Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual alignment methods are used to position the camera lens, then the device complexity is reduced, but the manufacturing precision and measurement precision of lens alignment deteriorate
Solution Approach 1:
A laser beam is introduced as an intermediary tool to establish a precise reference axis. The laser beam serves as a visual mediator that guides the alignment of the camera lens with the rotation axis, enabling high-precision alignment without requiring complex mechanical alignment mechanisms. The laser provides a clear, straight reference line that simplifies the alignment process while maintaining manufacturing precision.
Solution Approach 2:
The patent replaces complex mechanical alignment systems with an optical alignment system using a laser beam. Instead of relying on mechanical guides, rails, or adjustment mechanisms, the invention uses light as a reference to define the rotation axis and align the camera lens, thereby reducing mechanical complexity while improving alignment precision.
2Reliability
If the camera lens is not precisely aligned with the rotation axis, then the device complexity is reduced, but the reliability of panorama image stitching deteriorates
Solution Approach 1:
The laser beam acts as a continuous reference mediator throughout the panorama capture process. By maintaining the laser alignment as a fixed reference, the system ensures that the camera lens remains properly positioned relative to the rotation axis across multiple rotation and tilting angles, guaranteeing reliable image stitching without requiring complex active correction mechanisms.
Solution Approach 2:
The alignment of the camera lens with the rotation axis is performed in advance using the laser beam before the actual panorama capture begins. This preliminary alignment action ensures that all subsequent images are captured from the correct geometric position, eliminating the need for complex real-time alignment adjustments during the capture process and ensuring reliable stitching.
3Area of stationary object
If multiple rotation and tilting angles are used to capture panorama images, then the area of coverage is improved, but the difficulty of detecting and measuring lens position deteriorates
Solution Approach 1:
The laser beam provides a fixed reference mediator that remains constant throughout multiple rotation and tilting movements. This intermediary reference allows the system to capture images at various angles while maintaining a known, fixed relationship between the camera lens and the rotation axis, making it easier to detect and measure lens position despite the increased coverage area.
Solution Approach 2:
The system uses the laser alignment as a feedback reference to monitor and maintain lens position accuracy. By continuously referencing the laser beam during rotation and tilting operations, the system can detect deviations and ensure the lens remains properly positioned, simplifying position detection even when capturing images at multiple angles for extended panorama coverage.
