Solution Overview

Problem

Security containers, such as those used for transporting and replenishing bank notes in ATMs, are vulnerable to theft during transit, and existing solutions do not adequately delay access to the contents or ensure timely activation of spoiling systems to render stolen items unusable.

Innovation Solution

A security container design featuring a dual locking mechanism where the second locking mechanism can only be disengaged after the first is unlocked, with a spoiling system actuated by a pressurized gas container that locks the second mechanism in place upon unauthorized access, delaying access and ensuring contents are marked and rendered unusable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single locking mechanism is used, then the container can be opened quickly, but the security against theft during transit is insufficient

Engineering Contradiction:
Improvesecurity against theftVSAvoidlocking mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is divided into two distinct stages: a first locking mechanism that secures the lid in a closed position, and a second locking mechanism that becomes accessible only after the first is disengaged. This segmentation provides layered security while maintaining operational clarity, as each mechanism performs a specific function in sequence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first locking mechanism must be disengaged before the second locking mechanism becomes accessible. This preliminary action ensures that authorized users follow a specific sequence, while unauthorized users attempting to bypass the first mechanism will not gain access to the second, thereby enhancing security without requiring simultaneous complex operations.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the lid is made fully movable for easy access, then contents can be quickly retrieved, but the delay needed for spoiling system activation is lost

Engineering Contradiction:
Improvespoiling system activation timingVSAvoidlid accessibility
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The lid transitions from a fully fixed position to a partially movable position. When the first locking mechanism is disengaged, the lid becomes movable to a limited extent, allowing the second locking mechanism to be accessed while still maintaining restriction. This dynamic state provides the necessary delay for spoiling system activation while enabling authorized access progression.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The second locking mechanism acts as an intermediary between the first locking mechanism and full lid removal. It provides an intermediate security layer that must be disengaged after the first mechanism, creating a controlled transition state that delays full access and allows time for security systems to respond.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the second locking mechanism is always accessible, then quick access is possible, but security against unauthorized access is compromised

Engineering Contradiction:
Improveunauthorized access preventionVSAvoidaccess sequence complexity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The first locking mechanism must be disengaged as a preliminary action before the second locking mechanism becomes accessible. This sequence ensures that unauthorized users cannot directly access the second mechanism, while authorized users follow a defined process that enhances security without creating unnecessary complexity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The accessibility of the second locking mechanism is locally controlled - it becomes accessible only in the specific condition where the first locking mechanism has been disengaged. This localized accessibility change provides enhanced security for the second mechanism while maintaining ease of operation for authorized users who have already completed the first step.

Inventive Principle:
Principle #3Local quality

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The dual locking mechanism provides additional security by delaying access and the spoiling system effectively renders stolen contents worthless, enhancing the security of the container and deterring theft by ensuring that the contents are marked and unusable upon unauthorized attempts.

AI summary

A security container (10) comprises a base (12), a lid (14) configured to fit onto the base (12), and first and second locking mechanisms (18,28) engageable to secure the lid (14) to the base (12). Means for disengaging the second securing mechanism (28) is accessible only once the first securing mechanism (18) has been disengaged.
