Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional microphones are used to detect barks, then the device can receive sound signals from any direction, but it cannot distinguish between barks of the pet to be trained and other pets or environmental noise
Solution Approach 1:
The patent introduces bone conduction microphones as an intermediary detection mechanism. Instead of using traditional air-conduction microphones that capture all sounds equally, the bone conduction microphones detect vibrations transmitted through the pet's bone structure. This intermediary approach selectively captures only the vibrations from the佩戴ed pet's barks while filtering out environmental noise and other pets' barks, thereby resolving the contradiction between detection coverage and detection accuracy.
Solution Approach 2:
The patent replaces the traditional acoustic detection system (air-conduction microphones) with a mechanical vibration detection system (bone conduction microphones). By substituting the detection medium from air to bone structure, the system achieves selective detection capability. The bone conduction microphones detect mechanical vibrations transmitted through the pet's skeletal structure, which only occurs when the佩戴ed pet barks, thus eliminating false triggering from other sound sources.
2Measurement precision
If bone conduction microphones are used to accurately detect pet barks, then false triggering is reduced, but the device structure becomes more complex
Solution Approach 1:
The bone conduction microphone serves multiple functions simultaneously: it acts as both the detection element and the transmission medium. The microphone contacts the pet's bone structure directly, using the bone itself as both the vibration source and the transmission path. This multi-functionality reduces the need for additional isolation or amplification components that would otherwise be required in traditional acoustic detection systems, thereby limiting the increase in device complexity.
3Productivity
If electric shock stimulation is applied to train pets, then training effectiveness is improved, but safety risks increase
Solution Approach 1:
The patent implements a feedback control system where the microprocessor continuously monitors detection signals from the bone conduction microphones and adjusts the electric shock stimulation accordingly. The system provides real-time feedback by detecting when the pet stops barking and immediately ceasing the stimulation. This feedback mechanism ensures that stimulation is applied only when necessary and for the minimum required duration, thereby improving training effectiveness while minimizing safety risks.
