Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users manually plan charging strategies to optimize battery charge, then battery charge management can be optimized, but user burden and complexity increase

Engineering Contradiction:
Improvebattery charge managementVSAvoiduser burden
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system automatically determines charging strategies and displays charging plans without requiring manual user planning. The determination unit autonomously analyzes driving preferences, battery status, and charging conditions to generate optimized charging schedules, allowing the system to serve itself rather than requiring continuous user intervention for battery charge management

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously monitors battery charge levels, driving patterns, and charging conditions, then uses this feedback to dynamically adjust and optimize charging strategies. The display control unit presents charging plans based on real-time data, creating a closed-loop system that automatically adapts to changing conditions without user burden

Inventive Principle:
Principle #23Feedback

2Productivity

If multiple factors affecting battery charge are automatically adjusted, then charging optimization is improved, but system complexity increases

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

Solution Approach 1:

The system segments the complex charging optimization problem into distinct functional units: an acquisition unit that gathers driving preference data, a determination unit that processes this data and determines charging strategies, and a display control unit that presents the charging plan. This modular segmentation allows each unit to handle specific tasks independently, reducing overall system complexity while maintaining comprehensive charging optimization

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary determination of charging strategies by analyzing driving preferences and battery conditions before actual charging occurs. The determination unit pre-calculates optimal charging plans based on anticipated driving patterns and battery state, allowing the system to prepare optimized charging schedules in advance rather than reacting to complex real-time conditions

Inventive Principle:
Principle #10Preliminary action
