Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a printed conductive coating is applied to the infrared emitting coating, then electrical conduction is achieved, but adhesion and bonding are insufficient causing poor contact
Solution Approach 1:
The conductive element is separated from the infrared emitting coating, with the retaining mechanism providing structural support for the conductive element while maintaining electrical contact through abutment rather than direct bonding
Solution Approach 2:
The retaining mechanism acts as an intermediary component that supports the conductive element and ensures stable electrical contact with the infrared emitting coating without requiring direct adhesion between the conductive coating and the infrared coating
2Reliability
If a printed conductive coating is used, then power supply is achieved, but the effective heating area is reduced due to coating printing limitations
Solution Approach 1:
The conductive element is segmented from the infrared emitting coating, allowing the infrared coating to cover the entire surface of the emitter without being interrupted by printed electrode patterns
Solution Approach 2:
The conductive element is positioned at specific locations (abutting the infrared emitting coating) to provide electrical contact, while the rest of the infrared emitter surface maintains full coating coverage for optimal heating performance
