Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illumination systems in projection devices require multiple elements to adjust the position of optical elements, leading to complexity and inefficiency in light usage optimization.
Innovation Solution
An adjusting module comprising an optical element, a first frame with a wedge structure, a second frame, elastic members, and adjusters that allow for precise horizontal displacement and rotational adjustment of the optical element by leveraging a wedge structure and screw mechanisms, reducing the number of components needed while maintaining adjustment effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple elements are used to adjust the position of the optical element, then the adjustment effectiveness is maintained, but the device complexity increases
Solution Approach 1:
The patent combines multiple adjustment functions (horizontal position adjustment and rotational angle adjustment) into a single integrated adjusting device. The adjusting device includes a movable platform for horizontal displacement and a rotating platform for angular adjustment, both controlled by the same adjusting mechanism, thereby reducing the number of separate elements while maintaining comprehensive adjustment effectiveness
Solution Approach 2:
The adjusting device is designed to perform multiple functions simultaneously: it can adjust the horizontal position of the optical element through the movable platform, and it can adjust the rotational angle through the rotating platform. This multi-functional design allows a single device to replace what would traditionally require multiple separate adjustment elements
2Measurement precision
If multiple elements are used to adjust the position of the optical element, then the adjustment precision is maintained, but the light usage efficiency decreases
Solution Approach 1:
The patent extracts and eliminates redundant adjustment elements from the traditional multi-element system. By using a streamlined adjusting device with a movable platform and rotating platform, it achieves the necessary adjustment precision without the overhead of multiple separate components, thereby improving light usage efficiency by reducing optical path losses and reflections from unnecessary elements
