Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical wirings are attached to transparent conductive coating for secure connection with low resistance, then electrical connection reliability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent introduces an intermediate conductive layer between the transparent conductive coating and the electrical wiring. This intermediate layer serves as a mediator that simplifies the attachment process while maintaining low resistance connection, thereby improving reliability without significantly increasing device complexity
Solution Approach 2:
The conductive intermediate layer is deposited on the transparent conductive coating before the electrical wiring is attached. This preliminary action prepares the surface for easier wiring attachment and ensures optimal electrical contact, reducing manufacturing difficulty
2Adaptability or versatility
If substrates are coated with transparent conductive coating and coupled to electrical power source, then radiation transmission control function is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent segments the conductive system into multiple layers: transparent conductive coating on substrate, intermediate conductive layer, and electrical wiring. This segmentation allows each layer to be optimized independently and facilitates easier manufacturing while maintaining the radiation transmission control function
Solution Approach 2:
The intermediate conductive layer serves multiple functions: it provides electrical connection, simplifies wiring attachment, and maintains compatibility with standard glazing processes. This multi-functionality improves ease of manufacture without compromising the radiation transmission control capability
3Manufacturing precision
If numerous electrical wirings are attached for large-sized systems and independently controllable segments, then control precision is improved, but productivity deteriorates
Solution Approach 1:
The patent transitions from attaching wirings to the surface of the transparent conductive coating to embedding the intermediate conductive layer within the substrate structure. This dimensional change allows for more efficient wiring integration and improves productivity while maintaining control precision for large-sized systems and independently controllable segments
