Wearable Exoskeleton Display for Real-Time COM Gait Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exoskeleton systems for gait training lack real-time, continuous visual feedback that does not disrupt patient exercise or therapist assistance, with current solutions either limiting information access or obstructing optimal viewing for both parties.
Innovation Solution
A removably attached terminal display that provides real-time visual feedback of the user's center of mass relative to their feet, wirelessly connected to the exoskeleton system, allowing clinicians and patients to access essential device information without disruption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a watch display is used to provide visual feedback, then the patient can directly view the information, but the patient must stop movement and rely on a single crutch to raise the arm, disrupting the flow of movement and introducing balance complications
Solution Approach 1:
The patent introduces a therapist-worn display device as an intermediary that relays visual feedback information from the exoskeleton system to the patient. Instead of requiring the patient to directly access a watch or separate device, the therapist acts as the intermediary who can view the information on their own display while supporting the patient, thereby maintaining patient balance and continuous movement flow.
2Loss of information
If a separate device like a tablet or laptop is used to provide visual feedback, then comprehensive information can be displayed, but the therapist must divert attention and physically approach the device to view it, preventing simultaneous observation of both the device and patient
Solution Approach 1:
The patent makes the therapist's wearable display device multi-functional: it serves both as a support tool for the patient (since the therapist wears it) and as a comprehensive information display (showing exoskeleton status, patient metrics, and therapeutic parameters). This eliminates the need for separate tablets or laptops, allowing the therapist to monitor all information while maintaining continuous patient contact.
3Device complexity
If a cabled touch-screen controller is attached to the exoskeleton, then a more integrated feedback solution is provided, but therapists observing from different points find their view obstructed and patients lose the ability to view the screen during operation
Solution Approach 1:
The patent transitions from a static, fixed-position display (cabled touch-screen attached to the exoskeleton) to a dynamic, mobile display solution. The therapist-worn display can be positioned anywhere within the therapist's field of view, adapting to different observation angles and patient positions. This dynamic positioning maintains system integration while providing universal viewing accessibility.
4Weight of moving object
If the watch screen size is small, then the device is compact and wearable, but it provides only a cursory overview with limited insights into additional settings and comprehensive visual feedback
Solution Approach 1:
The patent merges the functionality of multiple devices into a single therapist-worn display: the comprehensive information display capabilities of a tablet or laptop are combined with the portability and wearability of a watch or mobile device. The therapist wears a compact display that can show detailed exoskeleton settings, patient metrics, and therapeutic parameters, eliminating the information limitations of small screens while maintaining portability.

AI summary
A terminal display for a walking assistance system can be removably attached to the system. The system comprises can include segments including lumbar, thigh, shank, and optionally, foot segments. The system integrates multiple sensors to determine each segment's relative position and a control unit to process the user center of mass (COM) relative to their feet position. The display connects wirelessly to the control unit and presents the user's center of mass, preferably relative to their feet position, which is also displayed, enhancing this way walking assistance capabilities.
