Movement Assistance Force Control for Posture-Stable Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing movement assistance devices only indicate the traveling direction of users without considering safe guidance.
Innovation Solution
A movement assistance device and method that apply an assisting force, which is a resultant force of a virtual force for stabilizing the user's posture and a guiding force for guiding the user, to the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only traveling direction indication is provided to the user, then the device complexity is reduced, but the safety and reliability of user guidance deteriorates
Solution Approach 1:
The assisting force is segmented into two distinct functional components: virtual force (for posture stabilization) and guiding force (for directional guidance). This segmentation allows the system to address multiple safety requirements simultaneously while maintaining manageable system complexity through modular force control
Solution Approach 2:
The movement assistance device applies a unified assisting force that simultaneously performs multiple functions: stabilizing user posture and guiding traveling direction. This multi-functionality resolves the contradiction by providing comprehensive safety guidance without requiring separate independent systems
2Reliability
If a resultant force of virtual force and guiding force is applied to the user, then the reliability of safe guidance is improved, but the device complexity increases
Solution Approach 1:
The virtual force and guiding force are merged into a single resultant assisting force applied to the user. This combining approach improves reliability by providing comprehensive safety guidance while avoiding the complexity of multiple separate force application systems by unified control
