Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing force detection systems, like those described in PTL 1, only detect the force applied to operation tools, which is insufficient for digitalizing the skills of delicate work, such as cell culture operations, as they do not capture the precise angles and forces required for proper bodily movement.
Innovation Solution
A digitalization system comprising a first sensor to detect deformation of the work tool, a second sensor to detect force applied to or from the work tool, and a computer that calculates the angle formed with the work target and the force applied, enabling the digitalization of delicate work skills by analyzing these parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only force detection is implemented, then the device complexity is reduced, but the measurement precision is insufficient for digitalizing delicate work skills
Solution Approach 1:
The system segments the measurement task into two distinct sensor functions: a first sensor mounted on the work tool to detect tool deformation, and a second sensor to detect force applied to the work target. This segmentation allows each sensor to specialize in one type of measurement, improving overall measurement precision while keeping individual sensor complexity manageable
Solution Approach 2:
The system merges data from two different sensors (deformation detection and force detection) through a computer that integrates both measurement streams. This combination provides comprehensive digitalization of delicate work skills by capturing both the tool's state and the applied force, achieving high measurement precision without requiring a single overly complex sensor system
2Loss of information
If sensors are added to detect deformation and force, then the digitalization capability is improved, but the device complexity increases
Solution Approach 1:
The system divides the information collection task into two specialized sensors: one for deformation and one for force. This segmentation ensures that each sensor captures its specific type of information accurately, reducing information loss about the delicate work process while avoiding the need for a single complex multi-functional sensor
Solution Approach 2:
The computer processes and integrates data from both sensors, creating a comprehensive digital representation of the work process. This feedback mechanism ensures that no critical information is lost by properly combining deformation and force measurements, while the modular architecture keeps device complexity manageable
