Solution Overview

Problem

Conventional electricity generation devices face issues such as pollution, waste disposal concerns, and instability due to weather dependence, while electric vehicle batteries require long charging times and lack widespread charging infrastructure, necessitating a solution for efficient and low-power electricity generation.

Innovation Solution

An electricity generation device with a first motor and second motor setup, where the first motor rapidly rotates a transmission assembly and flywheel, allowing the second motor to operate at low current once a certain speed is reached, achieving low-power consumption through the flywheel's rotor power generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If a single motor is used for continuous electricity generation, then the motor can operate continuously, but the power consumption is high due to continuous startup energy requirements

Engineering Contradiction:
Improvecontinuous operation capabilityVSAvoidpower consumption
Core Design Contradiction:
Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The patent divides the electricity generation system into two separate motors: a first motor that provides initial rotational force to accelerate the flywheel, and a second motor that maintains rotation at lower power consumption. This segmentation allows each motor to operate in its optimal efficiency range, with the first motor operating briefly during startup and the second motor operating continuously at lower power.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The first motor performs preliminary action by accelerating the flywheel to a predetermined rotational speed before the second motor takes over. This preliminary acceleration stores kinetic energy in the flywheel, allowing the second motor to maintain rotation with minimal energy input, thereby reducing overall power consumption while enabling continuous operation.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If green power generation methods are used, then environmental protection is improved, but the power generation is unstable due to weather influence

Engineering Contradiction:
Improveenvironmental protectionVSAvoidpower generation stability
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent changes the operating parameters of the electricity generation device by using a flywheel to store and release kinetic energy, allowing the system to maintain stable power generation regardless of external conditions. The flywheel's rotational inertia provides a buffer that smooths out fluctuations, enabling reliable operation independent of weather conditions while maintaining environmental friendliness.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If electric vehicle batteries are used, then fuel combustion emissions are reduced, but the batteries require long charging times and lack widespread charging infrastructure

Engineering Contradiction:
Improveemission reductionVSAvoidcharging time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The patent implements a self-service electricity generation system where the electric vehicle generates its own power through the dual-motor flywheel system. The first motor accelerates the flywheel to store kinetic energy, and the second motor converts this stored energy back to electrical energy to recharge the battery, creating a self-sufficient power system that reduces dependency on external charging infrastructure and minimizes charging time.

Inventive Principle:
Principle #25Self-service

AI summary

An electricity generation device with low power consumption has an operating module (10), a first motor (20), and a second motor (30). The electricity is inputted to the first motor (20) to actuate the first motor (20), the first motor (20) drives a transmission assembly (18) to rotate, and the transmission assembly (18) drives a flywheel (14) to rotate. A generator rotor (15) is mounted around the flywheel (14), and a generator stator (13) is mounted around an inner peripheral surface of the body (11). The second motor (30) is driven by the transmission assembly (18). When the flywheel (14) reaches a certain rotational speed, the second motor (30) only needs a low current input to keep operating. The second motor (30) can be continuously operated, and the flywheel (14) generates rotor power, thereby achieving power generation at low energy consumption.
