Solution Overview

Problem

Conventional packaging containers fail to quickly implement the effect of chemical agents on stored items, as the chemical agents take time to act, potentially leading to deterioration of the stored items due to oxygen exposure.

Innovation Solution

A packaging container design featuring a stored item containing part and a chemical agent containing part separated by an inner lid, with a ventilation path formed by a groove and recess on the inner wall, allowing for communication between the two parts and facilitating rapid action of the chemical agent.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the chemical agent and stored item are separated by an inner lid or diaphragm, then the stored item can be protected from direct contact with the chemical agent, but the chemical agent takes a longer period of time to have an effect on the stored item

Engineering Contradiction:
Improveprotection of stored itemVSAvoidtime for chemical agent to take effect
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The container is divided into a stored item containing part and a chemical agent containing part separated by an inner lid. The inner lid includes a ventilation path that allows controlled gas exchange between the two parts, enabling the chemical agent to gradually affect the stored item while maintaining separation and protection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ventilation path acts as an intermediary channel between the stored item containing part and the chemical agent containing part. It allows oxygen and other gases to pass through from the chemical agent side to the stored item side, enabling the chemical agent to exert its effect without direct contact between the two substances.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If the stored item is quickly exposed to the chemical agent, then the chemical agent can take effect rapidly, but the stored item may be damaged by direct contact with the chemical agent

Engineering Contradiction:
Improvespeed of chemical agent effectVSAvoiddamage from direct contact
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The container is segmented into two distinct parts: a stored item containing part and a chemical agent containing part, separated by an inner lid. This segmentation allows rapid gas exchange through the ventilation path while preventing direct contact between the stored item and chemical agent, thus achieving fast effect without damage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ventilation path serves as an intermediary mechanism that enables rapid gas exchange between the chemical agent and stored item environments. It allows oxygen to quickly pass through to where it is needed while the inner lid structure prevents harmful direct contact between the chemical agent and the stored item.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the chemical agent containing part and stored item containing part are integrated, then the structure is simpler, but the chemical agent cannot effectively protect the stored item without direct contact

Engineering Contradiction:
Improvestructural simplicityVSAvoidprotection effectiveness
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The inner lid integrates multiple functions: it separates the stored item and chemical agent containing parts while simultaneously providing a ventilation path for gas exchange. This merging of separation and communication functions into a single component achieves effective protection without requiring complex additional structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The inner lid serves multiple purposes: it acts as a separator between the two containing parts, provides structural support, and creates the ventilation path for gas exchange. This multi-functionality maintains structural simplicity while ensuring effective protection of the stored item through controlled chemical agent interaction.

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

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The packaging container enables quick application of the chemical agent's effect on the stored item, maintaining the item's quality by preventing direct contact and ensuring efficient absorption of oxygen and moisture through the ventilation path.

Implementation Method 1

a ventilation path in which the stored item containing part and the chemical agent containing part are in communication, the ventilation path being formed in an inner space defined by the first member and the second member

Methodology Applied
Scientific EffectDiffusion: Diffusion

Implementation Method 2

a groove including ends on both sides in a circumferential direction of a single face of an inner wall of the stored item containing part, formed in an approximately C shape connecting the ends, and disposed at a position at least partially facing the chemical agent containing part

Methodology Applied
Scientific EffectAbsorption: Absorption (physical)
