Solution Overview

Problem

Lids and shelves in containers for transporting dry goods are often misplaced, leading to inefficiencies in logistics due to the time required to retrieve them during loading and unloading operations.

Innovation Solution

A container system with a detachable lid featuring inwardly projecting T-shaped attachments that fit into corresponding receivers on the container side wall, allowing the lid to be rested on the side wall without obstructing operations, and a method for securing removable shelves using shelf locators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the lid is removed from the container, then the container body can be collapsed for efficient reverse logistics, but the lid becomes misplaced and causes time loss during loading/unloading operations

Engineering Contradiction:

Improvelogistics efficiencyVSAvoidtime to retrieve lid

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The lid is attached to the container side wall in advance through the lid attachment and lid receiver mechanism, so that when the container body is collapsed, the lid is already positioned and secured, eliminating the need to search for it during subsequent loading/unloading operations

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The lid attachment and lid receiver act as an intermediary mechanism that connects the lid to the container side wall, providing a dedicated resting position for the lid during the collapsed state while preventing it from becoming misplaced

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the lid is placed over the collapsed container body, then it is ready for transportation, but it may become misplaced during handling

Engineering Contradiction:

Improvecontainer preparationVSAvoidlid positioning

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The lid is extracted from the container opening and secured to the side wall through the attachment mechanism, separating the lid's storage function from the container body while ensuring it remains securely positioned and cannot become misplaced during handling

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The lid receiver on the side wall acts as an intermediary structure that receives and secures the lid attachment, providing a reliable and dedicated positioning mechanism that prevents the lid from becoming misplaced during container handling and transportation

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

There is disclosed a container of the Large Foldable Container (or “LFC”) type comprising a detachable lid and a container side wall. The detachable lid comprises at least one lid attachment that projects inwardly from an underside of the lid. The container side wall comprises at least one corresponding lid receiver for receiving said lid attachment. The at least one lid attachment and corresponding lid receiver are configured such that the lid can be rested by a user on the container side wall by accommodating said at least one lid attachment within said at least one corresponding lid receiver, such that at least a majority and, in most cases, all of the lid underside faces the outer face of the container side wall. In such manner, the detachable lid can be easily and conveniently rested on the container side wall, while access to the enclosable volume of the container is not impaired.
