Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing nasal cleaning devices often cause discomfort and choking due to excessive cleaning liquid in the nasal cavity, as they lack effective mechanisms for managing the flow and suction of cleaning solutions.
Innovation Solution
A nasal cleaner with a central control assembly that includes a water supply module and a negative pressure generator module, featuring a water pump for pressurized liquid delivery and a vacuum pump for suction, ensuring smooth flow and preventing choking by balancing pressure within the nasal cavity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large amount of cleaning liquid is filled into the nasal cavity, then the nasal cleaning effect is improved, but discomfort and choking occur in the patient
Solution Approach 1:
The patent applies pneumatic and hydraulic principles by using a vacuum pump to create negative pressure for suctioning waste liquid and a water pump to create positive pressure for delivering cleaning liquid. This pressure-based fluid transmission system enables controlled flow of cleaning liquid while simultaneously removing waste, preventing choking while maintaining effective cleaning.
Solution Approach 2:
The patent implements discarding and recovering by separating the cleaning liquid flow path from the waste liquid flow path. The vacuum pump continuously suction s waste liquid from the nasal cavity into a collection container, while the water pump delivers fresh cleaning liquid. This continuous exchange ensures effective cleaning without overfilling the nasal cavity.
2Device complexity
If simple manual pressing is used to push water, then the device complexity is reduced, but the cleaning liquid cannot flow smoothly and choking may occur
Solution Approach 1:
The patent replaces the simple manual mechanical pressing system with an automated pump-based fluid transmission system. The water pump and vacuum pump automatically control the flow of cleaning liquid and waste liquid respectively, eliminating the need for manual operation while ensuring smooth, controlled flow that prevents choking.
Solution Approach 2:
The system performs self-service by automatically delivering cleaning liquid and suctioning waste liquid without requiring manual intervention. The water pump and vacuum pump operate autonomously to maintain proper fluid flow dynamics, ensuring smooth operation and preventing choking accidents.
3Ease of operation
If automatic water-filling and one-sided vacuum suction are used, then the ease of operation is improved, but the cleaning liquid may still cause discomfort in the nasal cavity
Solution Approach 1:
The patent merges the water supply function and negative pressure suction function into a coordinated system. The water pump delivers cleaning liquid while the vacuum pump simultaneously suction s waste liquid, creating a balanced flow that prevents overfilling the nasal cavity and causes discomfort, while maintaining automatic operation.
Solution Approach 2:
The patent changes the pressure parameters dynamically by using the vacuum pump to create negative pressure for suction and the water pump to create positive pressure for delivery. This coordinated pressure control ensures that cleaning liquid flows smoothly without causing discomfort or choking, while maintaining ease of automatic operation.
