Solution Overview
Problem
Existing optical modules and projectors face challenges in quickly, simply, and accurately adjusting the rotation angle of optical components, which affects the optimization of brightness and color temperature of emitted light beams.
Innovation Solution
The optical module design includes a first frame body, a second frame body, a first adjustment member, and a first optical component, where the first frame body is rotatably connected to a base body with a boss and adjustment portion, and the second frame body is connected to the first frame body with a second adjustment portion, allowing the first adjustment member to drive both frame bodies to rotate along distinct axes, enabling precise adjustment of the optical component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional adjustment methods are used for optical components, then the adjustment process becomes complex and time-consuming, but the rotation angle cannot be adjusted quickly and accurately
Solution Approach 1:
The adjustment mechanism is divided into two independent rotational stages: the first frame body rotates relative to the base body around a first axial line, and the second frame body rotates relative to the first frame body around a second axial line. This segmentation allows each stage to be adjusted independently, simplifying the overall adjustment process while maintaining high precision for both brightness and color temperature optimization.
Solution Approach 2:
The patent introduces a dual-axis rotational system where the first frame body and second frame body rotate around different axial lines (first axial line and second axial line respectively). This dimensional change from single-axis to multi-axis adjustment enables independent control of optical component orientation, achieving quick and accurate rotation angle adjustment without increasing mechanism complexity.
2Productivity
If manual adjustment of optical component angles is performed, then the adjustment process is simple in structure, but it is time-consuming and lacks accuracy
Solution Approach 1:
The adjustment mechanism transforms from static manual positioning to dynamic multi-stage rotational adjustment. The first frame body can rotate dynamically around the first axial line, and the second frame body can rotate dynamically around the second axial line, allowing rapid and precise adjustment of the optical component's orientation to optimize brightness and color temperature.
Solution Approach 2:
The first frame body acts as an intermediary between the base body and the second frame body. It provides a stable rotation platform around the first axial line, while the second frame body rotates around the second axial line relative to the first frame body. This intermediary structure enables coordinated dual-axis adjustment, improving both adjustment speed and precision.
