Waste Container Coupling Head Overload Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling waste collection containers lack mechanisms to prevent overload damage to gripping jaws due to misalignment or improper placement, which can lead to jaw damage or breakage under high forces from fully loaded containers.
Innovation Solution
A device with a coupling head attached to a crane arm featuring movable elements with resilient springs that move to an overload position when excessive force is applied, allowing geometric interference with the container handle to prevent damage, and a control unit to manage handle gripping, release, and gate operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first movable elements are made firmly gripping to secure the container handle, then the holding reliability is improved, but the jaws become vulnerable to overload damage when misalignment occurs
Solution Approach 1:
The first movable elements are designed to be movable between a handle gripping position and an overload position. The resilient elements enable dynamic response to overload conditions, allowing the system to adapt its gripping force and protect against damage while maintaining secure holding during normal operation
Solution Approach 2:
Resilient elements are incorporated into the first operating means to provide beforehand cushioning against overload forces. These resilient elements allow the movable elements to move to an overload position when excessive force is detected, preventing direct transmission of damaging forces to the jaws while maintaining functional gripping capability
2Stability of the object's composition
If the movable elements are made rigid to ensure stable gripping, then the gripping stability is improved, but the device cannot accommodate misalignment without causing overload
Solution Approach 1:
The system transitions from a static rigid gripping structure to a dynamic system where movable elements can change position in response to loading conditions. The resilient elements enable the structure to adapt its configuration, maintaining stability during normal gripping while accommodating misalignment through controlled movement to the overload position
Solution Approach 2:
The system changes its mechanical parameters dynamically - during normal operation, the movable elements maintain a stable gripping configuration, but when overload occurs, the resilient elements allow parameter changes by enabling movement to the overload position, thereby accommodating misalignment without compromising gripping stability during functional operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents jaw overload and damage by moving elements to an overload position when excessive force is detected, ensuring secure handling and operation of waste containers without compromising the gripping mechanism, while also enabling safe emptying and positioning of containers.
Implementation Method 1
the first operating means comprise resilient elements configured to move a first movable element from the handle gripping position to the overload position when a force exerted by the container handle exceeds a threshold
