Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a map is simply displayed on the display unit of a mobile electronic device, then the device structure remains simple, but the usefulness and functionality of the map cannot be fully utilized
Solution Approach 1:
The patent combines multiple functions (imaging unit for capturing maps, processing unit for analyzing map data, display unit for showing information, and image projecting unit for projecting onto surfaces) into a single mobile electronic device. This integration allows the device to capture real-world maps, process them to extract location information, and present enhanced map data through multiple output channels, thereby fully utilizing map functionality without requiring separate dedicated devices for each function.
Solution Approach 2:
The mobile electronic device is designed with multi-functionality to handle various map-related tasks: the imaging unit captures physical maps, the processing unit analyzes and interprets map data to identify locations and coordinates, the display unit presents processed information, and the image projecting unit projects map-related images onto physical surfaces. This universal design enables a single device to perform diverse map utilization functions that would otherwise require multiple specialized devices.
2Loss of information
If map information is enhanced with additional data and images, then the information completeness improves, but the processing complexity increases
Solution Approach 1:
The processing unit performs preliminary actions by pre-processing map images to extract location information, coordinates, and relevant data before display or projection. The device captures the map image, automatically identifies geographical features and locations, converts real-world coordinates to display coordinates, and prepares enhanced information in advance. This preliminary processing reduces the complexity of real-time operations and ensures information completeness is achieved through systematic pre-analysis rather than complex runtime processing.
3Illumination intensity
If the device projects images onto external surfaces, then the visualization capability improves, but the requirement for additional hardware components increases
Solution Approach 1:
The patent merges the image projecting unit with other device components (imaging unit, processing unit, display unit) into a single integrated mobile electronic device. The projecting unit shares the device's power supply, processing capabilities, and control systems with other components, thereby enhancing visualization capability through external projection without requiring a completely separate projection device. This integration reduces overall system complexity compared to using independent dedicated devices for each function.
