Conventional generators require rotational driving of armatures or field magnets, leading to increased manufacturing costs, mechanical complexity, and limited power generation efficiency due to mechanical friction, making it difficult to achieve high power generation and conversion efficiency.

Innovation Solution

A non-rotating alternating current (AC) generating device comprising multiple generator units with a round bar-shaped core member, wound field magnet, armature, and insulating plates, where the units are connected in series or parallel, and field magnet currents with phase differences are supplied to generate R-phase, S-phase, and T-phase AC currents.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If rotational driving of armature or field magnet is used, then electrical energy can be generated through electromagnetic induction, but mechanical friction increases and power generation efficiency is limited

Engineering Contradiction:
Improvemechanical friction lossVSAvoidpower generation efficiency
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent replaces the conventional mechanical rotational system with a static electromagnetic system. Instead of rotating the armature or field magnet mechanically, the invention uses a static core member with wound field magnets and armatures that remain stationary. The electromagnetic induction is achieved through alternating current excitation of the field magnets rather than mechanical rotation, thereby eliminating mechanical friction losses entirely while maintaining power generation capability.

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

2Ease of manufacture

If rotational structure is adopted, then electromagnetic induction can occur, but structural complexity and manufacturing cost increase

Engineering Contradiction:
Improvemanufacturing costVSAvoidstructural complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent extracts and removes the rotational mechanical components from the generator system. By eliminating the rotating armature or field magnet structure, the design simplifies the overall device architecture. The remaining static components (core member, wound field magnets, armatures, and insulating plates) form a simpler structure that is easier to manufacture and maintain, while still achieving the essential function of electrical energy generation through static electromagnetic induction.

Inventive Principle:
Principle #2Taking out (Extraction)

3Productivity

If multiple generating units are used, then power generation efficiency increases through synergistic operation, but device complexity increases

Engineering Contradiction:
Improvepower generation efficiencyVSAvoidnumber of generating units
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines multiple generating units into a single integrated device where several sets of wound field magnets and armatures are arranged around a common core member. These units operate synergistically with phase-differentiated alternating current excitation, allowing them to function as a unified power generation system. This merging approach achieves high power generation efficiency while managing complexity through integrated design rather than separate independent units.

Inventive Principle:
Principle #5Merging (Combining)

4Loss of energy

If conventional rotational generator is used, then electrical energy can be generated, but power conversion efficiency is limited

Engineering Contradiction:
Improvepower conversion efficiencyVSAvoidpower conversion rate
Core Design Contradiction:
Loss of energyVSProductivity

Solution Approach 1:

The patent replaces the mechanical rotation-based power conversion with a static electromagnetic field-based conversion system. By using alternating current excitation of stationary field magnets to induce current in stationary armatures, the system achieves more efficient power conversion without the energy losses associated with mechanical friction and rotational inertia. This direct electromagnetic conversion improves the overall power conversion efficiency and rate.
