Solution Overview

Problem

Existing closure arrangements often require tools for connection and disconnection, provide insufficient closure force, are not flexible, and may require complex movement sequences, leading to inefficiencies and increased part counts for multiple functionalities.

Innovation Solution

A closure arrangement featuring a reversible locking mechanism that enables positive locking between components, allowing for secure connection and flexible latching depths without tools, using form restraints and interlocking mechanisms for quick assembly and disassembly, and optionally incorporating elastic elements for repeated use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If a closure arrangement uses tools for connection and disconnection, then the closure force can be high, but the time required for closing or opening increases significantly

Engineering Contradiction:
Improveclosure forceVSAvoidtime required for closing or opening
Core Design Contradiction:
ForceVSLoss of time

Solution Approach 1:

The closure arrangement is divided into two independent functional elements: a closure element that provides form locking with high closure force, and a separate locking mechanism that prevents opening. This segmentation allows the closure to achieve high force without requiring tools for the opening prevention function, reducing overall operation time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines the closure function (form locking) and the locking function (opening prevention) into a single integrated closure arrangement. The locking mechanism is positioned between the closure surfaces and works together with the form locking to provide both high closure force and tool-free operation.

Inventive Principle:
Principle #5Merging (Combining)

2Loss of time

If a closure arrangement allows tool-less opening, then the operation time is reduced, but the closure force becomes insufficient

Engineering Contradiction:
Improveoperation timeVSAvoidclosure force
Core Design Contradiction:
Loss of timeVSForce

Solution Approach 1:

The closure arrangement separates the closure function (handled by the closure element with form locking) from the locking function (handled by the dedicated locking mechanism). This allows the closure element to provide sufficient closure force through form locking while the locking mechanism prevents opening without requiring tools, thus maintaining both high force and quick operation.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If a closure arrangement uses a firm stop like snap hooks or rivets, then the connection is secure, but flexibility for changing conditions is lost

Engineering Contradiction:
Improveconnection securityVSAvoidflexibility for changing conditions
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The locking mechanism is designed to be reversible and adjustable, allowing the closure arrangement to adapt to different conditions. The locking element can be positioned at different locations along the locking path, enabling flexible adjustment of the locking depth and position while maintaining secure connection when locked.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If a closure arrangement uses a flexible stop like a cable tie, then adaptability to changing conditions is improved, but the locking force increases with greater overlap making constant closing force impossible

Engineering Contradiction:
ImproveflexibilityVSAvoidlocking force consistency
Core Design Contradiction:
Adaptability or versatilityVSForce

Solution Approach 1:

The locking mechanism uses a locking element that can be positioned at different locations along a defined locking path, changing the positional parameter to achieve different locking depths. This allows flexible adaptation while maintaining consistent locking force through the mechanical geometry of the locking element and its interaction with the locking surface.

Inventive Principle:
Principle #35Parameter changes

5Adaptability or versatility

If multiple components are used to fulfill different required tasks, then all functions are achieved, but the device complexity and part count increase

Engineering Contradiction:
Improvemultiple integrated functionalityVSAvoidnumber of parts
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The closure arrangement integrates multiple functions into a single system: the closure element provides form locking and closure force, while the locking mechanism provides opening prevention and reversible locking. This multi-functionality eliminates the need for separate components for each function, reducing part count and overall device complexity.

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