Solution Overview

Problem

Existing safety lock protection devices are vulnerable to attempts using magnetic means to force or drill into the lock, lacking adaptability and ease of use, and are not effectively secured against unauthorized access.

Innovation Solution

The protection device incorporates a blocking system with magnet pins that slide in a plane transverse to the axis of rotation, aligned with holes in the open/close member and blocking member, requiring a specific magnetic key interaction to enable displacement, preventing movement from the closed to open position, thus enhancing security and resistance to drilling attempts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If magnetic-coding means comprising magnets arranged according to a planar distribution are used, then the blocking system can be actuated by a magnetic key, but the device becomes vulnerable to attempts at forcing the lock using magnets

Engineering Contradiction:
Improveactuation by magnetic keyVSAvoidvulnerability to magnetic forcing attempts
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent transitions from a planar distribution of magnets to a three-dimensional arrangement where pins with magnets are distributed throughout a volumetric space. This spatial transformation from 2D to 3D configuration prevents unauthorized magnetic manipulation while preserving legitimate key actuation, as the magnetic field interaction requires precise positional alignment only achievable with the correct key.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent introduces pins with magnets as intermediary elements between the key and the blocking mechanism. These pins serve as magnetic mediators that transmit the magnetic field from the key to actuate the blocking system, while their specific positioning and magnetic properties create a selective response that rejects unauthorized magnetic forcing attempts.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If the blocking system uses a planar magnetic distribution, then the structure is simpler, but the resistance to drilling attempts is reduced

Engineering Contradiction:
Improvemagnetic coding structureVSAvoiddrilling attempts
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The patent distributes magnetic pins in a three-dimensional configuration rather than a flat planar arrangement. This volumetric distribution of magnetic elements throughout the blocking system's depth creates multiple layers of magnetic interaction points, making drilling attempts ineffective as the magnetic field cannot be compromised by surface-level penetration alone.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If magnets are arranged in a plane parallel to the front side, then the magnetic key interaction is straightforward, but the adaptability to various installation conditions is limited

Engineering Contradiction:
Improvemagnetic key interactionVSAvoidinstallation conditions adaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The three-dimensional pin distribution allows the magnetic field interaction to occur along multiple spatial dimensions, enabling the blocking system to adapt to various installation orientations and conditions while maintaining straightforward magnetic key operation. The volumetric arrangement of pins ensures consistent magnetic field geometry regardless of the device's mounting configuration.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
