Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exoskeleton systems require external tools or devices for attachment and detachment, which can be cumbersome and inefficient.
Innovation Solution
An exoskeleton system with a shin pad that can be attached or detached to a boot without using external tools, utilizing a quick disconnect mechanism involving adapters and actuators to lock into place, allowing for reinforced engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional attachment mechanism is used, then the exoskeleton can be securely attached to the boot, but external tools or devices are required for attachment and detachment which makes the process cumbersome and inefficient
Solution Approach 1:
The attachment mechanism enables the exoskeleton to be attached and detached without external tools or devices. The quick disconnect mechanism allows the operator to simply push or pull the exoskeleton to engage or disengage the connection, making the system self-servicing during attachment operations.
Solution Approach 2:
The attachment mechanism is divided into separate components: a first structure on the boot and a second structure on the exoskeleton. These segmented parts can independently engage and disengage, allowing for tool-free attachment while maintaining secure connection during use.
2Reliability
If a simple attachment mechanism is used, then the exoskeleton can be easily attached and detached, but the engagement may not be sufficiently reinforced which could compromise reliability
Solution Approach 1:
The attachment mechanism transitions from a static connection to a dynamic one. During attachment, the second structure is inserted into the first structure and then rotated or moved to lock into place. This dynamic movement allows the connection to be easily made and broken while ensuring secure engagement during operation.
Solution Approach 2:
The attachment mechanism incorporates a preliminary insertion phase followed by a locking phase. The second structure is first inserted into the first structure, then rotated or moved to engage locking features that reinforce the connection before full operational use begins.
3Ease of operation
If the exoskeleton requires tool-free attachment, then user convenience is improved, but the attachment mechanism may become more complex requiring specialized structures
Solution Approach 1:
The first and second structures serve multiple functions: they provide alignment during insertion, secure connection during engagement, and enable tool-free operation. These universal structures replace what would otherwise require separate alignment features, locking mechanisms, and tool interfaces.
Solution Approach 2:
The second structure is inserted into the first structure during attachment, creating a nested configuration. This nesting arrangement allows the smaller second structure to be housed within the larger first structure, enabling compact storage and easy engagement without requiring complex external fastening mechanisms.

AI summary
An apparatus for an active exoskeleton boot is provided. The apparatus can include a foot plate disposed within a boot of a user. The apparatus can include a first adapter extending from a side surface of the foot plate having a slot and an actuator module comprising a chassis and a post, and the post coupled to the chassis. The apparatus can include a second adapter extending from an end surface of the post. The slot of the first adapter can be configured to engage the second adapter when the actuator module is positioned at a first angle relative to the first adapter. The first adapter can be configured to lock with the second adapter when the actuator module rotates from the first angle to a second angle relative to the first adapter.
