Projector Support Bracket Using Gear-Thread Pitch Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector adjustment mechanisms require users to lift the device to adjust the height, leading to inconvenient and inaccurate adjustments, causing deviations in the projector's placement.
Innovation Solution
An adjustment bracket with a gear transmission and thread system, where an adjustment roller engages with an adjustment foot gear, allowing for precise adjustment of the projector's pitch angle or height through a screw joint of internal and external threads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a supporting foot with telescopic adjustment is used, then the height adjustment function is achieved, but the user must lift the projector which causes inconvenient operation and placement position deviation
Solution Approach 1:
The patent introduces an adjustment bracket as an intermediary component between the projector and the supporting foot. This bracket includes a roller that can rotate independently, allowing the foot to be adjusted without lifting the projector. The intermediary bracket absorbs the adjustment motion, enabling the user to adjust the height by rotating the roller while the projector remains stationary on the surface.
2Measurement precision
If manual lifting and foot adjustment is used, then height adjustment is possible, but the adjustment precision is poor and placement position deviates
Solution Approach 1:
The patent replaces the manual lifting and grasping mechanism with a roller-based mechanical system. The roller provides controlled rotational motion that translates into precise linear adjustment of the supporting foot. This mechanical substitution eliminates the need for manual lifting and provides precise, repeatable adjustment increments through the roller's rotation, significantly improving adjustment precision while maintaining ease of operation.
