Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the heat dissipating device is bolted onto the casing, then the heat dissipation function is achieved, but the device suffers from wobbling resulting in degraded imaging quality
Solution Approach 1:
The heat dissipating module is divided into multiple parts: the heat dissipating device, the heat dissipating sheet, and the compensating module. Each part has specific functions - the heat dissipating device conducts heat from the light valve, the heat dissipating sheet transfers heat to the compensating module, creating a segmented heat dissipation path that improves both efficiency and stability
Solution Approach 2:
The compensating module is designed to perform multiple functions simultaneously: it acts as an optical compensating sheet for image quality correction, a heat dissipating component for thermal management, and a stabilizing structure for the heat dissipating device. This merging of functions eliminates the need for separate components and reduces wobbling
2Temperature
If heat dissipating sheets are disposed to conduct heat from the light valve, then heat dissipation is improved, but the cost increases due to additional components
Solution Approach 1:
The compensating module integrates multiple functions into a single component: optical compensation, heat dissipation, and structural support. By combining these functions, the patent eliminates the need for separate heat dissipating sheets and other auxiliary components, thereby reducing device complexity and cost while maintaining effective heat dissipation
Solution Approach 2:
The compensating module is designed as a multi-functional component that simultaneously serves as an optical compensating sheet, a heat dissipating device, and a structural support element. This universality reduces the total number of components needed in the system, lowering both complexity and cost
3Stability of the object's composition
If the heat dissipating module is securely connected to the casing, then stability is improved, but the device complexity increases due to additional fixing structures
Solution Approach 1:
The compensating module serves multiple purposes including providing fixing structures for securing the heat dissipating device, acting as an optical compensating sheet, and functioning as a heat dissipating component. By making the compensating module multi-functional, the patent avoids adding separate fixing structures, thus maintaining stability without significantly increasing device complexity
