Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users analyze their own traveling patterns and calculate power consumption to estimate charge requirements, then measurement precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent introduces a simulation device as an intermediary between the user and the complex calculation process. This device automatically acquires traveling pattern data, performs power consumption calculations, and generates charge information estimates, eliminating the need for users to manually analyze their traveling patterns while maintaining high measurement precision
Solution Approach 2:
The simulation device performs self-service by automatically acquiring necessary data (traveling patterns, vehicle specifications) and executing the entire calculation process without user intervention. The system retrieves traveling history data, calculates power consumption based on vehicle characteristics, and outputs charge requirements autonomously
2Loss of information
If users manually calculate charge requirements, then loss of information is reduced, but loss of time increases
Solution Approach 1:
The system performs preliminary actions by pre-acquiring and storing traveling pattern data and vehicle specification data. When a user requests charge information, the simulation device quickly retrieves this pre-prepared data and executes the calculation, significantly reducing the time required while ensuring all necessary information is considered
Solution Approach 2:
The simulation device implements feedback by automatically retrieving actual traveling history data, comparing it with calculated power consumption, and refining charge information estimates. This closed-loop approach ensures information completeness while minimizing manual user input time
