Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wrench devices with pivoting tool heads are limited by their size, making them unsuitable for small workspaces, and have complex component structures that complicate replacement and lead to operational issues due to detachable parts.
Innovation Solution
A wrench device design featuring a handle with a fork portion and screwing portion, a driving member with an extruding portion, and a driving sleeve with a buckling ring, allowing for adaptable operation in various spatial sizes by pivoting and sleeving mechanisms, enabling easy assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional wrench device with a pivoting tool head is used, then it can operate in working places with small spatial size, but it cannot be used in working places with spatial sizes smaller than the tool head
Solution Approach 1:
The tool head is divided into a fixed portion and a movable portion that can pivot relative to each other. The movable portion can be rotated to different positions, allowing the wrench to adapt to various spatial configurations and work in places with limited space that would be inaccessible to a conventional fixed-size tool head.
2Ease of repair
If each component of the conventional wrench is designed to be replaceable, then it facilitates maintenance, but the complicated structure makes it difficult to replace broken components
Solution Approach 1:
The fixed portion and movable portion of the tool head are connected through a simple pivoting connection that allows for easy assembly and disassembly. This merging of components with a straightforward connection mechanism enables users to replace broken parts without dealing with complex structural relationships, thus improving ease of repair while keeping the overall structure simple.
3Adaptability or versatility
If multiple small components are used in the conventional wrench, then the device achieves complex functionality, but tiny components would detach and be lost under long term use
Solution Approach 1:
The pivoting connection between the fixed portion and movable portion integrates the connection function directly into the structural components themselves, eliminating the need for separate small fastening components. This merging of connection functions into the main structural elements prevents tiny components from detaching and being lost during long-term use, while still achieving the required functional capability.
4Adaptability or versatility
If a pivoting mechanism is added to the wrench device, then it can adapt to small spatial sizes, but the device complexity increases
Solution Approach 1:
The tool head is segmented into fixed and movable portions connected by a simple pivot. This segmentation allows the wrench to adapt to spatial constraints through the pivoting action of the movable portion, while keeping the mechanism itself simple and avoiding the need for complex actuating systems or multiple moving parts.

AI summary
A wrench device includes a handle, a driving member and a driving sleeve, the handle having a fork portion defined at one end thereof, the fork portion being pivotally assembled with the driving member, the handle having a screwing portion defined at another end thereof, a screwing hole being opened at one end of the screwing portion, an opening of the screwing hole being opposite to the fork portion, the driving sleeve sleeving on an outer periphery of the screwing portion. Under this arrangement, a user applies a sleeving member to sleeve on the driving member so as to screw or unscrew a bolt; in addition, the user also can operate the screwing portion of the wrench device to screw or unscrew the bolt.
