Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard household electrical outlets are not adequately equipped to handle the high current demands of charging electric vehicle batteries, leading to uncertainty about the outlet's capacity and potential safety risks due to the inability to communicate the maximum intensity of the electrical signal they can deliver without being damaged.
Innovation Solution
An electrical socket with identification means that communicates with an electrical plug to generate a control signal representing the maximum intensity of the electrical signal it can deliver without being damaged, allowing the plug and connected device to adjust its operation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a standard household electrical outlet is used to charge electric vehicle batteries, then the outlet can deliver high current (14-16 Amps), but the outlet may be damaged due to uncertainty about its intrinsic characteristics and maximum delivery capacity
Solution Approach 1:
The electrical outlet includes identification means that generate a control signal indicating the maximum intensity of electrical signal the outlet can permanently deliver without being damaged. This feedback mechanism allows the charging device to adapt its current draw to the outlet's actual capacity, preventing outlet damage while enabling safe high-power charging when appropriate.
Solution Approach 2:
The outlet's identification means proactively provide information about its current delivery capacity before charging begins. This preliminary action allows the charging device to configure appropriate charging parameters in advance, avoiding situations where the outlet is overloaded beyond its safe operating limits.
2Reliability
If the electrical outlet provides identification means to communicate maximum intensity, then the device can adapt its operation safely, but the device complexity of the outlet increases
Solution Approach 1:
The identification means in the outlet generate a control signal that serves as an intermediary communication channel between the outlet and the charging device. This control signal conveys the outlet's maximum current capacity without requiring complex real-time monitoring or control systems, simplifying the overall design while maintaining safety and adaptability.
3Productivity
If the outlet delivers maximum current (16 Amps) for extended periods, then charging efficiency is improved, but the outlet may overheat or be damaged
Solution Approach 1:
The identification means provide real-time feedback about the outlet's maximum safe current delivery capacity. This allows the charging device to draw current at the optimal rate that maximizes charging speed while staying within the outlet's thermal and electrical limits, preventing overheating and damage during extended charging periods.
