Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional magnetic attachment systems are used, then attachment strength is achieved, but assembly and disassembly processes become complex and require significant force

Engineering Contradiction:

Improveease of assembly and disassemblyVSAvoidcomplexity of attachment mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical locking mechanisms with a magnetic field-based system. Motion magnets in the retaining means interact with contact magnets in the engagement means through magnetic attraction and repulsion forces, eliminating the need for complex mechanical interlocking components while achieving secure attachment and easy release through simple relative movement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent utilizes changes in magnetic field parameters (attraction/repulsion) to control the state of attachment. By positioning magnets with specific polarities (north and south poles), the system transitions between locked and unlocked states based on magnetic force parameters, enabling simple operation without mechanical complexity.

Inventive Principle:

Principle #35Parameter changes

2Strength

If strong magnetic forces are used for secure attachment, then retention strength is improved, but disassembly becomes difficult requiring excessive force

Engineering Contradiction:

Improveattachment retention strengthVSAvoidease of disassembly

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent inverts the traditional approach by using repulsive magnetic forces to facilitate disassembly. The motion magnets are positioned such that when the item is rotated relative to the base, the magnetic interaction switches from attraction (locking) to repulsion (unlocking), allowing easy disassembly without overcoming strong attractive forces.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent creates a dynamic magnetic interaction system where the force character (attractive or repulsive) changes based on the relative position and orientation of the magnets. This dynamic behavior allows the same magnetic system to provide strong retention during normal use while enabling easy release through simple rotational movement.

Inventive Principle:

Principle #15Dynamics
