Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If switches and indicator lamps are mounted on a circuit board with wiring layout, then various operations can be performed, but the space utilization is reduced and operability is compromised
Solution Approach 1:
The patent extracts the metallic sheet component with integrated touch switches from the traditional circuit board mounting approach. By providing a separate metallic sheet structure that can be positioned independently, the design eliminates the need for extensive wiring layout on the circuit board, thereby improving space utilization while maintaining full operational functionality.
Solution Approach 2:
The patent combines multiple functions into the metallic sheet structure: the sheet itself serves as both the structural component and the electrode for touch detection. By integrating the switch contacts and indicator lamp mounting directly onto the metallic sheet, the design merges what were previously separate circuit board elements into a single space-efficient component.
2Area of stationary object
If touch switches are placed closer together to improve operability, then space is better utilized, but wiring layout becomes more complex
Solution Approach 1:
The patent extracts the wiring complexity from the metallic sheet structure by providing separate connection terminals on the circuit board. The metallic sheet contains integrated contacts that connect to these terminals, eliminating the need for complex wiring routes across the sheet itself, thus enabling closer switch placement without increasing wiring complexity.
Solution Approach 2:
The patent introduces connection terminals on the circuit board as intermediaries between the metallic sheet contacts and the internal circuitry. This intermediary approach simplifies the wiring layout by providing standardized connection points, allowing touch switches to be placed closer together without complicating the overall wiring structure.
