Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If bio-soluble inorganic fibers are used as support member, then health safety is improved, but reaction with heat-generating member at high temperatures occurs causing melting
Solution Approach 1:
A silica-containing treatment agent is applied as an intermediary layer on the support member surface. This treatment agent acts as a mediator between the bio-soluble inorganic fibers and the heat-generating member, preventing direct contact and reaction while maintaining the health safety benefits of bio-soluble fibers. The treatment agent forms a protective barrier that suppresses high-temperature reactions.
Solution Approach 2:
The support member is constructed as a composite material system combining bio-soluble inorganic fibers with a silica-containing treatment agent. This composite structure integrates the health safety advantages of bio-soluble fibers with the high-temperature stability of silica-based materials, resolving the contradiction between health safety and thermal stability.
2Reliability
If support member surface is coated with silica-containing treatment agent, then reaction suppression is improved, but manufacturing complexity increases
Solution Approach 1:
The silica-containing treatment agent contains silica in a specific concentration range (5-50 mass%) that optimizes both reaction suppression performance and manufacturing feasibility. By controlling the silica content parameter within this range, the patent achieves effective protection while maintaining practical manufacturability through conventional coating processes.
