Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If charging stations are displayed without providing feedback on charging time and operating strategy changes, then the system complexity is reduced, but the user cannot optimize charging planning for fuel efficiency and electrical potential utilization
Solution Approach 1:
The system displays feedback information showing how selected charging times affect the operating strategy and fuel efficiency. This allows users to optimize their charging planning by seeing the direct impact of their choices on vehicle operation modes and energy consumption patterns.
Solution Approach 2:
The system calculates and displays multiple future operating strategies in advance based on different charging time selections. Users can review these pre-calculated strategies before making their final charging decision, enabling informed optimization without real-time computation delays.
2Loss of information
If multiple future operating strategies are displayed based on selected charging times, then user feedback and optimization capability are improved, but the information processing and display complexity increases
Solution Approach 1:
The information is segmented into distinct components: charging time selection, multiple future operating strategies, and their interrelationships. Each element is displayed separately and systematically, making complex information more manageable and comprehensible for users.
Solution Approach 2:
The system adds a temporal dimension by displaying multiple future operating strategies corresponding to different charging time selections. This transforms a single-point decision into a multi-temporal view, allowing users to understand the evolution of operating strategies over time based on their charging choices.
3Adaptability or versatility
If the system allows user selection of charging times with immediate feedback on operating strategy changes, then charging planning flexibility is improved, but the computational requirements and processing time increase
Solution Approach 1:
The system pre-calculates multiple future operating strategies in advance and stores them for quick retrieval. When users select different charging times, the system immediately displays the corresponding pre-computed strategies without requiring real-time calculation, thus maintaining flexibility while minimizing processing time.
4Ease of operation
If charging stations are determined and displayed without providing options for charging time selection, then the device operation is simplified, but users cannot control or optimize their operating strategy
Solution Approach 1:
The system transitions from a static display of charging stations to a dynamic interface where users can select different charging times and immediately see how this affects future operating strategies. This dynamic interaction maintains operational simplicity while enabling comprehensive control and optimization capabilities.
