Light Touch Keeping Apparatus for Balance Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals performing difficult tasks, such as standing on unstable surfaces, often inadvertently apply a forceful touch, leading to loss of posture stability and erroneous control, as existing sensory feedback methods fail to maintain a light touch state effectively.
Innovation Solution
A light touch maintaining device comprising a contact load evaluation unit and an exercise intervention control unit that assesses and intervenes to maintain a light touch state by adjusting exercise intensity based on contact load and fall risk, using electrical stimulation to correct fingertip contact when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensory feedback is provided to maintain light touch state, then contact load control is improved, but the system fails when subject performs highly difficult tasks causing force touch
Solution Approach 1:
The system continuously monitors contact load between fingertip and support, providing real-time sensory feedback to the subject. When contact load exceeds the light touch threshold (1N), the system detects this state and provides corrective feedback, enabling the subject to maintain appropriate contact force during balance training tasks.
Solution Approach 2:
The system dynamically adjusts the feedback parameters based on the detected contact load. When a force touch state is detected (contact load > 1N), the system modifies the feedback intensity and type to guide the subject back to a light touch state, adapting the control parameters to the subject's current performance level.
2Productivity
If subject performs highly difficult balance tasks, then balance training effectiveness is improved, but light touch state cannot be maintained due to posture loss
Solution Approach 1:
The system introduces an intermediary feedback mechanism between the subject's natural balance control and the support surface. This feedback mediator provides real-time information about contact load, enabling the subject to adjust their posture and maintain light touch state even during challenging balance tasks that would otherwise cause posture loss.
Solution Approach 2:
The system provides preliminary feedback before the subject completely loses posture control. By continuously monitoring contact load and providing early warning feedback when approaching force touch state, the system enables preventive posture adjustments, maintaining light touch state before complete posture loss occurs.

AI summary
A light touch maintaining device includes: a contact load evaluation unit that determines whether a subject person is in a light touch state, on the basis of a contact load between the subject person and a support; and an exercise intervention control unit that controls exercise intervention on the subject person, to maintain a light touch state when the subject person is not in a light touch state.
