Baseboard Moisture Sensing With Perimeter Electrode Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moisture sensors are ineffective in detecting water damage until a significant amount of water floods the room, as they require water to reach the sensor's location, leaving undetected moisture issues until they become severe.
Innovation Solution
A baseboard moisture detection system with electrodes extending along its length, embedded within a moisture-absorbing material, which completes a circuit when contacted by conductive liquid, triggering a detector to alert for potential water damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional moisture sensors are placed in one location to detect water, then the sensor structure is simple, but the sensor cannot detect water until a significant amount floods the room
Solution Approach 1:
The detection system is segmented into multiple baseboards distributed around the room perimeter, each with its own electrodes. This segmentation allows water to be detected at multiple locations simultaneously, improving reliability without requiring a single complex centralized sensor system.
Solution Approach 2:
The detection approach transitions from a single-point detection (conventional sensor) to a distributed linear detection network along the room perimeter. By placing electrodes in multiple baseboards around the room, the system creates a dimensional expansion from 0D point detection to 1D perimeter detection, enabling earlier water detection.
2Area of stationary object
If a single moisture sensor is used in one location, then the device complexity is low, but the detection coverage is limited
Solution Approach 1:
The baseboards serve dual functions: they perform their traditional architectural function as room trim while simultaneously serving as detection elements with embedded electrodes. This multi-functionality allows the same structure to provide both aesthetic/structural value and detection coverage along the room perimeter.
Solution Approach 2:
The detection function is merged with the existing baseboard structure rather than being a separate component. By integrating electrodes into the baseboards that are already installed around the room, the system combines structural elements with sensing elements, expanding coverage without adding separate detection infrastructure.
3Loss of time
If electrodes are placed in baseboards with moisture absorbing material, then early water detection is enabled, but the baseboard structure becomes more complex
Solution Approach 1:
The moisture-absorbing material is pre-positioned around the electrodes within the baseboard structure, ready to immediately absorb and transport water upon contact. This preliminary arrangement of the absorbing material ensures that when water reaches the baseboard, detection occurs rapidly without delay, reducing loss of time.
Solution Approach 2:
The moisture-absorbing material acts as an intermediary between the water and the electrodes. It absorbs water from the environment and transports it to the electrode contact points, enabling detection at lower water levels than would be required for direct electrode contact, thus improving detection timing.
