Solution Overview

Problem

Existing methods for closing thin-walled transport containers for valuables, such as thermal sealing, gluing, mechanical closure, and latching systems, face issues like high energy consumption, maintenance requirements, limited automation, and vulnerability to manipulation, which compromise security and detection of unauthorized access.

Innovation Solution

A device featuring complementary latching elements that create a snap-in connection, with visible changes in shape upon separation, allowing for easy detection of manipulation attempts through visual inspection or mechanical scanning, and a uniaxial movement mechanism for secure and automated closure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If thermal sealing is used to close the thin-walled transport container, then the container is securely closed, but high energy consumption and thermal load occur which reduce service life and can damage valuables

Engineering Contradiction:
Improveclosure securityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces thermal sealing (thermal system) with a mechanical latching system consisting of closure elements with latching elements that engage to secure the container. This mechanical approach eliminates the need for heat energy while achieving secure closure, directly resolving the contradiction between closure security and energy consumption.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If thermal sealing is used to close the thin-walled transport container, then the container is securely closed, but high thermal load occurs which reduces service life of machine and valuables

Engineering Contradiction:
Improveclosure securityVSAvoidthermal load
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes the thermal sealing process with a mechanical latching mechanism where closure elements with latching elements engage to secure the container. This eliminates thermal load entirely while maintaining closure security, protecting both the machine and valuables from thermal damage.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If latching elements are used to create a latching connection, then secure closure is achieved, but manipulation can release and re-establish the connection making theft possible without immediate detection

Engineering Contradiction:
Improveclosure securityVSAvoiddetection of manipulation
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent incorporates visible indicators (such as color changes or shape changes) on the latching elements that permanently alter when the latching connection is separated. This allows immediate visual detection of manipulation attempts, preventing undetected theft while maintaining secure closure through the latching mechanism.

Inventive Principle:
Principle #32Color changes

AI summary

In a method and a device for closing at least one thin-walled transport container (12) for valuables, which has at least one opening, at least a part of the opening of the transport container (12), which is open for feeding the valuables, is arranged between a first closing element (14) comprising at least one locking element (18, 20) and a second closing element comprising at least one second locking element (22, 24) complementary to the first locking element (18, 20). The locking areas of the locking elements are designed such that at least two mutually complementary locking areas of the locking elements are configured such that one of these locking areas is visibly changed in shape when the locking connection is broken.
