Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing network configuration and registration process for smart home devices is complex and time-consuming, leading to a poor user experience when controlling these devices.
Innovation Solution
A method that allows an electronic device to control a home device using ultra-short-haul antennas, where the device broadcasts messages to detect a preset condition, sends a second message to use the first antenna for obtaining a random code, and accesses the wireless local area network for configuration and control, simplifying the control process and enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the home device uses a long transmitting distance antenna (second antenna) for broadcasting, then the broadcasting range is improved, but the security of data transmission deteriorates
Solution Approach 1:
The patent divides the antenna system into two distinct segments: a first antenna with short transmitting distance for secure data transmission and a second antenna with long transmitting distance for wide broadcasting range. This segmentation allows each antenna to fulfill different functional requirements independently, resolving the contradiction between security and coverage.
Solution Approach 2:
The patent applies different quality characteristics to different antennas: the first antenna is optimized for short-range secure communication with restricted transmission distance, while the second antenna is optimized for long-range broadcasting. This local differentiation of quality attributes enables simultaneous achievement of security and wide coverage.
2Reliability
If the home device requires network configuration and registration before control, then the system reliability is improved, but the operation complexity and time consumption increase
Solution Approach 1:
The patent performs preliminary actions by having the home device broadcast its identifier and establishing a connection through ultra-short-haul communication before formal network configuration and registration. This preliminary connection establishment enables control operations to proceed without waiting for complete network setup, reducing operation complexity while maintaining system reliability through subsequent proper registration.
Solution Approach 2:
The patent introduces an intermediary mechanism using ultra-short-haul communication as a temporary channel that enables control operations before formal network registration. This intermediary communication path allows the electronic device to interact with the home device immediately, bypassing the need for immediate network configuration while ensuring reliable communication.
3Ease of operation
If the home device uses ultra-short-haul communication for control, then the operation simplicity is improved, but the broadcasting range is reduced
Solution Approach 1:
The patent segments the communication function into two parts: ultra-short-haul communication for simplified control operations and long-range broadcasting for wide area notification. The electronic device can choose the appropriate communication mode based on the operational context, achieving both simplicity and wide coverage.
Solution Approach 2:
The home device is designed with multi-functionality, supporting both ultra-short-haul communication for direct control and long-range broadcasting for wide area notification. The electronic device similarly supports multiple communication modes, enabling it to adapt to different operational requirements and achieve universal compatibility.

AI summary
A home device control method and a device. When detecting that the home device meets a preset condition, the electronic device sends a second message to the home device, to indicate the home device to use a first antenna and to indicate to obtain a random code; receives the random code sent by the home device by using the first antenna; accesses a wireless local area network based on the random code, and obtains configuration information including an interface element of a control page and a control instruction that are used to control the home device; and displays the control page and interacts with a user by using the control page, and sends the control instruction to the home device through the wireless local area network, to control the home device.
