Hinged Chest Support Assembly for Hands-Free Kneeling Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals who work on their hands and knees often experience significant pain in their lower back, knees, and wrists due to prolonged periods in these positions, highlighting a need for a support device to alleviate this strain.
Innovation Solution
A body support device featuring a chest-mounted design with a hinged leg assembly and locking mechanism, allowing for adjustable support and relief from weight-bearing stress on the lower back and knees.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed support device is used to distribute body weight, then support effectiveness is improved, but user mobility is restricted
Solution Approach 1:
The leg assembly is designed with hinged joints that allow dynamic adjustment of the leg angle relative to the chest plate. Users can modify the leg position to adapt to different working conditions and body positions, providing both support when needed and flexibility when moving, thus resolving the contradiction between fixed support and user mobility
2Adaptability or versatility
If a hinged leg assembly is used to improve adjustability, then user comfort is improved, but device complexity increases
Solution Approach 1:
The support device is divided into distinct modular components: a chest plate with attachment means, a separate leg assembly with hinged joints, and connection interfaces. This segmentation allows the hinged leg assembly to provide adjustability while keeping each component relatively simple in design, reducing overall device complexity while maintaining adaptability
3Object-affected harmful factors
If weight distribution is increased to reduce strain on lower back, then health benefit is improved, but device structure becomes more complex
Solution Approach 1:
The leg assembly acts as a counterbalancing element that provides upward support force to offset the downward gravitational force on the user's body. By positioning the leg to create a lever arm relative to the chest plate, the device generates a counterbalancing moment that reduces the strain on the user's lower back without requiring complex active mechanisms
