Problem

Electric vehicles face frequent battery recharging needs, reducing their travel range due to inefficient energy utilization during motion.

Innovation Solution

A suspension power electric generator mounted on electric vehicles converts wasted mechanical energy into electricity using a screw, gears, rotor with magnets, and a stator coil system, capable of recharging batteries while in use, potentially replacing shock absorbers when integrated with a spring system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of moving object

If the electric vehicle uses conventional battery power only, then the vehicle structure is simple, but the travel range is limited due to frequent recharging needs

Engineering Contradiction:
Improvetravel rangeVSAvoidrecharging time
Core Design Contradiction:
Duration of action of moving objectVSLoss of time

Solution Approach 1:

The patent combines the suspension system with an electric generator system, merging two previously separate functions (suspension and power generation) into a single integrated assembly. The generator is mounted within the suspension structure, allowing simultaneous achievement of vehicle suspension and electrical energy generation during motion.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system enables the electric vehicle to recharge its own batteries while in motion through the generator that converts mechanical energy from suspension movement into electrical energy. This self-charging capability eliminates the need for external recharging infrastructure and reduces downtime.

Inventive Principle:
Principle #25Self-service

2Loss of energy

If the electric vehicle captures mechanical energy during motion, then the energy utilization efficiency improves, but the device complexity increases

Engineering Contradiction:
Improvewasted mechanical energyVSAvoidgenerator system complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The generator system is integrated within the existing suspension structure, combining power generation components with suspension elements. This merging approach allows energy capture functionality to be added without proportionally increasing overall system complexity, as the generator shares space and structural support with the suspension system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The suspension system serves dual functions: maintaining vehicle stability and generating electrical energy. The same mechanical movements that perform suspension also drive the generator, making the system multi-functional and reducing the need for separate dedicated components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If the suspension system is replaced with a spring system integrated with the generator, then the energy conversion efficiency increases, but the manufacturing complexity increases

Engineering Contradiction:
Improveenergy conversion efficiencyVSAvoidmanufacturing complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The generator system is divided into modular components including the screw mechanism, planetary gears, rotor with magnets, and stator with coils. Each module can be manufactured and tested independently before assembly, simplifying the manufacturing process despite the complex overall functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The planetary gear system acts as an intermediary mechanism that amplifies the rotational motion from the screw before transmitting it to the rotor. This gear amplification stage enables efficient energy conversion while allowing the screw and rotor to be designed and manufactured as separate, optimized components.

Inventive Principle:
Principle #24Intermediary (Mediator)
