Toolbox External Hanger Assembly for Space-Constrained Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited dimensions and space of storage boxes prevent effective storage of items like battery packs, horizontal scales, cables, and chemicals, leading to inconvenience and potential damage when external connecting devices are used.
Innovation Solution
A toolbox system comprising a storage box with an accommodation cavity and an external hanger assembly for detachable item connection, featuring a limiting portion and mounting structure for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If items are placed inside the storage box, then storage capacity is improved, but items like battery packs, horizontal scales, and cables cannot be stored due to limited space
Solution Approach 1:
The patent transitions from two-dimensional internal storage to three-dimensional external storage by adding hanger assemblies that extend outward from the storage box. This allows items like battery packs and cables to be stored vertically or horizontally on the exterior, effectively utilizing spatial dimensions that were previously unavailable and resolving the conflict between storage capacity and item compatibility.
Solution Approach 2:
The storage system is divided into multiple functional zones: internal storage compartments for small items and external hanger assemblies for larger items like battery packs and cables. This segmentation allows each zone to be optimized for specific item types, enabling the storage box to accommodate a diverse range of items that would not fit together in a single confined space.
2Reliability
If connecting devices are welded to the storage box, then item attachment is improved, but the structure of the storage box is damaged
Solution Approach 1:
The hanger assemblies are designed with detachable connections that can be easily attached and removed without permanent modification to the storage box. This dynamic connection system provides reliable attachment during use while preserving the structural integrity of the storage box, allowing users to configure and reconfigure their storage setup as needed.
Solution Approach 2:
The patent introduces intermediate mounting structures (such as adhesive mounts or clamp-based fixtures) that serve as mediators between the hanger assemblies and the storage box. These intermediaries provide secure attachment points without requiring welding or drilling into the storage box, thus maintaining structural integrity while achieving reliable item attachment.
3Ease of operation
If items are carried by free hands or scattered on the ground, then storage flexibility is improved, but convenience is reduced and damage risk increases
Solution Approach 1:
The patent merges multiple items (tools, battery packs, cables, and chemicals) into a single integrated storage system with dedicated compartments and external hangers. This consolidation eliminates the need to carry items separately or scatter them on the ground, providing convenient one-handed retrieval while protecting all items from damage through secure, organized storage.
