Detachable Prying Head for Compact Hand Tool Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large crowbar and wrench tools are cumbersome and burdensome due to their size and weight, making it difficult for workers to efficiently use them, especially in confined spaces while maintaining their original functions.
Innovation Solution
A prying head with a prying portion, supporting portion, and assembling portion, featuring a sharp edge, curved surface, and blind hole, which can be detachably assembled with a handle and wrench head, allowing for reduced volume and weight through recessed cavities and adjustable length, facilitating easier handling and use in tight spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If large crowbar and wrench tools are used to repair massive articles, then the original functions are maintained, but the volume and weight increase making workers burdened
Solution Approach 1:
The tool is divided into separate components: a head portion (crowbar or wrench) and a handle portion that can be detachably connected. This allows workers to carry only the necessary head portion or a compact handle, reducing the weight burden while maintaining full functionality when assembled.
Solution Approach 2:
The handle portion can be inserted into or nested within the head portion when not in use, creating a compact storage configuration. This nesting capability significantly reduces the volume and weight that workers need to carry, while the full-length tool is restored when assembled for operation.
2Ease of operation
If large tools with long effort arms are used, then forces can be easily applied to components in small slits, but the volume and weight of the tools increase
Solution Approach 1:
The tool is divided into a head portion containing the effort arm and a separate handle portion. The effort arm remains intact in the head portion to maintain force application capability, while the handle can be detached or nested to reduce overall volume when not in use.
Solution Approach 2:
The handle length can be dynamically adjusted or detached based on the specific task requirements. For tasks requiring long effort arms, the full handle is attached; for storage or transport, the handle is detached or nested, providing dynamic volume control while preserving operational capability.
3Adaptability or versatility
If multiple large tools are prepared simultaneously, then all necessary functions are available, but the burden of carrying them increases
Solution Approach 1:
A single handle portion can be detachably connected to different head portions (crowbar or wrench), creating a universal tool system. Workers only need to carry one handle and swap head portions as needed, replacing the need to carry multiple separate large tools while maintaining all necessary functions.

AI summary
A prying head is provided in the present disclosure. The prying head, which is used in cooperation with a hand tool, includes a prying portion, a supporting portion and an assembling portion. The prying portion includes a ground-abutting surface and an article-abutting surface. The article-abutting surface is connected to the ground-abutting surface to form a sharp edge. The supporting portion is connected to the prying portion and includes a curved surface. The curved surface is connected to the ground-abutting surface and the article-abutting surface, so as to make an end of the supporting portion away from the sharp edge into a curved form. The assembling portion is connected to the supporting portion and includes a blind hole. The blind hole is recessed from an end of the assembling portion away from the sharp edge.
