Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation application uses pre-stored map data and fixed routing algorithms, then device complexity is reduced, but information accuracy deteriorates due to transient nature of roads and points of interest
Solution Approach 1:
The patent implements a feedback mechanism where users can report incorrect or outdated navigation information through the application interface. This feedback is transmitted to remote servers that update the navigation data, ensuring continuous improvement of information accuracy without requiring complex real-time verification systems in the vehicle.
Solution Approach 2:
The system performs preliminary actions by pre-calculating multiple potential routes and storing them in advance. When navigation is needed, the system can quickly switch between pre-prepared routes based on current conditions, avoiding the need for complex real-time route recalculation while maintaining accuracy.
2Reliability
If navigation application frequently updates route information in real-time, then information accuracy is improved, but energy consumption increases
Solution Approach 1:
The navigation application implements periodic updates rather than continuous real-time updates. The system checks for route changes at predetermined intervals or when specific triggers occur (e.g., completing a road segment), reducing computational frequency while maintaining sufficient information accuracy.
Solution Approach 2:
The system uses passive updates where navigation data is automatically refreshed in the background during low-power states or when the vehicle is stationary, rather than actively polling for updates during high-power consumption driving states. This self-service approach minimizes energy usage while keeping information current.
3Reliability
If navigation application processes and analyzes user feedback in real-time, then information accuracy is improved, but processing time increases
Solution Approach 1:
The patent introduces remote servers as intermediaries that handle the complex processing of user feedback. The vehicle's navigation system collects feedback and transmits it to remote servers for analysis and validation, then receives updated information. This distributes processing time and reduces the time loss in the vehicle's own system.
4Ease of operation
If navigation application provides detailed contextual feedback options, then user control is improved, but device complexity increases
Solution Approach 1:
The feedback interface is segmented into multiple levels: a simple primary feedback option (e.g., thumbs up/down) and expanded secondary options that appear only when needed. This segmentation provides detailed control capabilities while keeping the default interface simple and easy to operate.
Solution Approach 2:
The system implements partial action by providing only the most commonly needed feedback options by default, with additional detailed options available on demand. This approach gives users sufficient control for most situations without presenting the full complexity of all possible feedback types, easing operation while maintaining necessary functionality.
