Tool Stool
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool stools with additional cushions have limited containing spaces due to compression, which hinders efficient operation and storage of tools.
Innovation Solution
A tool stool design featuring a base with a detachable first tool tray, a cushion supported by frames, an extension rack that can be unfolded or folded, and a functional tray with partitions and a tool basket, allowing for flexible and expanded storage space and improved mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cushion is added to the tool stool for operator comfort, then ease of operation is improved, but the containing space is compressed and limited
Solution Approach 1:
The extension rack is designed to be movable between extended and retracted positions. When extended, it provides additional containing space; when retracted, it maintains a compact profile. This dynamic structure allows the tool stool to adapt its containing volume based on operational needs while preserving operator comfort through the cushion.
Solution Approach 2:
The extension rack extends horizontally from the base, utilizing the lateral dimension rather than vertically compressing the existing space. This dimensional approach adds containing volume without compromising the vertical space needed for the cushion and operator access.
2Volume of moving object
If the extension rack is unfolded to provide bigger containing space, then volume is improved, but the device complexity increases
Solution Approach 1:
The tool stool is divided into modular components: a fixed base with cushion, and a separate extendable rack with functional tray. This segmentation allows the containing space to be expanded only when needed without permanently increasing the complexity of the entire structure. The modular design simplifies both the base unit and the extension unit independently.
Solution Approach 2:
The extension rack employs a simple hinge mechanism that allows it to be extended or retracted as needed. This dynamic capability provides variable containing space without requiring a permanently complex structure. The hinge connection and universal wheel enable easy deployment and storage of the extension portion.
3Ease of operation
If pulleys are installed at the corners of the base for mobility, then ease of operation is improved, but the device complexity increases
Solution Approach 1:
The pulleys serve multiple functions: they enable the tool stool to be moved easily across the workspace, and they also facilitate the extension and retraction of the rack by allowing the universal wheel to roll smoothly. This multi-functionality justifies the addition of pulleys without proportionally increasing overall device complexity.
