Vehicle Perfume Apparatus Single Shaft Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle perfume generation systems are complex and lack effective sealing, making it difficult to control the airflow and perfume distribution efficiently, leading to potential contamination from external pollutants and bacterial growth.
Innovation Solution
A simplified apparatus using a single rotating shaft to control airflow through both perfume generating parts, with a door seating member and sealing members to enhance sealing, and a cartridge design for easy perfume replacement, reducing pressure drop and improving air volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple control valves are used to control perfume supply in each passage, then perfume distribution can be controlled, but the device complexity increases and control becomes difficult
Solution Approach 1:
The patent combines multiple control valves into a single control valve that regulates airflow to multiple perfume generating passages. This merging of control elements simplifies the device configuration while maintaining the ability to control perfume distribution across different passages, directly resolving the contradiction between ease of operation and device complexity
Solution Approach 2:
The single control valve is designed to perform multiple functions by controlling airflow to several perfume generating passages simultaneously. This multi-functional design allows one component to replace what would traditionally require multiple separate control valves, reducing overall system complexity while preserving control capabilities
2Temperature
If external air is introduced through the air conditioner, then cooling and heating functions are provided, but harmful substances and bacterial foreign materials are delivered to the vehicle interior
Solution Approach 1:
The patent introduces perfume as an intermediary substance that is mixed with the air flowing through the air conditioner. This perfume-laden air serves as a mediator that not only provides temperature control but also creates a scented atmosphere that can mask or counteract harmful odors and bacterial contaminants, thereby addressing the contamination issue while maintaining air conditioning functionality
Solution Approach 2:
The patent converts the potentially harmful effect of circulating air that may carry contaminants into a beneficial effect by introducing perfume that improves air quality perception. The perfume acts as a beneficial agent that transforms the air stream from a potential vector of contamination into a medium that enhances interior air quality and passenger comfort
3Device complexity
If a single rotating shaft controls airflow through both perfume generating parts, then device complexity is reduced, but sealing ability must be maintained to stably control perfume
Solution Approach 1:
The patent employs flexible sealing members (such as rubber or elastomeric materials) that can deform to maintain tight seals around the rotating shaft and its components. These flexible sealing elements accommodate the rotation and movement of the shaft while preventing perfume leakage, thereby maintaining reliable sealing in the simplified single-shaft configuration
Solution Approach 2:
The patent applies sealing members specifically at critical locations where the rotating shaft interacts with stationary components and where perfume passages are accessed. This localized application of sealing elements ensures that reliability is maintained at key interfaces without requiring complex sealing systems throughout the entire device, thus resolving the contradiction between simplicity and reliability
