Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two-dimensional schematic images are used for navigation, then the navigation device can be simpler and cheaper to operate, but the navigation becomes confusing and less intuitive when approaching reference targets
Solution Approach 1:
The patent uses a camera to capture real-time images of the actual environment and overlays navigation information (marks, arrows, text) onto these images. This copying approach replaces abstract 2D schematics with real visual copies, making navigation intuitive while keeping the underlying system relatively simple
Solution Approach 2:
The patent introduces an intermediary layer by superimposing graphical navigation elements (marks, arrows, text labels) onto real-time camera images. This intermediary layer bridges the gap between the user's visual perception and navigation instructions, making the interface more intuitive without requiring complete system redesign
2Measurement precision
If three-dimensional schematic images are created for every reference target, then navigation becomes more intuitive and accurate, but the cost and time required for creation and updating increases significantly
Solution Approach 1:
The system uses the camera to automatically capture current environmental images and overlays navigation information in real-time. This self-service approach eliminates the need for manual creation and updating of 3D schematic images, allowing the system to adapt automatically to changing environments without time-consuming updates
Solution Approach 2:
The patent transitions from static pre-created 3D schematic images to dynamic real-time images captured by the camera. The navigation information is overlaid on current images, allowing the system to automatically adapt to changing geographic conditions without requiring manual updates or re-creation of navigation visuals
3Reliability
If three-dimensional schematic images are updated in response to geographic object changes, then navigation accuracy is maintained, but the cost and time required for updating increases
Solution Approach 1:
The camera-based system automatically captures current environmental conditions and overlays navigation information in real-time. This eliminates the need for manual updating of navigation images when geographic objects change, maintaining navigation reliability without incurring additional update costs or time requirements
Solution Approach 2:
The system continuously captures real-time images and overlays navigation information based on current geographic conditions. This feedback mechanism ensures navigation reliability by automatically adapting to changes in the environment without requiring manual intervention or additional updates

AI summary
A navigation apparatus is capable of image-capturing and is used to implement a navigation method including the steps of: a) obtaining current location information associated with the navigation apparatus, and location information of a reference target along a planned route that is being traversed; b) capturing real-time navigation images of the planned route according to an image-capture configuration parameter; c) obtaining a display screen position associated with the reference target with reference to the current location information, the target location information, and the image-capture configuration parameter; and d) showing on the display device the navigation images together with a mark corresponding in position to the display screen position.
