Ventilation system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation systems in building structures often lack sufficient wiring to support the integration of additional functions beyond ventilation and lighting, requiring extensive re-wiring to operate multiple devices individually, which is inefficient and undesirable.
Innovation Solution
A ventilation system with a control module that includes a wireless communication system and a wall switch allowing for the integration of an auxiliary device, such as a humidity monitor, which can be powered continuously and controlled via wireless signals, along with an expansion connector for additional modules, enabling individual control of the blower, light, and auxiliary devices using a single wall switch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing ventilation systems are used with standard wiring, then the system structure remains simple, but the system cannot support additional functions beyond ventilation and lighting
Solution Approach 1:
The control module serves as a universal platform that can accommodate multiple different auxiliary devices (humidifier, air purifier, heater, etc.) through a standardized interface. This allows the ventilation system to perform multiple functions without requiring separate control systems or complex wiring for each device, resolving the contradiction between functional versatility and wiring simplicity.
Solution Approach 2:
The control module acts as an intermediary device that bridges the gap between the existing simple wiring infrastructure and the desired multiple functions. It receives power through the existing single wire and provides wireless control capabilities, enabling auxiliary devices to be integrated without modifying the building's wiring system.
2Adaptability or versatility
If auxiliary devices are integrated into the ventilation system, then system functionality is enhanced, but extensive re-wiring is required
Solution Approach 1:
The system replaces the traditional mechanical/electrical control approach (physical wiring and switches) with wireless communication technology. The control module and auxiliary devices communicate via wireless signals, eliminating the need for extensive re-wiring while still enabling individual control of multiple functions. This substitution resolves the contradiction between functional integration and installation ease.
3Ease of operation
If individual control of multiple devices is implemented, then user convenience is improved, but the control system becomes more complex
Solution Approach 1:
The control module provides self-service functionality by automatically managing the control of multiple auxiliary devices through a unified wireless interface. Users can control all functions through a single remote or interface without needing to understand or manage complex control systems, while the control module handles the complexity of coordinating multiple devices internally.

AI summary
A ventilation system having a blower, a light and an auxiliary device configured to perform a function in the room other than ventilation and lighting. A control module is operatively connected to the ventilation fan and has a light switch to activate the light and a blower switch to activate the blower. A communication system including an antenna receives wireless signals and a processor operates the light switch and the blower switch based on the wireless signals. A wall switch has a plurality of device operators to provide one or more inputs to the control module.
