Optical Engine Adjustment Module for Precise Light-Source Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection devices face challenges in achieving precise alignment between the light source module and the optical engine module due to their fixed structures, which constrain alignment and increase difficulty.
Innovation Solution
An adjustment module is introduced that includes a substrate with adjustment components and screw holes, allowing the light source module to be moved relative to the optical engine module through rotation of adjustment elements, enabling quick and accurate alignment without structural constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If fixed structures are used for light source module and optical engine module, then structural stability is improved, but alignment precision deteriorates
Solution Approach 1:
The patent introduces an adjustment module with movable components including adjustment elements that can be rotated and adjusted relative to the substrate. This dynamic adjustment mechanism allows the light source module and optical engine module to be precisely aligned after assembly, resolving the contradiction between structural stability and alignment precision by enabling post-assembly adjustment while maintaining overall structural stability.
2Manufacturing precision
If adjustment components are added to enable alignment, then alignment precision is improved, but device complexity increases
Solution Approach 1:
The adjustment components are integrated into the existing module structure rather than being separate add-on elements. The adjustment elements are combined with the substrate and housing components, forming a unified assembly that provides alignment functionality without significantly increasing overall device complexity. This merging approach allows precise alignment while minimizing the increase in device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustment module facilitates rapid and precise alignment, reducing the impact of part tolerances and lowering the cost of parts by minimizing alignment constraints and tolerance requirements.
Implementation Method 1
a first head of the first adjustment element is rotatably positioned between the first limit piece and the first side wall, and the first head is exposed through the first opening of the first limit piece. A second head of the second adjustment element is rotatably positioned between the second limit piece and the second side wall
Implementation Method 2
The first adjustment element passes through the first through hole of the first side wall and threads with the first adjustment screw hole. A second adjustment element passes through the second through hole of the second side wall and threads with the second adjustment screw hole

AI summary
An adjustment module, an optical engine module, and a projection device including the adjustment module and optical engine module are disclosed. The projection device comprises a light source module that provides an illumination beam. The optical engine module receives the illumination beam and converts it into an image beam. The adjustment module is positioned between the light source module and the light entry portion of the optical engine module. The light source module is secured to a substrate of the adjustment module. The adjustment module includes the substrate, a first adjustment component, and a second adjustment component. By the first adjustment component, the adjustment module moves the light source module in a first extension direction, and by the second adjustment component, the adjustment module moves the light source module in a second extension direction, thereby aligning the light source module and optical engine module.
