Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack flexibility in logistical tasks, particularly in energy supply and operation, especially when moving above a floor surface or performing conveying tasks, as they are limited by the need for continuous energy sources and lack efficient inductive energy transfer capabilities.
Innovation Solution
The vehicle is equipped with underside coil windings for inductive energy transfer, allowing energy sharing between vehicles, and features an electric motor-driven wheel or roller system with a conveyor unit that can operate above the floor, utilizing an energy store and converter for movement and logistical tasks, with synchronized inductive coupling and regenerative feedback for efficient energy management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a vehicle is equipped with an energy store and electric drive, then the vehicle can be moved along a floor surface, but the vehicle lacks flexibility in logistical tasks and requires continuous energy sources
Solution Approach 1:
The patent introduces an intermediary inductive energy transfer system consisting of primary windings in the floor and secondary windings in the vehicle. This mediator enables wireless energy transfer, allowing the vehicle to operate flexibly without continuous physical connection to energy sources, thereby resolving the contradiction between operational flexibility and continuous energy requirement
Solution Approach 2:
The vehicle is designed with multi-functionality, capable of performing both self-propelled movement and conveying tasks for other objects. The same electric drive and energy store serve multiple purposes, enhancing logistical flexibility while managing energy requirements efficiently through inductive charging capabilities
2Adaptability or versatility
If windings are arranged on the side surface of the vehicle, then inductive energy transfer is enabled, but the device complexity increases
Solution Approach 1:
The winding system is segmented into separate primary windings (in the floor) and secondary windings (in the vehicle). This segmentation allows each component to be optimized independently and simplifies the overall system design, reducing complexity while maintaining full inductive energy transfer functionality
Solution Approach 2:
The patent transitions from traditional onboard energy storage to a spatially distributed inductive energy transfer system. By placing primary windings in the floor plane and secondary windings on the vehicle, the system adds a spatial dimension to energy transfer, simplifying vehicle design while enabling flexible energy supply
3Quantity of substance
If multiple vehicles are coupled in a convoy with synchronized movement, then energy can be shared between vehicles, but the control system complexity increases
Solution Approach 1:
The convoy control system implements feedback mechanisms where the master vehicle monitors and coordinates the slave vehicles' positions and energy states. This feedback enables automatic synchronization and facilitates energy sharing through the inductive coupling system, managing complexity through intelligent control rather than mechanical complexity
Solution Approach 2:
Multiple vehicles are merged into a coordinated convoy system where they operate as a unified entity for energy sharing and task execution. The master-slave configuration combines the capabilities of individual vehicles while managing control complexity through a hierarchical structure
