Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Power

If a battery is mounted to an electric vehicle to provide high energy capacity and high output, then the power and energy of the vehicle are improved, but the battery degradation accelerates under severe driving conditions

Engineering Contradiction:
Improvebattery outputVSAvoidbattery degradation
Core Design Contradiction:
PowerVSReliability

Solution Approach 1:

The system continuously monitors battery operation information including temperature, voltage, and current through sensors, and uses this feedback to dynamically adjust charging/discharging control logic. The remote server collects real-time data and updates control parameters to prevent severe operating conditions that accelerate degradation, thus maintaining reliability while preserving power output capability.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The charging/discharging control logic is made dynamic rather than static. The system adapts control parameters based on real-time battery state and driving conditions, adjusting charging rates, temperature thresholds, and voltage limits dynamically to optimize both power delivery and degradation prevention under varying operational demands.

Inventive Principle:
Principle #15Dynamics

2Reliability

If centralized monitoring and management of battery performance is implemented, then battery life and reliability are improved, but system complexity increases

Engineering Contradiction:
Improvebattery performance managementVSAvoidmonitoring system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A remote server acts as an intermediary between the vehicle's battery management system and external services. The server collects battery operation information, performs centralized analysis, and returns updated control logic, thereby enabling sophisticated monitoring and management without adding complex hardware or processing requirements to the vehicle itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables automated self-service through remote updates of charging/discharging control logic. The battery management system automatically receives and implements updated parameters from the remote server based on collected operation data, eliminating the need for manual intervention or complex user-side analysis tools.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If battery operation information is collected and analyzed to determine residual value and usage fees, then service accuracy and fairness are improved, but data processing complexity increases

Engineering Contradiction:
Improveresidual value determination accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The remote server serves as an intermediary that handles complex data processing for residual value and usage fee determination. It collects battery operation information, applies analysis algorithms, and generates accurate assessments without requiring complex processing capabilities in the vehicle or at the user interface level.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system creates digital copies of battery operation data and processes these copies remotely to determine residual value and usage fees. This allows accurate analysis without duplicating complex processing logic across multiple systems, centralizing the computational burden in the remote server.

Inventive Principle:
Principle #26Copying
