Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent device control systems require complex procedures for intercommunication between mobile phones and devices, including network setup, which can lead to conflicts and inefficiencies, especially when controlling multiple devices simultaneously.
Innovation Solution
The system converts control instructions into audio signals that can be sent directly from a mobile terminal to intelligent devices, eliminating the need for a third-party device and allowing simultaneous control of multiple devices with improved efficiency and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network connection procedures are used for control instruction transmission, then communication between mobile phone and device is established, but the procedure becomes complex and time-consuming
Solution Approach 1:
The patent extracts the essential control instruction transmission function from the complex network connection procedure. By using audio signal transmission through the loudspeaker and microphone, it removes the need for APP-based network communication, router account input, and IP address assignment, thereby simplifying the control procedure while maintaining communication reliability
Solution Approach 2:
The patent replaces the electronic network communication system (APP, router, IP address assignment) with an acoustic communication system (loudspeaker, audio signal, microphone). This substitution eliminates the complexity of network setup procedures while enabling direct control instruction transmission between mobile phone and intelligent device
2Reliability
If third-party devices or APPs are used for control instruction transmission, then communication is enabled, but system cost increases
Solution Approach 1:
The patent extracts the core transmission function from the third-party APP system and implements it using built-in mobile phone components (loudspeaker, microphone). This eliminates the need for separate APP installation and configuration, reducing system complexity while maintaining transmission reliability
Solution Approach 2:
The patent makes the mobile phone's audio components (loudspeaker and microphone) serve dual purposes: their original function for audio output/input and the additional function for control instruction transmission. This multi-functionality eliminates the need for dedicated third-party devices or APPs, reducing system configuration complexity
3Reliability
If sequential control of multiple devices is used, then each device receives control instructions, but transmission efficiency decreases due to conflicts and queuing
Solution Approach 1:
The patent segments the control instruction transmission to each intelligent device independently through audio signals. Each device can receive and process control instructions simultaneously without interfering with others, eliminating the sequential queuing problem and improving transmission efficiency while maintaining reliable device control
Solution Approach 2:
The patent replaces the network-based sequential communication system with acoustic wave-based parallel communication. Audio signals can propagate to multiple devices simultaneously without the conflicts and queuing inherent in network protocols, thereby improving transmission efficiency while ensuring reliable control of each device
