Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical connections are used to control terminal devices, then control reliability is improved, but control flexibility and remote operation capability deteriorate
Solution Approach 1:
The patent introduces a mobile phone as an intermediary device between the user and the terminal device. The mobile phone establishes wireless connections (WiFi, Bluetooth) to communicate with terminal devices, enabling remote control without direct physical connection. This intermediary approach maintains control reliability through protocol verification while achieving remote operation flexibility.
Solution Approach 2:
The patent replaces mechanical physical connections with wireless communication protocols. Instead of using cables or direct physical links to control terminal devices, the system uses wireless signals (WiFi Direct, Bluetooth) transmitted through the mobile phone, eliminating the need for physical proximity while maintaining control effectiveness.
2Measurement precision
If dedicated remote controllers are used for each household appliance, then control precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the mobile phone a universal remote control that can operate multiple types of terminal devices (computers, televisions, air conditioners, refrigerators) through a single application. The system detects terminal device types automatically and adapts control protocols accordingly, eliminating the need for multiple dedicated remote controllers while maintaining precise control for each device type.
Solution Approach 2:
The system dynamically changes control parameters based on the detected terminal device type. When a terminal device is detected, the system identifies its type (computer, TV, appliance) and adjusts the control protocol, communication method, and interface parameters accordingly, enabling precise control adaptation without requiring separate dedicated controllers for each device.
3Reliability
If control protocols are verified for compatibility, then control reliability is improved, but operation time increases
Solution Approach 1:
The patent performs control protocol compatibility verification as a preliminary action before executing actual control operations. The mobile phone detects the terminal device type and verifies protocol compatibility in advance, ensuring reliable control communication. This preliminary verification prevents failed control attempts and establishes a stable connection foundation for subsequent operations.
Data Source
AI summary
A method, device, and system for controlling a terminal device are disclosed. The method includes: traversing, by the intelligent device, pre-stored correspondences between control triggering requests and terminal devices in response to a control triggering request, to search multiple terminal devices for a target device corresponding to the control triggering request; determining whether a control protocol of the intelligent device is consistent with a control protocol of the target device when the intelligent device and the target device are in a connected state; when the control protocol of the intelligent device is consistent with the control protocol of the target device, receiving an input instruction and performing operation control on the target device according to the input instruction. By means of this application, effective intelligent control by an intelligent device on a terminal device such as a computer is implemented, and a requirement of a user is satisfied.
