Projector Stand with Elastic Vibration Damping to Reduce Image Swing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector systems experience deterioration in visibility due to frame vibrations, which are directly transmitted to the projector, causing significant swing motion of the projected image light.
Innovation Solution
A stand and adapter system that includes a placement table, a leg for support, a power supplier, and an elastic part between the placement table and the projector, with an adapter featuring first and second terminals for power supply and an extension with an elastic part to suppress vibrations, allowing the projector to be securely mounted and reducing image light swing motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the projector is directly placed on the placement table, then the structure is simple, but the frame vibration is directly transmitted to the projector causing large swing motion of projected image light
Solution Approach 1:
The patent introduces an elastic part as an intermediary component between the placement table and the projector. This elastic part acts as a mediator that absorbs and dampens vibrations from the placement table, preventing them from being directly transmitted to the projector. The elastic part serves as a buffer zone that reduces the harmful vibrational effects while maintaining the overall simplicity of the structure.
Solution Approach 2:
The elastic part is pre-installed between the placement table and the projector to provide beforehand cushioning against vibrations. This cushioning mechanism is prepared in advance to absorb and mitigate vibrational shocks before they can affect the projector and cause image light swing motion, thereby protecting the system from harmful vibrations.
2Object-affected harmful factors
If the elastic part is added between the placement table and the projector, then the vibration transmission is reduced, but the device complexity increases
Solution Approach 1:
The elastic part serves as a simple intermediary component that effectively reduces vibration transmission without requiring complex mechanical structures. By using this single elastic element as a mediator, the patent achieves vibration suppression while maintaining relative structural simplicity, avoiding the need for complex damping systems or multiple components.
