Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile examination technologies fail to accurately deduce the force applied to a target object due to neglecting the orientation of the pressure sensor and the characteristics of the worker's hand, resulting in low accuracy in reaction deduction.
Innovation Solution
A contact information obtaining apparatus that uses pressure data from a pressure sensor, direction data from a direction sensor, and hand characteristic data to deduce the applied-pressure direction and calculate the reaction of the target object, incorporating a determination unit to assess if the reaction is within a reference range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure data alone is used to deduce force applied to target object, then measurement simplicity is maintained, but deduction accuracy deteriorates due to neglecting pressure sensor orientation and hand characteristics
Solution Approach 1:
The patent combines pressure data from the pressure sensor with direction data from the direction sensor and characteristic data about hand geometry to comprehensively deduce the applied-pressure direction. This merging of multiple data sources resolves the contradiction by improving deduction accuracy through integrated information while managing system complexity through coordinated sensor operation.
Solution Approach 2:
The patent introduces characteristic data about hand geometry as an intermediary element that mediates between the raw pressure data and the final force deduction. This intermediary allows the system to account for hand characteristics without requiring direct complex measurements, thereby improving accuracy while controlling complexity.
2Measurement precision
If pressure sensor orientation and hand characteristics are considered in force deduction, then deduction accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-storing characteristic data about hand geometry and using it to establish the relationship between pressure sensor orientation and applied-pressure direction before actual measurement. This preliminary preparation enables more accurate real-time deductions without increasing the complexity of moment-to-moment data processing.
Solution Approach 2:
The patent implements feedback by using the deduced applied-pressure direction to calculate the applied-pressure reaction and determine whether it falls within reference ranges. This feedback mechanism improves reaction deduction accuracy by iteratively refining the force analysis based on multiple measured parameters while maintaining manageable processing complexity through structured calculation steps.
3Measurement precision
If multiple sensors and data types are integrated for accurate force deduction, then measurement precision is improved, but system complexity increases
Solution Approach 1:
The patent applies universality by using a integrated sensor system where the pressure sensor and direction sensor work together to serve multiple measurement functions simultaneously. This multi-functionality approach improves force measurement accuracy by capturing both magnitude and direction of applied pressure with a coordinated sensor system rather than requiring separate specialized devices for each measurement type.

AI summary
A contact information obtaining apparatus (100) includes an applied-pressure direction deducing unit (110), a reaction calculation unit (120), and a determination unit (130). The applied-pressure direction deducing unit (110), using pressure data that a pressure sensor that measures pressure that a worker is applying to a target object by a hand of the worker measured, direction data that a direction sensor that measures a direction concerning the hand measured, and characteristic data that indicates a characteristic of the hand, deduces an applied-pressure direction that is a direction of the pressure that the hand is applying to the target object and a direction relative to the target object. The reaction calculation unit (120), using the pressure data and the applied-pressure direction that is deduced, calculates an applied-pressure reaction that is a reaction of the target object to the hand applying force to the target object. The determination unit (130) determines whether or not the applied-pressure reaction is within a reference range.
