Solution Overview

Problem

Existing wheelie bins are unsanitary as users often touch the handles directly, leading to contamination from viruses and bacteria.

Innovation Solution

An extension grip for the wheelie bin handle featuring a clamp mechanism that secures the handle without direct hand contact, including a U-shaped frame, fixed and moving grips, and a hook for lifting lids and carrying bins/bags.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users grab the wheelie bin handle directly to move the bin, then ease of operation is improved, but hands become contaminated with viruses and bacteria

Engineering Contradiction:

Improveease of moving binVSAvoidhand contamination

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The extension grip acts as an intermediary device between the user's hand and the bin handle. It includes a clamp mechanism that secures to the bin handle and an extension bar that extends outward, allowing users to grip the extension bar instead of the actual bin handle, thus preventing direct contact with contaminated surfaces

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If an extension grip with clamp mechanism is added to the wheelie bin handle, then hand sanitation is improved, but device complexity increases

Engineering Contradiction:

Improvehand contaminationVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The extension grip is divided into distinct functional segments: a clamp mechanism for securing to the bin handle, an extension bar for gripping, and release functionality. This segmentation allows each component to perform its specific function efficiently while maintaining overall simplicity

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The clamp mechanism is designed to be self-securing through a lever action that automatically clamps onto the bin handle when engaged, and self-releasing when the lever is actuated. This eliminates the need for additional fasteners, tools, or complex assembly mechanisms

Inventive Principle:

Principle #25Self-service

3Reliability

If a clamp mechanism is used to secure the extension grip to the bin handle, then grip security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvegrip securityVSAvoidease of attachment

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clamp mechanism transitions from a static secured state to a dynamic adjustable state through lever action. The lever allows the clamp to be quickly opened and closed, providing secure attachment when needed while maintaining ease of operation through simple mechanical movement

Inventive Principle:

Principle #15Dynamics

AI summary

The present invention provides innovative extension grips for the wheelie bin handle to keep your hands clean and free of contamination. The extension grip comprises a frame, a fixed handle, a pull handle, a clamp, a hook, and a connecting rod connecting the pull handle with the clamp. When a user squeezes a lever of pull handle of the extension grip, the clamp will close, providing the user with a secure grip of the wheelie handle. After moving the wheelie bin to the desired location, the user releases the lever of pull handle, the clamp will open.
