Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If geographic element data is displayed on a mobile computing device, then information about nearby points of interest is provided to users, but the display system becomes complex requiring integration of camera, position determination, and image processing components
Solution Approach 1:
The patent combines multiple functions (camera imaging, position determination, image processing, and geographic data display) into a single integrated mobile computing device system. The processing circuit concurrently handles image data from the camera and geographic element data, merging these separate functions into one cohesive system that reduces overall system complexity despite the multiple capabilities involved.
Solution Approach 2:
The mobile computing device is designed with multi-functionality, serving as both a camera device and a navigation/information device. The same display system presents both image data and geographic element data, making the device universal in its capabilities rather than requiring separate dedicated devices for each function.
2Productivity
If the display system concurrently shows image data and geographic element data, then real-time information about geographic elements is provided, but the processing requirements and computational load increase
Solution Approach 1:
The system determines camera orientation and processes image data in real-time as preliminary actions before displaying geographic element data. By continuously monitoring camera orientation and pre-processing image data, the system prepares information ahead of time, enabling fast concurrent display without excessive computational delay.
Solution Approach 2:
The display system dynamically adjusts by concurrently processing and displaying both image data and geographic element data based on real-time camera orientation. The processing circuit adapts to changing orientation data, dynamically updating the display to maintain accurate geographic information alignment with the captured images.
3Measurement precision
If the system determines camera orientation using image processing algorithms, then accurate alignment of geographic data with images is achieved, but the processing time and computational resources increase
Solution Approach 1:
The system continuously determines camera orientation using image processing algorithms rather than performing discrete, periodic measurements. This continuous action maintains accurate alignment between geographic data and images in real-time, ensuring measurement precision is sustained without requiring repeated processing cycles that would increase total processing time.
Solution Approach 2:
The patent replaces traditional mechanical orientation sensors with image processing algorithms that analyze camera images to determine orientation. This substitution uses computational methods instead of mechanical measurement systems, achieving accurate camera orientation determination while reducing mechanical complexity and potentially processing time through software-based solutions.
