Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a navigation device displays traveling directions on a photographed picture in real-time, then the navigation functionality is improved, but the device complexity increases
Solution Approach 1:
The patent merges the navigation function with the mobile terminal by integrating the camera, GPS receiver, and navigation display into a single device. The photographed picture serves as both the visual reference and the navigation display background, eliminating the need for separate digital map displays and reducing overall system complexity while enhancing navigation adaptability.
Solution Approach 2:
The mobile terminal achieves multi-functionality by using its camera to capture images that serve dual purposes: as visual records and as navigation display backgrounds. The same photographed picture is utilized for both aesthetic purposes and navigation guidance, allowing one device to perform multiple functions without requiring additional specialized hardware.
2Ease of operation
If real-time navigation is displayed on photographed pictures, then the user experience is improved, but the measurement precision requirements increase
Solution Approach 1:
The system continuously updates the photographed picture with navigation information based on real-time GPS position and camera orientation data. This feedback mechanism ensures that the traveling direction indicator remains accurately aligned with the actual movement direction, maintaining measurement precision while providing an intuitive user experience through real-time updates.
Solution Approach 2:
The patent replaces traditional mechanical map-based navigation systems with a digital image processing approach. By superimposing navigation indicators on photographed pictures using computational methods, the system achieves precise direction indication without requiring physical map references or complex mechanical alignment mechanisms.
3Measurement precision
If traveling directions are indicated on photographed pictures, then the navigation accuracy is improved, but the processing time increases
Solution Approach 1:
The system pre-calculates and stores navigation route information and direction vectors before displaying them on the photographed picture. By preparing the navigation data in advance and using efficient image processing algorithms, the system minimizes real-time processing requirements while maintaining high navigation accuracy through pre-computed directional indicators.
