Flexible Carrier Part for Refuse Vehicle Loading Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing loading systems for emptying containers, such as refuse bins, experience frequent damage due to obstacles like speed bumps and kerbs, leading to high maintenance and repair costs, limited vehicle availability, and interruptions in waste collection, as the pick-up frames are not adequately protected against such impacts.
Innovation Solution
A support part for the pick-up frame is manufactured using a carrier part made from flexible plate material with a contact part that includes recesses and strengthening ribs, allowing for movement relative to the frame and absorbing vibrations and loads, thereby reducing damage. The carrier part is shaped to bend and yield upon impact, and the contact part is made from rubber for enhanced flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the pick-up frame is provided with rigid support parts to ensure structural strength, then the strength and stability are improved, but the resistance to damage from speed bumps and kerbs deteriorates
Solution Approach 1:
The support part is designed to be movable relative to the pick-up frame, allowing it to yield and bend when contacting obstacles like speed bumps or kerbs. This dynamic capability enables the structure to adapt to external impacts without suffering permanent damage, resolving the contradiction between maintaining structural strength and resisting damage from road obstacles.
Solution Approach 2:
The support part incorporates a flexible plate material that can bend and deform elastically under load. This flexibility allows the support part to absorb impact energy from speed bumps and kerbs while maintaining its load-bearing capacity, thus improving reliability without sacrificing structural strength.
2Stability of the object's composition
If the carrier part is made fixed to the pick-up frame to ensure stability, then the stability is improved, but the ability to absorb impact energy deteriorates
Solution Approach 1:
The carrier part is designed with movable connections to the pick-up frame, enabling it to tilt and rotate around a tilting point when subjected to impact forces. This dynamic movement allows the carrier part to absorb impact energy from speed bumps and kerbs, reducing the transmission of harmful forces while maintaining operational stability during normal use.
3Strength
If rigid materials are used for the carrier part to ensure load-bearing capacity, then the strength is improved, but the vibration damping capability deteriorates
Solution Approach 1:
The carrier part is constructed from flexible plate material that can bend and deform under load. This flexibility provides inherent vibration damping capability while maintaining sufficient load-bearing capacity, as the material can elastically deform to absorb vibrational energy without compromising its structural strength.
Solution Approach 2:
The support part assembly combines the flexible carrier part made from plate material with the rigid pick-up frame structure. This composite construction allows the flexible carrier part to dampen vibrations and absorb impacts, while the rigid frame provides the necessary load-bearing capacity and structural stability.
Applied Scientific Principles
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 reduces damage to the loading system by absorbing and distributing loads, preventing wear and tear on moving parts, and maintaining connectivity with the pick-up frame even under heavy loads, thus minimizing downtime and maintenance costs.
Implementation Method 1
a flexible material is arranged between the carrier part and the container in order to form a contact part... a degree of damping is also provided, whereby among other things the transmission of undesirable vibrations is limited
Implementation Method 2
The carrier part is movable relative to the pick-up frame. This is for instance relevant if the vehicle on which the loading system is arranged reverses and for instance makes contact with a speed bump or kerb. In such a case the carrier part will give away or yield or bend
Implementation Method 3
The contact part is made from rubber for enhanced flexibility... a degree of damping is also provided, whereby among other things the transmission of undesirable vibrations is limited
