Solution Overview

Problem

Existing anti-theft cases require replacement of both the case and integrated closing device when the closing device malfunctions or needs to be changed, leading to additional expenses and inconvenience.

Innovation Solution

An interchangeable closing device with securing means that allows easy removal and replacement without compromising safety, compatible with various radio-frequency, electromagnetic, acoustic-magnetic systems, and magnetic uncoupling devices, which can be secured and unsecured using a detaching device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the anti-theft closing device is completely integrated in the case itself, then the safety characteristics are maintained, but the replacement cost increases when the closing device malfunctions or needs to be changed

Engineering Contradiction:
Improvesafety characteristicsVSAvoidreplacement cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The closing device is separated from the case body into an independent removable module. This segmentation allows the closing device to be replaced independently without replacing the entire case, reducing replacement costs while maintaining safety characteristics through the use of secure engagement features like bayonet mounts or screw connections.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closing device is extracted as a separate functional component from the integrated case structure. By providing dedicated securing means (such as mounting brackets, threads, or bayonet interfaces) on both the case and closing device, the design enables easy removal and replacement of the closing device while preserving the case's safety features.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the closing device is integrated in the case, then the structural integrity is maintained, but the adaptability decreases when needing to change detecting systems or uncoupling devices

Engineering Contradiction:
Improvestructural integrityVSAvoidsystem flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The closing device is divided into a replaceable module that can be independently exchanged. This allows different detecting systems (RF, EM, AM) and uncoupling devices to be adapted by simply replacing the closing device module while keeping the case structure intact, thus maintaining structural integrity while improving adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The case is designed with universal securing interfaces (such as standardized mounting features) that can accommodate different types of closing devices with various detecting systems and uncoupling mechanisms. This universal interface design enables the same case to support multiple system configurations, enhancing versatility without compromising structural integrity.

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

3Reliability

If the closing device is permanently integrated, then the safety system remains stable, but the ease of repair decreases when the closing device breaks or wears excessively

Engineering Contradiction:
Improvesafety system stabilityVSAvoidclosing device replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The closing device is designed as a separate replaceable module with dedicated securing means (such as bayonet mounts, threads, or snap-fit connections). This segmentation enables quick removal and replacement of the closing device when it breaks or wears, significantly improving ease of repair while maintaining safety system stability through consistent engagement features.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closing device is designed as a consumable component that can be easily discarded when worn or broken and replaced with a new or refurbished unit. The securing means are designed to facilitate quick removal without damaging the case or the replacement device, enabling efficient recovery and replacement cycles that maintain safety system reliability.

Inventive Principle:
Principle #34Discarding and recovering
