Work Stool with Gas Strut-Linked Tray for Constant Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing work stools for automobile mechanics require users to bend more when the cushion is lifted, as the tray remains stationary, making it inconvenient to access tools.
Innovation Solution
A work stool with a gas strut-supported tray that maintains a fixed distance from the cushion, allowing for adjustable altitude and rotation, ensuring consistent access to tools regardless of the cushion's position, along with optional LED lighting for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tray is made adjustable in altitude, then tool access is improved, but the device complexity increases
Solution Approach 1:
The gas strut serves multiple functions simultaneously: it supports the cushion, supports the tray, and provides the mechanical linkage for synchronized movement between cushion and tray. This multi-functionality resolves the contradiction by achieving tray altitude adjustment without adding separate adjustment mechanisms, thereby improving tool access while minimizing device complexity.
Solution Approach 2:
The system automatically maintains the optimal distance between cushion and tray through the gas strut's inherent mechanical properties. No manual adjustment or complex control system is needed - the gas strut self-regulates the relative positions based on the cushion's position, providing altitude adjustment while keeping the mechanism simple and maintenance-free.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and ergonomic access to tools by maintaining a constant distance between the tray and cushion, reducing the need for excessive bending and enhancing usability with adjustable lighting.
Implementation Method 1
The support has a gas strut. A tray is mounted around the support so as to be positioned between the cushion and the base. A connecting assembly has one end fixedly connected to the tray and an opposite end connected to the gas strut so that a distance between the tray and the cushion is fixed and the tray is adjustable in terms of altitude by operating the gas strut.
