Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If adjusting screws are used to adjust the position of the integration rod, then the position adjustment function is achieved, but the adjusting screws interfere with other components inside the housing and require disassembly and additional tools for operation
Solution Approach 1:
The invention extracts the position adjustment function from the traditional adjusting screw mechanism and relocates it to a dedicated adjustment element with a cam structure. This adjustment element can be independently operated without disassembling the entire optical engine, eliminating the need for additional tools and reducing interference with other components.
Solution Approach 2:
The invention introduces a cam structure as an intermediary mechanism between the adjustment element and the integration rod. The cam structure converts rotational motion into linear displacement, enabling precise position adjustment without requiring direct access to adjusting screws inside the housing.
2Ease of operation
If additional adjusting tools are introduced to achieve position adjustment, then the adjustment function is enhanced, but the number of components increases and fabrication costs increase
Solution Approach 1:
The invention merges the adjustment element, cam structure, and positioning mechanism into a single integrated component. This unified design eliminates the need for separate adjusting tools and reduces the total component count, thereby simplifying the fabrication process and reducing costs.
3Measurement precision
If the entire optical engine is disassembled for position adjustment, then access to the integration rod is improved, but the operational convenience is reduced and potential damage to components may occur
Solution Approach 1:
The invention segments the optical engine into functional modules, with the adjustment element positioned to access the integration rod independently. This modular design allows position adjustment to be performed on the integration rod without disassembling the entire optical engine, maintaining both precision and operational convenience.

Implementation Method 1
the actuator leans against one side of the light-homogenizing device and has a plurality of curved surfaces with different radii of curvature. When the actuator rotates, different curved surfaces push the light-homogenizing device to cause the light-homogenizing device to move in at least one direction from an initial position
