Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rehabilitation exercises require frequent visits to hospitals or rehabilitation centers, which can be inconvenient and lead to abandonment due to mobility issues or long-term requirements, and there is a lack of infrastructure for providing continuous rehabilitation guidance.
Innovation Solution
An exercise rehabilitation system using a smart mirror with integrated AI coaching, 3D imaging, and real-time feedback to facilitate rehabilitation exercises anywhere, including a smart mirror device with a display panel, touch panel, half mirror, and AI modules for motion tracking and evaluation, enabling continuous rehabilitation guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rehabilitation exercises are conducted with therapist assistance in hospitals, then rehabilitation quality and guidance accuracy are improved, but patient mobility freedom and accessibility are reduced
Solution Approach 1:
The system enables patients to perform rehabilitation exercises independently at home using the smart mirror device. The AI coaching module provides automated guidance and correction, replacing the need for constant therapist presence while maintaining rehabilitation quality through real-time motion analysis and feedback.
Solution Approach 2:
The smart mirror system acts as an intermediary between the patient and the rehabilitation therapist. It captures motion data via cameras, analyzes it through AI algorithms, and provides feedback that would otherwise require direct therapist intervention, thereby bridging the gap between home-based convenience and clinical-quality guidance.
2Reliability
If patients visit rehabilitation centers frequently for long-term rehabilitation, then rehabilitation effectiveness is improved, but patient time consumption and travel burden increase
Solution Approach 1:
The system pre-stores comprehensive rehabilitation exercise programs and coaching content in its database. Patients can access these pre-prepared programs at any time without needing to schedule appointments or travel to rehabilitation centers, eliminating time consumption while maintaining rehabilitation effectiveness through structured, evidence-based exercise protocols.
Solution Approach 2:
The smart mirror system enables continuous rehabilitation exercises to be performed at home without interruption. Patients can exercise whenever convenient, accumulating training volume consistently over time without the breaks and travel time associated with center-based programs, thereby maintaining effectiveness while reducing time loss.
3Adaptability or versatility
If smart mirror device with multiple functional modules is implemented, then rehabilitation guidance capability and user experience are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The system combines multiple functional modules including display panel, touch panel, half mirror, cameras, speakers, and AI processing into a single integrated smart mirror device. This merging approach enables comprehensive rehabilitation guidance capabilities while managing device complexity through unified architecture and shared components.
Solution Approach 2:
The smart mirror device is designed as a multi-functional platform that can support various rehabilitation exercises, provide visual and audio feedback, track multiple body joints, and adapt to different user levels. This universality allows a single device to deliver comprehensive rehabilitation guidance without requiring multiple specialized pieces of equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables continuous rehabilitation exercises at any time and location, providing personalized and effective guidance through real-time feedback and AI-driven coaching, maximizing rehabilitation effectiveness without direct therapist assistance.
Implementation Method 1
a time of flight (TOF)/stereo camera that generates a 3D image by imaging a user present in front of the smart mirror device
Implementation Method 2
a half mirror attached to a front surface of the touch panel to allow the user to view a rehabilitation exercise of the user with naked eyes
