Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users register with multiple providers and use multiple payment cards for different charging stations, then charging operations can be performed at various power sources, but the procedure becomes excessively complicated and time-consuming
Solution Approach 1:
The patent introduces a standardized interface layer between the electric vehicle and diverse charging providers. This interface acts as an intermediary that translates between different provider systems and the vehicle's charging system, enabling universal charging without requiring users to register with multiple providers or manage multiple payment methods. The standardized interface handles provider-specific protocols internally while presenting a uniform user experience.
Solution Approach 2:
The patent implements a universal charging card or payment method that can be used across all charging providers. Instead of requiring separate registration and payment systems for each provider, the system enables a single payment method to function universally across the entire charging infrastructure, simplifying the user procedure while maintaining compatibility with multiple providers.
2Reliability
If previous registration with providers is required for charging, then payment and charging parameters can be pre-configured, but spontaneous charging at unknown providers becomes impossible
Solution Approach 1:
The patent implements pre-configured payment methods that are stored and ready for use before charging occurs. The system prepares payment authorization and charging parameters in advance through a standardized interface, so that when a user encounters an unknown provider, the payment is already authorized and can proceed immediately without requiring prior registration with that specific provider.
Solution Approach 2:
The system enables automatic recognition and authorization between the electric vehicle and charging providers through the standardized interface. The vehicle can autonomously identify compatible charging stations, initiate charging, and handle payment without requiring user registration or manual configuration, enabling spontaneous charging at unknown providers while maintaining secure payment processing.
3Adaptability or versatility
If each provider implements separate payment methods, then provider-specific charging parameters can be optimized, but users must carry multiple payment cards and accounts
Solution Approach 1:
The patent merges multiple provider-specific payment methods and accounts into a single universal payment system. The standardized interface consolidates the functionality of multiple payment cards and accounts into one unified method that can access all providers' charging services. This reduces the quantity of payment instruments the user must carry while preserving access to provider-specific charging options through the unified interface.
4Manufacturing precision
If users perform excessive effort before each charging operation, then charging parameters can be precisely configured, but charging speed and efficiency are reduced
Solution Approach 1:
The system implements automatic configuration of charging parameters through the standardized interface. When a charging operation is initiated, the system automatically negotiates and configures the appropriate charging parameters between the vehicle and the charging provider without requiring user intervention. This maintains precise parameter configuration while dramatically reducing the time and effort required before charging begins.
Solution Approach 2:
The system performs automatic parameter negotiation and configuration in advance as part of the standardized interface handshake process. By the time the user initiates charging, all parameters are already optimized and configured, eliminating the need for manual setup and enabling immediate charging operation with precise parameter configuration already in place.

AI summary
A charging system for quickly and securely performing charging operations of electric vehicles includes at least one electric vehicle, at least one power source, and at least one smart contract. The at least one electric vehicle includes at least one electrical energy store. The at least one power source is configured to charge the energy store. The charging parameters for a charging operation of the electrical energy store are negotiable between the electric vehicle and the power source. The negotiation of the charging parameters comprises determining a charging requirement of the electrical energy store by means of the electric vehicle. The charging operation of the electrical energy store is performable with the aid of a smart contract.
