Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons, infrared receivers and indicator lights are installed on the front panel, then the display device can be controlled and status can be indicated, but the manufacturing complexity increases and aesthetics are affected
Solution Approach 1:
The patent combines the infrared receiver and indicator light into a single integrated component structure, where the infrared receiver and indicator light share the same housing and mounting position. This merging reduces the number of separate components that need to be installed and connected, thereby reducing manufacturing complexity while maintaining both control capability and status indication functions
Solution Approach 2:
The integrated component serves multiple functions: the infrared receiver receives remote control signals, the indicator light displays device status, and both are housed in a single unit that simplifies installation. This multi-functionality approach allows the device to maintain full operational capability while reducing overall structural complexity
2Ease of operation
If buttons, infrared receivers and indicator lights are installed on the front panel, then control and indication functions are provided, but production failure rate and production cost increase due to cable connections
Solution Approach 1:
By merging the infrared receiver and indicator light into a single integrated component, the patent reduces the number of cable connections required. The integrated component has consolidated wiring requirements, which reduces connection points potential failure sources during production and reduces overall production failure rate
Solution Approach 2:
The patent extracts the cable connection requirements from multiple separate components and consolidates them into a single integrated component with unified wiring. This extraction and consolidation approach reduces the total number of connections that need to be made during production, thereby reducing production failure rate and production cost
