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

VSEngineering 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

Engineering Contradiction:
Improveangular position adaptation accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

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

Inventive Principle:
Principle #25Self-service

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

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If an operator supervises the adaptation process with video camera aid, then the adaptation reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:
Improveadaptation reliabilityVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

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

Inventive Principle:
Principle #25Self-service

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

Engineering Contradiction:
Improvedevice complexityVSAvoidangular position adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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

Inventive Principle:
Principle #15Dynamics
