Kneeling Support Frame With Pivoting Wheels for Stable Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for working activities, particularly in the mechanical field, do not effectively support users in a knelt down position, leading to fatigue and instability, as they fail to facilitate easy transitions between standing and kneeling, and often cause discomfort and interference with the work zone.
Innovation Solution
A supporting device with a 'T' or 'Y' shaped metallic frame, featuring three wheels including a pivotable wheel, and knee pads, designed to maintain stability and comfort by allowing easy movement and weight distribution, reducing the number of components and assembly costs, and allowing ergonomic positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a supporting device is designed to enable working in a knelt down position, then working comfort is improved, but device complexity increases
Solution Approach 1:
The supporting device is divided into distinct functional segments: a base with wheels for mobility, a support surface for knee placement, and a backrest for upper body support. This segmentation allows each component to be optimized independently while maintaining overall simplicity
Solution Approach 2:
The supporting device integrates multiple functions into a single unit: it provides knee support, back support, and mobility through wheels, eliminating the need for multiple separate devices and reducing overall system complexity
2Ease of operation
If the supporting device includes mobility features, then ease of movement is improved, but stability deteriorates
Solution Approach 1:
The device employs a dynamic wheel mechanism that allows easy movement when force is applied but provides stability when stationary, with the wheels designed to lock or resist unintended movement while maintaining mobility on demand
Solution Approach 2:
The base features localized stability mechanisms such as footrests positioned at specific angles and wheels with controlled friction characteristics, providing stability in critical areas while maintaining overall mobility
3Ease of operation
If the supporting device is designed for easy transport, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The device is constructed from modular components that can be easily assembled and disassembled, with standardized connection points that tolerate normal manufacturing variations while maintaining functional integrity
Solution Approach 2:
The design incorporates adjustable parameters such as wheel configuration and support surface positioning that can be modified to accommodate manufacturing tolerances while maintaining ease of transport functionality
