Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If thermal stress is applied to the adhesive layer to break the connection, then the adhesive bond is destroyed, but harmful fumes are generated and health risks arise
Solution Approach 1:
The patent replaces the thermal field (electromagnetic heating) with a mechanical field (electrodynamic force from alternating electromagnetic field) to achieve adhesive layer destruction. The alternating electromagnetic field directly generates mechanical stress in the conductive first component through electromagnetic induction, eliminating the need for thermal softening and avoiding harmful fume generation from adhesive decomposition.
Solution Approach 2:
The patent changes the physical parameter used for adhesive destruction from temperature (thermal stress) to electromagnetic field intensity (mechanical stress). By using an alternating electromagnetic field with specific frequency and amplitude, direct mechanical stress is generated in the conductive component, causing relative movement and mechanical destruction of the adhesive layer without thermal effects.
2Strength
If thermal destruction of the adhesive layer is used to break the connection, then the adhesive bond is destroyed, but adhesive remnants remain on components impairing reuse
Solution Approach 1:
The patent uses electromagnetic induction to generate direct mechanical stress in the conductive first component, causing relative movement between components that mechanically destroys the adhesive layer. This mechanical destruction method cleanly separates the adhesive without leaving thermally degraded remnants on the components, preserving component reuseability.
3Object-affected harmful factors
If an enclosed cabin with fume extraction is used to handle thermal adhesive destruction, then health risks are mitigated, but device complexity and process overhead increase
Solution Approach 1:
By replacing thermal field with electromagnetic field that directly generates mechanical stress, the patent eliminates adhesive thermal decomposition and fume generation entirely. This removes the need for enclosed cabins and fume extraction systems, significantly simplifying the device while maintaining health safety.
4Strength
If only electromagnetic heating is applied to the conductive component, then thermal expansion gradient and mechanical stresses are generated to mechanically destroy the adhesive layer, but the process requires precise control to avoid thermal destruction
Solution Approach 1:
The patent uses alternating electromagnetic field that directly generates mechanical stress through electromagnetic induction in the conductive component. This mechanical stress causes relative movement and mechanical destruction of the adhesive layer without relying on thermal effects, eliminating the need for precise temperature control and avoiding accidental thermal destruction of the adhesive.
