Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a lamp bulb is used as the main heat source in the projector, then high illumination intensity is achieved, but high temperature is generated affecting performance and service life
Solution Approach 1:
The patent converts the harmful high temperature generated by the lamp bulb into a beneficial cooling mechanism by designing a reflective housing that directs hot air flow toward the lamp bulb, creating a natural convection cooling system that uses the heat itself to drive the cooling process
Solution Approach 2:
The patent employs air flow management through strategically designed air inlets, air outlets, and reflective surfaces to create controlled convection currents that carry heat away from sensitive components and direct it toward the lamp bulb for dissipation
2Loss of energy
If existing cooling solutions are used, then some heat dissipation is achieved, but effective heat management is insufficient
Solution Approach 1:
The patent segments the housing into multiple functional zones with dedicated air inlets and air outlets positioned at specific locations to create separate air flow paths for different cooling purposes, allowing independent optimization of cooling for various components
Solution Approach 2:
The patent applies local quality by creating region-specific cooling solutions within the housing, with reflective surfaces and air flow channels strategically positioned to target heat sources individually, providing enhanced cooling where needed most while maintaining overall thermal management

AI summary
A cooling device for an emitting module of a projector includes a base, a guiding portion installed on the base, and a latch portion installed on the base. The guiding portion includes a positioning plate secured on one side of the base and a guiding plate secured on the other side of the base. The positioning plate and the guiding plate are foldable relative to the base to be connected with each other and so define an inlet channel. Air flow can pass through the inlet channel to cool the emitting module. The latch portion is configured to form an outlet in different directions to adjust a direction and strength of the air flow.
