Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun sight adjustment mechanisms for LED light sources suffer from mutual interference between pitch and left-right angle adjustments, leading to low precision and instability, complicating the design and increasing costs.
Innovation Solution
An adjustment mechanism that integrates transverse and vertical adjustments using a sliding block, wedge-shaped block, and spiral springs to allow simultaneous fine tuning of pitch and left-right angles, reducing the number of mechanisms and simplifying the design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If independent adjustment mechanisms are used for pitch angle and left-right angle, then each adjustment can be operated separately, but mutual influence occurs between the two adjustments, affecting precision and stability
Solution Approach 1:
The patent combines the pitch angle adjustment mechanism and left-right angle adjustment mechanism into a single integrated structure. The sliding block moves along the inclined groove, where the groove's inclination converts horizontal sliding motion into coupled pitch and left-right angle adjustments. This merging eliminates mutual interference between independent mechanisms while maintaining adjustment independence through the wedge-shaped geometric relationship.
Solution Approach 2:
The inclined groove acts as an intermediary element that mediates between the adjustment screw's linear motion and the LED light source's angular adjustments. By introducing this intermediate geometric structure, the system achieves coupled pitch and left-right angle adjustments without direct mechanical interference between the two adjustment functions.
2Adaptability or versatility
If multiple independent adjustment mechanisms are used, then comprehensive adjustment coverage is achieved, but the structure becomes complicated and costs increase
Solution Approach 1:
The patent merges multiple adjustment functions into a single integrated mechanism. The sliding block with inclined groove simultaneously provides pitch angle adjustment and left-right angle adjustment through one coordinated motion, eliminating the need for separate mechanisms and reducing overall structural complexity.
Solution Approach 2:
The sliding block serves multiple functions: it acts as the adjustment carrier, provides the inclined groove for motion conversion, and houses the reset spring mechanism. This multi-functionality reduces the number of separate components needed while maintaining comprehensive adjustment coverage.
3Ease of operation
If traditional adjustment mechanisms are used, then adjustment function is achieved, but the structure is bulky and not compact
Solution Approach 1:
The patent employs a nested structure where the sliding block is positioned within the housing, the LED light source is mounted on the sliding block, and the reset spring is housed within the sliding block's internal cavity. This nesting arrangement minimizes the overall volume of the adjustment mechanism while maintaining full adjustment functionality.
