Humidity Sensor Face Plate Design for Faster Wall-Mounted Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Humidity sensors recessed within walls for aesthetic reasons often have slower response times due to reduced airflow, hindering effective humidity control and making them sensitive to air currents.
Innovation Solution
A face plate with an extended portion creates a secondary space to enhance airflow over the humidity sensor, improving measurement accuracy and response time, while concealing the sensor to maintain a desired aesthetic appearance, similar to a light switch assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the humidity sensor is recessed within the wall for aesthetic appearance, then the visual appearance is improved, but the response time increases and measurement accuracy decreases
Solution Approach 1:
The face plate extends in a direction perpendicular to the wall surface, creating a third-dimensional structure that protrudes from the wall. This extended portion forms a secondary space that captures humid air and directs it toward the recessed sensor, allowing the sensor to remain aesthetically recessed while functionally exposed to ambient humidity through the three-dimensional airflow path
2Shape
If the humidity sensor is recessed within the wall, then the aesthetic appearance is improved, but the measurement accuracy of ambient humidity decreases
Solution Approach 1:
The extended portion of the face plate acts as an intermediary structure that captures humid air from the ambient environment and channels it through the secondary space to the recessed sensor. This intermediary element bridges the gap between the sensor's recessed position and the need for accurate ambient humidity measurement, allowing the sensor to measure humidity without being directly exposed
3Loss of time
If the humidity sensor protrudes from the wall, then the response time is improved, but the aesthetic appearance deteriorates
Solution Approach 1:
The face plate is segmented into two functional zones: the main body that remains flush with the wall for aesthetic purposes, and the extended portion that protrudes to capture humid air. This segmentation allows different parts of the same structure to serve opposing functions - the recessed portion maintains aesthetics while the extended portion ensures rapid humidity detection
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances the accuracy and speed of humidity measurements, reducing response time to detect unacceptable humidity levels and improving the effectiveness of humidity control systems.
Implementation Method 1
The extended portion can be configured to direct a flow of humid air over the humidity sensor
Data Source
AI summary
A humidity monitoring system mountable to a wall has a housing for receiving a humidity sensor. A face plate having an extended portion can be mounted over the housing such that the extend portion is positioned adjacent to the humidity sensor. The extended portion defining a secondary space within which humid air can be pass proximate to the humidity sensor to improve the monitoring of the ambient humid air.
