Projector Light Source Holding Member and Base Member Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light source apparatuses for projectors, which integrate the holder and base member as a single component, face issues such as decreased yield due to stringent processing accuracy requirements and increased costs due to the necessity of using expensive materials with high thermal conductivity for both components.
Innovation Solution
The light source apparatus is designed with a separate holding member and base member, allowing for the selection of optimal materials and processing accuracies for each component. The holding member, which holds the wavelength conversion member, is made of a material with high thermal conductivity, while the base member can be made of a less expensive material with lower thermal conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the holder and base member are integrated as a single component, then the structural complexity is reduced, but the manufacturing precision requirement increases and yield decreases
Solution Approach 1:
The patent divides the integrated holder-base member structure into two separate components: a holder that holds the wavelength conversion member and a base member that supports the light emitter. This segmentation allows each component to be manufactured and processed independently, so that high precision is only required for the holder's groove while the base member can be manufactured with lower precision requirements, thereby improving overall yield without significantly increasing structural complexity.
2Adaptability or versatility
If the holder and base member are integrated as a single component, then the material selection is unified, but the cost increases due to the necessity of using expensive high thermal conductivity materials throughout
Solution Approach 1:
The patent applies different material properties to different components based on their specific functional requirements. The holder, which requires high thermal conductivity for efficient heat dissipation from the wavelength conversion member, is made of an expensive material with high thermal conductivity. The base member, which has less stringent thermal requirements, is made of a less expensive material. This local differentiation of material quality reduces overall production cost while maintaining the necessary thermal performance where it is most critical.
