Solution Overview

Problem

Existing security containers are vulnerable to explosive intrusive attacks, particularly gas explosions, and existing solutions require additional devices that increase costs and dimensions or reduce storage space.

Innovation Solution

A security container design with weakened areas in the side walls and reinforcing elements that allow for plastic deformation to absorb energy from explosions, maintaining the container's size and strength without additional devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If absorbing elements are installed on the internal walls to reduce explosion energy, then the explosion resistance is improved, but the storage space volume is reduced

Engineering Contradiction:

Improveexplosion resistanceVSAvoidstorage space volume

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent applies local quality by creating weakened areas at specific locations on the side walls rather than uniformly thickening all walls. These localized weakened zones allow controlled plastic deformation to absorb explosion energy while preserving the overall storage volume and external dimensions of the container.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent changes the structural parameter of the side walls by introducing weakened areas with reduced thickness or discontinuities. This parameter change enables the walls to undergo plastic deformation during explosion, absorbing energy through controlled deformation rather than rigid resistance, thus protecting the container without reducing storage space.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If a grille is installed in the interior behind the door to prevent access during explosion, then the security against intrusion is improved, but the storage space depth is reduced

Engineering Contradiction:

Improvesecurity against intrusionVSAvoidstorage space depth

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent converts the harmful effect of explosion into a beneficial protective mechanism. The weakened areas are designed to deform plastically under explosion pressure, absorbing energy and preventing the explosion from compromising the door or providing direct access to contents, thus turning the explosion's force into a protective barrier.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Strength

If the side walls are made thicker to resist explosion, then the strength is improved, but the external dimensions and material consumption increase

Engineering Contradiction:

Improveexplosion resistanceVSAvoidexternal dimensions

Core Design Contradiction:

StrengthVSLength of stationary object

Solution Approach 1:

Instead of uniformly thickening all side walls, the patent introduces localized weakened areas at specific positions. This allows the majority of the wall structure to maintain its original thickness and external dimensions, while the localized weakened zones provide the necessary energy absorption through controlled plastic deformation during explosion.

Inventive Principle:

Principle #3Local quality

4Reliability

If gas sensors and spark generators are installed to detect and trigger controlled explosion, then the prevention of considerable impact is improved, but the device complexity and maintenance requirements increase

Engineering Contradiction:

Improveprevention of considerable impactVSAvoidadditional equipment

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent eliminates the need for active detection and control systems by designing the container structure itself to passively absorb explosion energy. The weakened areas in the side walls are engineered to deform plastically under explosion pressure, converting the harmful explosion energy into beneficial structural deformation that protects the container without requiring sensors, spark generators, or maintenance.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

Security container, such as safe, treasure-chest, security cabinet or strongbox, resistant to explosive intrusive attacks, especially attacks with explosive gas, comprising a housing (2) and a door (3). The housing consists of walls formed by an inner (10) and an outer side (11), between which at least one reinforcing element (12, 13) is arranged. On the inner (10) and/or the outer side (11) of each side wall (5, 6) at least one weakened area (14, 15) of the side (10, 11) is formed. A weakened area (16, 17) is also formed on at least one reinforcing element (12, 13). Each of the contact edges of the two inner sides (10) of the side walls (5, 6) with the inner side of the lower (4) and the upper wall (8) of the security container (1) is externally reinforced with at least one reinforcing element (18).
