Solution Overview

Problem

Construction dumpsters are often labor-intensive to fill due to the need for manual deposition of materials, and existing methods for lifting and emptying materials often result in incomplete filling and material loss.

Innovation Solution

A container lift apparatus comprising a lift platform supported by a lift frame that can be positioned on the side of a construction dumpster, allowing for easy attachment and detachment. The lift platform can be raised and tilted using an elevating mechanism, enabling efficient filling and emptying of materials into the dumpster.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If materials are manually deposited into the construction dumpster, then the filling process can be completed, but the labor intensity is high and the filling efficiency is low

Engineering Contradiction:

Improvefilling efficiencyVSAvoidlabor intensity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The container lift acts as an intermediary device between the ground level and the construction dumpster. It provides a mechanical lifting system that transfers materials from ground level to the dumpster, eliminating the need for manual lifting and deposition while reducing labor intensity and increasing filling efficiency.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual mechanical operations (hand-carrying and throwing materials) with a mechanical lifting system. The container lift uses a motorized or hydraulic lifting mechanism to raise the container, substituting human physical effort with automated mechanical force.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Productivity

If a door is used to push materials into the construction dumpster with a skid steer or tractor, then some materials can be pushed in, but the container cannot be completely filled as material falls out of the door

Engineering Contradiction:

Improvefilling completenessVSAvoidmaterial loss

Core Design Contradiction:

ProductivityVSLoss of substance

Solution Approach 1:

The container lift raises the container to the dumpster edge before tilting and dumping. This preliminary positioning ensures materials are deposited precisely at the target location without falling out during transfer, achieving complete filling while preventing material loss.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The lift platform replicates the dumping function of traditional methods but with improved precision. By controlling the tilting mechanism, the system copies the material transfer process while eliminating the uncontrolled spilling that occurs with door-based methods.

Inventive Principle:

Principle #26Copying

3Productivity

If the lift platform is raised to the edge of the dumpster, then materials can be effectively deposited, but the platform must be lowered to ground level for refilling

Engineering Contradiction:

Improvedeposition effectivenessVSAvoidcycle time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The container lift enables continuous operation by rapidly cycling between raising for deposition and lowering for refilling. The mechanical system maintains continuous useful action by eliminating idle time between operations, allowing quick transitions that minimize cycle time while maintaining effective material deposition.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

A container lift apparatus for raising and depositing material into a dumpster. The apparatus has a lift frame to be secured to the side of the dumpster that also allows the apparatus to slide or roll on the side of the dumpster. A lift platform can dock at ground level receives material or objects thereon and is raised to an edge of the dumpster. A elevating mechanism and one or more levers tilt the lift platform, to slide the material off into the dumpster. The frame can adjust for different dumpster sizes. The upper end of the frame supports the apparatus on an edge of the dumpster and the bottom end can support the frame on the ground and can be raised to move the apparatus on the side of the dumpster.
