiraan mengenai teknologi, prinsip kerja, dan bentuk produk. Sebuah gambaran / perkiraan mengenai teknologi, prinsip kerja, dan bentuk produk. Gambaran singkat bagaimana produk memuaskan kebutuhan pelanggan. Gambaran singkat bagaimana produk memuaskan kebutuhan pelanggan. Biasanya diekspresikan sebagai sebuah sketsa atau model 3 dimensi secara garis besar dan disertai uraian gambar Biasanya diekspresikan sebagai sebuah sketsa atau model 3 dimensi secara garis besar dan disertai uraian gambar

3 Dira Ernawati,ST.MT - P33 Aktivitas Penyusunan Konsep Proses penyusunan konsep dimulai dengan serangkaian kebutuhan pelanggan dan spesifikasi target, dan diakhiri dengan terciptanya beberapa konsep produk sebagai sebuah pilihan akhir Proses penyusunan konsep dimulai dengan serangkaian kebutuhan pelanggan dan spesifikasi target, dan diakhiri dengan terciptanya beberapa konsep produk sebagai sebuah pilihan akhir Penyusunan konsep yang baik memberi keyakinan pada tim bahwa seluruh kemungkinan telah digali. Penyusunan konsep yang baik memberi keyakinan pada tim bahwa seluruh kemungkinan telah digali.

4 Dira Ernawati,ST.MT - P34 Kesalahan-kesalahan dalam Penyusunan Konsep Hanya mempertimbangkan 1 atau 2 alternatif Hanya mempertimbangkan 1 atau 2 alternatif Kegagalan mempertimbangkan kegunaan konsep yang dipakai oleh perusahaan lain. Kegagalan mempertimbangkan kegunaan konsep yang dipakai oleh perusahaan lain. Hanya melibatkan 1 atau 2 orang dalam proses, menyebabkan kurangnya kepercayaan dan tanggung jawab dari anggota tim lainnya Hanya melibatkan 1 atau 2 orang dalam proses, menyebabkan kurangnya kepercayaan dan tanggung jawab dari anggota tim lainnya Integrasi yang tidak efektif untuk menemukan solusi parsial yang menjanjikan Integrasi yang tidak efektif untuk menemukan solusi parsial yang menjanjikan Kesalahan mempertimbangkan seluruh kategori penyelesaian Kesalahan mempertimbangkan seluruh kategori penyelesaian

5 Dira Ernawati,ST.MT - P35 Concept Generation Most Important Aspect of Design Most Difficult Aspect of Design Brainstorming Include everyone (Marketing, Purchasers, Manufacturing, etc.) Need MANY possible ideas! (The more, the better!)

9 Dira Ernawati,ST.MT - P39 Problem Decomposition Functional Decomposition (for technical product) Functional Decomposition (for technical product) Decomposition by sequence of user action: is often useful for products with very simple technical functions involving a lot of user interaction Decomposition by sequence of user action: is often useful for products with very simple technical functions involving a lot of user interaction Decomposition by key customer needs: is often useful for product in which form, and not working principles or technology, is the primary problem Decomposition by key customer needs: is often useful for product in which form, and not working principles or technology, is the primary problem

10 Dira Ernawati,ST.MT - P310 Functional Decomposition Function: WHAT the product must do Function: WHAT the product must do Form (Shape, or Structure): HOW the product will do it Form (Shape, or Structure): HOW the product will do it “Form follows function” “Form follows function”

11 Dira Ernawati,ST.MT - P311 Functional Decomposition System Flow Diagram System Flow Diagram Energy, Material, Information (Signal) System Flow Diagram Energy, Material, Information (Signal) System Flow Diagram system inputs outputs system energy inputs material inputs information inputs energy outputs material outputs information outputs

12 Dira Ernawati,ST.MT - P312 Concept Generation Exercise: Vegetable Peelers

13 Dira Ernawati,ST.MT - P313 Peeler: System Flow Diagram Peel Vegetable Whole vegetable Peeled vegetable InputOutput

14 Dira Ernawati,ST.MT - P314 Peeler: Functional Decomposition Manipulate Vegetable Separate Skin Hand Power Apply Hand Power Discard Skin Whole Vegetable Peeled Vegetable

