Balance Training Cart with Posture Detection and Dynamic Swing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing balance training apparatuses for rehabilitation struggle to adjust difficulty levels effectively based on individual trainees' physical abilities and recovery progress, leading to inconsistent training experiences.
Innovation Solution
A balance training apparatus equipped with a moving cart, posture detection sensors, and a difficulty level setting unit that adjusts the training difficulty by detecting the trainee's posture disturbances and changing the swing pattern of the cart, using sensors such as handrail sensors, pressure sensors, biological sensors, or cameras to provide tailored training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the footplate is moved by a small amount to maintain trainee stability, then safety is improved, but training motivation deteriorates due to lack of environmental change
Solution Approach 1:
The patent applies dynamics by making the cart movable along the moving surface instead of using a fixed footplate. The cart can be dynamically positioned at different locations (first, second, and third positions) to create varying training environments. This dynamic repositioning provides environmental change that boosts trainee motivation while maintaining safety through controlled movement ranges.
2Productivity
If the cart moves at high speed to increase training intensity, then rehabilitation effectiveness is improved, but safety deteriorates due to excessive disturbance
Solution Approach 1:
The patent implements feedback through posture detection sensors that continuously monitor the trainee's balance state. When the sensor detects that the trainee's posture disturbance exceeds a predetermined threshold, the system automatically adjusts the cart's movement speed or stops movement. This feedback mechanism ensures that high-speed movement that increases rehabilitation effectiveness does not compromise safety by exceeding the trainee's tolerance limits.
3Adaptability or versatility
If the training program is customized for each individual trainee, then rehabilitation effectiveness is improved, but system complexity increases due to multiple adjustment parameters
Solution Approach 1:
The patent applies parameter changes by adjusting key movement parameters (cart position, speed, and acceleration) based on detected trainee posture. The system modifies these parameters dynamically during training sessions to customize the program for each trainee's ability level and recovery progress. This approach enables effective customization without requiring overly complex control systems, as it focuses on adjusting a limited set of critical movement parameters.

AI summary
The balance training apparatus includes: a moving cart capable of moving on a moving surface by driving a driving unit; a movement controller configured to drive the driving unit and to move the moving cart in accordance with a predetermined swing pattern; a posture detection sensor that is provided in the moving cart and is configured to detect that disturbance of the state of a trainee who is standing on the moving cart has become outside of a predetermined range; and a difficulty level setting unit configured to instruct the movement controller to change the swing pattern and change the difficulty level of the training that moves the moving cart based on results of detecting the state of the trainee regarding which a notification is sent from the posture detection sensor.
