Innovation Solution
A color wheel module design featuring a housing module with a fastening device and electrical connector for quick detachment and assembly, allowing users to easily swap or replace color wheels with different specifications, and facilitating technicians to perform maintenance by enabling rapid disassembly and reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed color wheel module design is adopted, then the projector can maintain stable optical performance, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The color wheel module is segmented from the main projector body, creating an independent replaceable unit. The module includes a color wheel, housing, and electrical connector that can be detached as a complete assembly, allowing maintenance without disassembling the entire projector.
Solution Approach 2:
The color wheel module transitions from a fixed to a dynamic configuration, enabling it to be easily attached and detached. The electrical connector and fastening mechanism allow the module to be quickly replaced by users or technicians without complex procedures.
2Device complexity
If a fixed color wheel module is used, then the projector structure remains simple, but the adaptability for different applications decreases
Solution Approach 1:
The standardized color wheel module with uniform electrical connector and housing design can be applied across different projector models. This universal design allows the same module to serve multiple applications, from conference projectors to home entertainment systems, by simply replacing the module rather than purchasing different projectors.
Solution Approach 2:
The projector system becomes dynamically adaptable through the replaceable color wheel module. Users can switch between different color wheel configurations (e.g., 4-color for brightness, 3-color for color fidelity) by detaching and attaching different modules, enabling the same projector body to serve multiple application needs.
3Manufacturing precision
If the color wheel module is integrated into the projector, then the optical path is optimized, but the ease of repair and replacement deteriorates
Solution Approach 1:
The color wheel module is segmented as a complete sub-assembly including the color wheel, housing, and electrical connector. This segmentation maintains optimized optical path design within the module while enabling easy replacement of the entire module without affecting the main projector structure.
Solution Approach 2:
The electrical connector and fastening mechanism are pre-configured in the housing module to enable quick connection and disconnection. This preliminary preparation of the connection interface allows users or technicians to replace the color wheel module without requiring complex disassembly procedures or specialized tools.
