Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector technologies face challenges in accurately adjusting the angle of the projection lens, leading to laborious and time-consuming error measurements and potential shaking due to elastic deformation, especially when using gaskets or bolt displacement methods.
Innovation Solution
A projector with a projection lens adjusting module that includes a first screw fitting member and a stop structure, allowing the projection lens to be clamped and adjusted relative to a base, preventing unexpected shaking by leveraging a compressed elastic member and adhesives for stable fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the projection lens angle is adjusted using a gasket, then the angle can be compensated, but the measurement and arrangement process becomes laborious and time-consuming
Solution Approach 1:
The patent pre-configures the projection lens at a default correct angle during manufacturing. The lens mounting structure includes pre-set adjustment mechanisms that allow the lens to be positioned accurately without requiring field measurement and gasket arrangement. This preliminary positioning action eliminates the need for time-consuming angle measurement and gasket selection during deployment.
2Ease of operation
If the projection lens angle is adjusted through bolt rotation with spring elastic force, then the lens can be adjusted, but the projection lens becomes easy to shake
Solution Approach 1:
The patent divides the lens mounting system into separate functional components: an adjustment mechanism for angle modification and a fixation mechanism for stable positioning. The adjustment mechanism allows controlled lens angle changes, while the fixation mechanism locks the lens in place to prevent shaking. This segmentation separates the functions of adjustment and stabilization, allowing each to perform its specific function effectively without interfering with the other.
3Measurement precision
If repeated error measurement and gasket arrangement is performed, then the angle error can be compensated, but the process becomes very laborious
Solution Approach 1:
The patent implements a self-aligning lens mounting structure that automatically positions the projection lens at the correct angle without requiring external measurement tools or complex adjustment procedures. The mounting mechanism includes built-in alignment features such as indexed adjustment holes and corresponding positioning pins that guide the lens into the correct orientation automatically, eliminating the need for repeated manual measurement and gasket arrangement.

AI summary
A projection lens adjusting module including at least one adjusting assembly and a base is provided. The at least one adjusting assembly includes a first screw fitting member and a stop structure. The stop structure has a first stop portion and a second stop portion opposite to each other, the first screw fitting member leans against the first stop portion, and a part of a projection lens is clamped between the first screw fitting member and the second stop portion. The first screw fitting member is screwed to the base and is configured to rotate relative to the base, so as to drive the adjusting assembly and the projection lens to move relative to the base. A projector using the aforementioned projection lens adjusting module is also provided. The projection lens adjusting module and the projector of the disclosure are capable of stably fixing the projection lens.
