Triangular Prism Physical Therapy Device with Visual Positioning Aids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current physical therapy devices lack the ability to consistently and correctly guide patients in stretching and exercising their lower extremities without the supervision of a physical therapist, leading to potential incorrect execution of exercises.
Innovation Solution
A triangular prism-shaped physical therapy device with a heel positioning recess and leg positioning surface, featuring visual aids such as color and texture indicators to help patients correctly position their lower extremities for exercises, ensuring consistent and correct execution of stretches and exercises.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical therapy device is provided without supervision, then patient independence and convenience are improved, but the risk of incorrect exercise execution increases
Solution Approach 1:
The device incorporates visual aids including color-coded indicators and textured surfaces that change or differentiate to guide patients on correct positioning. Different colors and textures indicate different positioning requirements, enabling patients to independently perform exercises correctly without supervision.
Solution Approach 2:
The device serves as an intermediary between the physical therapist's instructions and the patient's exercise execution. By embedding positioning guides and visual aids directly into the device structure, it mediates the transmission of therapeutic instructions, ensuring accurate exercise performance without continuous professional supervision.
2Reliability
If visual aids are added to guide patient positioning, then exercise execution accuracy is improved, but device complexity increases
Solution Approach 1:
Instead of making the entire device complex, visual aids are applied locally at specific positioning areas. Different regions of the device have different textures, colors, or patterns only where needed to guide specific body parts, maintaining overall device simplicity while providing targeted guidance.
Solution Approach 2:
The device employs asymmetric visual patterns and non-uniform textures that naturally guide positioning through their inherent design. The asymmetric arrangement of visual aids creates intuitive directional cues that simplify the guiding function without requiring complex mechanical or electronic systems.

AI summary
A therapeutic system may include a triangular prism-shaped body, the triangular prism-shaped body including a first rectangle plane; a second triangular plane placed at a 90° angle relative to a first side of the first plane; a third plane rectangular placed at a 30° angle relative to a second side of the first plane; a fourth triangular plane placed at a 90° angle relative to a third side of the first plan; and a fifth rectangular plane place at a 60° angle relative to a fourth side of the first plane; a heel placement depression formed in the first rectangle plane; and a foot placement identifier formed on the third rectangular plane originating at the joint of the first rectangular plane and third rectangular plane and extending into the third rectangular plane.
