Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a plurality of related art image acquisition devices are arranged in an array to perform tomographic measurement, then measurement coverage is improved, but the number of devices and system complexity increase
Solution Approach 1:
The patent divides the measurement system into two functional segments: a movable image acquisition device that captures images at multiple positions, and a stationary control device that coordinates the movement and processes data. This segmentation allows the measurement coverage to be expanded through movement rather than by adding multiple stationary devices, thereby reducing overall system complexity while maintaining comprehensive measurement capability.
Solution Approach 2:
The patent employs a movable image acquisition device that can dynamically change its position along the measurement object. This dynamic positioning capability allows a single device to cover multiple measurement positions that would otherwise require multiple stationary devices, thus improving measurement coverage while reducing the total number of devices needed in the system.
2Productivity
If multiple image acquisition devices are used to reduce measurement time, then productivity is improved, but device complexity and data processing burden increase
Solution Approach 1:
The patent implements preliminary action by having the movable image acquisition device capture images at multiple predetermined positions sequentially before data processing begins. The control device pre-coordinates the movement to predetermined positions and prepares the measurement sequence in advance, allowing efficient data processing afterward without requiring complex real-time coordination of multiple devices during measurement, thus improving productivity while managing system complexity.
3Device complexity
If the image acquisition device is made movable to reduce the number of devices, then device complexity is reduced, but measurement precision may deteriorate due to positioning requirements
Solution Approach 1:
The patent incorporates feedback mechanisms where the control device monitors and records the actual positions of the movable image acquisition device at each measurement point. This feedback information is used to accurately associate captured images with their corresponding spatial positions, ensuring measurement precision is maintained despite the device's movement. The system compensates for positioning variations through this feedback-based position tracking and data correlation approach.
