Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool holders are bulky, expensive to produce, and inefficient in terms of assembly time and redundant tool receiving areas, making them inconvenient for workers to carry and store.
Innovation Solution
A foldable tool holder made from a polypropylene plastic sheet, featuring a hanging end and a holding end with distinct heights, integrated slots, and a joint edge for easy assembly and adherence, allowing for a one-piece structure that can be conveniently carried and hung.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional tool holders are used, then they can receive various kinds of tools, but they take relatively long assembly time and are expensive to make
Solution Approach 1:
The patent merges multiple components into a single integrated body. The tool holder body, tool receiving areas, and hanging structure are formed as one piece from a single plastic sheet, eliminating the need for separate assembly steps and reducing manufacturing complexity. This directly addresses the contradiction by reducing both assembly time and manufacturing cost through integration.
Solution Approach 2:
The plastic sheet is divided into functional zones during the forming process. The body portion, tool receiving areas, and hanging end are created as distinct but integrated sections from a single sheet, allowing for efficient manufacturing while maintaining functional separation. This segmentation during forming reduces assembly time compared to conventional multi-component designs.
2Adaptability or versatility
If conventional tool holders are used, then they can receive various kinds of tools, but some tool receiving areas are not used all the time and become redundant
Solution Approach 1:
The tool holder employs removable tool receiving areas that can be dynamically adjusted or removed based on actual needs. The first and second tool receiving areas can be selectively taken out or reconfigured, allowing the structure to adapt to different tool storage requirements and eliminating redundant spaces when certain tools are not needed.
Solution Approach 2:
The tool receiving areas are segmented into separate, removable components. This allows individual tool receiving areas to be removed when not needed, reducing redundant space while maintaining the capability to receive various tools when required. The segmented design provides versatility without permanent redundancy.
3Ease of operation
If conventional tool holders are used, then they can hold tools, but they are bulky and not convenient for workers to carry
Solution Approach 1:
The tool holder is constructed from a folded plastic sheet with thin-walled structure. This flexible film-based construction achieves the required structural strength while minimizing material usage and overall volume, making the holder compact and portable for workers to carry on construction sites.
Solution Approach 2:
The tool receiving areas are designed to nest within or alongside each other when tools are removed. The first and second tool receiving areas can be positioned to minimize the overall volume of the holder, creating a compact form factor that is easy to carry while still providing adequate tool storage capacity when needed.

AI summary
A tool holder includes a foldable plastic sheet being folded and configured to include a hanging end and a holding end. The hanging end and the holding end integrally form a one piece structure. The holding end having a first edge, a second edge, a first lateral edge, and a second lateral edge, with the first and second edges and the first and second lateral edges delimiting a circumferential periphery of a receiving space in which the first and second edges are opposite each other and the first and second lateral edges are opposite each other and respectively extend from two lateral sides of the first edge to two lateral sides of the second edge. A joint edge is distal the first lateral edge extending therefrom and adhered to the second lateral edge.
