Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional scanners face precision drift issues due to detachable 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 for stable light emission and reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If multiple modules are fixed by being mounted on a single base or connected sequentially, then the device can be assembled and disassembled for maintenance, but the connection stability deteriorates and precision drifts over time
Solution Approach 1:
The patent merges multiple modules (camera module, lens group, light source) into a single integrated three-dimensional imaging module. This integration eliminates the connections between separate modules, thereby eliminating the precision drift caused by connection instability while maintaining the ability to replace the entire module for maintenance.
2Ease of manufacture
If detachable connection methods are used for multiple modules, then assembly and disassembly is facilitated, but structural stability deteriorates and calibration frequency increases
Solution Approach 1:
The patent combines multiple functional modules into a single integrated unit with a unified housing structure. This merging eliminates the detachable connections between modules, thereby improving structural stability and reducing calibration frequency while simplifying the assembly process to a single module installation.
3Measurement precision
If frequent calibration is performed to maintain precision, then measurement accuracy is maintained, but usage efficiency decreases and costs increase
Solution Approach 1:
The patent integrates all critical components (camera, lens, light source) into a single module with fixed relative positions, eliminating the precision drift caused by detachable connections. This integration reduces calibration frequency, thereby improving usage efficiency and reducing costs while maintaining measurement precision.
