Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light source parts are arranged in a fixed pattern, then the device structure is simple, but the illumination pattern flexibility is limited
Solution Approach 1:
The light source device is divided into multiple independently controllable light source parts, each with its own light-emitting element and light guiding member. This segmentation allows each unit to be controlled individually, enabling flexible illumination patterns without requiring complex overall reconfiguration of the entire light source array.
Solution Approach 2:
The patent implements dynamic control of light source parts through individual intensity adjustment and selective activation. The control unit can dynamically change which light source parts are active and at what intensity levels, allowing the illumination pattern to adapt to different requirements while maintaining a fixed physical arrangement of light source components.
2Manufacturing precision
If light guiding members are added to each light source part, then illumination control precision is improved, but device complexity increases
Solution Approach 1:
The light guiding member is integrated with each light-emitting element to form a unified light source part. This merging of the light-emitting element and light guiding member into a single modular unit simplifies the overall structure while maintaining precise illumination control, as each integrated unit functions as a complete building block.
Solution Approach 2:
The light guiding member serves multiple functions: it guides light from the light-emitting element, shapes the illumination pattern, and can be individually controlled to achieve different illumination effects. This multi-functionality reduces the need for additional separate components, thereby controlling device complexity while improving illumination precision.
3Productivity
If individual light source parts are controlled independently, then illumination efficiency is improved, but control system complexity increases
Solution Approach 1:
The control system can activate only the necessary subset of light source parts required for a given illumination task, rather than operating all light sources simultaneously. This partial action approach improves illumination efficiency by reducing energy consumption and heat generation while maintaining effective illumination, and the modular control architecture manages complexity through hierarchical control levels.
