Shoe Insole with Pressure Switch and Vibration Motor for Toe Walking Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mild toe walking, often associated with conditions like cerebral palsy, is challenging to correct as existing methods fail to provide immediate and effective feedback to the user to adjust their gait, hindering muscle relaxation and movement precision.
Innovation Solution
An elongated shoe insole with a momentary electric switch and vibrator assembly that vibrates upon toe walking, providing immediate feedback to the user to correct their gait by connecting the switch, battery, and vibrator in series, allowing for corrective action through repetitive stimulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional passive insoles are used, then the device complexity is low, but the feedback immediacy and gait correction effectiveness are insufficient
Solution Approach 1:
The patent implements immediate tactile feedback by connecting a vibration motor to a pressure-sensitive switch on the insole. When the user walks on toes, pressure activates the switch, triggering the vibration motor to provide real-time corrective feedback, thereby improving gait correction effectiveness through active feedback loops rather than passive support
Solution Approach 2:
The system enables self-monitoring and self-correction by the user. The insole independently detects toe-walking through the pressure-sensitive switch and activates vibration feedback without external intervention, allowing the user to self-correct their gait pattern through the tactile alert, thus achieving effective correction with minimal external control
2Ease of operation
If no immediate feedback is provided, then the device complexity remains simple, but the user cannot及时调整 their gait pattern
Solution Approach 1:
The vibration motor provides immediate tactile feedback when the pressure-sensitive switch detects toe-walking pressure. This real-time alert enables the user to instantly recognize and correct their gait pattern, making gait adjustment intuitive and easy through sensory feedback rather than requiring complex cognitive monitoring or external supervision
3Reliability
If repetitive stimulation is not applied, then the device simplicity is maintained, but neuroplasticity enhancement and muscle retraining are hindered
Solution Approach 1:
The system delivers periodic vibration stimulation each time toe-walking occurs, as detected by the pressure-sensitive switch. This repetitive tactile feedback across multiple walking instances reinforces proper gait patterns through neuroplasticity, leveraging periodic corrective stimulation to retrain muscle memory and brain pathways without requiring complex programming or external intervention
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively reminds the user of toe walking, assisting in muscle relaxation and improving gait by providing immediate tactile feedback, which aids in retraining the brain through neuroplasticity enhancement.
Implementation Method 1
a momentary electric switch disposed proximate to the toe portion, the momentary electric switch being responsive to tip toe stepping
Implementation Method 2
a vibrator assembly disposed distal to the toe portion... causes the vibrator assembly to vibrate
