Clamping Force Measurement with Contact Distance Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for influencing body tissue lack objective assessment capabilities during force application, relying on subjective patient feedback and failing to provide reliable data on tissue tolerance to different forces, especially in pathological or scar tissue conditions.
Innovation Solution
Incorporating a second measuring device to detect the distance between contacts, which interacts with a display device to track and evaluate changes in clamping force values over time, allowing for an objective assessment of tissue condition and creating databases for body tissue reactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only clamping force values are monitored with a first measuring device, then the device structure remains simple, but objective assessment of tissue condition is not possible and treatment reliability is reduced
Solution Approach 1:
The patent implements feedback by adding a second measuring device that detects distance between contacts and provides this information to the display device. This creates a feedback loop where both force magnitude and tissue deformation are monitored, enabling objective assessment of tissue condition and treatment effectiveness, thereby resolving the contradiction between reliability improvement and device complexity.
2Measurement precision
If subjective patient feedback is used to control clamping force, then the device operation remains simple, but measurement precision and treatment reliability are reduced
Solution Approach 1:
The patent replaces the subjective mechanical assessment method with an objective electronic measurement system. The second measuring device objectively detects distance between contacts, and the display device presents this data, substituting subjective patient feedback with precise electronic measurement, thereby improving measurement precision while maintaining ease of operation through automated data collection.
3Loss of information
If no distance measurement is provided, then the device structure remains simple, but loss of information about tissue deformation occurs
Solution Approach 1:
The second measuring device serves multiple functions: it detects distance between contacts, provides information about tissue deformation, and enables objective assessment when combined with force data. This multi-functionality approach reduces information loss while minimizing the increase in device complexity by using a single integrated measuring system.
