Light Path Adjustment Mechanism Asymmetric Flexible Member Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional light path adjustment mechanisms are bulky, heavy, and difficult to miniaturize due to their large number of components and occupied space, which hinders the miniaturization of image display devices.
Innovation Solution
A compact light path adjustment mechanism is designed using a carrier, optical plate member, support, base, and flexible members with actuators, where the first pair of flexible members and actuators are disposed on one side of the optical plate member, reducing the length of the second pair of flexible members and allowing for a thinner optical module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light and increase addressability, then image resolution and picture quality are improved, but the number of components, weight and occupied space become considerably large
Solution Approach 1:
The patent merges multiple transmission mechanical pieces into a single integrated flexible member structure. The flexible member contains multiple reflection surfaces that perform the functions of separate mechanical components, thereby reducing the total number of parts while maintaining the light path adjustment capability needed for high image resolution.
Solution Approach 2:
The flexible member serves multiple functions simultaneously: it acts as both a structural support element and a light path adjustment mechanism with multiple reflection surfaces. This multi-functional design eliminates the need for separate components, reducing device complexity while preserving image quality enhancement capabilities.
2Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light and increase addressability, then image resolution and picture quality are improved, but weight and occupied space become considerably large
Solution Approach 1:
By combining multiple functional elements into a single flexible member, the overall mass of the mechanism is reduced. The integrated structure eliminates redundant materials and components, achieving weight reduction while maintaining the light path adjustment functionality required for high image resolution.
3Measurement precision
If a conventional light path adjustment mechanism is used to adjust propagation paths of light and increase addressability, then image resolution and picture quality are improved, but the entire mechanism is difficult to be miniaturized
Solution Approach 1:
The integration of multiple transmission mechanical pieces into a single flexible member dramatically reduces the volume occupied by the mechanism. This consolidated structure allows for compact packaging and miniaturization of the overall device while preserving the light path adjustment capabilities necessary for high image resolution.
Solution Approach 2:
The flexible member with its multiple reflection surfaces creates a nested functional structure where multiple light path adjustment functions are contained within a single compact element. This nesting approach enables miniaturization by fitting multiple functions into a reduced spatial envelope.
4Length of stationary object
If the first pair of flexible members and actuators are disposed on one side of the optical plate member, then the length of the second pair of flexible members is reduced and the optical module becomes thinner, but the structural design becomes more constrained
Solution Approach 1:
The patent employs an asymmetric arrangement where the first pair of flexible members and actuators are positioned on one side of the optical plate member, while the second pair is positioned on the opposite side. This asymmetric configuration optimizes the height by reducing the length of the second pair of flexible members, achieving a thinner optical module through deliberate asymmetric design rather than symmetric distribution.

AI summary
A light path adjustment mechanism includes a carrier, an optical plate member, a support, a base, a first pair of transmission mechanical pieces, and a second pair of transmission mechanical pieces. One side of the support is provided with a first actuator, and one side of the base is provided with a second actuator. The first pair of transmission mechanical pieces are connected between the base and the support, and the second pair of transmission mechanical pieces are connected between the carrier and the support. The first pair of transmission mechanical pieces are entirely disposed on only one side of the carrier.
