Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If light emitting elements are disposed in opposite directions to improve light emission efficiency, then light emission efficiency is improved, but electrical connection complexity increases
Solution Approach 1:
The patent combines multiple light emitting elements with opposite orientations into a single integrated structure, where shared electrodes and insulative films reduce overall complexity while maintaining high light emission efficiency from both directions
2Reliability
If insulative films are used to surround light emitting elements to prevent electrical short circuits, then reliability is improved, but manufacturing complexity increases
Solution Approach 1:
The insulative film serves multiple functions simultaneously: it provides electrical insulation between elements, structurally supports the opposite-direction configuration, and enables efficient light emission pathways, thereby improving reliability without proportionally increasing manufacturing complexity
3Manufacturing precision
If space between light emitting elements is filled with insulative material to minimize surface defects, then surface quality is improved, but manufacturing time increases
Solution Approach 1:
The insulative material is pre-formed and positioned before final assembly of the light emitting elements, allowing surface defects to be minimized in advance while reducing overall manufacturing time by avoiding post-assembly adjustments
