Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple layers or different products are used to achieve varying conductivity levels, then different conductivity levels can be obtained, but the process complexity and number of steps increase
Solution Approach 1:
The patent applies local quality by creating regions with different conductivities within a single coating layer. This is achieved by varying the concentration of conductive particles or the thickness of the coating in different areas of the substrate, allowing each region to have the desired conductivity level without requiring multiple separate coating applications or different coating products.
2Adaptability or versatility
If multiple inks or coatings are applied to achieve different conductivity levels, then variable conductivity can be obtained, but the manufacturing time and number of steps increase
Solution Approach 1:
The patent merges the function of multiple conductive coatings into a single coating composition that can produce variable conductivity levels. By incorporating conductive particles of different sizes, shapes, or materials within the same coating matrix, the system achieves multi-level conductivity control in one application step, eliminating the need for sequential application of multiple specialized coatings.
3Ease of manufacture
If a single uniform coating is applied, then the process is simple, but only one conductivity level can be achieved
Solution Approach 1:
The patent employs parameter changes by modifying the concentration, size distribution, or type of conductive particles within a single coating composition. By controlling these parameters during the coating process, different regions can achieve different conductivity levels while maintaining a unified coating application process, thus preserving simplicity while gaining versatility.
