Releasable Hinged Support Leg for Hands-Free Kneeling Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals working on their hands and knees often experience significant lower back, knee, and wrist pain due to prolonged periods in this position, necessitating a support device for both daily work and post-injury recovery.
Innovation Solution
A chest-mounted support device with a hinged leg mechanism that allows for adjustable positioning and attachment to the user's body, providing support and alleviating stress on the lower back and knees, while allowing hands to be free for work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the leg is made detachable with a coupling interface for releasable attachment, then the ease of operation and adaptability are improved, but the device complexity increases
Solution Approach 1:
The support device is divided into separable components: a body attachment portion and a leg portion connected through a coupling interface. This segmentation allows the leg to be detached and reattached, improving ease of operation and adaptability while managing complexity through modular design
Solution Approach 2:
The coupling interface incorporates a locking mechanism that transitions between locked and unlocked states, enabling dynamic attachment and detachment of the leg. This dynamic feature allows the device to adapt between fixed and movable configurations, balancing operational flexibility with structural simplicity
2Adaptability or versatility
If the leg is configured for hinged movement between extended and retracted positions, then the adaptability and comfort are improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The leg is designed with hinged joints that enable dynamic movement between extended and retracted positions. This dynamic configuration allows the leg to adapt to different working positions and user needs, improving versatility while maintaining relatively simple mechanical structures
Solution Approach 2:
The hinged leg mechanism allows change in the geometric parameters of the support device, specifically the distance and angle between the body attachment portion and the support point. This parameter variability enhances adaptability without requiring complex control systems

AI summary
A body support device includes a body attachment portion configured for attaching the body support device to a body of a user, a leg comprising an elongate member having an elongate body having a central longitudinal axis, the leg configured for coupling with the body attachment portion, the elongate member configured for hinged movement between extended and retracted positions, and a coupling interface for hingedly coupling the leg to the body attachment portion, such that the leg is configured for hinging between extended and retracted positions relative to the body attachment portion, wherein the coupling interface is configured for slidably releasable attachment with the at least one receiving channel on the body attachment portion.
