Quick-Coupling Hook Spring Geometry for Easier Lock Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing quick-coupling hook requires a complicated manual movement sequence for operators to transition the actuating component from the operating position to the setting-up position, leading to difficulty in quick and secure coupling and decoupling of agricultural tools.
Innovation Solution
The design of the quick-coupling hook incorporates a pre-tensioning spring with an eccentric force application, allowing the actuating component to be translated and tilted automatically into the setting-up position through an eccentric pre-tensioning force, facilitated by a virtual straight connecting line that ensures a significant distance difference between two hook body-side abutment formations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the actuating component is secured in the setting-up position through latching engagement, then the coupling connection is secure and reliable, but the movement sequence becomes complicated and difficult to operate
Solution Approach 1:
The actuating component is designed to automatically engage with the latching formation and secure itself in the setting-up position through the eccentric pre-tensioning force generated by the spring, eliminating the need for complex manual manipulation or additional actuation steps by the operator
Solution Approach 2:
The eccentric positioning of the spring bearing relative to the abutment formations creates a curved force application path that naturally guides the actuating component into the correct engagement orientation with the latching formation, simplifying the operator's task while ensuring reliable locking
2Ease of operation
If the virtual straight connecting line passes at a significant distance from the first abutment formation, then the actuating component moves easily into the setting-up position, but the structural design becomes more complex
Solution Approach 1:
The hook body is designed with asymmetric abutment formation positioning relative to the spring bearing, creating an eccentric geometry where the virtual straight connecting line naturally passes at a significant distance from the first abutment formation. This asymmetric design generates the desired mechanical advantage and automatic guidance effect while integrating smoothly into the overall structure

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design simplifies the operation, enabling even untrained operators to successfully move the actuating component into the setting-up position with ease, enhancing the efficiency and reliability of coupling and decoupling agricultural tools.
Implementation Method 1
The actuating component exhibits a force application formation which is configured, through force application thereon, to move the actuating component starting from the operating position against the effect of the pre-tensioning spring in the direction of the setting-up position
Implementation Method 2
A pre-tensioning spring which extends between a hook body-side spring bearing and an actuating component-side spring bearing and which pre-tensions the actuating component towards its operating position

AI summary
A quick-coupling hook having a hook body, a securing lock, an actuating component coupled with the securing lock for common movement, a pre-tensioning spring, a first hook body-side abutment formation on a first side of the actuating component, and a second hook body-side abutment formation on a second side of the actuating component opposite to the first side, where the pre-tensioning spring extends between a hook body-side and an actuating component-side spring bearing and pre-tensions the actuating component towards its operating position, where the actuating component in its operating position abuts against the first and against the second hook body-side abutment formation, where it is provided that in a reference state of the quick-coupling hook, in which the actuating component is in an operating position and the securing lock in a decoupling-preventing securing position, a virtual straight connecting line passing through both the hook body-side spring bearing and the actuating component-side spring bearing of the pre-tensioning spring exhibits at least double the distance from the first hook body-side abutment formation as it does from the second hook body-side abutment formation.
