Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional rolling vehicles are used on rail structures, then the system is simple and compatible with existing infrastructure, but frictional resistance increases and energy consumption rises

Engineering Contradiction:
Improvecompatibility with existing infrastructureVSAvoidenergy consumption
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent replaces the conventional mechanical rolling contact system with a magnetic field-based levitation system. Magnetic flux paths are established through the rail structure using magnetizable materials, creating magnetic forces that levitate and propel the vehicle without physical contact, thereby eliminating friction and reducing energy consumption while maintaining infrastructure compatibility.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of energy

If magnetic levitation technology is implemented, then frictional resistance is reduced and energy consumption decreases, but the complexity of magnetic flux path design increases

Engineering Contradiction:
Improveenergy consumptionVSAvoidmagnetic flux path design
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The patent applies local quality by incorporating magnetizable materials specifically in strategic locations within the rail structure where magnetic flux paths are needed. Rather than making the entire rail structure complex, only specific regions are enhanced with magnetic properties to guide flux paths and generate levitation forces, simplifying the overall design while achieving the desired magnetic effects.

Inventive Principle:
Principle #3Local quality

3Ease of manufacture

If the connection portion lateral dimension is reduced, then material usage and manufacturing cost decrease, but magnetic flux path efficiency may be compromised

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent optimizes the lateral dimension of the connection portion by carefully selecting and adjusting geometric parameters. The connection portion's lateral dimension is reduced to minimize material usage and cost, while the vertical dimension and magnetic material properties are simultaneously optimized to maintain adequate magnetic flux path efficiency, achieving a balanced design that satisfies both economic and performance requirements.

Inventive Principle:
Principle #35Parameter changes
