Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Large refuse containers require excessive effort to repeatedly place items due to the need for complete lid removal and do not allow convenient side-laying for debris collection.

Innovation Solution

A container assembly with a lid featuring a door that can be opened and closed, allowing partial access without removing the entire lid, and a design that enables the container to be laid on its side for sweeping or blowing debris, with ergonomic handles and a corrugated rear wall for added strength and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a large lid is used to cover the container opening, then the container can be effectively enclosed, but the effort required to remove and replace the lid increases significantly

Engineering Contradiction:

Improveenclosure effectivenessVSAvoidlid handling effort

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The lid is segmented into a main lid body and a separate door portion. The door can be opened independently to access the container interior without removing the entire lid, while the main lid body remains attached and provides continuous enclosure. This segmentation allows users to perform frequent access operations with minimal effort while maintaining effective enclosure when the door is closed.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If a large opening is provided in the lid for inserting garbage bags, then items can be easily inserted, but the lid cannot provide adequate protection when not in use

Engineering Contradiction:

Improveitem insertion easeVSAvoidprotection effectiveness

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The door is designed to be dynamically openable and closable, allowing the lid to adapt between two states: open for easy item insertion and closing for adequate protection. The door's movable nature enables users to open it wide for inserting garbage bags and items, then close it to provide protection against pests, weather, and contamination, thus resolving the contradiction between accessibility and protection.

Inventive Principle:

Principle #15Dynamics

3Stability of the object's composition

If the container has a fixed upright position, then it provides stable storage, but it cannot be used for sweeping or blowing debris into

Engineering Contradiction:

Improvestorage stabilityVSAvoidusage flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The container is designed with universal functionality to serve multiple purposes: it can be positioned upright for stable storage and transport, or laid on its side for sweeping or blowing debris into. The lid with its door mechanism works effectively in both orientations, allowing the container to adapt to different operational modes without requiring separate devices, thus achieving both stability and versatility.

Inventive Principle:

Principle #6Universality (Multi-functionality)
