Solution Overview
Problem
Existing vehicle trailer electrical systems are unreliable due to susceptibility to contamination and faults, often failing to ensure a consistent supply of electrical energy, as they rely on complex and prone-to-failure mechanisms for energy generation.
Innovation Solution
A vehicle trailer equipped with a drivable electrical generator using a ring of permanent magnets on the brake hub or a separate magnet carrier interacting with a stationary coil, inducing voltage through movement, which is connected to a charger and storage system, ensuring reliable energy supply and reduced maintenance needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional transmission means (friction rollers, toothed belts) are used to connect the generator to the wheel, then the generator can be driven by wheel rotation, but the system becomes susceptible to contamination and faults
Solution Approach 1:
The patent replaces the conventional mechanical transmission system (friction rollers, toothed belts) with a direct magnetic coupling system. The generator is mounted directly on the wheel hub, and magnetic fields are used to transfer rotational motion without physical contact between moving parts. This eliminates contamination risks from mechanical components while maintaining reliable energy generation.
Solution Approach 2:
The generator is integrated directly into the wheel hub structure, merging the drive source and the energy generation system into a single unified component. This eliminates the need for separate transmission mechanisms and reduces the number of moving parts that could fail or become contaminated.
2Reliability
If a magnetic coil arrangement with magnets on the wheel and stationary coil on the fork is used, then electrical energy can be generated from wheel rotation, but the system is susceptible to contamination from contact between moving and stationary parts
Solution Approach 1:
The patent replaces contact-based magnetic coupling with a contactless magnetic field interaction system. The generator uses magnetic fields to transfer rotational energy from the wheel to the stationary coil assembly without any physical contact between moving and stationary components, eliminating contamination pathways.
Solution Approach 2:
The magnetic field acts as an intermediary between the rotating wheel and the stationary generator components. This field-based mediation allows energy transfer without direct contact, preventing contamination from being transmitted between moving and stationary parts.
3Adaptability or versatility
If complex electrical systems and control systems are installed in the trailer, then the trailer has advanced functionality, but sufficient electrical energy cannot always be guaranteed to reach the trailer
Solution Approach 1:
The trailer generates its own electrical energy through the wheel-driven generator system, making it self-sufficient. The generator converts the kinetic energy from wheel rotation into electrical energy, allowing the trailer to power its own electrical systems without relying entirely on external power sources from the towing vehicle.
Solution Approach 2:
The generator operates periodically during trailer movement, converting kinetic energy to electrical energy during motion. This periodic energy generation ensures that electrical systems remain powered during transit, complementing the trailer's electrical infrastructure.
