New Anti-Drowning Pool Alarm ODM Functional Breakthrough Design

Project Background & Customer Core Requirements

Pool safety has become a key demand for global residential swimming pools, villa courtyards and private water scene facilities. Every year, accidental drowning of children and pets caused by unattended swimming pools occurs frequently, and the market has extremely high demand for intelligent pool safety early warning equipment.

Although traditional pool alarm products on the market are diverse, they have prominent common pain points: infrared beam sensors are easily interfered by sundries and water splashes; visual camera solutions are restricted by strong sunlight and water fog, and face user privacy disputes; wave sensor alarms have extremely high false positive rates and poor anti-interference ability, resulting in unstable actual use effect and unable to meet reliable safety monitoring standards.

Entrusted by the customer, BL carried out breakthrough functional design optimization and full-process customized development for the new generation of pool anti-drowning alarm. Focusing on solving the industry pain points of false alarm, missed alarm and poor environmental adaptability of traditional products, we developed a high-stability floating pool alarm based on water body disturbance + water sound dual detection principle, realizing accurate early warning of falling objects in the pool and effectively preventing drowning accidents of children and pets.

Product Core Design & Technical Breakthrough

Aiming at the defects of mainstream competitive products, we abandoned the single infrared, camera and wave sensing schemes in the market, and adopted an innovative water body disturbance + water sound dual intelligent detection algorithm, matched with large disc floating body structure design, comprehensively improving product stability and anti-interference ability.

Dual Detection Principle Innovation

The product integrates water wave disturbance sensing and water splash sound acquisition technology. It can accurately identify the characteristic signals of objects falling into water, effectively filter invalid interference such as natural wind waves, water surface splashes and environmental noise, and solve the long-standing industry problem of high false alarm rate of traditional pool alarms.

Large Disc Floating Body Structure Design

The overall floating body adopts a large-diameter disc structure, which has stronger water surface stability, is not easy to shake and deflect with wind and waves, ensures the sensor remains horizontal and stable for a long time, and guarantees continuous and accurate monitoring of pool water surface status.

Intelligent Algorithm Threshold Self-Adaptation

Through a large number of scene simulation experiments, we calibrate the sensing threshold, realize intelligent distinction between conventional water surface fluctuation and object falling water impact signals, perfectly balance missed alarm rate and false alarm rate, and greatly improve monitoring accuracy.

Full Waterproof & Outdoor Weather Resistance Design

The whole machine adopts IP68 fully enclosed waterproof structure, with optimized sealing ring aging resistance design. It adapts to outdoor open-air exposure, high temperature sun exposure, low temperature cold resistance and other harsh pool environment, achieving long-term stable outdoor operation.

Low Power Wireless Intelligent Design

Optimize dormant power consumption and wireless radio frequency transmission scheme, support long-distance wireless signal transmission and wall penetration, with ultra-low standby power consumption, effectively extending battery cycle life, reducing later maintenance frequency.

DFMEA Risk Control & Industry Pain Point Optimization

Targeting the complex outdoor pool environment and long-term unattended working state, we completed comprehensive risk identification and targeted technical optimization for traditional product defects:

- Wind & Water Splash Interference Risk: Dual detection of water disturbance + water sound filters invalid wave signals, completely solving the false alarm problem of infrared and single wave sensors.

- Light & Fog Environmental Interference: Abandon camera visual recognition, no longer affected by strong sunlight, water fog and light darkness, with stronger environmental adaptability.

- Floating Body Instability Risk: Large disc floating body structure improves wind and wave resistance, avoiding monitoring deviation caused by equipment shaking.

- Water Ingress & Aging Failure Risk: IP68 full waterproof + sealing ring anti-aging design, preventing water ingress damage and outdoor aging failure.

- Short Battery Life & Weak Signal Risk: Low-power dormancy algorithm + optimized RF penetration performance, realizing long battery life and stable signal transmission.

Prototype Development & Sample Assembly Process

Based on the finalized innovative scheme, we completed rapid prototype development and verification through full-process self-developed capabilities:

First, complete structural shell rapid prototyping via 3D printing, verify the floating body fitting degree, structural stability and overall waterproof assembly fit. Then complete hardware circuit board sample production, sensor welding and debugging, and assemble the complete functional prototype. After repeated assembly fitting and structural optimization, eliminate assembly interference and hidden water ingress risks, and lay a solid foundation for subsequent formal mold opening and mass production.

Multi-Scenario Professional Verification & Functional Testing

In order to verify the product’s monitoring accuracy, environmental adaptability and long-term reliability, we conducted comprehensive simulation scene tests, and all indicators meet and exceed design standards:

- Sensor Algorithm Calibration Test: Simulate falling water scenes of objects with different weights, match with wind wave interference simulation, continuously optimize and adjust algorithm thresholds to realize accurate identification of real danger signals and effective filtering of invalid interference.

- IP68 Waterproof & Aging Test: Long-term immersion pressure resistance test and sealing ring aging test to ensure no water ingress and stable sealing performance in long-term underwater and humid environment.

- RF Wireless Performance Test: Verify wireless transmission distance and wall penetration ability to ensure stable alarm signal output in different pool layouts and indoor and outdoor environments.

- Low Power Consumption & Battery Life Test: Test dormant operating current, calculate and optimize battery cycle life, achieve ultra-low power standby and long-term uninterrupted monitoring.

- High & Low Temperature Aging Test: Simulate outdoor high-temperature sun exposure and low-temperature cold environment of the pool to verify the equipment’s operating stability under extreme weather conditions.
