Solution Overview

Problem

The packaging industry faces challenges in creating environmentally friendly packaging for fruits, berries, and vegetables that balances ventilation, moisture resistance, stackability, visibility, and secure access while maintaining production costs, as traditional plastic solutions are detrimental to the environment and fail to meet consumer needs for easy access and product freshness.

Innovation Solution

A cardboard packaging box design featuring a pour opening with tamper-evident perforated lines, ventilation recesses, transparent or mesh windows for visibility, and a foldable bottom with supporting legs for stackability and ventilation, ensuring the product remains fresh and secure until purchase.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If plastic packaging is used, then production cost is low and manufacturing is easy, but environmental harm increases and consumer perception deteriorates

Engineering Contradiction:

Improveease of productionVSAvoidenvironmental harm

Core Design Contradiction:

Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from plastic to cardboard, transforming the packaging from non-biodegradable to environmentally friendly while maintaining manufacturability through standard cardboard cutting and folding processes

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent uses composite construction with cardboard as the base material, enhanced with perforated patterns for ventilation and moisture control, creating a multi-functional packaging solution that addresses both environmental concerns and product preservation needs

Inventive Principle:

Principle #40Composite materials

2Object-generated harmful factors

If cardboard material is used, then environmental friendliness improves, but moisture resistance and strength deteriorate

Engineering Contradiction:

Improveenvironmental friendlinessVSAvoidmoisture resistance

Core Design Contradiction:

Object-generated harmful factorsVSStrength

Solution Approach 1:

The patent incorporates perforated patterns in the cardboard packaging that serve dual functions: enabling ventilation to prevent moisture buildup and maintaining structural integrity through strategic placement and sizing of perforations

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

The perforated patterns act as intermediaries that regulate moisture and air flow between the packaged produce and the external environment, preventing excessive moisture accumulation while maintaining cardboard strength

Inventive Principle:

Principle #24Intermediary (Mediator)

3Loss of information

If transparent packaging is used, then product visibility improves, but security and tamper evidence deteriorate

Engineering Contradiction:

Improveproduct visibilityVSAvoidsecurity

Core Design Contradiction:

Loss of informationVSReliability

Solution Approach 1:

The patent uses transparent or translucent windows in the cardboard packaging that allow consumers to view the product while maintaining the overall opaque and secure structure of the cardboard box, combining visibility with tamper evidence

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The packaging is segmented into transparent window sections and opaque cardboard sections, allowing selective transparency where needed for product display while maintaining security in other areas through the tamper-evident cardboard structure

Inventive Principle:

Principle #1Segmentation

4Reliability

If sealed packaging is used, then product security improves, but consumer access and ease of use deteriorate

Engineering Contradiction:

Improveproduct securityVSAvoidconsumer access

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent pre-creates perforated opening lines in the cardboard packaging during manufacturing, enabling consumers to easily tear open the package along predetermined paths without requiring tools or excessive force, thus maintaining security until opening while ensuring ease of access

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The packaging transitions from a sealed secure state to an easily openable state through pre-scored perforations that guide the opening action, allowing dynamic conversion between security and accessibility based on consumer need

Inventive Principle:

Principle #15Dynamics

5Reliability

If ventilation openings are added, then product freshness improves, but structural strength and stackability deteriorate

Engineering Contradiction:

Improveproduct freshnessVSAvoidstackability

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The patent uses perforated cardboard patterns that provide adequate ventilation for produce freshness while maintaining structural strength through optimized perforation size, shape, and distribution that preserves the cardboard's load-bearing capacity

Inventive Principle:

Principle #31Porous materials

Solution Approach 2:

Ventilation perforations are strategically placed in specific locations where they provide maximum airflow benefit without compromising structural integrity, such as in non-load-bearing areas or distributed in patterns that maintain overall strength

Inventive Principle:

Principle #3Local quality
