Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles are limited in their ability to provide power to internal or external devices due to outlets with predetermined ratings, which restrict the types and number of devices that can be powered simultaneously.
Innovation Solution
A vehicle is equipped with a socket having an array of power terminals that can accept outlets of different configurations, paired with power converters and a controller that communicates electrical ratings to adjust the power delivery based on load requirements, allowing for flexible interconnection and operation of power converters to meet the demands of connected devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If outlets have predetermined ratings and electrical provisions, then the electrical safety and stability are ensured, but the adaptability to different devices and the number of devices that can be powered are limited
Solution Approach 1:
The outlet system dynamically reconfigures its electrical connections based on the detected device requirements. The controller adjusts the switching scheme in real-time to match the electrical rating and power needs of the connected device, transforming a static outlet into an adaptive interface that maintains safety while providing versatility.
Solution Approach 2:
The system changes electrical parameters (voltage, current, switching configuration) based on the detected device characteristics. By varying these parameters dynamically, the outlet can accommodate different device types and power requirements while maintaining electrical safety through controlled parameter adjustment.
2Power
If outlets have predetermined ratings, then the electrical safety is maintained, but the power flexibility and ability to satisfy different load requirements are reduced
Solution Approach 1:
The controller receives feedback from the detected device electrical rating and uses this information to adjust the power converter operation and switching scheme. This closed-loop feedback mechanism ensures that power delivery is optimized for the connected device while maintaining electrical safety through continuous monitoring and adjustment.
Solution Approach 2:
The system dynamically adjusts power converter operation and switching configurations based on real-time device detection. This dynamic adaptation allows the outlet to provide flexible power delivery for different load requirements while maintaining reliability through controlled, monitored changes in electrical parameters.
3Productivity
If a single power converter is used, then the device complexity is reduced, but the ability to satisfy high power loads and multiple devices simultaneously is limited
Solution Approach 1:
The system merges multiple power converters into a coordinated system that works together to satisfy power demands. By combining the output of multiple converters and using intelligent switching, the system achieves higher power capability while managing complexity through centralized controller coordination.
Solution Approach 2:
The power delivery function is segmented across multiple power converters, each handling specific portions of the total load. This segmentation allows the system to satisfy high power loads and multiple devices simultaneously while maintaining manageable complexity through modular architecture and intelligent load distribution.
