Solution Overview
Problem
Existing smart cleaning devices face complex wiring and structural issues due to separately installed sensors for parameter measurement, occupying space and requiring large product sizes, especially when using integrated all-in-one sensor modules.
Innovation Solution
A sensor module design integrating multiple sensors within interconnected chambers on a single main body, with a pressure sensor in one chamber and other sensors in another, using a baffle plate to prevent liquid contact and a circuit board for connection, reducing complexity and size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sensors are separately installed at different positions, then each sensor can detect its specific parameter, but the wiring becomes complex and the structure occupies more space
Solution Approach 1:
Multiple sensors (liquid level sensor, conductivity sensor, turbidity sensor, temperature sensor) are integrated into a single sensor module with a unified structure. The sensors share common components including a single air pipe for liquid level detection, a integrated housing, and a centralized circuit board for signal processing, eliminating the need for separate wiring for each sensor.
Solution Approach 2:
The sensor module serves multiple detection functions simultaneously through a single integrated unit. The air channel serves both as a liquid level detection medium and as a pathway for other sensors. The circuit board provides universal signal processing capabilities for all sensor types within the module.
2Reliability
If various sensors are independently installed, then each sensor functions independently, but the product size becomes larger
Solution Approach 1:
All sensor components are merged into a compact integrated module. The housing contains all sensors in a space-efficient arrangement, with the air channel serving multiple purposes. The circuit board is integrated within the same housing, eliminating the need for separate mounting spaces for each sensor.
3Device complexity
If an all-in-one sensor module is used, then the structure is simplified, but the module needs to be disposed in chambers at different positions making the integrated structure complex
Solution Approach 1:
The sensor module utilizes three-dimensional spatial arrangement within the housing to accommodate multiple sensors at different positions and orientations. The air channel is positioned to serve sensors at various depths and locations, allowing the integrated module to maintain adaptability for different detection positions while keeping the overall structure unified.

AI summary
A sensor module includes a plurality of sensors having a first sensor and one or more second sensors, a main body having a first chamber and a second chamber, a circuit board connected to the plurality of sensors, and a housing covering the circuit board. The first sensor is a pressure sensor. One end of the first chamber allows a liquid to flow in. The one or more second sensors are installed in an other end of the first chamber. The second chamber is adjacent the other end of the first chamber and intersects with the first chamber. The second chamber has a hole provided on a side of the second chamber and a baffle plate arranged in the second chamber. The hole accommodates a part of the pressure sensor. The baffle plate is arranged along an extension direction of the second chamber and is adjacent the hole.
