Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source apparatus uses a fixed integrated structure, then the manufacturing and assembly are simpler, but the adaptability to specification changes is poor
Solution Approach 1:
The light source apparatus is divided into multiple independent units: a light source unit containing the laser light source, an optical system unit containing optical components, and a phosphor unit containing the phosphor wheel. These units can be independently designed, manufactured, and assembled, enabling flexible specification changes while maintaining manageable complexity through modular architecture.
2Adaptability or versatility
If the light source apparatus uses a modular design with separate units, then the adaptability to specification changes is improved, but the device complexity increases
Solution Approach 1:
The modular units are designed with universal connection interfaces and standardized mounting structures that allow different specifications of light source units, optical system units, and phosphor units to be interchangeably assembled. This universality reduces the complexity burden by providing standardized connection protocols across all unit types.
3Reliability
If the light source apparatus has open structures for heat dissipation and access, then the ease of manufacture and maintenance is improved, but dust and contaminants can affect the optical components
Solution Approach 1:
Each modular unit is enclosed in a casing that provides dustproof protection for internal optical components. The casings include sealed structures with light-transmitting windows that allow optical paths to remain protected while maintaining unit integrity. These flexible enclosure designs enable easy assembly and disassembly for maintenance while consistently providing dustproof protection.
