Solution Overview

Problem

Current waste removal methods involving cranes, boom vehicles, and dump trucks are inefficient, requiring multiple vehicles and trips, and are costly due to the need for separate equipment, with limited reach and high costs for equipment purchase and operation.

Innovation Solution

An extended slope container system that can be towed by a crane or boom vehicle, featuring a sloped rear wall that doubles as a ramp for easy access and a secure locking mechanism, allowing for increased volume and efficient loading and unloading of waste, reducing the need for multiple vehicles and trips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a dump box or trailer is installed on a machine with a boom or crane, then the size restriction for the dump box or trailer holding vessel is limited to the reach of said boom or crane, but a single machine can be employed for the entire task

Engineering Contradiction:
Improvesingle machine employmentVSAvoiddump box volume
Core Design Contradiction:
Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The container is mounted on a trailer that can be positioned independently of the boom reach, utilizing the third dimension (distance from the vehicle) to extend the effective working volume beyond the boom's horizontal reach limitation

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If an excavator and dump truck are used separately, then waste can be loaded and transported, but it is not economical nor practical to utilize two vehicles in many tasks

Engineering Contradiction:
Improvewaste removal efficiencyVSAvoidnumber of vehicles
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention combines the loading function (crane/boom) with the transport function (trailer-mounted container) into a single integrated system, eliminating the need for separate excavator and dump truck operations

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If a dump box is made immobile, then it can be securely positioned, but a secondary crane or backhoe is required to remove debris from the dump box

Engineering Contradiction:
Improvedump box stabilityVSAvoiddebris removal ease
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The container incorporates a movable rear wall that can be dynamically adjusted between closed and open positions, allowing the same structure to provide both stability during transport and ease of access during discharge operations

Inventive Principle:
Principle #15Dynamics

AI summary

A waste removal system with a trailer for the storage of materials such as waste or rubble, wherein the trailer has a front wall, a rear wall, and plurality of side walls with an extended slope on at least one of the walls to increase the volume capacity therein. The trailer may additionally contain a slanted access door or ramp which alternatively raises and lowers, allowing for ease of ingress and egress of the trailer volume. The waste removal system may additionally include a transport vehicle with a grappler mounted at a distal end of a boom, wherein the grappler grasps waste and deposits the waste into the previously-mentioned trailer for transport to and from a desired location.
