Lower Limb Rehabilitation Device with Multi-Angle Camera System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing neuromotor rehabilitation devices for lower limbs are not effective due to limited visualization of movements, require lengthy setup adjustments for each patient, and are not adaptable to individual morphologies, reducing treatment efficacy.
Innovation Solution
A device with central and lateral cameras and screens providing a comprehensive view of lower limb movements, adjustable structure for patient comfort and morphology, and a versatile platform with haptic and visual effects, allowing for efficient setup and use in various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single central camera and screen are used for mirror therapy, then the device is simple, but the visualization of lower limb movements is insufficient
Solution Approach 1:
The device is divided into multiple independent camera-screen units: a central unit for the patient's direct view and lateral units for additional perspectives. Each unit captures and displays movements independently, providing comprehensive visualization without requiring a single complex system.
Solution Approach 2:
The invention adds lateral cameras and screens positioned at the sides of the patient, introducing a new spatial dimension for viewing movements. This complements the central front-facing view by providing side perspectives that reveal movement ranges invisible from the front alone.
2Adaptability or versatility
If the device is fixed in position, then the structure is simple, but it cannot adapt to different patient morphologies
Solution Approach 1:
The device incorporates height-adjustable components including the camera mounting structure and screen position. These dynamic elements can be adjusted vertically to accommodate patients of different heights and morphologies, transforming a static fixed-position device into an adaptable system.
Solution Approach 2:
The adjustable height mechanism allows the same device configuration to serve multiple patient types and treatment positions (sitting or standing). The universal adjustment capability eliminates the need for multiple fixed devices tailored to specific patient groups.
3Adaptability or versatility
If the device requires extensive adjustment for each patient, then individualization is achieved, but treatment time is reduced
Solution Approach 1:
The device provides preliminary adjustment through height-adjustable components that can be quickly configured before each session. This preliminary setup reduces the time required for detailed individualization during treatment, allowing rapid adaptation to different patients while maintaining personalized therapy.
Solution Approach 2:
The practitioner can independently adjust the device height and position without requiring complex calibration or assistance. This self-service capability enables quick individualization for each patient, reducing setup time while maintaining treatment personalization.
4Loss of information
If only a central viewpoint is provided, then the device is simple, but the full range of movements cannot be perceived
Solution Approach 1:
The camera system is segmented into multiple units positioned at different locations: central cameras for front views and lateral cameras for side views. Each camera captures a specific portion of the movement, and together they provide complete coverage of the full movement range.
Solution Approach 2:
By adding lateral cameras positioned at the sides of the patient, the system captures movements in additional spatial dimensions. This reveals the full range of motion including dorsiflexion and plantarflexion that are invisible from a purely central front-facing perspective.

AI summary
A device for implementing a mental representation technique for the rehabilitation of at least one lower limb, in front of which a patient is intended to be positioned, includes a central camera arranged to film the lower limb from a central viewpoint and a central display screen arranged to hide the patient's direct view of the lower limb, and intended to display the viewpoint filmed by the central camera. The device also includes at least one lateral camera arranged to film the lower limb from a lateral perspective, and a lateral display screen intended to display the viewpoint filmed by the lateral camera.
