Solution Overview

Problem

Existing containers for holding food products lack efficient divider features that allow for separate compartments and easy assembly, leading to potential mixing of food items and difficulties in handling and erection.

Innovation Solution

A tray design featuring a plurality of panels and foldable end flaps that form a divider extending upwardly from the bottom panels, allowing for separate compartments and a simplified assembly process, optionally with locking features for stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If existing containers are used without divider features, then the container structure is simple, but food items may mix and compartments are not separated

Engineering Contradiction:
Improveproduct separationVSAvoidcontainer structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The container is divided into multiple compartments using divider panels that extend upwardly from the bottom panels. These dividers create separate interior spaces for different food items, achieving product separation while maintaining a relatively simple single-piece construction from the blank

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If traditional assembly methods are used, then the container can be formed, but assembly is difficult and handling is cumbersome

Engineering Contradiction:
Improveassembly processVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The blank is pre-designed with all panels, dividers, and flaps positioned and connected in their final assembly configuration before forming. The foldable end flaps are pre-attached to respective panels, allowing the container to be erected by simple folding and locking actions without complex assembly steps

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The container features self-locking mechanisms where the foldable end flaps automatically engage with the side panels to secure the container structure during erection. The divider panels are integrated into the blank and automatically position themselves to form the compartments without requiring separate assembly operations

Inventive Principle:
Principle #25Self-service
