Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand-held impact tools require manual hammering to unscrew tightly stuck threaded elements, which is labor-intensive, time-consuming, and prone to accidental injuries, and lack a mechanism for direct mounting on power-driven impact tools.
Innovation Solution
A power-driven impact tool assembly comprising a grip with a tubular member, a connector, and a tool head, utilizing a non-circular positioning hole and a connector with an annular slope and insertion section to stabilize the connector, allowing for direct mounting and efficient rotation of stuck threaded elements using compressed air.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual hammering is used to unscrew tightly stuck threaded elements, then the tool can be operated with simple structure, but the operation becomes labor-intensive and time-consuming
Solution Approach 1:
The patent replaces the manual hammering mechanical system with a pneumatic impact system. A pneumatic impactor generates controlled impact forces automatically, eliminating the need for manual hammering while significantly improving unscrewing efficiency and reducing operator labor intensity.
Solution Approach 2:
The patent introduces a pneumatic impactor that uses compressed air to generate rapid impact forces. The pneumatic system delivers controlled blows to the threaded element through a specialized adapter, replacing manual hammering with automated pneumatic actuation for higher productivity.
2Device complexity
If manual hammering is used to unscrew tightly stuck threaded elements, then the device structure remains simple, but the operation becomes prone to accidental injuries
Solution Approach 1:
The patent replaces the dangerous manual hammering operation with an automated pneumatic impact system. The pneumatic impactor contains the impact forces within a controlled mechanism, eliminating the risk of accidental hand injuries while maintaining the ability to deliver sufficient impact forces for unscrewing stuck elements.
Solution Approach 2:
The patent introduces a specialized adapter as an intermediary component between the pneumatic impactor and the threaded element. This adapter safely transmits the impact forces from the pneumatic system to the nut, providing a secure interface that protects the operator from direct exposure to impact forces.
3Ease of operation
If conventional hand-held impact tool is used, then the tool can be operated manually, but it cannot be directly mounted on power-driven impact tools
Solution Approach 1:
The patent designs a universal adapter system that enables compatibility between pneumatic impactors and various socket bits. The adapter incorporates standardized mounting features that allow it to be used with different power-driven impact tools and different sized sockets, significantly improving versatility and adaptability.
Solution Approach 2:
The patent divides the tool system into separable components: a universal adapter body, interchangeable socket bits, and a pneumatic impactor. This segmentation allows the adapter to be mounted on different power-driven tools while maintaining compatibility with various socket sizes, enhancing system flexibility and adaptability.
