Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large electric vehicles, such as dump trucks, face difficulties in being mechanically towed when their power source is depleted, and existing technologies fail to provide a reliable power supply in the absence of overhead wiring.
Innovation Solution
An electric vehicle system that enables power interchange between two electric vehicles using a connection device, incorporating features like distance measurement, speed control, and a connection line that prevents disconnection, allowing continuous operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the vehicle mass is increased to improve cargo capacity, then the vehicle can carry more material, but it becomes difficult to mechanically tow when power is depleted
Solution Approach 1:
The patent introduces a connection device with connection wires as an intermediary mechanism between the power-depleted vehicle and the assisting vehicle. This allows direct electrical power transfer to enable self-propelled movement, bypassing the need for mechanical towing of heavy vehicles.
2Adaptability or versatility
If a generator is used to provide power when overhead wiring is unavailable, then the vehicle can run without overhead wiring, but it cannot operate when fuel is depleted
Solution Approach 1:
The connection device serves as a mediator that enables direct power transfer from another vehicle's overhead wiring supply to the power-depleted vehicle, providing a more reliable power source than fuel-dependent generators.
Solution Approach 2:
The system enables multiple power supply modes: overhead wiring, storage battery, and inter-vehicle power transfer. This multi-functionality ensures the vehicle can operate under various conditions including when fuel is depleted.
3Speed
If mechanical towing is used to move a power-depleted vehicle, then the vehicle can be moved, but it is not feasible for large mass vehicles
Solution Approach 1:
The patent replaces the mechanical towing system with an electrical power transfer system. Instead of using mechanical force to move the heavy vehicle, electrical power is transferred through connection wires to enable the vehicle's own motor to propel it, effectively substituting mechanical assistance with electrical assistance.
4Ease of operation
If connection wires are made flexible to allow vehicle movement, then the vehicle can move while connected, but the wires may come off or disconnect
Solution Approach 1:
The connection device incorporates dynamic elements including telescopic structures and rotation mechanisms that allow the connection wires to adapt to vehicle movements while maintaining stable electrical connection, preventing disconnection during operation.
