Multi-Mode Exoskeleton for Space Mission Training
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current exercise technologies for long-duration space missions are inadequate as they consist of multiple machines with limited capabilities, failing to effectively prevent muscle and bone atrophy caused by reduced gravity and lack comprehensive solutions for training, maintenance, and physical fitness.
Innovation Solution
An exoskeleton system with a control system that operates in multiple preconfigured modes, including activity simulation, strength enhancement, and low or zero gravity simulation, integrated with virtual reality and actuators for immersive and multi-purpose use, providing resistance and feedback to users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate exercise machines are used, then comprehensive training capabilities are achieved, but system complexity and volume increase
Solution Approach 1:
The patent combines multiple exercise machines (treadmill, stationary bike, resistance machine) into a single exoskeleton system that can perform walking, cycling, and strength training functions. The control system integrates multiple operating modes (strength enhancement, activity simulation, low gravity simulation) into one device, reducing system complexity while maintaining comprehensive training capabilities
Solution Approach 2:
The exoskeleton system is designed as a universal training device that can perform multiple exercise functions simultaneously or separately. The same hardware platform supports strength enhancement mode, activity simulation mode, and low gravity simulation mode, allowing one device to replace multiple specialized machines
2Adaptability or versatility
If multiple separate exercise machines are used, then comprehensive training capabilities are achieved, but system volume increases
Solution Approach 1:
The patent consolidates multiple exercise machines into a single wearable exoskeleton system, dramatically reducing the volume required for comprehensive training. Instead of transporting and setting up separate treadmills, bikes, and resistance machines, the entire training suite is integrated into one compact device that can be worn by the user
Solution Approach 2:
The exoskeleton serves as a universal training platform that provides multiple exercise modalities in a single compact form factor, eliminating the need for multiple separate machines and their associated space requirements
3Ease of operation
If traditional exercise machines are used, then basic exercise functions are provided, but immersive training experience is limited
Solution Approach 1:
The patent introduces virtual reality technology as an intermediary that enhances the basic exercise function with immersive visual and sensory feedback. The VR component mediates between the physical exercise and the user's mental engagement, creating a more comprehensive training experience that addresses both physical and psychological needs during long-duration missions
Solution Approach 2:
The system provides multiple feedback loops including haptic feedback from the actuators, visual feedback from the virtual reality display, and performance feedback from the control system that monitors exercise metrics. This multi-sensory feedback enhances user engagement and provides real-time guidance for proper exercise form and intensity

AI summary
An exoskeleton system includes an exoskeleton (10) securable to a user (12), and a control system (36) operably connected to the exoskeleton. The control system is configured to selectably operate the exoskeleton in two or more preconfigured operating modes. A method of operating an exoskeleton includes an exoskeleton securable to a user, and selecting one of two or more preconfigured operating modes of the exoskeleton via user input to a control system operably connected to the exoskeleton.
