Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If thermally conductive filaments are densely arranged in the support to uniformly heat the gas adsorbent, then heating uniformity is improved, but device complexity and difficulty of electrical conduction introduction worsen
Solution Approach 1:
The patent extracts the heating function from separate thermally conductive filaments and integrates it directly into the honeycomb structure material itself. The honeycomb structure is made of PTC material that generates heat when voltage is applied, eliminating the need for separate heating filaments and their complex electrical connection systems while achieving uniform heating throughout the gas adsorbent.
Solution Approach 2:
The patent merges the structural support function and the heating function into a single integrated component. The honeycomb structure serves both as the mechanical support for the gas adsorbent and as the heating element through its PTC material properties, simplifying the overall device architecture while maintaining effective uniform heating.
2Temperature
If thermally conductive filaments are used to heat the gas adsorbent, then heating capability is improved, but ease of operation worsens due to difficulty in introducing electrical conduction
Solution Approach 1:
The patent eliminates the complex electrical conduction introduction problem by removing the separate thermally conductive filaments. Instead, the honeycomb structure itself is made of PTC material that can be directly connected to power sources through simple electrode layers, dramatically simplifying electrical connection while maintaining effective heating capability.
Solution Approach 2:
The PTC material in the honeycomb structure serves its own heating function without requiring separate heating elements. When voltage is applied through the electrode layers, the PTC material automatically generates heat through its inherent electrical resistance, eliminating the need for complex external heating systems and their associated electrical conduction challenges.
