Integrated Four-Axis Positioning Platform for Compact Optics Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current four-axis positioning platforms for optic systems in the defense industry are costly, complex, and lack a compact structure due to separate components connected to achieve motion on four axes, limiting their functionality and ease of use.
Innovation Solution
A single, non-compact positioning platform with an upper and lower plate connected by adjustment members, connection members, fixing members, and a yaw screw mechanism that allows for movements such as pitching, rolling, and raising on a unified platform, enabling four-axis positioning without the need for multiple separate platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate platforms are connected to achieve four-axis positioning, then positioning functionality is provided, but cost increases and compact structure cannot be obtained
Solution Approach 1:
The patent merges multiple separate positioning platforms into a single integrated platform structure. The upper plate and lower plate are connected through adjustment members to form a unified four-axis positioning system, eliminating the need for multiple separate platforms while maintaining all positioning functionalities (pitching, rolling, diving, and raising movements).
Solution Approach 2:
The single platform structure is designed to perform multiple functions simultaneously - it provides all four-axis positioning movements (pitching via first adjustment member, rolling via second adjustment member, diving via third adjustment member, and raising via yaw screw) within one integrated system, making the structure universal and multi-functional.
2Adaptability or versatility
If multiple separate platforms are connected to achieve four-axis positioning, then positioning functionality is provided, but cost increases
Solution Approach 1:
The patent combines multiple separate platforms into one integrated platform, reducing the total number of components that need to be manufactured and assembled. This merging approach eliminates redundant structures and reduces overall manufacturing costs while maintaining four-axis positioning capabilities.
Solution Approach 2:
The single platform is designed as a universal structure that performs all four-axis positioning functions, eliminating the need to manufacture and purchase multiple separate platforms. This multi-functional design reduces material costs, manufacturing expenses, and assembly complexity.
3Adaptability or versatility
If adjustment members connect upper and lower plates, then four-axis positioning is achieved, but structure becomes complex
Solution Approach 1:
The patent segments the positioning functions into distinct adjustment members, each responsible for specific movements (first adjustment member for pitching, second for rolling, third for diving, yaw screw for raising). This segmentation allows complex movements to be achieved through simple, dedicated components rather than a monolithic complex structure.
Solution Approach 2:
The adjustment members are designed with dynamic capabilities - they can be adjusted and repositioned to provide different movement axes. The slot fixing members with slots allow for adjustable positioning, and the spring mechanisms provide dynamic compensation, making the structure adaptable without being overly complex.
