Solution Overview

Problem

Existing devices for situation-related authorized access to housings, such as containers, face a contradiction between ensuring immediate access in emergency situations while preventing theft, as key systems lack a sufficient protection threshold and open systems are not secure against unauthorized access or restoration of contents.

Innovation Solution

A device with a smashable glass barrier that, upon destruction, allows access to the locking mechanism, providing a psychological and physical inhibition threshold, and utilizing the same mechanism for both unlocking and locking, ensuring that access is only possible after complete destruction of the barrier, which also serves as an alarm trigger.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a key system is used for authorized access, then service access is controlled, but access in emergency situations is not guaranteed

Engineering Contradiction:
Improveaccess in emergency situationsVSAvoidprotection against theft
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The access system is segmented into two independent paths: a normal access path requiring key operation, and an emergency access path requiring barrier destruction. This segmentation allows the system to provide different access conditions for different situations, ensuring both security and emergency accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The breakable barrier serves as an intermediary element between the user and the locking mechanism. In normal conditions, the barrier provides psychological deterrence; in emergency conditions, its destruction mediates immediate access without requiring key operation, thus resolving the contradiction between security and emergency access.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If an open system with mechanical or electromechanical locking is used, then access is easily achievable, but protection against theft is insufficient

Engineering Contradiction:
Improveaccess easeVSAvoidanti-theft protection threshold
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The breakable barrier provides preliminary anti-action by creating a psychological and physical inhibition threshold before access is granted. The mere presence of the barrier deters potential thieves, while in genuine emergencies, its destruction enables access. This preliminary protective measure raises the anti-theft threshold without significantly impeding legitimate access.

Inventive Principle:
Principle #9Preliminary anti-action

3Ease of operation

If a breakable barrier is added for emergency access, then emergency access is enabled, but device complexity increases

Engineering Contradiction:
Improveemergency accessVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The barrier is designed as a simple, replaceable component that can be easily destroyed in emergencies. Using a simple breakable barrier rather than a complex electronic system reduces overall device complexity while maintaining the emergency access function. The barrier acts as a disposable protective element that serves its purpose and can be replaced.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If the locking mechanism is made more secure, then anti-theft protection is improved, but service access may be restricted

Engineering Contradiction:
Improveanti-theft protectionVSAvoidservice access
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically adapts its access requirements based on the situation. For normal service access, the key-operated locking mechanism provides secure controlled access. For emergency situations, the system allows alternative access through barrier destruction. This dynamic behavior resolves the contradiction between security and accessibility.

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a device for the situation-dependent authorised admission or access to any casing, in addition to the protection of said casing against misuse of the content. Said device comprises at least one opening/closing mechanism (1) and at least one locking/unlocking mechanism (2) which can be engaged or disengaged and/or actuated by the opening/closing mechanism (1). Said invention is characterised by the fact that in the access area of one or more locking/unlocking mechanisms (2), the casing is provided with at least one barrier (3) which can be overridden by means of at least one mechanical and/or electromechanical protector or covering which can be actuated manually, the irreversible deformation/destruction of said barrier nonetheless providing access to a locking/unlocking mechanism (2).
