Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light-pipe adjusting apparatuses lack precision and reliability in adjusting the position of light-pipes within optical-mechanical systems, leading to potential deviations in light homogenization and quality issues in projection screens.
Innovation Solution
A light-pipe adjusting apparatus featuring a first support with a light-pipe component slidably connected via a first rail, driven by a first drive device, allowing accurate movement along a designed path without deflection, and including a second support with a perpendicular rail for independent adjustments, ensuring precise positioning and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a bolt and elastic member clamping mechanism is used to adjust light-pipe position, then the light-pipe can be positioned and adjusted radially, but the adjustment precision is insufficient and the light-pipe may deflect during movement
Solution Approach 1:
The patent replaces the traditional bolt-and-elastic-member clamping mechanism with a rail-guided sliding mechanism. The light-pipe component slides along a precisely manufactured rail under gravity, eliminating the need for complex clamping forces while achieving high positioning precision and preventing deflection through the rail's geometric constraints.
Solution Approach 2:
The patent transforms the static clamping adjustment mechanism into a dynamic gravity-driven sliding system. The light-pipe component moves freely along the rail under gravitational force, allowing continuous precise positioning without the discrete steps or force-dependent precision of the bolt mechanism.
2Adaptability or versatility
If a single rail system is used for light-pipe adjustment, then the structure is simple, but the adjustment is limited to one direction and cannot accommodate multi-dimensional positioning requirements
Solution Approach 1:
The patent extends the adjustment system from one dimension to three dimensions by adding a second perpendicular rail system. The first rail enables adjustment in one direction, while the second perpendicular rail enables adjustment in the orthogonal direction, achieving comprehensive multi-dimensional positioning capability.
Solution Approach 2:
The patent divides the adjustment system into independent modular rail units. Each rail system operates independently in its own direction, allowing the complex multi-dimensional adjustment task to be segmented into simpler one-dimensional movements along each rail axis.
