Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation of vehicle components in a power train assembly typically requires multiple people due to the weight and complexity of the components, making the process time-consuming and difficult to execute with conventional fastening tools.
Innovation Solution
A fastening tool equipped with a gear train and a magnetic socket, which rotates between non-operated and operated positions, allowing a single user to efficiently install fasteners by compressing the tool to push fasteners through flanges and secure nuts, utilizing a one-way clutch and rack mechanism for controlled rotation and magnetic retention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional fastening tools are used, then the tool structure is simple, but multiple people are required to operate the tool due to the weight and complexity of vehicle components
Solution Approach 1:
The patent combines multiple functions into a single integrated tool: the fastener holder, gear train, socket, and one-way clutch are merged into one device. This allows a single user to perform operations that previously required multiple people, as the tool integrates fastener storage, rotational motion generation, and fastener application capabilities.
Solution Approach 2:
The tool incorporates dynamic elements including a movable gear train that rotates between engaged and disengaged positions, and a one-way clutch that allows rotation in one direction while preventing reverse rotation. These dynamic components enable the tool to adapt to different operational states and perform complex fastening operations with single-user control.
2Productivity
If conventional fastening tools are used, then the tool is easy to manufacture, but the installation process is time-consuming and requires multiple personnel
Solution Approach 1:
The fasteners are pre-loaded into the holder before the fastening operation begins. The gear train is pre-configured to provide the necessary rotational motion. This preliminary preparation allows the actual fastening operation to proceed quickly without requiring multiple people or repeated setup steps, thereby increasing installation speed.
Solution Approach 2:
The one-way clutch enables the socket to rotate and apply fasteners automatically as the gear train rotates, without requiring additional manual intervention. The tool performs the fastening action itself once initiated, reducing the need for continuous human operation and increasing productivity.
3Adaptability or versatility
If the tool rotates between non-operated and operated positions, then the fastening operation can be performed, but the socket must be rotatably supported to the gear assembly
Solution Approach 1:
The socket is nested within the gear assembly structure, with the socket rotatably supported to the gear train. This nested configuration allows the socket to rotate with the gear train while maintaining a compact overall structure, enabling position adjustment without adding significant external complexity to the tool.

AI summary
A fastening tool includes a gear train and a socket. The gear train rotates as the fastening tool moves between a non-operated position and an operated position. The socket receives a fastener at a first end of the fastener. The socket is rotatably supported to the gear assembly so that the socket rotates as the gear assembly rotates.
