Multi-Finger Force Sensor Processing for Finger Skill Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for measuring finger force are inadequate as they primarily focus on independent muscle strength of a thumb and a finger, failing to accurately measure the force of the finger.
Innovation Solution
An information processing apparatus equipped with two or more force sensors to detect the force of multiple fingers, along with a processing unit that processes these measurements to determine finger force, independence, agility, repetitive reproducibility, and temporal accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional techniques measure only independent muscle strength of thumb and finger, then the measurement system remains simple, but the measurement precision and comprehensiveness of finger force is insufficient
Solution Approach 1:
The measurement system is segmented into multiple independent force sensors, each dedicated to detecting force from a specific finger. This segmentation allows each sensor to specialize in measuring force from one finger, thereby improving measurement precision for each individual finger while maintaining a relatively simple overall system structure through modular design.
Solution Approach 2:
The force sensor system is designed with multi-functionality to measure forces from multiple fingers (thumb, index, middle, ring, and little fingers) simultaneously using a unified measurement platform. This universal approach enables comprehensive finger force measurement without requiring separate specialized devices for each finger, balancing measurement comprehensiveness with system simplicity.
2Adaptability or versatility
If multiple force sensors are used to detect forces of multiple fingers, then measurement comprehensiveness improves, but device complexity increases
Solution Approach 1:
Multiple force sensors are merged into a single integrated measurement system where all sensors work together on one unified platform. This combining approach allows the system to detect forces from multiple fingers simultaneously, achieving versatile multi-finger measurement capability while avoiding the complexity of multiple separate measurement systems through centralized integration.
