Part 1aIndustry Problem

Ensure the semi-processed material is properly aligned at the output without decreasing the productivity.

Problem Statement

Goal

A semi-processed material which is properly aligned before entering the 5 meter long furnace. However, it appeared to be misaligned at the output. It is moved by metal mesh conveyor belt. Since the furnace is hot and enclosed, no one knows what happened inside.

Benefits if problem solved

• Workforce can be saved as no need to realign the semi-processed material manually.

• Lead time can be decreased as no need waste time for realignment.

• Hence, productivity can be increased.

Part 1aIndustry Problem1st SOLUTION

• A new substance is added to S1 to solve the insufficiency

• A holder/handle is added to solve the insufficiency

• The holder can either a new part or weld onto the metal mesh conveyor

• Illustration of solution:

• Engineering Contradiction Tool is used for solving the problem too

• The first contradiction is measurement accuracy (improving parameter) versus productivity (worsening parameter)• The second contradiction is

reliability versus productivity

Part 1aIndustry Problem2nd SOLUTION

Improving Parameter\Worsening Parameter … 39… 27 1, 35, 29, 3828 10, 34, 28, 32…

• Principle 10th suggested preliminary action, means perform and reinforce the required alignment before action.

• Similar with above solution, handle added.• Principle 28th suggested mechanical

substitution, using camera sensor to do the alignment with controlling of tensioning bolts.

• Principle 35th suggested parameter changes. The dimension at the entrance of furnace embedded with sorting function. The size is just fit for the material passes through so that the alignment at output won’t run off.

Conclusion

• TRIZ can be utilized to solve the

alignment problem in this case.

• Among the potential solutions

purposed, the first and last solutions

are more applicable.

• 1. Add a handle/holder

2. Make the entrance and passage just

fit for the material to pass through.

• Problem solved!!
