Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a recess is created in the heating panel and the heating element is inserted into it, then the heating element can be securely mounted, but the production process becomes long and complex with elevated production costs
Solution Approach 1:
The heating element is integrated directly into the panel structure without requiring a separate recess, merging the mounting function with the panel body itself. This eliminates the need for complex recess creation and insertion processes while maintaining secure mounting through direct contact between the heating element and panel surface.
2Reliability
If fastening means are used to constrain the heating element to the panel, then the heating element remains securely fixed, but heat transmission efficiency is reduced due to heat absorption by the fastening means
Solution Approach 1:
The fastening means are completely removed from the system. Instead of using separate fastening components that absorb heat, the heating element is directly coupled to the panel structure, eliminating the thermal barrier created by intermediate fastening materials and maximizing heat transmission efficiency.
3Reliability
If epoxy resin is used to incorporate the heating element in the panel, then the heating element is securely embedded, but the epoxy resin limits heat transmission and the production process becomes complex requiring molds, heat, and pressure
Solution Approach 1:
The invention replaces the complex epoxy resin embedding process with a simpler, temporary adhesive application. The adhesive serves its purpose of securing the heating element during installation and operation, but can be easily removed or replaced if needed, unlike the permanent and complex epoxy resin process that requires molds, heat, and pressure.
4Strength
If the entire panel must be replaced in case of heating element fault, then structural integrity is maintained, but maintenance becomes complex and time-consuming
Solution Approach 1:
The heating element is designed as a separate, replaceable module that can be independently removed and replaced without affecting the panel structure. This segmentation allows the heating element to be serviced separately while maintaining the integrity of the overall panel assembly, significantly simplifying maintenance operations.
5Reliability
If conventional protection means are used against electrical shock, then some protection is provided, but the protection is relatively ineffective and difficult to produce
Solution Approach 1:
The panel incorporates a composite structure with a conductive shield layer integrated into the panel material itself. This composite design provides effective electrical shock protection and electromagnetic interference shielding through the inherent properties of the composite material, eliminating the need for separate, complex protection components.
