Adjustable Saliva Suction Head Structure to Prevent Mucosa Wrapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing saliva suction tube structure causes discomfort and inconvenience due to its inability to adjust on the tube body, leading to suction force disappearance and accumulation of water/saliva in the oral cavity, resulting in choking and reduced practicality.
Innovation Solution
A saliva suction structure with an inner suction head, outer hood, and shrunk portion, featuring adjustable side holes and a spacing between the outer hood and shrunk portion, allowing quick angle adjustments to prevent buccal mucosa wrapping and suction force loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the suction head is fixed to the tube body with slits around the periphery, then the structure is simple and easy to manufacture, but the suction head cannot be rotated or adjusted, causing it to be securely sucked on the buccal mucosa and lose suction force
Solution Approach 1:
The suction head is divided into two separate parts: an inner suction head and an outer hood. The inner suction head can rotate independently within the outer hood, allowing adjustment of the suction angle while maintaining structural simplicity. This segmentation enables both ease of manufacture and operational flexibility.
Solution Approach 2:
The inner suction head is designed to be rotatable within the outer hood, transforming the static fixed structure into a dynamic adjustable one. This allows the suction head to adapt its angle during use, preventing it from being securely stuck on the buccal mucosa and maintaining continuous suction force.
2Device complexity
If the suction head cannot be adjusted, then the manufacturing cost is low and the structure is simple, but water and saliva accumulate in the oral cavity causing choking and discomfort
Solution Approach 1:
The rotatable inner suction head allows dynamic adjustment of the suction angle, enabling effective removal of water and saliva from the oral cavity. This prevents accumulation and choking while maintaining relatively simple device complexity through the straightforward rotation mechanism.
3Reliability
If the suction head is fixed on the tube body, then the structure is stable and reliable, but it cannot be adjusted quickly requiring repeated pulling and adjusting
Solution Approach 1:
The inner suction head can rotate within the outer hood to adjust the suction angle quickly and easily, while the overall structure remains stable and reliable. This dynamic adjustment capability eliminates the need for repeated pulling and adjusting, improving both operational convenience and suction force stability.
Solution Approach 2:
The inner suction head is nested within the outer hood, allowing it to rotate freely while maintaining a stable overall structure. This nesting design enables quick adjustment without compromising structural reliability.
4Force
If the suction head wraps around the buccal mucosa, then the initial suction force is strong, but the suction force disappears when the patient moves their mouth
Solution Approach 1:
The rotatable inner suction head allows the suction angle to adapt dynamically as the patient moves their mouth. This maintains continuous suction force by adjusting to the changing position, improving adaptability while preserving strong initial suction force.
