Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat dissipation structures are added to manage heat from light sources, then heat dissipation effectiveness is improved, but device complexity increases
Solution Approach 1:
The patent combines the heat dissipation holder and light converter holder into a single integrated structure. The heat dissipation holder includes a holder body that accommodates the light converter, eliminating the need for separate heat dissipation and light converter holding structures. This merging reduces overall device complexity while maintaining effective heat dissipation from the light sources.
Solution Approach 2:
The heat dissipation holder serves multiple functions: it holds the light converter in position, provides thermal pathways for heat dissipation from both the light sources and light converter, and structures the arrangement of optical components. This multi-functionality reduces the number of separate components needed, thereby reducing device complexity while improving heat dissipation effectiveness.
2Productivity
If light converter is exposed to light sources, then light conversion efficiency is improved, but heat damage risk increases
Solution Approach 1:
The patent introduces a reflective plate as an intermediary between the light sources and light converter. The reflective plate is positioned to reflect light from the light sources toward the light converter while simultaneously providing a thermal barrier that prevents direct heat transfer to the light converter. This intermediary structure enables the light converter to be exposed to light for efficient conversion while protecting it from heat damage.
Solution Approach 2:
The patent segments the spatial arrangement by positioning the reflective plate between the light sources and light converter, creating distinct optical and thermal zones. This segmentation allows the light converter to receive sufficient light exposure for efficient conversion while being thermally isolated from the heat-generating light sources through the reflective plate barrier.
3Temperature
If multiple heat dissipation components are used, then heat dissipation performance is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple heat dissipation functions into a single integrated heat dissipation holder structure. Rather than using separate heat dissipation components for different parts of the system, the holder body provides unified thermal management for both the light sources and light converter through its integrated design, reducing manufacturing complexity and cost.
Solution Approach 2:
The heat dissipation holder is designed as a universal component that performs multiple heat dissipation functions simultaneously - managing heat from light sources, supporting the light converter, and providing thermal pathways. This multi-functionality eliminates the need for multiple specialized heat dissipation components, thereby reducing manufacturing cost while maintaining effective heat dissipation performance.
