Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing stackable heavy equipment buckets require significant space and time to maneuver for efficient stacking due to their design, leading to inefficient storage and shipping.

Innovation Solution

The design features a bucket with a tapered floor and parallel top wall sides that include a diagonal bend, allowing for efficient nesting and connection, along with the use of double-ended reverse hooks for additional stability and spacing, enabling quicker and more compact stacking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If buckets are designed with traditional stacking configurations, then they can be stacked for storage and shipping, but they require significant space and time to maneuver into position

Engineering Contradiction:

Improvestacking efficiencyVSAvoidtime to maneuver buckets

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The bucket design enables one bucket to be placed inside another through the tapered floor configuration, creating a nested stacking arrangement. The tapered floor allows the upper bucket to rest securely within the lower bucket, eliminating the need for complex alternating stacking maneuvers and significantly reducing the time and space required for stacking operations.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of manufacture

If buckets are designed with traditional stacking configurations, then they can be stored and shipped, but they require significant space

Engineering Contradiction:

Improvestacking efficiencyVSAvoidstorage space

Core Design Contradiction:

Ease of manufactureVSVolume of stationary object

Solution Approach 1:

By enabling buckets to nest within one another through the tapered floor design, the overall volume required for storage is dramatically reduced. Multiple buckets can be compactly arranged in a vertical nested configuration, maximizing space utilization in storage facilities and reducing the number of shipping containers or trailers needed for transportation.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Productivity

If buckets have a tapered floor and parallel top wall sides, then they can be stacked efficiently, but the sides require a bend to connect both features

Engineering Contradiction:

Improvestacking speedVSAvoidside wall geometry

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The side walls incorporate a controlled bend or curvature to smoothly connect the tapered floor section with the parallel top wall sides. This curved transition maintains the structural integrity and stacking efficiency of the bucket while accommodating the geometric requirements of both the tapered floor and parallel top edges, enabling rapid stacking without compromising side wall strength.

Inventive Principle:

Principle #14Spheroidality (Curvature)

AI summary

A stackable bucket having a floor, a back wall, and two side walls has a tapered front to back floor but wherein the back wall is substantially rectangular. A diagonal bend allows each side plate to connect to the tapered floor and to the rectangular back wall. Gussets and double-ended reverse hooks may also be used to provide spacing between nested buckets.
