Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are mounted on circuit boards using conventional methods, then mounting can be achieved, but mounting accuracy deteriorates over time and reliability decreases
Solution Approach 1:
The device is divided into separate functional components: a body portion, a reflective insert, and a light-emitting element. This segmentation allows each component to be optimized independently and assembled with precise positioning features, maintaining mounting accuracy while improving overall reliability
Solution Approach 2:
The reflective insert is pre-positioned within the body portion with precise positioning features before the light-emitting element is mounted. This preliminary action ensures that when the device is assembled and mounted on the circuit board, the optical alignment is already established, maintaining accuracy over time
2Adaptability or versatility
If devices are mounted in various orientations, then versatility is improved, but mounting difficulty increases
Solution Approach 1:
The device employs asymmetric positioning features including a specific arrangement of leads and a non-symmetric reflective insert configuration. This asymmetry provides natural alignment cues that guide correct orientation during mounting, making the device versatile for different orientations while actually simplifying the mounting process through self-alignment
Solution Approach 2:
The device includes self-aligning features such as the reflective insert positioned relative to the light-emitting element and lead arrangement that automatically indicates correct orientation. This self-service mechanism guides the mounting process, making it easier to achieve correct orientation regardless of the intended mounting direction
