Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear mechanical quick release fasteners are limited in their versatility, requiring long connection paths and being specific to certain machine tools, making them inefficient for automatic tool changes and precise clamping on all types of self-centering chucks.
Innovation Solution
A linear mechanical quick release fastener with a bottom part featuring integrally formed raised locking elements and base jaws, and a top part with recesses, allowing for a universal, precise, and rapid locking and unlocking mechanism using a short linear motion, compatible with all self-centering chucks and clamping devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If dovetail-shaped connections extend over the entire coupling area, then connection stability is improved, but connection path length increases
Solution Approach 1:
The coupling area is segmented into multiple discrete locking elements (first locking element, second locking element) rather than using a continuous dovetail connection. This segmentation allows the connection to be established at multiple points simultaneously, providing stable locking without requiring a long continuous connection path.
2Reliability
If quick release fasteners are designed for specific machine tools, then locking reliability is improved, but adaptability decreases
Solution Approach 1:
The bottom part of the quick release fastener is designed with a universal mounting interface that can be attached to various types of machine tools and self-centering chucks. The standardized locking element configuration allows the same fastener design to be used across different machine tool types, providing both reliable locking and broad adaptability.
3Ease of operation
If linear motion is used for locking and unlocking, then operational simplicity is improved, but connection precision decreases
Solution Approach 1:
The locking elements act as intermediaries that convert the simple linear motion of the actuating element into precise rotational or angular positioning. The geometric shape and arrangement of the locking elements ensure that linear displacement results in accurate angular engagement, maintaining connection precision while preserving operational simplicity.

AI summary
A linear mechanical quick release fastener is operated by three movements with self-centering chucks and for mounting all types of compatible clamping devices for machining workpieces, especially on automatic precision machine tools. A bottom part has raised locking elements formed integrally in one piece one after another on a plane along a direction at right angles to a clamping direction and base jaws formed integrally in one piece, with a threaded hole for a clamping bolt and a screw element. A top part has recesses, one after another along a direction at right angles to the clamping direction, designed as a counterpiece of the locking elements. One recess is connected at an open front side to a mounting area recessed continuously, which is accessible from the top, and another recess is open on a front side. The top part can receive an upper plane of any compatible clamping device.
