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
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.
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.

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

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.
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.
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
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.
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.
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.
