Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If users constantly monitor battery levels and manually find charging stations, then battery status can be tracked, but user convenience deteriorates and time is wasted

Engineering Contradiction:
Improvebattery level monitoringVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The system enables self-service by automatically monitoring battery levels through wireless communication between the electric vehicle, battery energy station, and server. The vehicle controller and station controller exchange data without user intervention, and the server automatically sends swap reminders when batteries need replacement, eliminating the need for users to manually check battery status.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements continuous feedback loops where the vehicle controller reports battery levels to the server, the server compares current levels with historical data, and automatically sends swap reminders when thresholds are reached. This closed-loop feedback system ensures timely battery monitoring and notification without user effort.

Inventive Principle:
Principle #23Feedback

2Productivity

If battery swap mechanism is implemented, then charging efficiency improves, but system complexity increases due to need for battery management and matching

Engineering Contradiction:
Improvecharging efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system divides battery management into independent modular components: vehicle controllers in each electric vehicle, station controllers at battery energy stations, and a central server for coordination. This segmentation allows each component to perform specific functions independently, simplifying the overall complex system while enabling efficient battery swap operations through coordinated modular units.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The server performs multiple functions including receiving vehicle information, determining swap needs, selecting appropriate candidate batteries based on various criteria, and coordinating the actual swap process. This multi-functional approach consolidates complex battery management tasks into a single universal system that handles all aspects of battery swap operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Ease of operation

If early swap reminders are provided, then user satisfaction increases, but communication infrastructure requirements increase

Engineering Contradiction:
Improveuser satisfactionVSAvoidcommunication infrastructure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The server acts as an intermediary between the battery energy station and the user's mobile device. It receives battery level data from the station controller, processes swap determination logic, and sends swap reminders to the user's terminal through wireless networks. This intermediary approach simplifies direct communication requirements by using the server as a central communication hub that manages all information exchange.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A battery swap management method, for use in a battery energy station for storing and charging a plurality of candidate batteries and an electric vehicle, is provided. Initially, the electric vehicle connects to the energy station through a wireless network. Next, the electric vehicle obtains a specific battery's specific battery level and transmits the specific battery level to the battery energy station through the wireless network. Then, the battery energy station obtains each candidate battery's candidate battery level, and determines whether the candidate battery's candidate battery level is lower than the specific battery's specific battery level. Lastly, when each candidate battery's candidate battery level is lower than the specific battery's specific battery level, the battery energy station sends an unswappable instruction to the electric vehicle through the wireless network.
