Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple smart home devices are activated simultaneously to provide convenient home automation, then the convenience and functionality of the smart home system is improved, but the surge current superposition causes harm to devices and cables
Solution Approach 1:
The control device calculates the time interval before activating devices, determining the optimal delay based on surge current parameters. This preliminary calculation ensures that devices are activated in a sequence that prevents surge current superposition, thereby protecting devices and cables while maintaining smart home convenience
Solution Approach 2:
The system dynamically adjusts the time interval between device activations based on the specific surge current parameters of each device. Rather than using a fixed delay, the control device calculates optimal intervals in real-time, adapting the activation sequence to the electrical characteristics of the connected devices
2Reliability
If devices are activated with time intervals to reduce surge current superposition, then the safety of the smart home system is improved, but the complexity of device control increases
Solution Approach 1:
The control device serves as an intermediary between the user and the smart home devices. It automatically calculates and manages the activation time intervals based on surge current parameters, shielding users from the complexity of surge current management while ensuring safe device operation
Solution Approach 2:
The control device autonomously determines the optimal time intervals by retrieving surge current parameters from device information and performing calculations without user intervention. This self-service approach simplifies the user interface while maintaining system safety
3Reliability
If the time interval between device activations is increased to prevent surge current superposition, then the safety of cables and devices is improved, but the response time of the smart home system increases
Solution Approach 1:
The system optimizes the time interval parameter by calculating it based on surge current parameters rather than using a conservative fixed value. This parameter adjustment ensures the minimum necessary delay is applied, preventing surge current superposition while minimizing the impact on system response time

AI summary
A device control method is disclosed. When a first device and a second device are required to perform actions, a first instruction is sent to the first device, and a second instruction is sent to the second device after a first time interval; and when the first device, the second device, and a third device are required to perform actions, the first instruction is sent to the first device, the second instruction is sent to the second device after the first time interval, and a third instruction is sent to the third device after a second time interval, where the second time interval is greater than the first time interval, so that the third device performs a third action after a delay.
