Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If EV charging is continuously supplied to meet consumer energy needs, then consumer energy demand is satisfied, but peak load on the electric energy grid increases
Solution Approach 1:
The system dynamically adjusts EV charging power supply based on real-time grid load conditions. The controller monitors grid demand and automatically modulates charging rate or pauses charging when peak load is detected, transforming static charging into a dynamic response system that adapts to changing grid conditions.
Solution Approach 2:
The system implements feedback control by continuously monitoring grid load conditions and using this information to adjust charging operations. The controller receives grid status signals and modifies charging power accordingly, creating a closed-loop system that responds to actual grid conditions rather than operating in isolation.
2Power
If EV charging is reduced or stopped during peak load to alleviate grid strain, then peak demand is reduced, but consumer energy availability is limited
Solution Approach 1:
The system uses periodic monitoring of grid load conditions to determine when to pause or reduce charging. Rather than continuous interruption, the controller implements periodic checks and temporary suspensions of charging during identified peak load periods, allowing charging to resume when conditions improve.
Solution Approach 2:
The system provides advance notification to consumers about upcoming peak load periods and potential charging interruptions. This preliminary information allows users to plan alternative charging strategies or adjust their schedules before grid conditions deteriorate.
3Ease of operation
If remote control capability is added to enable dynamic charging management, then user control over energy consumption is improved, but device complexity increases
Solution Approach 1:
The system uses a communication module as an intermediary between the adapter and the user's mobile device. This intermediary handles the complexity of remote control, authentication, and command transmission, allowing users to control charging from a distance without directly interacting with the adapter's internal systems.
Solution Approach 2:
The adapter incorporates automatic grid load monitoring and autonomous decision-making capabilities that reduce the need for constant user intervention. The system can automatically detect peak load conditions and adjust charging without requiring user action, while still providing remote control options when desired.

AI summary
An electric vehicle charger adapter may be configured to be controlled by a remote device in response to receiving a notification that high-electricity demand on an electricity power grid as measured by an energy provider. The notification may be communicated to a cloud server, mobile app, hub of an alarm system, and/or otherwise, and a notification or command may be communicated to the adapter for altering charging of an electric vehicle (EV). The charging alteration may be performed by reducing or stopping charging of a rechargeable battery of the EV.
