Movable Mallet Platform Wrench for Impact Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional striking wrenches are single-head tools with integrally formed striking platforms, which can lead to accidental hand injuries when used to apply high impact forces.
Innovation Solution
A wrench with a movable mallet platform that includes a shaft with abutment surfaces and a mallet platform with striking and holding portions, allowing for sliding engagement and reducing the risk of hand injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a striking platform is integrally formed at the rear end of the handle, then the wrench can be used for striking operations, but the wrench becomes a single-head tool with limited functionality
Solution Approach 1:
The tool is divided into separate functional components: a wrench main body with driving ends and a movable mallet platform with striking portions. This segmentation allows the tool to function as both a wrench and a mallet, resolving the contradiction between versatility and structural simplicity.
Solution Approach 2:
The mallet platform is designed to be movable along the shaft rather than fixed, allowing it to be positioned as needed. This dynamic design enables the tool to adapt between different functions (wrench operation vs. striking operation) while maintaining a relatively simple overall structure.
2Force
If a hammer tool is used to hammer the handle of a conventional hand tool, then high impact force can be exerted on the fastening member, but accidental hand injury often occurs
Solution Approach 1:
The mallet platform acts as an intermediary between the striking tool and the wrench handle. It provides a dedicated striking surface that directs the impact force through the shaft to the fastening member, preventing the striking tool from contacting the user's hand and eliminating the hand injury risk while maintaining high impact force.
3Area of stationary object
If the mallet platform is slidably sleeved on the wrench main body, then the striking surface area is increased and hand injury is reduced, but the device complexity increases
Solution Approach 1:
The mallet platform is designed as a slidable component that can move along the shaft, providing a larger striking surface area when needed. The sliding mechanism is simple, involving basic engagement surfaces and positioning features, which minimizes the increase in device complexity while achieving the desired functional improvement.

AI summary
A wrench with a movable mallet platform is proposed. The wrench with a movable mallet platform includes a wrench main body and a mallet platform. The wrench main body includes a shaft. The shaft includes at least one abutment surface. The mallet platform is slidably sleeved on the wrench main body, and includes at least one striking portion and two holding portions. An engagement surface extends toward the shaft from at least one striking portion, and the engagement surface abuts against the at least one abutment surface. The two holding portions are disposed opposite to each other, and each of the two holding portions is connected to the at least one striking portion. Thus, the wrench with a movable mallet platform of the present disclosure can be struck by a striking tool, thereby fastening or releasing a fastening member.
