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 assembly and locking mechanism, allowing for adjustable positioning and distribution of body weight to alleviate strain on the lower back and knees, while freeing hands for work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinged leg assembly is provided for movement within a pivot range, then adaptability to different working positions is improved, but device complexity increases due to the addition of hinge and locking mechanisms
Solution Approach 1:
The leg assembly incorporates a hinge mechanism that allows dynamic movement within a pivot range, enabling the leg to be positioned at various angles to accommodate different working positions and user preferences
Solution Approach 2:
The leg assembly is divided into separable components including the leg member, hinge assembly, and locking mechanism, allowing independent adjustment and positioning of each segment to achieve optimal support configuration
2Reliability
If a locking assembly is added to fix the leg in position, then reliability of support is improved, but device complexity increases
Solution Approach 1:
The locking assembly is pre-configured to engage with the hinge mechanism, automatically securing the leg in its selected position without requiring additional manual intervention or complex control systems
Solution Approach 2:
The locking mechanism is designed to self-engage and self-lock when the leg is positioned, using the existing hinge structure and gravitational forces to maintain the locked state without continuous power or complex actuation systems
