Solution Overview
Problem
Current medical devices for standing aid are cumbersome and lack the ability to adjust training intensity based on the user's condition, making it difficult for patients to understand their rehabilitation progress and adjust their training effectively.
Innovation Solution
A medical apparatus featuring a crank rocker mechanism with a triangular linkage mechanism that assists users in standing by providing oblique support, combined with a data processing system for real-time adjustment of training programs based on user data and machine learning algorithms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a crank rocker mechanism with triangular linkage is used to provide ergonomic support, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The support mechanism is divided into multiple functional components: crank mechanism, triangular linkage mechanism, and rocker mechanism. Each segment performs a specific function in the sequence of converting rotational motion to oscillating support motion, making the complex device more manageable and maintainable while achieving ergonomic movement patterns
Solution Approach 2:
The mechanism uses dynamic motion patterns where the triangular linkage continuously changes its geometric configuration during operation. The crank rotates continuously while the rocker oscillates back and forth, creating a dynamic system that adapts to the user's movement needs throughout the exercise cycle
2Adaptability or versatility
If data processing and machine learning systems are integrated for real-time training adjustment, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The system incorporates sensors that continuously monitor exercise data and feed this information to a processing system. The processed data triggers feedback signals that automatically adjust training parameters in real-time, creating a closed-loop control system that adapts to user performance without requiring complex manual intervention
Solution Approach 2:
The machine learning system automatically analyzes exercise data and adjusts training programs without external intervention. The system serves itself by making real-time decisions about parameter adjustments based on processed sensor data, reducing the need for complex user input or manual programming
