Engineering Contradiction Analysis
1Ease of manufacture
If capacitive coupling is used to connect the support pipe and tap main body, then the structure is simple and cost is low, but the touch sensitivity is low and touch failure may occur
Solution Approach 1:
The patent changes the electrical connection parameter from capacitive coupling to direct conductive connection by introducing a conductive element (metal strip or conductive rubber) between the support pipe and tap main body, thereby improving touch sensitivity while maintaining structural simplicity
Solution Approach 2:
The patent introduces a conductive intermediary element (metal strip or conductive rubber) that mediates the electrical connection between the support pipe and tap main body, enabling direct signal transmission while avoiding the complexity of rigid electronic elements
2Reliability
If a conductive metal element or rigid electronic element is provided for direct electrical conduction, then the touch sensitivity is improved, but the cost and installation difficulty increase
Solution Approach 1:
The patent changes the physical state parameter of the conductive element from rigid (metal strip) to flexible (conductive rubber), enabling direct electrical conduction while simplifying installation and reducing the need for precise positioning and additional fastening components
Solution Approach 2:
The patent uses conductive rubber, a composite material that combines the electrical conductivity of metal with the flexibility and ease of installation of rubber, thereby improving touch sensitivity while avoiding the complexity associated with rigid electronic elements
3Reliability
If a rigid dielectric element is used for electrical conduction, then direct electrical connection is achieved, but the support pipe scrapes and makes noise during rotation
Solution Approach 1:
The patent changes the friction parameter by replacing the rigid dielectric element with a flexible conductive rubber element, which reduces friction during rotation, eliminates scraping and noise, while maintaining direct electrical connection
Solution Approach 2:
The patent uses conductive rubber, a flexible material, to replace rigid electronic elements, allowing the support pipe to rotate smoothly without scraping or noise while maintaining electrical connection through the flexible conductive material
