Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional switch control is used for Christmas lights, then the lighting control is simple and reliable, but users must physically approach the switch which reduces convenience and accessibility
Solution Approach 1:
The patent replaces the mechanical switch system with a voice recognition system. The voice-processing device receives voice commands through a voice-receiving module, processes them through a processor, and transmits control signals to the lighting control device, thereby eliminating the need for physical contact with switches and improving ease of operation.
2Ease of operation
If voice control is implemented for Christmas lights, then user convenience is improved, but the system becomes susceptible to surrounding noise and voice interference which reduces reliability
Solution Approach 1:
The patent pre-stores multiple voice fingerprints and multiple error-tolerant voice fingerprints in the memory unit before operation. When a voice command is received, the system compares it against these pre-stored templates to determine the intended command, thereby improving recognition accuracy and reducing susceptibility to noise interference.
Solution Approach 2:
The patent employs different biometric match thresholds for different types of voice fingerprints. Voice fingerprints have a first biometric match threshold while error-tolerant voice fingerprints have a second biometric match threshold that is higher than the first. This parameter adjustment allows the system to balance between precision and tolerance for variations in voice commands.
3Measurement precision
If double voice recognition means is implemented to enhance precision, then voice command recognition accuracy is improved, but the device complexity increases
Solution Approach 1:
The patent divides the voice recognition system into two distinct components: voice fingerprints for precise recognition and error-tolerant voice fingerprints for broader matching. This segmentation allows the system to handle different recognition scenarios with appropriate threshold levels, improving overall precision while organizing the complexity into manageable modules.
Solution Approach 2:
The memory unit serves multiple functions by storing both voice fingerprints and error-tolerant voice fingerprints. The voice-processing device uses the same comparison mechanism for both types of fingerprints, thereby achieving enhanced recognition precision without proportionally increasing device complexity.

AI summary
A voice-controlled lighting control system includes a voice-processing device, a lighting control device and a lighting module. The lighting control device is connected to the voice-processing device and the lighting module. The voice-processing device is built in with multiple voice fingerprints and multiple error-tolerant voice fingerprints. During operation, users utter a voice command to the voice-processing device, the voice-processing device compares the received voice command with the voice fingerprints or the error-tolerant voice fingerprints, and sends a control signal to the lighting control device to instruct the lighting module to emit light when finding that the voice command falls within a biometric match threshold of one of the voice fingerprints or the error-tolerant fingerprints. Given the double voice recognition using the voice fingerprints and the error-tolerant voice fingerprints, the precision in recognizing the voice command is enhanced and voice control over lighting can be achieved.
