Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing projector designs with laser light source modules are complicated, making the replacement process time-consuming and costly, requiring disassembly of multiple components, which leads to low assembly yield and increased complexity.
Innovation Solution
A projector design featuring a laser module with a positioning member and a laser unit that can be easily separated from the optical engine and heat dissipation modules, utilizing a positioning groove for simple insertion and removal, reducing the need for full disassembly of other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the laser light source module is assembled and fixed together with the heat dissipation module and the optical engine module, then the projector structure is stable, but the replacement process becomes complicated and time-consuming
Solution Approach 1:
The laser light source module is segmented from the heat dissipation module and optical engine module, allowing independent replacement of the laser module without disassembling the entire projector structure. The positioning member with positioning groove enables modular assembly where the laser module can be independently installed and removed.
Solution Approach 2:
The laser light source module is extracted as a separate replaceable component from the integrated assembly. The positioning member structure allows the laser module to be taken out and replaced independently while maintaining the stability of the remaining projector structure.
2Stability of the object's composition
If the laser light source module is integrated with other modules, then the projector structure is stable, but the disassembly and assembly process becomes complicated
Solution Approach 1:
The positioning member is designed with distinct components (main body, positioning groove, fixing structure) that enable segmented assembly. The laser module can be positioned and fixed through simple sequential steps without complex disassembly of the entire projector structure.
3Ease of repair
If the laser light source module is replaced by removing multiple components, then the laser module can be accessed, but the replacement time and cost increase
Solution Approach 1:
The laser light source module is extracted as an independently accessible component through the positioning member structure. The positioning groove and fixing mechanism allow the laser module to be removed and replaced without time-consuming disassembly of surrounding components.
