Solution Overview
Problem
Conventional position adjusting devices for integration rods in optical projector systems are complex in design, making them unsuitable for production using molds, due to the need for multiple adjusting screws and pins to fine-tune the rod's position along X and Y axes.
Innovation Solution
A position adjusting device with a single pin unit, featuring a base unit, a bracket, a connecting mechanism with resilient pins, and an eccentric screw adjusting member, allowing independent movement along both axes to fine-tune the integration rod's position, simplifying the structure and enabling mold-based production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple adjusting screws and pins are used to fine-tune the integration rod position along X and Y axes, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple adjusting screws and pins into a single integrated adjusting mechanism. The adjusting member integrates both X-axis and Y-axis adjustment functions, eliminating the need for separate adjusting screws and pins while maintaining positioning precision through its dual-axis capability design.
Solution Approach 2:
The adjusting member is designed as a multi-functional component that can adjust the integration rod position along both X and Y axes simultaneously. This universal adjusting mechanism replaces multiple specialized components, reducing device complexity while preserving full positioning capability.
2Measurement precision
If multiple adjusting screws and pins are used to fine-tune the integration rod position, then the positioning precision is improved, but the ease of manufacture deteriorates
Solution Approach 1:
By merging multiple adjusting components into a single adjusting member, the patent reduces the number of parts that need to be manufactured and assembled. This integration simplifies the manufacturing process, making the device more suitable for mold-based production while maintaining positioning precision.
Solution Approach 2:
The adjusting member is designed with segmented functional zones that correspond to X-axis and Y-axis adjustment capabilities. This segmentation allows for standardized manufacturing processes and mold designs, improving ease of manufacture while preserving multi-axis positioning precision.
3Measurement precision
If multiple adjusting screws and pins are arranged to fine-tune the mounting member position, then the positioning precision is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple adjusting screws and pins into a single integrated adjusting member that attaches to the mounting member. This consolidation reduces the number of components and their arrangements, simplifying the overall device structure while maintaining the capability to fine-tune position along both axes.

AI summary
A position adjusting device includes a base unit with spaced-apart first and second lateral plates. A bracket is elongated and interposed between the first and second lateral plates for mounting an integration rod, and includes opposite first and second open ends. A connecting mechanism includes two resilient pins connected respectively between the bracket and the first lateral plate and between the bracket and the second lateral plate. The resilient pins are proximate to the first open end of the bracket. An adjusting member extends through the first lateral plate, and abuts against one side of the bracket proximate to the second open end. The adjusting member drives the bracket to move along a first axis and a second axis perpendicular to the first axis. The first and second axes are perpendicular to an extension direction of the bracket.
