3D Imaging Module Assembly for Stable Scanner Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional scanners experience precision drift due to unstable module connections, requiring frequent calibrations and increasing usage costs.
Innovation Solution
Integrate camera modules and lens groups within accommodating cavities in a lens mount, reducing gaps and external forces, and incorporate a light source within the module to enhance stability and reduce calibration frequency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple modules are fixed by being mounted on a single base or connected sequentially, then the device can be assembled and operated, but the connection stability is poor leading to precision drift
Solution Approach 1:
The patent merges multiple modules (camera module, light source module, lens group) into a single integrated imaging module that is mounted on the base as one unit. This combination eliminates the need for multiple separate connections, thereby improving connection stability and preventing precision drift over time.
Solution Approach 2:
The patent segments the imaging system into distinct functional modules (camera module, light source module, lens group) that are integrated together, allowing each module to be independently optimized while maintaining stable relative positions through the unified mounting structure.
2Productivity
If modules are connected sequentially or mounted on a single base, then the device can function, but frequent calibration is required increasing usage time and costs
Solution Approach 1:
By combining multiple modules into one integrated unit with stable internal connections, the patent reduces the frequency of calibration needed, thereby decreasing time loss and improving overall usage efficiency.
3Ease of manufacture
If multiple modules are separately mounted and connected, then the device can be assembled, but the structure is complex and assembly is difficult
Solution Approach 1:
The patent combines multiple separately mounted modules into a single integrated imaging module, simplifying the overall structure and reducing assembly complexity. The integrated design allows for easier manufacturing and installation while maintaining all necessary functional connections internally.
