Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional surveying instruments and systems are used to acquire geographic data, then measurement precision is improved, but device complexity and operation time increase significantly
Solution Approach 1:
The patent combines multiple functions (image pickup, distance measurement, coordinate measurement, and image processing) into a single integrated portable device. The image pickup unit captures images of objects, the distance measuring unit measures distances to specified points, the coordinate measuring unit acquires coordinate data, and the image processing unit matches images with measurement data to display measuring points on the image. This integration eliminates the need for separate surveying instruments and simplifies the measurement procedure while maintaining precision.
Solution Approach 2:
The patent uses image copying and matching techniques to transfer measurement data to visual representations. The image processing unit matches the captured image with the result of surveying and displays the measuring point on the image. This allows operators to visually confirm measuring points and associate coordinate data with specific locations in the image, simplifying the complex process of matching separate measurements with their corresponding positions.
2Measurement precision
If conventional surveying methods are used to collect geographic data, then measurement accuracy is improved, but productivity decreases due to multiple required processes
Solution Approach 1:
The patent combines multiple functions (image pickup, distance measurement, coordinate measurement, and image processing) into a single integrated portable device. The image pickup unit captures images of objects, the distance measuring unit measures distances to specified points, the coordinate measuring unit acquires coordinate data, and the image processing unit matches images with measurement data to display measuring points on the image. This integration eliminates the need for separate surveying instruments and simplifies the measurement procedure while maintaining precision.
Solution Approach 2:
The patent enables continuous data collection by allowing operators to quickly capture images, specify measuring points on the displayed image, and automatically associate coordinate data with those points. The image processing unit continuously matches images with measurement results, enabling rapid sequential measurement of multiple objects without interrupting the workflow. This continuous operation significantly improves productivity compared to conventional methods that require separate, discrete measurement steps.
3Device complexity
If portable distance measuring systems without image pickup devices are used, then device complexity is reduced, but ease of operation decreases due to inability to specify measuring points visually
Solution Approach 1:
The patent combines multiple functions (image pickup, distance measurement, coordinate measurement, and image processing) into a single integrated portable device. The image pickup unit captures images of objects, the distance measuring unit measures distances to specified points, the coordinate measuring unit acquires coordinate data, and the image processing unit matches images with measurement data to display measuring points on the image. This integration eliminates the need for separate surveying instruments and simplifies the measurement procedure while maintaining precision.
Solution Approach 2:
The patent introduces an image processing unit as an intermediary that bridges the gap between the captured image and the measurement data. This unit matches the image with the surveying result and displays the measuring point on the image, providing visual feedback to the operator. This intermediary component enables easy specification of measuring points by allowing operators to see exactly where measurements are being taken, greatly improving ease of operation.
