Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If auxiliary determining units are added to each signal area, then positioning accuracy and success rate are improved, but device complexity increases
Solution Approach 1:
The patent divides the signal coverage area into multiple signal areas, with each area containing an auxiliary determining unit. This segmentation allows each unit to independently determine positioning effectiveness in its specific area, improving overall positioning accuracy without requiring every unit to process all data.
Solution Approach 2:
The auxiliary determining unit acts as an intermediary component that receives positioning data from the wireless positioning module and determines its effectiveness. This mediator approach allows the main positioning system to remain simple while adding specialized units only where needed for verification.
2Reliability
If auxiliary determining units are added to each signal area, then positioning success rate is improved, but manufacturing cost increases
Solution Approach 1:
The auxiliary determining unit is designed as a simple, low-cost component with relatively basic processing capabilities. By using inexpensive hardware and software-based determination logic, the patent achieves high positioning success rates without significant cost increases, making the solution economically viable.
3Device complexity
If positioning data is processed without auxiliary determination, then device complexity is reduced, but positioning time increases
Solution Approach 1:
The auxiliary determining unit performs preliminary determination of positioning data effectiveness before the main positioning processing begins. This preliminary action filters out ineffective data early, preventing time-consuming processing of useless information and reducing overall positioning time despite the added component.

AI summary
This application provides a positioning method and an electronic device, and relates to the field of terminal technologies. In this application, an initial location of a positioned second electronic device can be quickly determined based on an auxiliary determining signal transmitted between an auxiliary determining unit preconfigured in a first electronic device and an auxiliary determining unit preconfigured in the second electronic device, to effectively improve a positioning success rate, and greatly shorten positioning time of the initial abnormal location. The method is applied to the first electronic device. The first electronic device includes a first wireless positioning module, an auxiliary determining unit is disposed in each of M signal areas of the first wireless positioning module, an optical angle of the auxiliary determining unit is less than or equal to a signal coverage angle of a corresponding signal area, and M is a positive integer. The method includes: receiving, via a first auxiliary determining unit, the auxiliary determining signal sent by the second electronic device; and determining, based on the auxiliary determining signal, effectiveness of target positioning data obtained by the first electronic device via the first wireless positioning module.
