Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exercise devices are inadequate for users with insufficient muscle strength or bilateral coordination disorders, such as those with stroke or cerebral palsy, as they struggle to perform cyclic pedaling exercises due to insufficient muscle strength in one limb or coordination issues.
Innovation Solution
An exercise device with a base unit, training unit, detection unit, analyzing and processing module, and electrical auxiliary unit that assists users by detecting pedaling states and providing electrical assistance to complete pedaling cycles, ensuring continuous exercise and improved muscle strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional exercise devices are used, then users with sufficient muscle strength can perform cyclic pedaling exercise, but users with insufficient muscle strength or bilateral coordination disorders cannot complete the exercise
Solution Approach 1:
The patent introduces an electrical auxiliary unit as an intermediary between the user and the pedaling exercise. This unit detects the user's pedaling state through a detector and provides electrical assistance to the training unit when assistance is required, enabling users with insufficient muscle strength to complete the exercise cycle.
Solution Approach 2:
The patent implements a feedback mechanism where the detector continuously monitors the user's pedaling state and sends detection signals to the analyzing and processing module. The module determines whether assistance is required based on the detection signal and controls the electrical auxiliary unit accordingly, creating a closed-loop control system that adapts to user needs.
2Adaptability or versatility
If electrical auxiliary assistance is provided, then users with insufficient muscle strength can complete pedaling exercise, but the device complexity increases
Solution Approach 1:
The patent implements self-service functionality where the device automatically detects the user's pedaling state and determines when assistance is required without manual intervention. The analyzing and processing module autonomously processes detection signals and controls the electrical auxiliary unit, reducing the need for complex manual control mechanisms.
Solution Approach 2:
The patent replaces manual or mechanical resistance adjustment mechanisms with an electrical assistance system. Instead of requiring users to manually overcome resistance, the electrical auxiliary unit provides assisted torque through electrical motors, simplifying the user's physical effort while adding controlled electrical complexity to the system.

AI summary
An exercise device, endlessly pedaled by a user, includes a base unit, a training unit connected to the base unit, a detection unit arranged on the training unit, an analyzing and processing module coupled to the detection unit, and an electrical auxiliary unit coupled to the analyzing and processing module. The electrical auxiliary unit can assist in driving the training unit. The detection unit detects the usage state of the detection unit to generate a detection signal. When a user applies force to the training unit to exercise, the analyzing and processing module will determine that the assistance of external force is required according to the detection signal and transmit an electrical auxiliary signal to the electrical auxiliary unit if the exercise stagnates due to insufficient force. The electrical auxiliary unit assists in driving the training unit to help the user complete exercise according to the electrical auxiliary signal.
