Solution Overview
Problem
Existing ventilation systems with integrated lighting require separate control systems for ventilation and lighting, leading to increased costs and limited functionalities, as well as independent operation of these components, which complicates usage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate control systems are used for ventilation and lighting, then independent control of each function is achieved, but device complexity and cost increase
Solution Approach 1:
The patent combines separate control systems for ventilation and lighting into a single integrated control unit. The controller receives user inputs and generates coordinated control signals for both the motor (ventilation) and lighting means, eliminating the need for separate control systems while maintaining independent functionality of each component.
Solution Approach 2:
The control unit is designed to perform multiple functions: it controls both the ventilation motor and the lighting means, manages different operating modes (night mode, daytime mode), and responds to various sensor inputs (presence detection, ambient light sensing). This universal controller replaces multiple specialized control systems.
2Ease of operation
If separate control systems are used for ventilation and lighting, then distinct management of each function is achieved, but manufacturing cost increases
Solution Approach 1:
The patent merges separate control systems into a single integrated control unit, reducing the number of components that need to be manufactured and assembled. This consolidation lowers manufacturing costs while maintaining the ability to distinctly manage ventilation and lighting functions through software control.
Solution Approach 2:
The universal controller is designed to handle multiple functions (ventilation control, lighting control, sensor processing) within a single device, reducing overall system cost compared to using multiple specialized control units.
3Adaptability or versatility
If ventilation and lighting operate independently with separate programs, then each function can be controlled separately, but ease of operation decreases due to multiple interactions required
Solution Approach 1:
The patent combines control of ventilation and lighting into a single integrated program. When a user activates a function (e.g., lighting), the controller automatically coordinates related functions (e.g., adjusting ventilation), reducing the number of separate interactions needed while maintaining adaptability through programmable modes.
Solution Approach 2:
The controller is programmed with pre-defined operating modes (night mode, daytime mode) that automatically coordinate multiple functions. When a mode is activated, the controller preliminarily determines the appropriate settings for both ventilation and lighting, reducing the need for multiple user interactions.
4Device complexity
If integrated control is implemented for ventilation and lighting, then device complexity is reduced, but functionality may be limited
Solution Approach 1:
The integrated control unit is designed with multi-functionality to compensate for the simplification of control scheme. It can control ventilation at different speeds, manage lighting intensity and timing, respond to sensor inputs, and implement various operating modes, thereby offering diverse functionalities within a single control system.
Solution Approach 2:
The controller implements dynamic control capabilities, allowing it to adapt its behavior based on sensor inputs (presence detection, ambient light levels) and user preferences. This dynamic responsiveness enables the simplified control system to provide versatile functionalities across different operating conditions.
