Problem StatementThe material is misaligned after the
emerges process in the furnace. Before entering the furnace, materials was
aligned properly.
benefit of problem solvingIf the problem is solved, the
productivity of the products will increases and the risk of the failure will
be lower.

No proper guideline Design limitation Lack of Experience
Impact on materials Height difference Design Error
Type of MMCB Thermal expansion and contraction
Part 1(a)MMCB—Metal Mesh Conveyor Belt
The guide pin is merge to the
material. Acting as the legs of the input
material.As there is a metal mesh belt, there is a chain gap, the guide pin can be easily slot in. This is to
prevent the material missaligned.

If the stability of the MMCB is increased. Then the vibration on the MMCB is reduced.
But the stress on the belt and the cost of maintainance is increased.
Tighten the bolt at one end and loosen the bolt at the another end to reduce the vibration on the belt.
The output from the furnace.

Problem statement
???
?
HAND DRILL IS HEAVY.
WHY??CASE 1CASE 2
The Work piece is a fail prototype which the hole is not perpendicular.
Having trouble on operating hand drill??
HAND DRILL IS HARD TO OPERATE(TOO MANY BUTTON & DRILLING NOT ACCURATE).
Loves to DIY. However sometimes…Lead to sadness and disappointment.WHY??
Reason 1Reason 2
Over Drill
The drilling process fail although marking was made on the drill bits and the measurement unit attach on the hand drill is to prevent over drill. However if over force was applied it will still cause over drill.
Reason 2 : The method use for prevent over drill is not effective
Reason 1 : The Drill is not Accurate

Benefits if problem is solved
Problem statementMany woman and “Mr.DIY” face problem on inaccurate drilling and over drill situation . Besides that, woman also face problem on the complexity of the hand drill button and the weight of the hand drill.
The Market Value of the Hand Drill increases and convert the non-customer(Woman & Mr.DIY) to customer.

Drilling not accurate
User problem
Lack of experience
Never try before or lack of practice
Afraid Failure
Failure can cause the project cost increase
Drilling vibration is
too high
No feedback Drilling position not handle properly
Using wrong Drilling tools
User careless
The surface of the material to be drill
is not smooth
The materials selection is
wrong

AnalysisEngineering ContradictionContradiction Matrix
If feedback process is properly done.Then the accuracy of the drilling process is increased.But the loss of time and the device complexity will be increased.

Adding feedback sensor on the hand drill
Inertia Measurement Unit(IMU) is a sensor that are used for balancing while in this hand drill application, it function by providing feedback on the degree of angle of the hand drill
Ultrasonic sensor is the sensor to provide feedback on the distance
