Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical modules in projectors are not adjustable, leading to potential optical variations due to mechanical tolerances, which can affect the desired optical effect.
Innovation Solution
An adjustable optical module is designed with a carrier, frame, base, and dual adjusting assemblies, allowing the optical element to be pivoted around two axes, enabling precise adjustment of the optical path for improved performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the optical module is fixed at a specific position, then the structure is simple, but the optical effect is affected due to mechanical tolerance
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed optical module into an adjustable one. The optical element is mounted on a carrier that can rotate around a first axis, and the entire assembly can rotate around a second axis. This dynamic structure allows the optical element to be adjusted to different positions and angles, compensating for mechanical tolerance errors and ensuring consistent optical effect.
2Reliability
If the optical module is made adjustable, then the optical effect consistency is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the adjustment function into two independent rotational movements. The first rotation around the first axis is controlled by a first adjusting assembly, and the second rotation around the second axis is controlled by a second adjusting assembly. This segmentation allows each adjustment mechanism to be simple and independent, reducing overall complexity while achieving precise optical element positioning.
3Measurement precision
If dual adjusting assemblies are added, then the adjustment precision is improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies universality by designing the first and second adjusting assemblies with similar structures. Both assemblies include a driving member, an adjusting member, and a rotating member, allowing for standardized manufacturing processes and interchangeable components. This multi-functionality approach simplifies production while maintaining high adjustment precision through dual-axis control.

AI summary
Provided are an adjustable optical module and a projector including the same. The adjustable optical module includes an optical element; a carrier; a frame; a base; a first adjusting assembly including a first driving member, a first adjusting member, and a first rotating member; and a second adjusting assembly including a second driving member, a second adjusting member, and a second rotating member. The first adjusting member is adjusted to drive a first boss of the first driving member to move, the first rotating member being correspondingly driven to rotate, thereby pushing the carrier to rotate around a first axis relative to the base. The second adjusting member is adjusted to drive a second boss of the second driving member to move, the second rotating member being correspondingly driven to rotate, thereby pushing the frame to rotate around a second axis relative to the base.