15 Dira Ernawati,ST.MT - P315 Concept Generation Example: Power Nailer

16 Dira Ernawati,ST.MT - P316 Problem Decomposition: Function Diagram Store nails Store or accept external energy Isolate nail Convert energy to translational energy Apply translational energy to nail Sense trip Trigger tool Energy Nails "Trip" of tool Driven nail Hand-held nailer Energy (?) Signal (?) Material (nails) Energy (?) Signal (tool "trip") INPUTOUTPUT Material (driven nail)

17 Dira Ernawati,ST.MT - P317 External Search: Hints for Finding Related Solutions Lead Users Lead Users benefit from improvement benefit from improvement innovation source innovation source Benchmarking Benchmarking competitive products competitive products Experts Experts technical experts technical experts experienced customers experienced customers Patents Patents search related inventions search related inventions Literature Literature technical journals technical journals trade literature trade literature

18 Dira Ernawati,ST.MT - P318 Internal Search: Hints for Generating Many Concepts Suspend judgment Suspend judgment Generate a lot of ideas Generate a lot of ideas Infeasible ideas are welcome Infeasible ideas are welcome Use graphical and physical media Use graphical and physical media Make analogies Make analogies Wish and wonder Wish and wonder Solve the conflict Solve the conflict Use related stimuli Use related stimuli Use unrelated stimuli Use unrelated stimuli Set quantitative goals Set quantitative goals Use the gallery method Use the gallery method Trade ideas in a group Trade ideas in a group

19 Dira Ernawati,ST.MT - P319 Explore Systematically Concept Classification Tree Concept Classification Tree Concept Combination Table Concept Combination Table Managing the Exploration Process Managing the Exploration Process

20 Dira Ernawati,ST.MT - P320 Concept Classification Tree Goal: generate as many concepts as possible Goal: generate as many concepts as possible An elementary approach to developing a functional description of a product An elementary approach to developing a functional description of a product Decompose prime function hierarchically into sub functions Decompose prime function hierarchically into sub functions For each function, develop as many alternative functions as possible For each function, develop as many alternative functions as possible For each subfunction, develop as many means of accomplishing the function as possible For each subfunction, develop as many means of accomplishing the function as possible Fast and simple, but interconnecting links between sub functions not considered Fast and simple, but interconnecting links between sub functions not considered

21 Dira Ernawati,ST.MT - P321 Concept Combination Table Method: Select one concept for each function and combine those selected into a single design Method: Select one concept for each function and combine those selected into a single design Cautions Cautions May generate too many ideas May generate too many ideas Erroneously assumes that each function is independent and each concept satisfies only one function Erroneously assumes that each function is independent and each concept satisfies only one function results may not make sense results may not make sense

22 Dira Ernawati,ST.MT - P322 Generating Concepts From Functions Concept Combination Table

23 Dira Ernawati,ST.MT - P323 Generating Concepts From Functions Concept Combination Table

24 Dira Ernawati,ST.MT - P324 Generating Concepts From Functions Sebuah solenoida menekan sebuah pegas dan kemudian melepaskannya dengan berulangkali untuk menjalankan paku dengan hantaman yang berulang

25 Dira Ernawati,ST.MT - P325 Generating Concepts From Functions Concept Combination Table

26 Dira Ernawati,ST.MT - P326 Generating Concepts From Functions Motor akan memutar pegas, menghasilkan akumulasi energi potensial yang kemudian diantarkan pada paku dengan sekali pukulan

27 Dira Ernawati,ST.MT - P327 Generating Concepts From Functions Concept Combination Table

28 Dira Ernawati,ST.MT - P328 Generating Concepts From Functions Motor akan berputar dan melepaskan pegas, menyimpan dan mengantarkan energi melalui beberapa pukulan.

29 Dira Ernawati,ST.MT - P329 Generating Concepts From Functions Concept Combination Table

30 Dira Ernawati,ST.MT - P330 Generating Concepts From Functions Motor linier akan mengakselerasikan palu besar, mengakumulasikan energi kinestik yang dihantarkan pada paku melalui pukulan tunggal
