Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric nasal aspirators face issues with nasal fluid entering the host through the outlet tube, causing pollution and making cleaning inconvenient due to the design of the suction bin assembly.
Innovation Solution
A nasal aspirator suction bin assembly with an umbrella-shaped bracket and air holes that prevent nasal fluid from contacting the air holes during use, combined with a rotary fastening mechanism and sealing rings for easy assembly and cleaning, and a suction nozzle design that protects the nasal mucosa.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the outlet tube is directly connected to the host without a bracket structure, then the structure is simple, but nasal fluid enters the host through the outlet tube causing pollution
Solution Approach 1:
The outlet tube is divided into multiple sections: the first outlet tube connected to the host, and the second outlet tube extending into the cavity. The bracket structure separates the air hole (for airflow) from the liquid collection area, creating distinct functional zones that prevent fluid contamination while maintaining structural organization.
Solution Approach 2:
The bracket acts as an intermediary structure between the outlet tube and the host. It includes a baffle that intercepts nasal fluid before it can reach the air hole, allowing air to pass through while blocking liquid. This intermediary element solves the contradiction by mediating between the need for simple connection and the need for fluid protection.
2Ease of operation
If the suction bin assembly is designed with easy disassembly for cleaning, then cleaning convenience is improved, but sealing performance may deteriorate
Solution Approach 1:
The outlet tube is nested within the bracket structure, with the bracket tube receiving the outlet tube. This nested arrangement allows the components to be easily assembled and disassembled for cleaning, while the nested fit maintains reliable sealing when connected. The first outlet tube fits into the bracket tube, creating a secure yet separable connection.
Solution Approach 2:
A sealing ring is introduced at the connection between the first outlet tube and the bracket tube. This flexible sealing element ensures reliable sealing performance while allowing the components to be easily disassembled for cleaning. The sealing ring compensates for minor dimensional variations and maintains the seal during repeated assembly and disassembly operations.
3Reliability
If the bracket extends deeply into the cavity to block fluid, then fluid protection is improved, but the suction tube and outlet tube communication may be blocked
Solution Approach 1:
The bracket is designed with spatially differentiated functions: the baffle extends into the cavity to block fluid at critical locations, while the bracket tube with air holes maintains airflow pathways. The blocking action is localized to where fluid would otherwise reach the outlet, while air communication is preserved through strategically positioned holes in the bracket tube. This local differentiation resolves the contradiction between blocking effectiveness and airflow maintenance.

Function Achieved in This Case
The design effectively prevents nasal fluid from entering the host, ensuring cleanliness, facilitates easy disassembly and cleaning, and provides strong sealing and comfort while protecting the nasal mucosa.
Implementation Method 1
a micro-vacuum pump compresses and stretches the air in the pump cavity with a fixed volume to form vacuum, forming a pressure difference, sucking nasal fluid into the cavity from the suction tube
Implementation Method 2
a micro-vacuum pump compresses and stretches the air in the pump cavity with a fixed volume to form vacuum, forming a pressure difference, sucking nasal fluid into the cavity from the suction tube

AI summary
A nasal aspirator suction bin assembly comprises a suction bin base, which has a first connecting end connected with a host and a second connecting end connected with a suction bin cover; after the suction bin base is connected with the suction bin cover, a cavity is formed therein; the middle of the suction bin base is provided with an outlet tube, which runs through the suction bin base and extends into the cavity; the upper end of the suction bin cover is provided with a suction tube, which runs through the suction bin cover and extends into the cavity; a bracket is arranged in the cavity, and the bracket comprises a bracket tube which can be inserted on the outlet tube and a baffle arranged at the other free end of the bracket tube, and at least one air hole is arranged on the bracket tube to keep the suction tube and the outlet tube in communication all the time; the cavity is used to store the inhaled nasal fluid. Because of the umbrella-shaped bracket, the nasal fluid cannot touch the position of the air hole during normal use and small-angle inclined use, so the nasal fluid cannot enter the host and cause pollution.
