Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If wiring regions are provided for each light detecting region in a conventional arrangement, then electrical connection is achieved, but the length of the light detecting element in the direction perpendicular to the light detection direction increases
Solution Approach 1:
The patent repositions wiring regions from a conventional one-to-one correspondence with light detecting regions to a concentrated arrangement at the end regions of the light detecting element. This spatial reconfiguration in the second direction (perpendicular to light detection direction) reduces the overall length of the element while maintaining all necessary electrical connections through strategic placement at boundaries.
Solution Approach 2:
Multiple wiring regions that would traditionally be distributed across the light detecting surface are merged and concentrated at the end regions. This consolidation allows multiple electrical connections to be made at localized positions, reducing the spatial footprint required for wiring arrangements while maintaining functional connectivity to all light detecting regions.
2Length of stationary object
If the light detecting element is made compact, then the height of the light emitting device is reduced, but the wiring arrangement becomes more difficult
Solution Approach 1:
The wiring regions are pre-positioned at the end regions of the light detecting element during the design phase. This preliminary arrangement of wiring positions simplifies the manufacturing process by providing predetermined, accessible locations for wire bonding or other electrical connections, eliminating the need for complex routing in compact configurations.
Solution Approach 2:
The end regions of the light detecting element serve as intermediary zones that facilitate electrical connections between the light detecting regions and external wiring. By concentrating wiring regions at these boundary positions, the patent creates natural connection points that simplify the manufacturing process while maintaining the compact overall dimensions of the device.
