Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening tools for HI-LOK fasteners require manual removal of broken nut pieces from the socket wrench, which is time-consuming and inefficient.
Innovation Solution
A fastening tool equipped with a socket wrench, detachable structure, suction port, and coupling member that allows for automatic collection of broken nut pieces using suction and negative pressure generated by a rotational drive device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fastening tool with a socket wrench is used to tighten a nut on a HI-LOK fastener, then the nut can be fastened by rotating it until it breaks under specified torque, but a broken piece of the nut remains in the socket wrench requiring manual removal
Solution Approach 1:
The invention extracts the broken nut piece from the socket wrench using a suction port and vacuum generation device. The suction port is positioned to receive the broken nut piece when it is generated, and the vacuum generation device creates negative pressure to automatically suction and remove the debris from the socket wrench, eliminating manual removal steps
Solution Approach 2:
The invention introduces an intermediary suction system between the broken nut piece and the socket wrench. The suction port acts as an intermediary component that captures the broken piece, and the vacuum generation device provides the intermediary force to transport the debris away, facilitating automatic removal without direct manual intervention
2Productivity
If manual removal of broken nut pieces is required from the socket wrench, then the fastening operation can be completed, but assembly productivity decreases due to time-consuming manual intervention
Solution Approach 1:
The invention enables the fastening tool to serve itself by automatically removing broken nut pieces. The suction port and vacuum generation device work together to self-clean the socket wrench of debris without requiring external manual intervention, allowing continuous fastening operations and improving assembly productivity
Solution Approach 2:
The invention maintains continuous useful action by eliminating interruptions for manual debris removal. The automatic suction system ensures that the socket wrench is continuously ready for the next fastening operation, maintaining uninterrupted workflow and maximizing assembly productivity

AI summary
A fastening tool for fastening a nut to a bolt includes a pipe and a coupling member. The nut breaks at specified torque. The pipe has a socket wrench, a detachable structure and a suction port. The detachable structure is for attaching to and detaching from a rotor of a rotational drive device. The suction port is for suctioning a piece of the nut broken by the specified torque. The coupling member has a flow path, a first coupling portion and a second coupling portion. The flow path is for suctioning the piece of the nut from the suction port. The piece of the nut is suctioned from the suction port with an ejector. The first coupling portion couples the coupling member to a casing of the rotational drive device. The second coupling portion couples the coupling member to a duct of the ejector.
