Adjustable Pry Bar With Pivoting Socket Driver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pry bars require users to switch between tools for tasks like tightening or loosening fasteners, which is time-consuming and inconvenient.
Innovation Solution
An adjustable pry bar with a pivoting device that allows integration of a driving tool function, enabling seamless transition between pry and driving operations through a pivoting mechanism and a biasing member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users carry multiple driving tools for different tasks, then task versatility is improved, but device complexity and portability are worsened
Solution Approach 1:
The patent combines a pry bar with a driving tool (socket wrench) into a single integrated device. The pry bar handle contains a hollow cavity that accommodates the driving tool mechanism, allowing users to perform both prying and fastening operations with one tool rather than carrying separate tools.
Solution Approach 2:
The pry bar is designed with multiple functions: it can be used for prying operations with the pry head, and for driving or loosening fasteners using the integrated driving tool with interchangeable sockets. This multi-functionality eliminates the need to carry multiple specialized tools.
2Reliability
If users switch between pry bar and driving tool, then task specialization is improved, but time efficiency is worsened
Solution Approach 1:
The driving tool is integrated within the pry bar handle structure, allowing immediate transition between prying and driving tasks without putting down the tool or reaching for a separate driving tool, thus eliminating tool switching time.
Solution Approach 2:
The driving tool mechanism is pre-positioned and ready for use within the pry bar handle. Sockets can be quickly exchanged in advance, so when a driving task is needed, the appropriate socket is already in place or can be rapidly swapped without delaying the workflow.
3Ease of manufacture
If pry bar structure is simplified, then ease of manufacture is improved, but functionality is worsened
Solution Approach 1:
The driving tool mechanism is nested within the hollow cavity of the pry bar handle. This nesting approach allows the complex driving tool functionality to be housed within the existing pry bar structure without requiring a completely new complex tool design, maintaining relative manufacturing simplicity while adding functionality.

AI summary
An adjustable pry bar includes a rod, a pry head, and a pivoting device. The pivoting device includes an engaging member, an axial member, and a positioning member. The engaging member is movably inserted through the rod and the pry head. The axial member is movably inserted through the pry head and the engaging member. The positioning member is movably disposed in the engaging member and is configured to enter the axial member as the axial member moves relative to the pry head and the engaging member, allowing the positioning member to selectively protrude from the engaging member and to be adapted for connecting to a driving tool.
