The process cannot be changed.

The semi-material used is made of metal.

The shape of the semi-material is in bar form.

The semi- processing material is not heavy.

Material emerges at the output in an aligned manner.

Productivity is improved due to the cycle time is reduced.

Eliminate the operator inspection time of misalignment problem.

Material emerges at the output is misaligned.

• Misalignment is caused by the inappropriate speed of theconveyor. Therefore, the appropriate speed needs to beapplied in order to solve the misalignment problem.

tension)

• If the appropriate speed of the conveyor is able to cater for

the materials alignment, then the misalignment will be

avoided, but low flexibility when speed needs to be

changed to adopt the materials movement.

• Design the conveyor belt in two parts, center belt

and side belt.

In this case, refer to class 2 and 3 of the 76 Standard Inventive Solutions.

This problem can be solved with 6 primary solutions. Solution (e) : Add another substance (S3) to either S1 or

S2 is chosen.

Besides using Engineering Contradiction, substance field model also can be applied in solving misalignment problem.

We found that this Su-Field is an ineffective Su-field which is shown as Figure below.

S3

• S3 is another new substance:

• i.e. add the solid jig (S3) and allocate the semi-processmaterials into the solid jig (S3) in order to guide the semi-process materials to transport effectively as shown in Figurebelow.
