Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If satellite positioning system or wireless network positioning is used to steer energy towards receiver device, then beam steering capability is achieved, but positioning accuracy deteriorates due to uneven earth surface and distance errors
Solution Approach 1:
The patent introduces an intermediary mechanism (image capturing unit and image processing) between the transmitter device and receiver device to determine relative position and orientation. Instead of relying directly on satellite positioning or wireless network positioning, the system captures images of the receiver device, processes these images to extract position and orientation information, and uses this information for beam steering. This intermediary approach overcomes the inaccuracies of direct positioning methods by providing more precise relative positioning data through visual measurement.
2Measurement precision
If image analysis is used to determine receiver device orientation, then polarization alignment accuracy is improved, but device complexity increases due to image capturing and processing requirements
Solution Approach 1:
The patent applies multi-functionality by using the image capturing unit for multiple purposes: it captures images not only for determining the receiver device's position and orientation for beam steering, but also potentially for tracking movement and maintaining alignment over time. This universal approach consolidates multiple functions into a single system component, reducing overall system complexity despite the added capability for precise polarization alignment.
