Endoscope Tracker Quick-Connect for Precise Motion Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope devices suffer from inaccuracies in motion capture due to play in adapters, requiring continuous recalibration and lacking precise positioning and orientation of tracker modules, which affects user-friendliness and patient safety.
Innovation Solution
An endoscope device with a quick-connect interface that defines the position and orientation of a tracker module relative to the endoscope camera, storing factory-determined parameters on a storage medium, and incorporating a control unit for simplified calibration and component verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple adapter is used to mount the tracker module, then assembly is easy, but positioning precision and orientation accuracy deteriorate
Solution Approach 1:
The adapter is divided into separate functional elements: a connection element for easy attachment and a positioning element with factory-determined parameters for precise positioning. This segmentation allows each element to optimize its function independently.
Solution Approach 2:
The positioning parameters are determined and stored at the factory before use. This preliminary action eliminates the need for user calibration while ensuring consistent, accurate positioning every time the adapter is used.
2Measurement precision
If manual calibration is performed before each use, then positioning accuracy is maintained, but operation time and complexity increase
Solution Approach 1:
The calibration process is performed once at the factory, and the results are stored in the adapter. This eliminates the need for repeated manual calibration before each use, saving time while maintaining accuracy.
Solution Approach 2:
The adapter contains its own calibration data and automatically provides correct positioning without requiring user intervention. The system serves itself by using the pre-stored parameters to maintain accuracy throughout its operation.
3Adaptability or versatility
If the adapter allows detachable connection, then hygiene and reusability are improved, but connection stability and positioning consistency may deteriorate
Solution Approach 1:
The connection system is segmented into separate connector components that can be detached and sterilized independently. This allows the adapter to maintain reliability through secure connection while enabling hygiene requirements for multi-use devices.
Solution Approach 2:
The positioning parameters are pre-determined and locked into the adapter structure. This ensures that every time the detachable connector is assembled, the same precise positioning is automatically achieved without requiring realignment or recalibration.
