Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric vehicle wheel mounted generators do not efficiently generate electricity using magnetic coils around the perimeter of the wheel and a stator attached to the vehicle brakes to store it in a supplemental battery for extended vehicle range.
Innovation Solution
The integration of magnetic coils around the perimeter of the vehicle wheel and a stator mounted to the vehicle brakes generates electricity during rotation, which is stored in a supplemental battery system, accompanied by a cleaning mechanism to maintain magnet cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If magnetic coils are placed at the perimeter of the inside of the vehicle wheel and a stator is attached to the vehicle brakes, then electricity generation efficiency is improved, but device complexity increases
Solution Approach 1:
The generator system is divided into separate components: magnetic coils are integrated into the wheel structure while the stator is mounted on the brake assembly. This segmentation allows each component to be optimized independently and simplifies installation and maintenance while maintaining high electricity generation efficiency.
Solution Approach 2:
The wheel assembly serves multiple functions: it provides the structural wheel function, houses the magnetic coils for electricity generation, and integrates with the brake system that contains the stator. This multi-functionality reduces the need for separate dedicated generator components, thereby reducing overall device complexity.
2Duration of action of moving object
If a supplemental battery system is added to store generated electricity, then vehicle range between charges is extended, but device complexity increases
Solution Approach 1:
The supplemental battery system is integrated with the existing vehicle electrical system. The battery pack is positioned to work in conjunction with the main battery and charging system, allowing the generated electricity to be stored and utilized without requiring a completely separate power management infrastructure.
Solution Approach 2:
The system automatically manages the supplemental battery through integrated control circuitry that monitors charge levels, manages power flow between the generator, supplemental battery, and main battery system. This self-managing approach reduces the need for complex manual intervention systems while extending vehicle range.
3Reliability
If a cleaning mechanism with bristles is added to clean magnets, then generator reliability is improved, but device complexity increases
Solution Approach 1:
The cleaning mechanism is designed to automatically clean the magnetic coils during wheel rotation. Bristles are positioned to contact and remove debris from the magnets as the wheel turns, providing continuous self-cleaning without requiring external intervention or complex manual cleaning systems, thereby maintaining generator reliability.
Solution Approach 2:
The cleaning action occurs continuously during wheel rotation rather than requiring periodic stops or separate cleaning operations. The bristles maintain constant contact with the magnets during normal wheel operation, ensuring debris is removed in real-time to maintain optimal generator performance and reliability.
