Integrating Light Source into Mirror Housing for Compact Optical Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing optical devices, such as projectors and copiers, are bulky due to the separate arrangement of the light source and mirror element housing body, making it difficult to downsize them.
Innovation Solution
Integrating the light source within the mirror element housing body, which accommodates and seals the mirror element, allowing for a more compact design by eliminating the need for a support member and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the light source is arranged separately from the mirror element housing body, then the light source can be easily replaced and maintained, but the overall device size increases
Solution Approach 1:
The patent combines the light source with the mirror element housing body by providing the light source inside the housing body, integrating two previously separate components into one unified structure, thereby reducing overall device size while maintaining functionality
2Volume of moving object
If the light source is integrated inside the mirror element housing body, then the device size is reduced, but the light source becomes harder to access for maintenance
Solution Approach 1:
The patent extracts the light source from its traditional separate position and places it inside the mirror element housing body, repositioning the component to achieve compact integration while the housing body structure provides access pathways for maintenance
3Stability of the object's composition
If separate support members are used to hold the light source, then the light source positioning is stable, but the device complexity and size increase
Solution Approach 1:
The mirror element housing body serves multiple functions: it houses the mirror element, seals the optical space, and simultaneously provides support and positioning for the light source, eliminating the need for separate support members and reducing structural complexity
Applied Scientific Principles
