Solution Overview
Problem
Current rehabilitation training apparatuses for arm disabilities lack direct sensory experience and uniformity, as they are primarily wearable devices, and rehabilitation training results are subjective and difficult to standardize.
Innovation Solution
A to-be-detected unit with a cylindrical body, electrodes, and guides that can be stacked and connected electrically, combined with a control board for insertion detection and position determination, allowing for objective measurement and customized training.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable rehabilitation training apparatuses are used, then the apparatus can be worn on the body, but direct sensory experience such as touch and proprioception cannot be directly recognized through the fingers
Solution Approach 1:
The patent introduces an intermediary detection system consisting of electrodes and control boards that mediate between the user's finger interactions with the to-be-detected unit and the rehabilitation training system. The electrodes detect electrical signals from finger contact, providing indirect but measurable sensory data without requiring direct wearable sensors on the fingers.
Solution Approach 2:
The patent replaces mechanical wearable sensors with an electrical detection system. Instead of using mechanical pressure sensors or accelerometers in wearable devices, the system uses electrical conductivity detection through electrodes to sense finger interactions, substituting mechanical measurement with electrical field-based detection.
2Adaptability or versatility
If therapists conduct rehabilitation training manually, then personalized training can be provided, but uniform rehabilitation training is difficult due to different therapist standards
Solution Approach 1:
The patent implements an automated feedback system where the control board detects which to-be-detected units are inserted in which insertion portions, and provides feedback through lights or sounds. This automated feedback mechanism ensures uniform training standards while allowing personalized training programs to be designed by therapists, resolving the contradiction between customization and standardization.
Solution Approach 2:
The system enables self-service rehabilitation training where users can independently complete training exercises by inserting to-be-detected units according to instructions. The automated detection and feedback systems guide users through the training process without requiring constant therapist intervention, ensuring uniform execution of training protocols while maintaining adaptability through programmable training programs.
3Adaptability or versatility
If multiple to-be-detected units are stacked and connected, then the device complexity increases, but electrical connection between units must be ensured
Solution Approach 1:
The patent divides the rehabilitation training system into segmented to-be-detected units that can be individually stacked and connected. Each unit contains its own electrodes and can function independently or in combination with other units, allowing flexible configuration while simplifying electrical connection management through modular design.
Solution Approach 2:
The to-be-detected units are designed with universal interfaces that allow them to be stacked and connected in various configurations. The electrodes and connection structures are standardized across all units, enabling multi-functional use where the same unit type can serve different training purposes when stacked in different arrangements, reducing overall system complexity.

AI summary
Provided are a to-be-detected unit for rehabilitation training and a rehabilitation training system. The to-be-detected unit for rehabilitation training comprises: a cylinder-shaped main body with an opening in at least one side thereof; a first electrode portion formed on one region of the circumference of the main body; a second electrode portion separated from the first electrode portion and formed on another region of the circumference of the main body; and a guide portion which is formed between the first electrode portion and the second electrode portion to block the electrical connection between the first electrode portion and the second electrode portion, and which is recessed or protrudes at the circumference of the main body to a predetermined depth.
