Optical Path Adjusting Mechanism for High-Resolution Projection

The patent applies the dynamics principle by making the light valve movable rather than fixed. The light valve is positioned on a movable stage that can be dynamically adjusted along the optical axis and laterally, allowing a lower-resolution light valve to project higher-resolution images by optimizing its position and angle relative to the projection lens. This dynamic positioning capability resolves the contradiction by enabling high-resolution projection without requiring expensive high-resolution display elements.

The patent employs parameter changes by adjusting multiple parameters of the light valve including its position along the optical axis, lateral position, and tilt angle. By changing these parameters, the system can achieve optimal projection quality with a lower-resolution light valve. The movable stage and adjustment mechanisms enable precise control of these parameters, allowing the same light valve to achieve different effective resolutions depending on its configured position and orientation.

The patent applies the universality principle by designing the movable stage to perform multiple functions simultaneously. The same stage structure provides both axial positioning and lateral positioning capabilities, as well as tilt adjustment. This multi-functional design reduces the need for separate adjustment mechanisms for each degree of freedom, thereby managing device complexity while achieving precise control over the light valve position and orientation for high-resolution projection.

The patent employs the nested doll principle by integrating multiple adjustment mechanisms within a hierarchical stage structure. The movable stage contains nested components where finer adjustment mechanisms are integrated within coarser positioning structures. This nested arrangement allows compact integration of multiple adjustment functions (axial position, lateral position, tilt angle) in a space-efficient manner, managing device complexity while maintaining precise control capabilities.
