Self-Aligning Waste Container Coupling Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for handling waste collection containers struggle to adapt their gripping mechanisms to the angular position of container handles without operator supervision, relying on complex sensors or artificial intelligence.
Innovation Solution
A device with a coupling head attached to a crane arm, featuring rotatable movable elements that self-align with the container handle using a rotation device and control unit, allowing for automatic adaptation of the gripping mechanism to the handle's angular position without requiring sensors or AI, and enabling both handling and emptying of containers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If complex sensors or artificial intelligence are used to adapt the gripping mechanism to the handle's angular position, then the adaptation accuracy is improved, but the device complexity increases
Solution Approach 1:
The gripping mechanism automatically adapts to the handle's angular position through self-alignment when the movable elements move toward the handle, eliminating the need for external sensors or AI systems to detect and adjust the position
Solution Approach 2:
The patent replaces complex electronic sensing and control systems with a purely mechanical self-aligning mechanism where the geometry of the movable elements and handle interface enables automatic angular position adaptation through physical contact
2Reliability
If an operator supervises the adaptation process with video camera aid, then the adaptation reliability is improved, but the ease of operation deteriorates
Solution Approach 1:
The system performs the adaptation function autonomously through the self-aligning mechanical mechanism without requiring operator intervention or supervision, making the operation simpler while maintaining reliability through the inherent mechanical alignment capability
3Device complexity
If the gripping mechanism is fixed in angular position, then the device complexity is reduced, but the adaptability to different handle positions deteriorates
Solution Approach 1:
The gripping mechanism transitions from a fixed angular position to a dynamic self-aligning system where the movable elements can rotate or pivot to match the handle's angular position automatically, providing adaptability without adding complex control systems
