Problem
Conventional light path adjustment mechanisms are bulky, heavy, and occupy significant space, making them difficult to miniaturize, which hinders the improvement of image resolution and picture quality in image display devices.
Innovation Solution
A light path adjustment mechanism comprising a support, a carrier, an optical plate member, and actuators connected via elastic members, allowing the optical plate member to tilt about two distinct axes through the interaction of acting forces and resilient forces, reducing occupied space, weight, and component count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light, then image resolution and picture quality are improved, but the number of components, weight and occupied space are considerably large
Solution Approach 1:
The patent combines multiple light path adjustment functions into a single integrated optical element that can tilt about two distinct axes. The carrier structure integrates the support for the optical plate member with the elastic member connections, merging what would traditionally be separate components into a unified assembly that reduces overall component count while maintaining light path adjustment capability.
Solution Approach 2:
The optical plate member is designed to perform multiple functions simultaneously: it serves as both the optical element for light path adjustment and the structural carrier for mounting actuators. The elastic members provide both mechanical support and restoring force functions. This multi-functionality reduces the number of dedicated components needed for each function.
2Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light, then image resolution and picture quality are improved, but weight and occupied space are considerably large
Solution Approach 1:
The patent employs elastic members that function as flexible mechanical elements to connect the carrier to the support. These elastic members replace rigid structural components, significantly reducing the weight of the moving parts while maintaining the necessary mechanical support and restoring forces for the optical plate member's tilting motion.
Solution Approach 2:
The optical plate member is designed with dynamic tilting capability about two distinct axes, allowing it to adjust light paths in multiple directions. This dynamic design replaces what would traditionally require multiple fixed optical elements or a more complex mechanical structure, thereby reducing overall weight while maintaining full light path adjustment functionality.
3Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light, then image resolution and picture quality are improved, but the entire mechanism is difficult to be miniaturized
Solution Approach 1:
The patent implements a nested structure where the optical plate member is mounted on the carrier, which is in turn connected to the support via elastic members. The actuators are positioned to work within the spatial envelope defined by the carrier and optical plate member assembly. This nested arrangement allows compact packaging of multiple functional elements, enabling miniaturization while preserving light path adjustment capability.
Solution Approach 2:
The optical plate member tilts about two distinct axes, utilizing angular displacement in multiple dimensions to achieve light path adjustment. This dimensional approach to light path control replaces what would traditionally require linear displacement of multiple separate elements, significantly reducing the occupied space and enabling compact design.
