Powered Exoskeleton Stabilizing Structure for Load Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Powered exoskeletons experience instability during use, particularly when supporting heavier loads or in situations requiring enhanced stability, which can lead to reduced functionality and increased risk of accidents.
Innovation Solution
A stabilizing structure is integrated into the powered exoskeleton, featuring a retractable and rotatable supporting rod system that can be unfolded to contact the ground, providing additional support and stability by forming triangular structures that enhance the exoskeleton's stability and support capabilities.

1Force
If the powered exoskeleton supports heavier loads, then the load-bearing capacity is improved, but the stability deteriorates
Solution Approach 1:
The patent introduces a stabilizing structure that extends from the leg connection rod to the ground, adding a vertical dimension of support. This creates a three-point contact system (two feet plus the stabilizing structure contact point with the ground) that forms a stable triangular support base, preventing the exoskeleton from tipping backward when carrying heavy loads.
Solution Approach 2:
The stabilizing structure acts as an intermediary element between the leg connection rod and the ground. It includes a contact member that interfaces with the ground and a supporting rod that transmits forces, thereby mediating the interaction between the exoskeleton system and the external environment to enhance stability during heavy load operations.
2Stability of the object's composition
If a stabilizing structure is added to improve stability, then the stability is improved, but the device complexity increases
Solution Approach 1:
The stabilizing structure is segmented into distinct functional components: a contact member for ground interaction, a supporting rod for force transmission, and a driving member for controlled deployment. This segmentation allows each component to be optimized independently and simplifies the overall control mechanism, as the driving member can independently manage the deployment and retraction of the stabilizing structure without affecting other exoskeleton functions.
Solution Approach 2:
The stabilizing structure is designed to be dynamically deployable rather than permanently fixed. The driving member enables the stabilizing structure to transition between extended and retracted states, allowing the exoskeleton to adapt its stability characteristics based on operational needs. This dynamic capability maintains stability when required while minimizing complexity and space constraints during normal operation.

AI summary
The present disclosure relates to a powered exoskeleton. The powered exoskeleton includes a leg connection rod and a stabilizing structure. The stabilizing structure is mounted on the leg connection rod. The stabilizing structure is switched between a folded state and an unfolded state in such a manner that the stabilizing structure is folded on the leg connection rod when the stabilizing structure is in the folded state, and the stabilizing structure is suitable for being in contact with the ground and supports the leg connection rod in a tilted upward direction when the stabilizing structure is in the unfolded state.
