Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If satellite positioning systems are used to determine mobile device location, then position information can be obtained, but the signals received are weak and require sufficiently sensitive receivers
Solution Approach 1:
The patent introduces markers (QR codes, bar codes, or other machine-readable symbols) as intermediary objects that carry location information. Instead of relying solely on weak satellite signals, the mobile device captures images of these markers which provide position data directly, acting as a mediator between the satellite system and the mobile device for more reliable location determination.
2Measurement precision
If markers like QR codes are used to assist in communicating mobile device locations, then location information can be determined more accurately, but the system complexity increases
Solution Approach 1:
The patent makes the mobile device's camera and image processing capabilities serve multiple functions: capturing satellite signals, scanning markers for location information, and potentially other mobile device functions. This multi-functionality reduces the need for dedicated specialized components, thereby limiting the increase in system complexity while improving location accuracy.
