Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicles face limitations due to short battery life, restricting their travel distance between charges.
Innovation Solution
An energy-producing system integrated with the vehicle's wheels, featuring wind-catching cups within an aerodynamic housing that generates energy through air flow, which is then directed into the vehicle's batteries, using a generator/alternator and polarized magnets to maintain axle motion during stops, and a power controller to distribute and enhance power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If electric vehicles use battery power only, then the vehicle can operate quietly and smoothly, but the battery life is short and travel distance is limited
Solution Approach 1:
The patent combines the traditional battery power system with a wind energy generation system. The wind-catching cups mounted on the vehicle convert kinetic energy from moving air into electrical energy through a generator, which then charges the battery. This merging of external wind energy conversion with the existing battery system extends the effective battery life and travel distance without compromising the quiet and smooth operation characteristics of electric vehicles.
2Productivity
If the vehicle moves faster, then more energy can be generated by the wind cups, but the aerodynamic drag increases
Solution Approach 1:
The wind-catching cups are designed to be dynamically adjustable in their orientation and position. As vehicle speed increases, the cups can adjust their angle of attack and rotational position to optimize energy capture while minimizing aerodynamic resistance. This dynamic adjustment allows the system to maximize energy generation at higher speeds without proportionally increasing drag, resolving the contradiction between productivity and harmful aerodynamic factors.
3Power
If wind-catching cups are added to the vehicle, then energy can be generated during motion, but the device complexity increases
Solution Approach 1:
The wind-catching cup system is designed to serve multiple functions: it generates electrical energy through the generator, acts as an aerodynamic device to manage airflow around the vehicle, and can be integrated with the vehicle's existing structural components. The generator is coupled to the vehicle's existing wheel rotation mechanism, and the cups can be mounted on existing aerodynamic surfaces. This multi-functionality reduces the need for entirely separate systems, thereby limiting the increase in device complexity while maintaining energy generation capability.

Function Achieved in This Case
Extends battery life and increases the distance an electric vehicle can travel between charges by generating additional energy during motion and optimizing power distribution.
Implementation Method 1
During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle
Implementation Method 2
the rotation may be transferred into energy via a generator/alternator linked thereto
Implementation Method 3
A series of similarly polarized magnets integrated on said cups and proximate thereto (e.g., on spacers) further maintain the axle in motion during intermittent vehicle stops

AI summary
An energy-producing system comprising an axle configured to be driven by an electric vehicle's wheels when in motion. The axle supports a series of wind-catching cups contained within an aerodynamic housing configured to direct air to the cups while also increasing the air speed. During vehicle motion, the cups are acted upon by rushing air causing the rotation of the axle such that the rotation may be transferred into energy via a generator/alternator linked thereto. A series of similarly polarized magnets integrated on said cups and/or spacers and/or housing proximate thereto further maintain the axle in motion during short vehicle stops. The system extends the life of the batteries between charges as well the distance the vehicle can travel between charges. A power controller is configured to distribute power from said generator to an axle drive motor, vehicle drive motor and/or start-up battery pack.
