Tool Interface Cavity with Stellate Contour for Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing interfaces between tool elements fail to efficiently transmit torque and ensure precise alignment, leading to potential damage and reduced usability due to open notch positions and limited compatibility with different projection designs.
Innovation Solution
The interface features a cavity with a polygonal or stellate inner contour, allowing for secure engagement of projections with curved regions, enabling the transmission of high torque and accommodating various projection designs, including polygonal and stellate shapes, thereby ensuring exact alignment and increased versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a polygonal connection with multi-tooth profile is used to transmit torque, then torque transmission capability is improved, but exact alignment of tool elements cannot be provided and open notch positions result causing damage risk
Solution Approach 1:
The cavity inner contour incorporates curved regions that replace the traditional polygonal profile with a continuous curved geometry. This curved contour enables exact alignment of tool elements while maintaining high torque transmission capability, eliminating the open notch positions that cause damage risk in conventional polygonal connections.
2Manufacturing precision
If a cavity is designed for a single specially designed projection, then exact alignment is achieved, but the range of use is limited
Solution Approach 1:
The cavity inner contour is designed with a universal curved profile that can accommodate multiple different projection designs including polygonal and stellate shapes. This single cavity design provides exact alignment for various projection types, significantly increasing the range of use without requiring multiple specialized cavity designs.

AI summary
An interface element between a first tool element and a second tool element includes a projection on one of the first and second tool elements and a cavity that receives the projection on the other of the first and second tool element. The cavity includes inner contours which are designed to receive polygonal and/or stellate projections.
