Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If all electronic devices are upgraded with accurate locating circuits, then location accuracy is improved, but device cost increases significantly
Solution Approach 1:
The patent introduces an annotation device as an intermediary component. Instead of requiring every electronic device to have UWB locating circuits, the annotation device serves as a mediator between the mobile device and the electronic device being controlled. The annotation device receives positioning information from the mobile device and transmits control signals to the electronic device, enabling location-based control without upgrading all devices.
Solution Approach 2:
The patent extracts the UWB locating circuit functionality from the electronic device and places it in the mobile device instead. By moving the locating circuit to the mobile device (which already exists in most smartphones) and using the annotation device as a relay, the system eliminates the need to upgrade expensive locating circuits in every electronic device while maintaining accurate location capability.
2Adaptability or versatility
If users manually select and control IoT devices from a list, then control functionality is complete, but user operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent implements self-service by having the system automatically identify and control the electronic device based on the mobile device's location and pointing direction. Instead of requiring users to manually search through device lists, the system uses the mobile device's inherent location services and direction sensors to automatically determine which electronic device should be controlled, making the control process intuitive and hands-free.
Solution Approach 2:
The patent performs preliminary actions by pre-configuring the annotation device with location information and establishing the communication pathway before the user needs control. The system pre-processes location data and device pairing information, so when the user points the mobile device at the electronic device, the control window can immediately appear without requiring manual selection or device discovery procedures.
3Productivity
If the control window appears immediately after pointing to the electronic device, then operation speed is improved, but location determination complexity increases
Solution Approach 1:
The patent segments the location determination process into distinct functional components: the mobile device handles location acquisition and direction measurement, the annotation device handles position annotation and communication relay, and the control system handles window management. This segmentation allows each component to perform its specific function efficiently, achieving fast control window appearance without overcomplicating the overall location determination system.

AI summary
This application provides a method and system for quickly popping up a control window for an electronic device, and a mobile device. The mobile device communicates wirelessly with an annotation device and a to-be-annotated electronic device. The mobile device includes a processor, a memory, a UWB label, a direction sensor, and a computer program. The computer program is stored in the memory, and when the computer program is executed by the processor, the mobile device is enabled to perform the following steps: receiving a first input after the mobile device moves to a location of the electronic device; recording a location of the mobile device in response to the first input, where the location of the mobile device is the location of the electronic device; and popping up, by the mobile device, a first control window for the electronic device after the mobile device moves to another location and points to the electronic device. According to the technical solutions provided in this application, the mobile device can control, by using the annotation device, an electronic device on which no UWB chip is installed. This improves user experience.
