Under-Sink Waterproof Mat with Sensor-Based Leak Detection and Alert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of products available to address water damage and associated issues such as mold growth in under sink cabinets, which can lead to significant property loss and health hazards from water stains, mildew, and mold.
Innovation Solution
A waterproof, mildew-resistant mat with a built-in battery-powered sensor and speaker that detects water leakage and alerts the user through beeping noises, featuring a flexible rubber surface, a sturdy synthetic lip to contain water, and anti-splash and anti-slip layers to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof mat is installed in the under sink cabinet, then water damage prevention is improved, but device complexity increases due to adding sensor and alert systems
Solution Approach 1:
The patent combines multiple functions into a single integrated mat system: the waterproof mat itself, water detection sensors, alert mechanisms (visual and audible), and battery power supply are merged into one unified device. This allows the system to provide both passive water protection and active leak detection/alerting without requiring multiple separate components, thereby improving reliability while managing device complexity through functional integration.
2Measurement precision
If a battery-powered sensor is added to detect water leakage, then measurement precision is improved, but use of energy increases
Solution Approach 1:
The sensor system operates in a periodic manner rather than continuously. The battery-powered sensor detects water leakage and triggers alerts only when needed, rather than requiring constant power consumption for continuous monitoring. This periodic operation mode maintains measurement precision for detecting water presence while significantly reducing overall energy consumption from the battery, allowing the system to function effectively without requiring frequent battery replacements.
3Object-affected harmful factors
If an elevated lip is added to contain water, then object-affected harmful factors are reduced, but device complexity increases
Solution Approach 1:
The elevated lip is constructed from flexible rubber material that forms a simple yet effective barrier to contain and redirect water. This flexible lip structure provides physical containment of water without requiring complex mechanical components, rigid structures, or multiple parts. The simplicity of the flexible lip design minimizes structural complexity while effectively reducing water damage by preventing water from reaching sensitive areas of the under sink cabinet.

AI summary
The cabinet-protecting waterproof mat is specifically designed to prevent water damage for sink base cabinets and to alert the owner when there is water leakage. The main mat is waterproof, mildew resistant, and catches water that may have dripped or leaked on the main pad, surrounded by an elevated lip. The mat has a battery-powered sensor to detect when water is collecting on the mat. Furthermore, the sensor is connected to a speaker to emit beeping noises when water is detected or if the battery needs replacing. The volume of said beeping can be set to high or low, and the power can be turned on or off by corresponding buttons.
