Solution Overview
Problem
Existing training devices for coordinative faculties lack the ability to automatically adjust the difficulty level based on individual performance, leading to either boring or demotivating exercises, especially when used with animals where feedback is impossible.
Innovation Solution
A device with a movable standing plate, static base plate, and adjustable connecting elements, along with a user interface and control element, that specifies setpoint positions for the user's center of gravity and continuously measures and compares actual positions to generate control signals, allowing for automatic adjustment of the training difficulty.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the degree of difficulty is adjusted manually by the user, then the training apparatus can accommodate different skill levels, but the user may choose an incorrect difficulty level leading to boredom or demotivation
Solution Approach 1:
The control element continuously measures the actual position of the user's center of gravity and compares it with the setpoint position, then generates control signals to adjust the connecting elements. This closed-loop feedback system automatically adapts the training difficulty based on real-time performance data, eliminating the need for manual difficulty selection and providing objective, continuous adjustment.
Solution Approach 2:
The training apparatus performs self-adjustment of the difficulty level by automatically measuring user performance and modifying the connecting element heights accordingly. The system serves itself by using its own measurement capabilities to control its operational parameters, removing the burden of manual adjustment from the user.
2Device complexity
If the training difficulty is kept constant, then the device structure remains simple, but the training becomes boring when the user improves or demotivating when the user struggles
Solution Approach 1:
The connecting elements are designed with adjustable heights that can be dynamically modified during operation. The control element continuously adjusts the connecting element heights based on real-time measurement of the user's center of gravity position, transforming a static structure into a dynamic system that adapts to user performance changes.
Solution Approach 2:
The system changes the physical parameter of the connecting element heights in response to measured performance. By continuously modifying this geometric parameter based on the user's actual center of gravity position relative to the setpoint, the system dynamically adjusts the mechanical advantage and stability characteristics of the training apparatus.
3Device complexity
If manual adjustment of connecting element height is required, then the device can be mechanically simple, but the user cannot detect improved performance and must actively adapt the difficulty
Solution Approach 1:
The control element continuously measures the actual position of the user's center of gravity and compares it with the setpoint position, providing real-time performance feedback. This information is used to automatically generate control signals that adjust the connecting elements, creating a closed-loop system where performance data drives system adaptation without requiring user interpretation or manual adjustment.

AI summary
The invention relates to a device for training coordinative faculties. The device has at least one movable standing plate; at least one static base plate; at least two connecting elements, the height of which can be modified and which act between the at least one movable standing plate and the at least one static base plate, a user interface; and a control element. The device is designed to specify a sequence of various setpoint positions of the centre of gravity of a user standing on the at least one movable standing plate, each of the setpoint positions being specified for a determined duration, and to continuously measure the actual position of the centre of gravity of the person standing on the moving plate. The device is further designed to compare each measured actual position to the setpoint position specified at the time of the measurement, to generate control signals taking into consideration the measured actual positions and/or the results of the comparisons of actual positions and setpoint positions, and to control the at least two connecting elements with the control signals.
