Waste Collection Coupling Arm for Fast Bilateral Container Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste collection systems require excessive time and incur high costs due to inefficient bilateral handling and potential damage from telescopic arm stresses, especially when handling containers on both sides of a vehicle.
Innovation Solution
A system with a coupling device featuring a first arm rotating 360° about a parallel axis and a second arm rotating 360° about a parallel axis, eliminating the need for telescopic elements and allowing quick, damage-free handling of containers on both vehicle sides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary base is used to rotate the entire arm about a vertical axis for bilateral container handling, then containers on both sides of the motor vehicle can be handled, but the execution time increases due to the rotation time and the system complexity increases
Solution Approach 1:
The arm is divided into multiple segments (first arm, second arm, third arm) that can rotate independently about parallel horizontal axes. This segmentation allows each segment to contribute to the positioning of the gripping means, enabling bilateral container handling without requiring rotation of the entire arm about a vertical axis, thus reducing execution time while maintaining versatility.
2Adaptability or versatility
If a rotary base is used to rotate the entire arm about a vertical axis for bilateral container handling, then containers on both sides of the motor vehicle can be handled, but the device complexity and manufacturing costs increase
Solution Approach 1:
The arm is divided into multiple segments (first arm, second arm, third arm) that can rotate independently about parallel horizontal axes. This segmentation allows each segment to contribute to the positioning of the gripping means, enabling bilateral container handling without requiring rotation of the entire arm about a vertical axis, thus reducing execution time while maintaining versatility.
3Adaptability or versatility
If telescopic elements are used in the arm for bilateral container handling, then the arm can reach containers at different distances, but the telescopic elements are subject to high torsional stresses that may cause them to get stuck or damaged
Solution Approach 1:
The arm segments are designed to rotate about parallel horizontal axes rather than using telescopic elements. The third arm can be extended or repositioned by rotation about its longitudinal axis, providing adaptability for reaching containers at different distances without subjecting structural elements to high torsional stresses, thus maintaining reliability.
