Solution Overview

Problem

Existing container handle designs make it difficult for users to comfortably transport and empty containers due to the center of mass issue, leading to awkward mobility and inefficient disposal, especially with heavy or large containers.

Innovation Solution

A container design featuring a set of flanges with different attachment points for handles and a circumferential lip that allows users to grip the container at various locations, distributing the weight and facilitating easy transportation and emptying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a single handle is attached to the container at two opposing locations, then the handle provides a means for a user to grip and transport the container, but the user must grip the handle at the center of mass, experiencing the full weight of the container on one arm

Engineering Contradiction:
Improveease of transportVSAvoidweight strain on one arm
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The container is divided into multiple grip zones along its height, with the first grip zone positioned away from the center of mass. This segmentation allows users to select different grip locations based on their needs, specifically enabling them to grip above the center of mass to distribute weight more effectively.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention adds a vertical dimension to handle placement by providing multiple grip zones at different heights rather than a single horizontal handle. The first grip zone is positioned vertically above the center of mass, creating a new dimensional solution to the weight distribution problem.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Strength

If a supportive handle is built into the container body at a fixed location, then the handle provides structural support for gripping, but the user must grip this specific handle location to empty the contents, limiting maneuverability

Engineering Contradiction:
Improvestructural supportVSAvoidmaneuverability for emptying
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The container surface is segmented into multiple functional zones: a first grip zone for transport positioned away from the bottom, and a second grip zone near the bottom for emptying. This segmentation allows users to transition between different grip locations depending on the task, providing both structural support and maneuverability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handle system transitions from a fixed, static configuration to a dynamic system where the effective grip point can move between different zones. Users can dynamically select which grip zone to use based on whether they are transporting or emptying the container, adapting the system's functionality to the current task.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If traditional containers lack multiple handle-points, then the structure remains simple, but it is difficult for the user to maneuver the container while emptying contents and control the emptying process

Engineering Contradiction:
Improvestructural simplicityVSAvoidmaneuverability during emptying
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The container is segmented into distinct functional zones with different grip characteristics. The first grip zone provides a stable anchor point for transport, while the second grip zone near the bottom enables precise control during emptying. This segmentation adds minimal structural complexity while dramatically improving operational ease.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second grip zone acts as an intermediary element between the user and the container contents during emptying. By providing a dedicated grip point near the bottom, it mediates the emptying process, allowing users to control the flow of contents more effectively without requiring complex mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A container including a rigid base and one or more rigid lateral walls, the lateral wall being perimetrically continuous, such that the lateral wall and the base define a cavity. The cavity allows for the storage and transportation of contents, such as sand, rocks, building materials, paints, and other liquids. The container includes a set of flanges on an exterior side of the one or more lateral walls, with the flanges providing attachment points for a set of handles. When the set of handles are secured to the flanges, a user can easily grip the handles to transport the container to a new location. In addition, the container includes a circumferential lip that extends below the base, such that a user can easily grasp the lip at different locations to maneuver the container, without forcing the user to grip a specific handle on the bottom of the container.
