Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing methods for resisting rotation of mixing containers, such as buckets, during mixing operations are unsafe, inefficient, and require special-purpose buckets or cumbersome user positioning, posing risks of chemical spills and user injury.

Innovation Solution

A tool with a handle engaging portion and a step plate configured at right angles, allowing the tool to be attached to a bucket handle and rested on the ground, providing stability during mixing, and featuring a hinged design for storage and lid prying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the user positions the bucket between their two legs and pinches the bucket, then the bucket rotation is resisted, but the user safety is compromised

Engineering Contradiction:

Improvebucket stabilityVSAvoiduser safety

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The tool acts as an intermediary device between the user and the bucket. Instead of the user directly contacting the bucket with their legs (harmful), the tool engages the handle and provides a safe interface. The step plate transfers the user's weight to the ground while the handle engaging portion resists bucket rotation, eliminating direct harmful contact between the user's body and the rotating bucket.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If the bucket is placed into a recessed holder on the floor, then the bucket rotation is resisted, but the operation complexity increases due to lifting and repositioning

Engineering Contradiction:

Improvebucket stabilityVSAvoidoperation simplicity

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The tool enables the bucket to essentially stabilize itself during mixing. The handle engaging portion attaches to the bucket handle, and the step plate rests on the ground, creating a self-supporting structure. The user simply steps on the plate during mixing, and the system automatically resists rotation without requiring the user to lift, reposition, or manually hold the bucket in place.

Inventive Principle:

Principle #25Self-service

3Stability of the object's composition

If a prefabricated bucket with an aperture for receiving a user's foot is used, then the bucket rotation is resisted, but the user injury risk increases due to ankle twisting

Engineering Contradiction:

Improvebucket stabilityVSAvoiduser injury risk

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The stabilization function is segmented into two separate components: the handle engaging portion that attaches to the bucket handle, and the step plate that provides foot support. This segmentation allows the foot support to be positioned on the ground away from the bucket, eliminating the risk of ankle twisting that would occur if the foot were inserted into an aperture in the bucket itself.

Inventive Principle:

Principle #1Segmentation

4Stability of the object's composition

If a special purpose bucket is used, then the bucket rotation is resisted, but the device complexity and cost increase

Engineering Contradiction:

Improvebucket stabilityVSAvoidbucket design simplicity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The tool is designed to attach to standard bucket handles and work with conventional mixing buckets, making it universally applicable. The handle engaging portion can accommodate various handle configurations, and the step plate provides generic foot support. This universality means users don't need to purchase special purpose buckets; they can use their existing buckets with this attachment tool.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A tool for resisting rotation of a bucket of the type having a handle carried on a support wire is provided. The tool includes a handle engaging portion configured for attaching or engaging with the handle of the bucket, and a step plate coupled with the handle engaging portion and configured for resting against a surface of the ground. The handle engaging portion and the step engaging portion are configured to extend at generally right angles from each other. In operation, the handle engaging portion is engaged with the handle of the bucket, and the step plate is positioned on the ground, and a user steps on the step plate during mixing of materials contained within the bucket.
