Solution Overview

Problem

Existing product packaging containers lack optimal rigidity for efficient stacking and storage, leading to deterioration and inefficiencies in logistics, while overly rigid containers increase weight and manufacturing costs.

Innovation Solution

A container configuration from an extended flat sheet with specific folding and attachment of elements, including flanges and assembly flaps, creates a rigid structure that allows for aligned stacking and improved storage logistics while maintaining product protection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If containers are made rigid to withstand product weight and stacking stresses, then stacking stability and product protection are improved, but container weight and manufacturing cost increase

Engineering Contradiction:
Improvecontainer rigidityVSAvoidcontainer weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The container is divided into multiple walls (front walls, lateral walls, lower wall) that are folded and attached to form a rigid three-dimensional structure from a flat sheet. This segmentation allows the structure to gain rigidity through geometric configuration rather than using heavier material.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flanges are positioned specifically at the upper portions of the front and lateral walls, providing localized reinforcement exactly where stacking stresses are applied. This targeted reinforcement achieves the necessary rigidity for stacking without requiring the entire container structure to be overly rigid or heavy.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If containers are made rigid to withstand stacking stresses, then stacking stability is improved, but manufacturing complexity and material volume increase

Engineering Contradiction:
Improvestacking stabilityVSAvoidcontainer structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The container structure is segmented into distinct walls (front, lateral, lower) that are folded and attached together. This modular segmentation simplifies the manufacturing process by allowing each component to be formed and assembled separately, reducing overall structural complexity while maintaining stacking stability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

By concentrating reinforcement elements (flanges) only at specific locations where stacking stresses occur, rather than making the entire container structure complex and heavy, the design achieves stacking stability with minimal added complexity to the overall structure.

Inventive Principle:
Principle #3Local quality

3Reliability

If containers are made rigid to protect products, then product protection is improved, but container volume and material consumption increase

Engineering Contradiction:
Improveproduct protectionVSAvoidcontainer volume
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The container is constructed from segmented walls folded into a three-dimensional configuration, which provides structural integrity and product protection through geometric strength rather than requiring excessive material volume. The segmented approach allows for efficient use of material while maintaining protective capabilities.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flanges provide localized structural reinforcement at critical points (upper portions of walls) to protect products during stacking, rather than increasing the overall container volume. This targeted reinforcement ensures product protection with minimal additional material consumption.

Inventive Principle:
Principle #3Local quality
