Solution Overview

Problem

Existing exoskeleton technologies face issues with battery placement, leading to snag hazards, increased mass, and power losses due to long cables, which affect user comfort and performance.

Innovation Solution

A local battery system is integrated into the exoskeleton, located near the knee, eliminating the need for external cables and reducing mass, while a battery management system ensures efficient power delivery and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a local battery system is integrated into the exoskeleton near the knee, then snag hazards are eliminated and power losses are reduced, but device complexity increases

Engineering Contradiction:
Improvesnag hazard eliminationVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates the battery system directly into the exoskeleton structure at the knee location, merging previously separate components (external battery pack, long cables, power management unit) into a unified integrated system. This eliminates snag hazards from external cables and reduces power losses while managing the increased complexity through systematic integration.

Inventive Principle:
Principle #5Merging (Combining)

2Weight of moving object

If a local battery system is integrated into the exoskeleton near the knee, then mass is reduced by eliminating long cables, but device complexity increases

Engineering Contradiction:
ImprovemassVSAvoiddevice complexity
Core Design Contradiction:
Weight of moving objectVSDevice complexity

Solution Approach 1:

The patent extracts and eliminates the unnecessary long cables from the system by integrating the battery directly at the knee location. This removal of redundant components reduces overall system mass while the integrated design manages the complexity of the remaining components through efficient spatial arrangement and unified architecture.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of energy

If a local battery system is integrated into the exoskeleton near the knee, then power losses are reduced, but device complexity increases

Engineering Contradiction:
Improvepower lossesVSAvoiddevice complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent implements a power management unit that proactively manages power distribution from the locally integrated battery before power losses can occur. This preliminary power management action optimizes energy delivery and prevents power losses that would otherwise occur through long cables, while the integrated design manages complexity through unified system architecture.

Inventive Principle:
Principle #10Preliminary action

4Object-affected harmful factors

If a local battery system is integrated into the exoskeleton near the knee, then radio interference is minimized, but device complexity increases

Engineering Contradiction:
Improveradio interferenceVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent segments the exoskeleton system into distinct functional modules with the battery system as a separate integrated unit at the knee. This spatial segmentation isolates the battery and its power management electronics from other electronic components that may be susceptible to radio interference, reducing harmful electromagnetic effects while managing overall system complexity through modular integration.

Inventive Principle:
Principle #1Segmentation

AI summary

Systems and methods for providing a customized configuration for a controller of an exoskeleton device. A device can receive, via a user interface, feedback from a user indicative of a performance of the user during a movement event. The device can determine characteristics of the user for performing the movement event using a first exoskeleton boot and a second exoskeleton boot and identify properties of a route for the movement event. The device can determine using the characteristics of the user, the feedback and the properties of the route, control parameters for the first exoskeleton boot and the second exoskeleton boot to execute the movement event. The device can apply the control parameters to the first exoskeleton boot and the second exoskeleton boot for the user to operate the first exoskeleton boot and the second exoskeleton boot during the movement event.
