Plastic Container Handle Grip Retainers for Stable Attachment

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing plastic handles for containers, such as paint buckets, lack optimal grip and retention mechanisms, leading to potential slippage and user discomfort, especially in varying environmental conditions.

Innovation Solution

A handle design featuring a grip with an elongated channel and a bail that slides into it, secured by retainers such as grooves and protrusions, providing stable attachment and user feedback on proper positioning, along with customizable features for comfort and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a simple bail design is used, then the handle structure is simple, but the grip stability is insufficient leading to potential slippage

Engineering Contradiction:

Improvegrip stabilityVSAvoidhandle structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The handle is divided into distinct functional segments: the bail component, the grip component, and the retention mechanism with protrusions and grooves. This segmentation allows each part to perform its specific function optimally while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The bail is inserted into and nested within the grip component, with the retention protrusions fitting into corresponding grooves. This nesting provides secure attachment without requiring complex fastening mechanisms

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a secure retention mechanism is added, then the handle attachment reliability improves, but the device complexity increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoidretention mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The retention mechanism operates automatically through the interaction of protrusions and grooves. When the bail is inserted into the grip, the protrusions naturally engage with the grooves to secure the attachment, requiring no additional user action or complex mechanisms

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The complex mechanical fastening systems are replaced with a simple geometric interlocking mechanism using protrusions and grooves. This substitution maintains high reliability while minimizing structural complexity

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If the bail is fully enclosed in the grip, then the attachment is secure, but the user cannot verify proper positioning

Engineering Contradiction:

Improveattachment securityVSAvoidposition verification

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The protrusions and grooves provide tactile feedback to the user during insertion. When the protrusions engage with the grooves, the user can feel a distinct click or stop, confirming proper positioning and secure attachment without needing visual inspection

Inventive Principle:

Principle #23Feedback

AI summary

The present disclosure relates to plastic handle for a container comprising a grip and a bail, wherein said bail comprises a first bail retainer and the grip comprises a first grip retainer that is adapted to mate with the first bail retainer such that, in use, corresponding retainers prevent sliding displacement of the grip with respect to the bail.
