Solution Overview

Problem

Conventional dual-purpose containers for shipping and displaying products often suffer from structural and functional shortcomings, such as inadequate stacking strength and complexity in manufacturing.

Innovation Solution

The development of corrugated paperboard containers with specific fold lines, cut lines, and adhesive application methods to create containers with enhanced structural integrity and simplified manufacturing processes, allowing for improved stacking strength and easy conversion between shipping and display modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional containers are designed for dual-purpose shipping and displaying, then versatility is improved, but structural integrity and stacking strength deteriorate

Engineering Contradiction:
Improvedual-purpose capabilityVSAvoidstacking strength
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The container is divided into multiple walls (first wall, second wall, third wall, fourth wall) that can be independently configured and assembled. This segmentation allows the container to be designed with specific structural reinforcements in shipping mode while maintaining display capabilities through the same modular structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The container incorporates movable or reconfigurable elements that allow it to transition between shipping and display configurations. The walls and panels can be adjusted, repositioned, or reconfigured to optimize structural strength for shipping and then adapted for display purposes, maintaining both versatility and strength throughout the transformation.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If conventional containers are designed for dual-purpose shipping and displaying, then versatility is improved, but manufacturing complexity deteriorates

Engineering Contradiction:
Improvedual-purpose capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The container design incorporates universal components and standardized connection methods that enable the same structure to serve both shipping and display functions. By using standardized panels, walls, and assembly procedures, the manufacturing process remains simple and efficient while achieving dual-purpose capability without increasing complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of manufacture

If conventional containers use traditional construction methods, then ease of manufacture is maintained, but structural integrity deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidstructural integrity
Core Design Contradiction:
Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The container walls and panels are pre-formed, pre-assembled, or pre-configured in specific patterns and structures before final assembly. This preliminary action allows for optimized structural integrity to be built into each component during manufacturing, while the overall assembly process remains simple and efficient using standardized connection methods.

Inventive Principle:
Principle #10Preliminary action
