Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic animal traps experience inconsistent shock output due to varying battery life, leading to a shorter battery lifespan and less reliable animal kills, as they deliver either excessive or insufficient power based on battery capacity.
Innovation Solution
A system that includes a controller with a shock cycle module to determine battery capacity and adjust the shock enable time, ensuring a consistent shock output voltage by controlling the primary current through a transformer, independent of battery life, using a charge pump, voltage adjuster, and field-effect transistor to maintain a consistent shock voltage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trap uses fixed shock duration based on initial battery voltage, then the shock output is consistent at the start, but the shock power becomes insufficient as batteries degrade
Solution Approach 1:
The patent applies dynamics by making the shock duration variable rather than fixed. The controller dynamically adjusts the shock enable time based on real-time battery voltage detection. When battery voltage is high (fresh batteries), the shock duration is shortened; when battery voltage is low (degraded batteries), the shock duration is extended. This dynamic adjustment ensures consistent shock energy delivery throughout the battery lifecycle, resolving the contradiction between maintaining reliable kills and extending battery lifespan.
Solution Approach 2:
The patent changes the parameter of shock duration based on battery state. By detecting battery voltage and adjusting the shock enable time accordingly, the system modifies the operational parameters to compensate for battery degradation. This parameter change approach allows the trap to maintain effective shock output regardless of battery age, addressing the reliability issue without prematurely exhausting battery capacity.
2Reliability
If the trap extends shock duration to compensate for low battery power, then animal kills remain reliable, but battery capacity is depleted faster
Solution Approach 1:
The system dynamically adjusts shock duration based on real-time battery voltage detection. When batteries are fresh and provide high voltage, the shock duration is reduced, conserving battery capacity. When batteries are depleted and provide low voltage, the shock duration is extended to maintain sufficient shock energy for reliable kills. This dynamic balancing act resolves the contradiction between maintaining kill reliability and minimizing battery capacity consumption.
Solution Approach 2:
The patent implements feedback by continuously monitoring battery voltage and using this information to adjust shock duration. The controller detects the battery state and feeds this information back into the shock control mechanism, creating a closed-loop system that optimizes energy usage. This feedback mechanism ensures that the trap maintains effective performance while minimizing unnecessary energy consumption, resolving the contradiction between reliable kills and battery conservation.
3Duration of action of stationary object
If the trap uses shorter shock duration with fresh batteries, then battery lifespan is extended, but the shock power may be insufficient when batteries are old
Solution Approach 1:
The patent makes shock duration dynamic rather than fixed. With fresh batteries providing high voltage, the system uses shorter shock durations that conserve battery capacity, extending overall battery lifespan. With old batteries providing low voltage, the system automatically extends shock duration to compensate for the reduced voltage, maintaining sufficient shock power for effective animal kills. This dynamic adjustment resolves the contradiction between extending battery lifespan and maintaining adequate shock power throughout the battery lifecycle.
