Hinged Tool Storage Bag for Flat Access and Compact Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool storage devices lack user-friendly designs that allow for easy access and organization of tools while minimizing the overall size when closed, particularly for tools with varying shapes and sizes.
Innovation Solution
A tool bag with a flat base body divided into surface sections by hinges, allowing these sections to fold into a polygonal solid shape, using textile material for flexibility and plastic inserts for rigidity, with magnetic elements for secure closure and holders for tools that facilitate easy access and organization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tool bag is designed to be flat and spread out for easy access to tools, then tool visibility and accessibility are improved, but the pack size and portability deteriorate
Solution Approach 1:
The base body is divided into multiple surface sections that can be independently folded relative to each other. This segmentation allows the bag to be deployed flat for tool access but collapsed into a compact polygonal solid for storage, resolving the contradiction between accessibility and pack size.
Solution Approach 2:
The bag transitions from a static flat structure to a dynamic multi-state structure that can fold and unfold. The hinges enable the surface sections to move between deployed and collapsed positions, allowing the bag to adapt its volume based on operational needs.
2Stability of the object's composition
If the base body is made rigid to maintain shape, then structural stability is improved, but flexibility and adaptability to different surfaces deteriorate
Solution Approach 1:
The base body is segmented into multiple surface sections connected by hinges. Each section can be folded independently, allowing the bag to adapt to different surface contours while maintaining structural stability when deployed flat.
Solution Approach 2:
The base body is constructed from flexible textile material that can conform to different surfaces. The flexibility of the textile material allows the bag to adapt to curved surfaces and various contours while maintaining its structural integrity when needed.
3Ease of operation
If tools are arranged with gaps for easy grasping, then tool accessibility is improved, but space utilization and compactness deteriorate
Solution Approach 1:
Tools are arranged in a nested configuration where smaller tools can be placed in the gaps between larger tools. The holding devices are positioned to create gaps that accommodate smaller tools, maximizing space utilization while maintaining accessibility for grasping.
Solution Approach 2:
The tool arrangement utilizes three-dimensional space by positioning tools at different depths and angles within the bag. Tools are oriented to create gaps in multiple dimensions, allowing smaller tools to fit into the spaces between larger tools while maintaining ease of access.
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
The design provides maximum tool visibility when open and minimal pack size when closed, with tools easily accessible and organized, suitable for various surfaces including curved ones, and featuring automatic unfolding upon opening.
Implementation Method 1
The insert plates can be magnetically equipped so that the opened device is held to a steel base by magnetic force.
Implementation Method 2
The bars are bent, in particular bent by 90°, when the tool bag is closed. They then provide a spring force that causes the tool bag to unfold automatically when its closure is opened.
