Facial Basin Coupling Device for Sanitary Airflow Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing facial bathing technologies are complex, difficult to maintain, and often allow liquid to enter the exhaust port, making breathing and sanitation challenging.
Innovation Solution
A facial basin assembly with a flexible airflow conduit and a coupling device that directs airflow downward, preventing liquid from entering the exhaust pathway, while allowing users to move their head freely within the basin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex setup with electronic and mechanical components is used to facilitate facial submersion, then the facial bathing function is improved, but the device complexity and difficulty of maintenance increase
Solution Approach 1:
The device is divided into separate functional components: a removable coupling device with airflow pathway, a flexible airflow conduit, and a mouthpiece. This segmentation allows each component to be independently manufactured, maintained, and replaced, reducing overall system complexity while maintaining full facial bathing functionality
Solution Approach 2:
The airflow pathway is extracted from the basin structure and placed in a separate removable coupling device. This extraction eliminates the need for complex integrated electronic-mechanical systems within the basin, simplifying both the main basin structure and the airflow control mechanism
2Ease of operation
If the exhaust port is positioned at the bottom center of the basin to direct exhaust downward, then the exhaust function is improved, but the user must maintain deep face submersion reducing flexibility
Solution Approach 1:
The coupling device incorporates a flexible airflow conduit that can dynamically adjust its configuration as the user moves their head to different positions in the basin. This flexibility allows the exhaust port to remain at the bottom center for proper exhaust function while the user enjoys freedom of head movement without requiring deep submersion
3Ease of operation
If the exhaust port is directly connected to a mouthpiece at the bottom center, then the exhaust is directed properly, but liquid can easily enter the exhaust port compromising sanitation
Solution Approach 1:
The removable coupling device acts as an intermediary component between the basin and the mouthpiece. It includes a top surface that is not readily exposed to the environment, creating a protective barrier that prevents liquid from directly entering the airflow pathway while still allowing proper exhaust direction from the bottom center position
4Reliability
If the coupling device has a top surface not readily exposed to the environment, then liquid entry is prevented improving sanitation, but the device structure becomes more complex
Solution Approach 1:
The protective top surface is merged with the coupling device body as an integrated feature rather than a separate component. This design combines the protective function with the structural housing, preventing liquid entry while avoiding the need for additional separate protective elements that would increase complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables flexible head movement during facial bathing, simplifies maintenance and manufacturing, and maintains sanitary conditions by preventing liquid from entering the airflow pathway.
Implementation Method 1
the airflow conduit is flexible and elastic, enabling a user to position his/her face at different locations within the basin
Implementation Method 2
directing their breath downward through the top ledge of the basin towards the bottom of the basin

AI summary
A facial basin assembly includes a basin with a convex top side and a concave bottom side. The assembly features a mouthpiece to facilitate user breathing while their face is submerged in liquid. The mouthpiece is connected to a coupling device via one or more air flow conduits. This coupling device is designed to be removably inserted through a ledge of the basin and is adapted to direct the user's exhalation toward the bottom of the basin. The basin comprises a base portion and a curved portion, the latter allowing exhaled breath to escape into the environment.
