Modular Ventilation Fan Sensor Mount for Flexible Air Volume Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ventilation fans require different sensors based on installation environments, leading to increased production and management costs due to the need for various sensor types and potential replacement of entire units when sensor types change.
Innovation Solution
A modular ventilation fan design with a body unit and interchangeable sensor modules, where the sensor module controller outputs detection information to the fan controller, allowing for flexible sensor configurations and reduced costs by enabling the use of common fan controller specifications across different sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different sensor types are used for different installation environments, then the ventilation fan can adapt to various environments, but the production cost and management cost increase
Solution Approach 1:
The sensor module is separated from the fan controller into an independent, interchangeable component. This allows the sensor module to be replaced based on installation environment requirements while keeping the fan controller unchanged, reducing production and management costs associated with creating multiple fan models.
Solution Approach 2:
The fan controller is designed with universal compatibility to work with different types of sensor modules. This enables a single fan controller model to serve multiple installation environments by simply changing the sensor module, thereby maintaining adaptability while reducing the need for multiple fan controller variants.
2Adaptability or versatility
If the sensor type must be changed after installation, then the ventilation fan can match the required sensor, but the entire ventilation fan must be replaced
Solution Approach 1:
The sensor module is designed as a separate, independently replaceable component from the fan controller. This segmentation allows users to replace only the sensor module when sensor type changes are needed, rather than replacing the entire ventilation fan, thereby improving ease of repair and reducing costs.
3Ease of manufacture
If a fixed sensor configuration is used in the ventilation fan, then the production cost is reduced, but the ventilation fan cannot be adapted to different installation environments
Solution Approach 1:
The fan controller is designed with universal compatibility to interface with different sensor module types. This allows a single fan controller design to support multiple installation environments through interchangeable sensor modules, maintaining low production costs while achieving environmental adaptability.

AI summary
A ventilation fan includes a body unit, which has a fan disposed in a body case and a fan controller operable to control an air volume of the fan. The ventilation fan also includes a sensor module having an indoor environment detecting sensor and a module controller operable to control a detecting operation of the indoor environment detecting sensor. The body unit has a module mount on which the sensor module is mounted and another sensor module can be mounted in place of the sensor module. The module mount is connected to the fan controller. The module controller outputs detection information obtained based on a detection result of the indoor environment detecting sensor to the fan controller, which in turn controls the air volume of the fan based on the detection information inputted thereto.
