Solution Overview

Problem

Existing locking systems with cylindrical magnets face issues of permanent locking due to overlapping housings, increased complexity, higher costs, and susceptibility to wear and failure, especially when using multiple components.

Innovation Solution

The system employs spherical and cylindrical magnets in pairs within housings, combined with ferromagnetic and magnetically inert elements to allow relative movement, simplifying assembly and reducing component count, thus avoiding permanent locking and enhancing durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cylindrical magnets are used in overlapping housings, then the locking function is achieved, but the device becomes permanently locked and movement is restricted

Engineering Contradiction:
Improvelocking functionVSAvoidmovement of planes
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces cylindrical magnets with spherical magnets in the overlapping housings. The spherical shape allows the magnets to roll along the sliding plane during movement, preventing them from becoming permanently locked in position. This curvature enables continuous movement while maintaining the locking function when stationary.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The patent introduces a dynamic element by using spherical magnets that can change their position and orientation during operation. The magnets transition from a static locked position to a dynamic rolling motion, allowing the planes to move freely while maintaining locking capability when at rest.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If multiple components are used to prevent permanent locking, then movement is enabled, but the device complexity and cost increase

Engineering Contradiction:
Improvemovement of planesVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into the spherical magnet itself. The spherical magnet simultaneously provides the locking function, enables movement through rolling, and eliminates the need for separate limiting components. This merging reduces the total number of parts while achieving the desired operational freedom.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The spherical magnet serves multiple functions: it provides magnetic attraction for locking, enables rolling motion for movement, and acts as its own positioning mechanism. This multi-functionality eliminates the need for additional specialized components, simplifying the overall device structure.

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

3Ease of operation

If multiple components are used to enable movement, then operational freedom is achieved, but wear and susceptibility to failure increase

Engineering Contradiction:
Improvemovement of planesVSAvoidwear and failure
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The spherical magnet introduces dynamic rolling motion instead of sliding friction between multiple components. This reduces wear by eliminating contact between separate moving parts, as the spherical magnet rolls along the sliding plane with minimal friction and no additional wear surfaces.

Inventive Principle:
Principle #15Dynamics
