Ventilation and air conditioning system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ventilation-air conditioners have open air outlets that allow dust to enter when the ventilation component is not in use, leading to failures and reduced service life.
Innovation Solution
An automatic air-output device is integrated at the ventilation outlet, which opens or closes the outlet based on the ventilation component's operating state, using a sliding or cylindrical mechanism driven by a power source to regulate airflow and prevent dust ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the ventilation outlet is kept open for air output, then air ventilation function is improved, but dust enters the ventilation component causing failures
Solution Approach 1:
The patent applies the dynamics principle by implementing an automatic air-output device that can dynamically change its state between open and closed positions. The device is driven by a driving mechanism that responds to the operating state of the ventilation component, allowing the outlet to be open during operation for air output and closed during non-operation to prevent dust ingress, thus resolving the contradiction between ventilation function and component reliability
2Reliability
If a baffle is used to close the ventilation outlet, then dust ingress is prevented, but the outlet cannot be fully closed when the ventilation component is not working
Solution Approach 1:
The patent applies segmentation by dividing the outlet closure function into two parts: a baffle that provides partial closure and dust protection, and an automatic air-output device that provides complete closure when needed. This segmented approach allows the baffle to protect against dust while the automated device ensures full closure during non-operation periods
3Productivity
If the automatic air-output device protrudes from the housing, then the outlet is opened for air output, but the outer surface becomes non-planar
Solution Approach 1:
The automatic air-output device is designed to be dynamic, protruding from the housing outer surface only when air output is required and retracting to be flush with the surface when not in use. This dynamic positioning resolves the contradiction between maintaining air output capability and preserving the aesthetic planar appearance of the housing exterior

AI summary
The present disclosure provides a ventilation and air conditioning system. The ventilation and air conditioning system can include a ventilation and air conditioning body including a ventilation component and an automatic air-output device arranged at a ventilation outlet of the ventilation and air conditioning body and configured to open or close the ventilation outlet according to an operating state of the ventilation component. The automatic air-output device is coupled to a power switch of the ventilation component. When the ventilation component is powered on, the automatic air-output device opens the ventilation outlet of the ventilation component to allow fresh air of the ventilation component to flow indoors. When the ventilation component is powered off, the automatic air-output device closes the ventilation outlet.
