Convertible Refuse Container Mounting System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refuse collection systems lack versatility in handling both intermediate containers with fork receivers and those without, limiting their adaptability for different collection routes and requiring multiple vehicles or complex arrangements.
Innovation Solution
A convertible mounting system for intermediate refuse collection containers that includes elongated cylindrical members and planar arms for secure attachment to lift arms, allowing lateral movement and inversion of primary containers, enabling the same vehicle to handle both types of containers without fork receivers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional refuse collection vehicle with fixed fork receivers is used, then it can reliably collect commercial refuse with fork receivers, but it cannot handle residential containers without fork receivers
Solution Approach 1:
The mounting system is designed to perform multiple functions: it can securely attach to containers with fork receivers using the conventional fork interface, and simultaneously attach to containers without fork receivers using the alternative mounting member interface. This universal design allows a single vehicle to handle both commercial and residential container types without requiring separate vehicles or complex conversions.
Solution Approach 2:
The mounting system incorporates movable components including the extension assembly that can extend and retract, and the mounting members that can move between engaged and disengaged positions. This dynamic capability allows the system to adapt its configuration based on whether it is attaching to a container with or without fork receivers, providing versatility without permanent complexity.
2Adaptability or versatility
If multiple vehicles are used to handle different container types, then route-specific optimization is achieved, but operational complexity and costs increase
Solution Approach 1:
The mounting system enables a single refuse collection vehicle to perform the functions previously requiring multiple specialized vehicles. By integrating both fork receiver engagement capability and alternative mounting member attachment capability into one system, the vehicle can switch between commercial and residential routes without requiring fleet diversification, thereby maintaining operational efficiency while achieving route adaptability.
3Ease of operation
If the extension assembly is retracted for storage, then vehicle compactness is maintained, but lateral engagement capability is lost
Solution Approach 1:
The extension assembly is designed as a dynamic component that can change its configuration based on operational needs. When laterally engaging containers without fork receivers, the extension assembly extends to provide the necessary reach and engagement capability. When not in use, it retracts to minimize volume and maintain vehicle compactness. This dynamic volume adjustment resolves the contradiction between operational capability and storage efficiency.

AI summary
An intermediate container is provided for receiving refuse from a primary refuse container that is configured to be carried by a top-loading refuse collection vehicle lifter. The intermediate container comprises a front wall, a rear wall, opposed sidewalls, and a bottom wall defining a total refuse collection volume. An extension assembly that is configured for mounting a primary refuse collection container lifter thereon is located substantially beneath the total refuse collection volume intermediate the front wall and the rear wall, with a portion of the extension assembly being movable between a first, retracted position for storage and for dumping a primary refuse collection container and a second, extended position for engaging and releasing the primary refuse collection container at a location laterally spaced from the intermediate container refuse collection vehicle. Further, the intermediate container is free of fork receivers and includes at least one mounting member for non-destructive removable attachment to the collection vehicle lifter.
