Multi-Fastener Socket with Adjustable Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for installing and dismounting threaded fasteners, such as nuts and bolts, are inefficient as they require sequential loading and unloading, complicating operations like tire nut replacement and bolt installation.
Innovation Solution
A tool with a cylindrical socket and attachment that accommodates multiple threaded fasteners in a row, allowing for simultaneous installation and dismounting by adjusting the attachment's position based on the number of fasteners, and featuring a magnetic attraction mechanism to prevent falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional socket is used to accommodate only one nut, then the socket structure is simple, but the nut removal and installation operations become complicated and time-consuming due to sequential loading and unloading
Solution Approach 1:
The socket is divided into multiple accommodation holes (first accommodation hole, second accommodation hole, etc.) within a single socket body, allowing multiple nuts to be held simultaneously. Each accommodation hole is independently structured but integrated into one unified socket, enabling parallel processing of multiple nuts without requiring multiple separate sockets.
Solution Approach 2:
A single socket is designed to perform multiple functions by accommodating different numbers of nuts (one nut, two nuts, or more) through its multiple accommodation holes. The socket can selectively engage with different attachment configurations, making it a universal tool for various fastening scenarios rather than requiring dedicated sockets for each nut count.
2Productivity
If the socket accommodates multiple threaded fasteners simultaneously, then operational efficiency improves, but the positioning and alignment of the attachment becomes more complex
Solution Approach 1:
The attachment is provided with multiple transmission surfaces (first transmission surface, second transmission surface, etc.) at predetermined positions before use. These surfaces are pre-configured to engage with corresponding inner peripheral surfaces of the accommodation holes, allowing the operator to simply select the appropriate attachment configuration rather than performing complex alignment procedures during operation.
Solution Approach 2:
The patent employs visual differentiation through marks or indicators on the attachment and socket components to indicate proper alignment and engagement positions. This allows operators to quickly identify correct positioning without requiring precise manual measurement or alignment, simplifying the operation of selecting and attaching the appropriate configuration.
3Productivity
If the distance between the distal end face of the socket and the contact portion is adjusted to match the length of threaded fasteners, then multiple fasteners can be accommodated in a row, but the adjustment mechanism becomes more complex
Solution Approach 1:
The attachment is designed with a movable or adjustable structure that allows the contact portion to be positioned at different distances from the distal end face of the socket. This dynamic adjustment capability enables the same attachment to accommodate threaded fasteners of different lengths by simply changing the extension distance, rather than requiring multiple fixed-position attachments.
Solution Approach 2:
The attachment components are nested within the socket structure, with the transmission surfaces and contact portions integrated into the overall socket-attachment assembly. This nested design allows for compact storage and easy replacement of attachment components while maintaining the adjustable positioning capability, reducing the overall complexity compared to external adjustment mechanisms.

AI summary
A tool includes a socket and an attachment that includes a shaft portion. The shaft portion transmits torque to the socket. The socket includes a distal end face, a proximal end face, an accommodation hole that opens in the distal end face, and a connection hole that opens in the proximal end face and is connected to the accommodation hole. The shaft portion includes an outer peripheral surface provided with a first transmission surface for transmitting torque to the inner peripheral surface of the connection hole. The accommodation hole includes an inner peripheral surface provided with a second transmission surface for transmitting torque to threaded fastener. The accommodation hole forms an accommodation space capable of accommodating threaded fasteners in a row. The shaft portion includes, at a distal end, a contact portion, which contacts one of the threaded fasteners accommodated in the accommodation space.
