Height-Adjustable Physiotherapy Device with Constant Axis Distance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing physiotherapeutic devices lack variability and ease of use, particularly in adjusting training positions and operating mechanisms, which limits their effectiveness in rehabilitation for diverse patient needs and user operations.
Innovation Solution
A physiotherapeutic device with height-adjustable arm and leg trainers maintaining a constant distance between axes, allowing for both sitting and lying positions, combined with a pivoting display and color-coded control elements for easy operation, and motorized trainers moving at 90 revolutions per minute to treat Parkinson's disease.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the height of the arm and leg trainers is adjusted to provide variability in training positions, then the adaptability of the device is improved, but the structural complexity increases
Solution Approach 1:
The height adjustment mechanism is divided into two independent elements: a first element for clamping the foot element to the body element, and a second element for locking the foot element to the body element. This segmentation allows each element to perform a specific function, simplifying the overall mechanism while providing versatile height adjustment capabilities for different training positions.
2Ease of operation
If a single control element is used for height adjustment, then the ease of operation is improved, but the reliability decreases
Solution Approach 1:
The control system is segmented into two independent elements: a first control element for clamping and a second control element for locking. This segmentation ensures that releasing one element does not cause the device to collapse, as the other element maintains structural integrity. The step-by-step locking mechanism provides secure grip during operation while maintaining simple operation.
3Ease of operation
If the display is made fixed for stable viewing, then the ease of operation is improved, but the adaptability decreases
Solution Approach 1:
The display is designed to be pivotable relative to the longitudinal axis of the device. This dynamic feature allows the display to be adjusted to optimal viewing angles during operation, and can be swiveled during transport to reduce the device's footprint, creating a compact configuration for easy transportation while maintaining ease of use during therapy sessions.
