Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited storage capacity of energy storage devices in electric motor vehicles restricts their range, and the time-consuming charging process, especially in areas with insufficient charging infrastructure, deters potential buyers.
Innovation Solution
A vehicle equipped with a permanent energy storage device and an interface for additional replaceable energy storage devices, controlled by an actuating unit to manage energy flow, allowing for increased range and adaptable energy supply during trips or in regions with sparse charging stations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the storage capacity of the permanently installed energy storage device is increased, then the range of the vehicle is extended, but the vehicle becomes less adaptable to varying energy demands and the vehicle is more complex
Solution Approach 1:
The energy storage system is segmented into a permanently installed energy storage device and replaceable energy storage devices. The permanent device provides baseline range, while replaceable devices can be added or removed based on specific travel needs, enabling both extended range and adaptability to varying energy demands.
2Quantity of substance
If multiple replaceable energy storage devices are added to the vehicle, then the storage capacity and range are increased, but the device complexity and difficulty of managing energy flow increase
Solution Approach 1:
Multiple replaceable energy storage devices are electrically merged into a single functional unit through the interface and actuating unit. The system manages multiple devices as if they were one unified energy source, simplifying control while maintaining the ability to scale storage capacity by adding or removing devices.
3Adaptability or versatility
If an interface for replaceable energy storage devices is added, then the adaptability and flexibility of the vehicle are improved, but the device complexity increases
Solution Approach 1:
The interface and actuating unit serve multiple functions: they provide electrical connections for replaceable devices, manage energy flow between devices, monitor system state, and enable user-friendly device replacement. This multi-functionality reduces the need for separate specialized components, balancing adaptability with manageable complexity.
