Animal Shock Collar Water Sensor Safety Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dog collars designed to prevent attacks by delivering an electric shock to an attacking dog are not effectively prevented from functioning when wet, which can lead to accidental shocks and reduced reliability.
Innovation Solution
A collar with a water sensor that detects moisture and prevents the power supply from creating a potential difference between electrodes, along with a remote control for managing shock states and a rechargeable battery with a digital display, LEDs for visibility, and a camera for recording or transmitting video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the collar delivers electric shock to stop dog attacks, then the safety of dogs and owners is improved, but the risk of accidental shock when wet increases
Solution Approach 1:
The water sensor is activated before the power supply operates, detecting the presence of water and preventing the power supply from creating a potential difference between electrodes. This preliminary detection action prevents accidental shocks before they can occur.
Solution Approach 2:
The water sensor acts as an intermediary between the environment (water presence) and the power supply system. It mediates by detecting water and signaling the electronics unit to prevent operation, thereby blocking the harmful effect of accidental shock.
2Reliability
If the collar includes water sensor and control mechanisms, then the safety when wet is improved, but the device complexity increases
Solution Approach 1:
The water sensor automatically detects water presence and triggers the prevention mechanism without requiring user intervention. The system serves itself by monitoring its own operational conditions and taking appropriate preventive action.
Solution Approach 2:
The water sensor provides feedback to the electronics unit about the presence of water, which then adjusts the power supply operation accordingly. This feedback loop ensures safety while maintaining a relatively simple control structure.

AI summary
An anti-attack shock collar is a collar for an animal. The anti-shock collar includes an electronics unit; a power supply operable to create a potential difference between a first and a second terminal; at least one flexible strap secured at one position along its length to the electronics unit; and a water sensor. The flexible strap includes first and second electrodes which are exposed or partially exposed on the exterior of the collar and are electrically connected to the first and second terminals of the power supply respectively. The water sensor detects the presence of water on a portion of the collar. If water is detected on the portion of the collar, the water sensor causes the electronics unit to prevent the power supply from being operated to create a potential difference between the first and second electrodes.
