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

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate exercise machines are used, then comprehensive training capabilities are achieved, but system complexity and volume increase

Engineering Contradiction:
Improvetraining capabilitiesVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple separate exercise machines are used, then comprehensive training capabilities are achieved, but system volume increases

Engineering Contradiction:
Improvetraining capabilitiesVSAvoidsystem volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

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

Inventive Principle:
Principle #5Merging (Combining)

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

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If traditional exercise machines are used, then basic exercise functions are provided, but immersive training experience is limited

Engineering Contradiction:
Improvebasic exercise functionVSAvoidimmersive training capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Inventive Principle:
Principle #23Feedback

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.
