Solution Overview

Problem

Current electric current generators have relatively low overall efficiency due to the need for relative movement between the armature and inductor, which requires significant energy to maintain and results in low energy yield.

Innovation Solution

The proposed apparatus eliminates the need for relative movement between the armature and inductor by using a magnetic shielding structure to generate a variable magnetic field, allowing the armature and inductor to remain static while still inducing electric current.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If relative movement between armature and inductor is used to generate electric current, then electromagnetic induction occurs and current is produced, but significant energy is required to maintain movement and resistance forces reduce overall efficiency

Engineering Contradiction:

Improveenergy loss due to movement maintenanceVSAvoidelectric current generation efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The patent replaces the traditional mechanical relative movement system with a magnetic field modulation system. Instead of mechanically moving the armature relative to the inductor, the invention uses a magnetic shielding structure that can be selectively positioned to modulate the magnetic field, thereby inducing current without the energy-intensive mechanical movement of heavy components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a magnetic shielding structure as an intermediary element between the armature and inductor. This shielding structure, when positioned strategically, modulates the magnetic field flux to induce current in the armature windings, serving as a mediator that eliminates the need for direct mechanical movement between the main magnetic components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Power

If heavy armature and inductor components are set in relative motion, then current generation is achieved, but the considerable mass requires significant energy input

Engineering Contradiction:

Improvepower output of generatorVSAvoidenergy required to set components in motion

Core Design Contradiction:

PowerVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical movement of heavy armature and inductor components with a lighter magnetic shielding structure that can be positioned to modulate the magnetic field. This substitution dramatically reduces the mass that needs to be moved while maintaining the electromagnetic induction process, thereby improving the power-to-energy-input ratio.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the operational parameter from moving heavy magnetic components to positioning a lighter magnetic shielding structure. This parameter change in the system's operation mode reduces the inertial mass involved in the movement, thereby reducing the energy input required to achieve the same current generation output.

Inventive Principle:

Principle #35Parameter changes

3Duration of action of moving object

If continuous relative rotation between armature and inductor is maintained, then current flows through armature coils throughout rotation, but eddy currents generate resistance forces opposing movement

Engineering Contradiction:

Improveduration of current flow through coilsVSAvoidresistance force from eddy currents

Core Design Contradiction:

Duration of action of moving objectVSForce

Solution Approach 1:

The patent uses the magnetic shielding structure as an intermediary to control magnetic field flux modulation. By strategically positioning this shield, the system induces current in the armature windings without requiring continuous rotation, thereby eliminating the eddy current resistance forces that oppose rotational movement while maintaining current flow duration.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent employs periodic positioning of the magnetic shielding structure to modulate the magnetic field flux, creating periodic induction of current in the armature windings. This periodic action replaces continuous rotation, eliminating the continuous eddy current resistance forces while maintaining the essential current generation function throughout the operational cycle.

Inventive Principle:

Principle #19Periodic action
