Solution Overview

Problem

Current self-locking anti-panic locks with a panic function are limited to either a left or right orientation, requiring a separate variant for each direction, making subsequent conversion impossible after installation.

Innovation Solution

A self-locking anti-panic lock design featuring a slidably mounted cuboid magnet within a magnetic rocker, allowing for adjustable panic function direction using a simple tool from the outside, eliminating the need for multiple variants by utilizing a channel with steel stops to secure the magnet's position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed magnet position is used in the magnetic rocker, then the lock provides reliable locking function, but it requires separate variants for left and right panic directions

Engineering Contradiction:
Improvelocking functionVSAvoidpanic direction
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The magnet is made dynamically repositionable within the magnetic rocker through a sliding mechanism in a channel, allowing the same lock body to adapt to different panic directions (left or right) by simply moving the magnet to the appropriate position, eliminating the need for separate left-handed and right-handed variants

Inventive Principle:
Principle #15Dynamics

2Ease of manufacture

If the magnet is fixed in the magnetic rocker during manufacturing, then the production process is simple, but subsequent conversion to different panic directions is impossible

Engineering Contradiction:
Improvemagnet mountingVSAvoiddirection conversion
Core Design Contradiction:
Ease of manufactureVSEase of repair

Solution Approach 1:

The magnetic rocker is segmented into a channel structure that allows the magnet to be independently positioned and secured at different locations, enabling both simple initial assembly and later reconfiguration by moving the magnet along the channel to a new position and securing it with a stop

Inventive Principle:
Principle #1Segmentation

3Reliability

If multiple variants of magnetic rockers are produced for different panic directions, then each variant is optimized for its specific direction, but the device complexity and inventory requirements increase

Engineering Contradiction:
Improvepanic functionVSAvoidnumber of variants
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A single universal magnetic rocker design with a channel and adjustable magnet position can perform both left-handed and right-handed panic functions, replacing the need for multiple specialized variants and reducing inventory complexity while maintaining full functional capability for different installation scenarios

Inventive Principle:
Principle #6Universality (Multi-functionality)
