- 3. PROTOTYPE
- 5. INTRODUCTION
- 6. Hanging clothes is a daily activity. Becomes a problem when it is taking a long time to complete. The user could not collect all the clothes quickly when heavy rain is approaching.
- 7. PROBLEM STATEMENT The designed of the conventional hanger has required user to perform few actions to hang and collect cloths. As the cloths increases, the required action need to repeat many times which consume lot time to complete the work
- 8. Able to hang clothes easily. Time saving when collecting clothes. Able to collect clothes with single hand. BENEFITS OR IMPACT IF PROBLEM IS SOLVED
- 9. The strength of the hanger must able to support the weight of wet clothes. Manufacturing process has to be same with the existing method. The overall size of the hanger is same with the conventional. The cost of the new product for 5 dozens units must less than RM 100. Types of clothes must be acceptable as in conventional hanger. BOUNDARY CONDITION
- 12. Analyse the interaction between components Construct a Function Model of an Engineering System Concentrate the problem area System Subsystem Supersystem Clothes Hanger Hook Sun Hanger frame Clothes Wind
- 14. CAUSE & EFFECT CHAIN ANALYSIS (CEC)
- 20. TREND OF ENGINEERING SYSTEM EVOLUTION (TESE)
- 24. Parameter involved: Improving parameter: Quantity of substance Worsening parameter: Loss in time IF I INCREASE THE NUMBER OF HANGER, THEN MORE CLOTHES CAN BE HUNG AND DRIED, BUT IT TAKES LONGER TIME TO HANG THE CLOTHES.
- 25. Suggested Inventive Principles: #35 Parameter changes #38 Strong oxidants #18 Mechanical vibration/ oscillation #16 Partial or excessive action CONTRADICTION MATRIX
- 26. Change an object’s physical state (e.g. to a gas, liquid or solid) Change the plastic hanger’s degree of flexibility Though is a great principle solution BUT!!! Boundary Condition restrict change of the material and manufacturing of the plastic hanger. #35 PARAMETER CHANGES
- 28. #9 Prior counter- action #10 Preliminary action #11 Beforehand cushioning #15 Dynamization #16 Partial or excessive action #19 Periodic action #20 Continuity of useful action #34 Discarding and recovering #37 Thermal expansion SEPARATION IN TIME
- 29. If an object (process) id rigid or inflexible, make it movable or adaptive. It is a potential solution. Also suggested from TESE specifically the S-Curve and Trend.
- 30. Proposed Solution Removed the base frame of the hanger Divide the hanger frame into middle part and frame arm with a join (Frame arm movable)
- 31. • Insert spring under the frame • Spring constant, K must be high enough to hold the weight of the frame and the weight of the cloth hung. • But, is must be elastic so that user can compress with light force. Add spring to the frame
Editor's Notes
- #13: Basically function analysis is to analyse the interaction between two or more components. Before we go to any other analysis or problem solving, we have to construct a function model of the engineering system. This can be helping in concentrating the problem area to be solved.
- #15: The following is Cause and effect chain analysis is to identify all the cause and effect of the problem. With all the cause and effect we than construct a CEC chart.
- #16: Here, we can actually determine the root cause of the problem is the inelasticity properties of the hanger used in our daily clothes hanging process. Hence, further concept and idea will be develop based on this root cause
- #18: Hence, by looking at the advantages and disadvantages of both systems, the elasticity properties of the hanging cord can be transferred into the rigid body of the hanger to increase its functionality and suitability.
- #20: The conventional clothes hanger is at the third stage and has reach the maturity stage. It has reach “stable” suitability in terms of usage and also the manufacturing processes. Hanger is able to be mass produced easily with low cost with current manufacturing technology - machinery or plastic molding. However, those hangers that are available in the market currently are only differed by its shape, additional functionality or materials.
- #22: Trends of Engineering Systems Evolution (TESE) are empirically derived directions of Engineering System development that describe the natural transitions of Engineering Systems from one state to another. A number of trends have been described to date and they relate to one another through a hierarchical structure. The trend that relate closely to our stated problem is trend of increasing dynamicity. By increasing the hanger dynamicity, it will able to make the hanger to be more flexible and changeable shape.
- #23: The trend that relate closely to our stated problem is trend of increasing dynamicity. By increasing the hanger dynamicity, it will able to make the hanger to be more flexible and changeable shape.
