Multi-Socket Screw Head for Faster Tool Engagement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional screws with different recesses require specific driving tools for fastening or loosening, leading to inefficiency and inconvenience due to the need for multiple tools and increased time for operations.
Innovation Solution
A screw head design featuring a combination of a Pozi-type socket and a drive socket with specific groove and conical portions, allowing engagement with various driving tools for efficient force delivery and easy operation with one hand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional screws with different recesses are used, then each driving tool can fit its corresponding recess, but it takes more time to complete fastening operations and efficiency is decreased
Solution Approach 1:
The screw head is designed with multiple types of recesses (slot, cross, Pozi, square, hexagonal, Torx) integrated into a single head structure, allowing one screw to accept multiple different driving tools. This multi-functional design eliminates the need for different screw types for different tools, thereby improving fastening efficiency while maintaining reliable fit between various driving tools and their corresponding recesses.
2Reliability
If multiple driving tools are carried for different recesses, then each tool can be used for its specific recess, but it is inconvenient for users to carry different driving tools and screws concurrently
Solution Approach 1:
By integrating multiple recess types into a single screw head, the invention allows users to carry only one type of screw instead of multiple screw variants. This universal design maintains the specific matching capability between driving tools and their corresponding recesses while significantly improving the convenience of carrying and storing fastening components.
3Force
If different driving tools are required for different recesses, then each tool can deliver driving force effectively, but the screw cannot be fastened or loosened quickly and smoothly
Solution Approach 1:
The multi-recess screw head enables quick switching between different driving tools without changing the screw itself. Each recess type is optimized to deliver driving force effectively for its corresponding tool, while the integrated design allows rapid selection and switching between tools, thereby improving the speed and smoothness of fastening and loosening operations.

AI summary
A screw includes a threaded shank and a head with a first surface. Communicating sockets formed in the first surface include a Pozi-type socket and a drive socket. The drive socket includes rounded portions, arched portions alternating with the rounded portions, and a conical portion connected to the rounded portions and the arched portions to define a first reference line and a second reference line parallel to a central axis of the head. The rounded portions are inclined outwardly from the first reference line, and the arched portions are inclined outwardly from the second reference line. Thus, a first room enclosed by the rounded portions and the arched portions increases gradually towards the first surface. By a combination of the above sockets, the head cooperates with different driving tools for delivering driving force efficiently and is more convenient to use.
