Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If electrical stimulation is delivered directly from transformer output without precise control, then the system is simple to operate, but voltage control precision is poor leading to under- or over-correction
Solution Approach 1:
The patent implements feedback control by measuring the actual voltage delivered to the pet and comparing it with the desired voltage level. The system adjusts the transformer duty cycle based on this feedback to maintain precise voltage control. This resolves the contradiction by introducing measurement and control mechanisms that ensure accurate voltage delivery while managing system complexity through automated feedback loops.
Solution Approach 2:
The patent employs dynamic voltage adjustment by varying the transformer duty cycle in real-time based on measured voltage levels and pet response. Rather than using fixed voltage output, the system dynamically adapts the stimulation parameters to maintain optimal control precision. This dynamic approach enables precise voltage control while the automation reduces the operational burden on the user.
2Object-affected harmful factors
If fixed voltage levels are used without adjustment, then the device is easy to manufacture, but it causes under- or over-correction increasing pet stress
Solution Approach 1:
The system continuously monitors voltage delivery and pet response, adjusting stimulation levels in real-time to prevent both under-correction and over-correction. This feedback mechanism reduces harmful effects by ensuring stimulation remains within optimal ranges, while the automated control minimizes the complexity burden on operation.
Solution Approach 2:
The patent changes voltage parameters dynamically based on measured conditions and pet response. By adjusting voltage levels, pulse widths, and duty cycles in real-time, the system adapts to prevent harmful effects while maintaining effective training. This parameter adaptation reduces stress by avoiding excessive stimulation while ensuring sufficient correction.
3Reliability
If voltage levels are not monitored, then the system is simple to operate, but delivery effectiveness cannot be determined
Solution Approach 1:
The system implements automatic monitoring and feedback to determine delivery effectiveness by measuring actual voltage delivered and comparing it with expected values. This ensures reliable operation by confirming successful charge delivery to the pet. The automated nature of this monitoring maintains ease of operation while significantly improving reliability of stimulation delivery.
Solution Approach 2:
The system performs self-monitoring and self-adjustment of voltage delivery parameters to ensure effective stimulation. By automatically detecting delivery effectiveness and adjusting parameters as needed, the system maintains reliable operation without requiring constant user intervention, thus preserving ease of operation while enhancing reliability.
