Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If uniform wiring configurations are used for all light emitting units, then the structure is simple and easy to manufacture, but the arrangement flexibility of light emitting units is restricted and variations in light quantity and emission timing occur
Solution Approach 1:
The light emitting units are divided into two groups (first light emitting units and second light emitting units) with different wiring configurations. The first wiring connects first light emitting units directly through semiconductor layers, while the second wiring connects second light emitting units through insulating layers. This segmentation allows each group to have optimized wiring paths, improving arrangement flexibility while maintaining manufacturing simplicity through standardized connection methods for each group.
Solution Approach 2:
Different wiring configurations are applied to different locations in the light emitting array. First light emitting units use a wiring structure optimized for their position, while second light emitting units use a different wiring structure suited to their location. This local differentiation resolves the contradiction by allowing manufacturing simplicity through standardized local patterns while achieving overall arrangement flexibility through the combination of different local configurations.
2Productivity
If staggered arrangement of light emitting units is implemented, then arrangement flexibility and light emission efficiency are improved, but wiring configuration complexity increases
Solution Approach 1:
The staggered arrangement is managed by segmenting the wiring into two distinct types: first wiring for first light emitting units and second wiring for second light emitting units. Each wiring type follows a standardized pattern appropriate for its associated light emitting units, which reduces the overall complexity compared to creating unique wiring paths for each individual unit in the staggered arrangement.
Solution Approach 2:
Multiple first light emitting units are connected through common first wiring paths, and multiple second light emitting units are connected through common second wiring paths. This merging approach reduces the total number of independent wiring configurations needed, thereby reducing complexity while still supporting the staggered arrangement that improves light emission efficiency.
3Manufacturing precision
If different wiring configurations are used for first and second light emitting units, then arrangement flexibility and control precision are improved, but manufacturing complexity increases
Solution Approach 1:
The different wiring configurations are implemented as localized patterns that can be manufactured using standardized processes. The first wiring configuration is optimized for first light emitting units and the second wiring configuration is optimized for second light emitting units, but both follow repeatable manufacturing patterns. This allows manufacturing precision to be improved through optimized local configurations while keeping manufacturing complexity manageable through standardization.
Solution Approach 2:
The wiring design uses universal connection methods for each group type. The first wiring structure serves all first light emitting units, and the second wiring structure serves all second light emitting units. This universality within each group reduces manufacturing complexity by allowing the use of standardized manufacturing processes for each wiring type, even though the two wiring types differ from each other to achieve the desired control precision.
