Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If screws and connectors are used to fix the shell and frame, then the connection is strong and stable, but the maintenance and installation become inconvenient due to inability to completely separate components

Engineering Contradiction:

Improveconnection strengthVSAvoidease of maintenance and installation

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent replaces the traditional mechanical screw connection system with a magnetic field-based connection system. Magnetic members are embedded in both the shell and frame, creating a magnetic attraction force that provides strong connection strength while allowing complete separation without wires, thus resolving the contradiction between connection strength and ease of maintenance.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the wires from the connection system between the shell and frame. By using magnetic attraction alone to hold the components together, the wires are completely removed, enabling complete separation during maintenance while maintaining strong connection during use.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If numerous wires are connected between the shell and frame for circuit connections, then the electrical connections are established, but the maintenance and installation become inconvenient due to wire interference

Engineering Contradiction:

Improveelectrical connection reliabilityVSAvoidease of maintenance and installation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the wire-based electrical connection system with a magnetic field-based system. Magnetic members serve dual functions: providing mechanical attraction and establishing electrical connections through the magnetic field, eliminating wire interference while maintaining reliable electrical connectivity between power supply and power consumption components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The magnetic members perform multiple functions simultaneously: they provide mechanical attraction to hold the shell and frame together, and they establish electrical connections between components. This multi-functionality eliminates the need for separate wires, resolving the contradiction between electrical connection reliability and ease of maintenance.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Stability of the object's composition

If the shell and frame are fixedly connected, then the structural stability is maintained, but the separation and assembly time increases during maintenance

Engineering Contradiction:

Improvestructural stabilityVSAvoidseparation and assembly time

Core Design Contradiction:

Stability of the object's compositionVSLoss of time

Solution Approach 1:

The patent replaces the time-consuming mechanical screw tightening process with a rapid magnetic attraction process. The magnetic members automatically attract and connect the shell and frame when brought close, providing structural stability without requiring time-consuming assembly operations, thus resolving the contradiction between structural stability and assembly time.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
