Solution Overview

Problem

Existing containment systems for liquid chemicals in manufacturing processes lack effective identification and secure dispensing mechanisms, risking contamination and improper fluid usage, especially in clean room environments where incorrect fluids can lead to damage or contamination.

Innovation Solution

A cap and closure system featuring a key code body with a shoulder and a removable closure member, which includes engagement surfaces and a sealing mechanism to securely seal the container and prevent accidental fluid release, ensuring proper fluid identification and safe dispensing through alignment with specific dispensing devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a simple cap is used for fluid containers, then the device complexity is reduced, but the reliability of fluid identification and secure dispensing deteriorates

Engineering Contradiction:

Improvecap structureVSAvoidfluid identification and secure dispensing

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The cap is divided into distinct functional segments: a cap body for basic closure, a key code body for identification, and a removable closure member for secure sealing. Each segment performs a specific function, allowing the system to achieve high reliability through modular design while keeping individual components relatively simple.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The key code body is nested within the cap body, and the removable closure member is nested within the key code body. This nested arrangement integrates multiple functions (identification, sealing, and secure closure) into a compact structure without significantly increasing overall device complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a removable closure member with engagement surfaces is added, then the reliability of preventing accidental fluid release is improved, but the device complexity increases

Engineering Contradiction:

Improveprevention of accidental fluid releaseVSAvoidclosure system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The removable closure member is pre-configured with engagement surfaces that must align with corresponding features on the key code body. This preliminary design ensures that proper alignment and intentional action are required for opening, preventing accidental fluid release while maintaining a relatively simple closure mechanism.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The engagement surfaces act as an intermediary mechanism between the closure member and the key code body. This intermediary structure provides a simple yet effective locking mechanism that enhances reliability without requiring complex components or mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a key code body with engagement structure is incorporated, then the reliability of secure sealing is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvesecure sealingVSAvoidopening and closing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The sealing function is segmented into the engagement structure on the key code body and the corresponding engagement surfaces on the closure member. This segmentation allows the sealing mechanism to be independent and simple, improving reliability while maintaining ease of operation through straightforward engagement and disengagement actions.

Inventive Principle:

Principle #1Segmentation

4Reliability

If multiple engagement structures are added for secure closure, then the reliability of containment is improved, but the device complexity increases

Engineering Contradiction:

Improvecontainment securityVSAvoidengagement structures

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Multiple engagement structures (threads between cap body and container, engagement structure between key code body and cap body, and engagement surfaces between closure member and key code body) are merged into a single integrated closure system. This merging achieves high containment security through cumulative engagement points while avoiding the complexity of separate, independent locking mechanisms.

Inventive Principle:

Principle #5Merging (Combining)
