Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the controller of the smart appliance has varied functions to meet user needs, then the ease of operation and adaptability are improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies universality by enabling a single controller to perform multiple functions through software-based command processing. The controller can handle various user commands (audio, video, keyboard input) and convert them into different appliance control commands, allowing one hardware unit to replace multiple specialized controllers, thereby reducing manufacturing costs while maintaining versatility.
Solution Approach 2:
The patent utilizes parameter changes by transforming different input command types (audio commands, video commands, keyboard commands) into standardized control commands that can be processed uniformly. The controller adjusts its processing parameters based on the input type, enabling flexible adaptation to various user needs without requiring different hardware configurations.
2Reliability
If the controller processes all commands locally without backup, then the device complexity is reduced, but the reliability decreases
Solution Approach 1:
The patent applies preliminary action by backing up control commands and their corresponding appliance commands in the memory device before execution. This pre-backup mechanism ensures that commands are preserved and can be retrieved if needed, enhancing reliability without significantly increasing system complexity during operation.
Solution Approach 2:
The system implements feedback by storing the relationship between user commands and appliance control commands in memory. This creates a reference mechanism that allows the system to verify and retrieve command mappings, improving reliability through a feedback loop that confirms command processing accuracy.
3Measurement precision
If audio or video recognition is performed locally only, then the speed of command processing is improved, but the measurement precision deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the command recognition process into two parts: initial local recognition for speed, and secondary server-based recognition for precision. The smart mobile device first attempts local recognition, and only if that fails does it communicate with the server system for advanced recognition, thus segmenting the processing load to balance speed and accuracy.
Solution Approach 2:
The patent uses an intermediary approach by introducing a server system as a mediator when local recognition fails. The server system acts as an intermediate processing layer that provides advanced recognition capabilities, bridging the gap between local processing limitations and the need for high recognition accuracy.

AI summary
A smart appliance control system includes a memory device, a connecting interface device and a central controlling device. The central controlling device converts a control command into at least one appliance control command. A first smart mobile device receives a user command and processes it as a control command. The connecting interface device receives the control command and sends it to the central controlling device. The central controlling device executes one of operations as follows according to the control command: (A) A corresponding action is executed, and the control command and information of the corresponding action are backed up in a memory device; and (B) the control command is converted into the appliance control command and sent to at least one appliance, and the control command, the appliance control command and the information of the corresponding action are backed up in the memory device.
