Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed frequency electromagnetic signal is used to deter birds, then the device is simple to operate, but birds may adapt to the frequency and return to land and nest in unwanted areas
Solution Approach 1:
The patent applies dynamics by making the electromagnetic signal frequency variable rather than fixed. The controller dynamically adjusts the frequency of the electromagnetic signal at predetermined intervals to prevent bird adaptation. This resolves the contradiction by maintaining high deterrence effectiveness through frequency variation while keeping the device operationally manageable through automated control.
Solution Approach 2:
The patent implements parameter changes by systematically varying the frequency parameter of the electromagnetic signal over time. The controller changes the frequency at predetermined intervals, creating a dynamic signal that birds cannot adapt to. This parameter variation maintains reliability in deterrence while the automated system manages the complexity of frequency control.
2Reliability
If high power electromagnetic signals are used to deter birds, then the deterrence effectiveness improves, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by transmitting electromagnetic signals in pulses rather than continuously. The controller transmits signals at predetermined intervals, creating a periodic pattern that maintains deterrence effectiveness while significantly reducing overall energy consumption compared to continuous high-power transmission.
Solution Approach 2:
The patent uses dynamics by varying the power level of the electromagnetic signal over time. The controller adjusts power transmission dynamically, using higher power only when needed for deterrence and lower power during non-critical periods, thereby reducing average energy consumption while maintaining effective bird repellent performance.
3Object-affected harmful factors
If electromagnetic signals are used to deter birds, then bird damage and disease exposure are reduced, but the device complexity increases compared to simple physical barriers
Solution Approach 1:
The patent applies mechanics substitution by replacing physical bird deterrent devices (such as spikes or nets) with an electromagnetic field-based system. This substitution eliminates direct physical contact with birds, reducing damage and disease exposure to workers, while the complexity is managed through automated frequency and power control rather than complex mechanical structures.
