Garbage Bin With Recessed Wheels And Pivoting Handles

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing garbage bins face issues with navigation due to outwardly set wheels, improper closure leading to odor emission, and are either too large and heavy for manual movement or lack handles for ease of use.

Innovation Solution

A garbage bin design featuring recessed wheels for easy navigation, pivoting handles for balance, a bottom opening for access, an accordion door for odor containment, and a lid section with latches to allow taller refuse and easier lifting, ensuring stability and odor prevention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wheels are set outwardly from the bottom of the garbage bin, then the bin can be moved, but the wheels catch on various objects and doorways during transport

Engineering Contradiction:

Improveease of movementVSAvoidnavigation reliability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent inverts the conventional wheel placement by recessing the wheels inwardly into the bottom surface of the bin rather than protruding outward. This inversion prevents wheels from catching on objects and doorways during transport while maintaining mobility functionality.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The wheels are nested within recesses in the bottom surface of the bin, allowing them to be contained within the bin's footprint when not in use, preventing interference with surrounding objects while remaining accessible for movement.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of stationary object

If the garbage bin is made large to accommodate more refuse, then capacity increases, but the bin becomes heavy and impossible to move without a truck or machine

Engineering Contradiction:

Improvegarbage capacityVSAvoidbin weight

Core Design Contradiction:

Volume of stationary objectVSWeight of moving object

Solution Approach 1:

The patent introduces pivoting handles that can rotate between a stored position and an extended position, allowing the bin to transition from a compact heavy object to a manageable leveraged tool, enabling manual movement of larger capacity bins.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent adds the dimensional aspect of handle extension and pivoting motion, transforming the interaction from direct lifting to leveraged pulling/pushing, effectively reducing the perceived weight and effort required to move the bin.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Ease of operation

If the garbage bin is made compact for easy movement, then mobility improves, but it cannot accommodate taller refuse items

Engineering Contradiction:

Improveease of movementVSAvoidheight capacity

Core Design Contradiction:

Ease of operationVSLength of moving object

Solution Approach 1:

The pivoting handle mechanism allows the bin to maintain a compact form factor for mobility while dynamically extending the effective handling length when needed, enabling both tall item accommodation and easy movement.

Inventive Principle:

Principle #15Dynamics

4Ease of operation

If the garbage bin uses a simple open top design, then access is easy, but refuse fumes are not contained and attract various animals

Engineering Contradiction:

Improveaccess easeVSAvoidodor emission

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs an accordion door with flexible collapsible panels that can be slid open for access and closed for containment, providing both easy access and effective odor/animal prevention through the flexible barrier.

Inventive Principle:

Principle #30Flexible shells and thin films

5Object-affected harmful factors

If the garbage bin uses a latch mechanism to close and prevent odors, then odor containment improves, but the bin becomes very large, heavy, and impossible to move

Engineering Contradiction:

Improveodor containmentVSAvoidbin weight

Core Design Contradiction:

Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The patent combines the latch mechanism with pivoting handles and recessed wheels, creating a dynamic system where the bin can be securely closed for odor containment yet easily maneuvered when needed through mechanical advantage and reduced friction.

Inventive Principle:

Principle #15Dynamics

6Device complexity

If the garbage bin lacks handles, then the structure is simpler, but users cannot easily move or balance the bin

Engineering Contradiction:

Improvestructural simplicityVSAvoidhandling ease

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The pivoting handle provides dynamic functionality, allowing the handle to be stored flush with the bin body for simplicity and extended to a convenient length for easy handling and balancing, achieving both structural simplicity and operational ease.

Inventive Principle:

Principle #15Dynamics

AI summary

The garbage bin device provides a lid section that can be totally unlatched from the bottom section, along with an overlap of the bottom section to avoid closing difficulties and to limit odor emanation. Pivoting handles are positioned to provide for balancing the device. A bottom opening with accordion door and t-handle operation provides for emptying the bin device as desired, whether through lid top or bottom side. A gable and arched top also provide for additional clearance for taller items. An indicia is provided for the lid section lid front, whether user or distributor supplied. A rear top overlap further protects against odor emanation. Latches assist in preventing animal invasion.
