Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nasal rinse products are bulky and not portable, making them difficult to carry around, and existing solutions do not effectively accommodate different nostril sizes or provide gentle pressure for nasal irrigation.
Innovation Solution
A portable ampoule with a specialized tip and sealer that includes a tapered surface to fit various nostril sizes and a sealing device that permanently unseals upon decoupling, allowing for gentle pressure dispensing of cleansing solution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional nasal rinse products are used, then nasal irrigation function is provided, but portability is poor and they are bulky
Solution Approach 1:
The device is divided into distinct functional components: a compact body for fluid storage, a specialized tip for nasal insertion, and a sealing device for controlled dispensing. This segmentation allows each component to be optimized for its specific function while maintaining overall portability.
Solution Approach 2:
The sealing device is nested within the tip assembly, and the tip is inserted into the body structure. This nested configuration minimizes the overall volume of the device when not in use, making it portable and easy to carry in personal items.
2Ease of manufacture
If a standardized tip is used, then manufacturing is simplified, but adaptability to different nostril sizes is poor
Solution Approach 1:
The tip features a tapered surface with varying diameter along its length, creating different local zones: a wider base portion for comfort and a narrower apex for insertion. This local variation in geometry allows the tip to adapt to different nostril sizes while maintaining a simple manufacturing process using standard tapering techniques.
3Productivity
If high pressure is used for fluid dispensing, then cleansing effectiveness is improved, but user comfort decreases due to harsh spray
Solution Approach 1:
The tip incorporates a tapered surface that creates a pressure gradient along the fluid flow path. The gradual tapering from base to apex allows pressure to build progressively, delivering effective cleansing at the target area while maintaining gentler pressure during insertion and along the passage, thus avoiding user discomfort.
Solution Approach 2:
The tapered surface of the tip uses curved geometry to smoothly guide and attenuate the fluid flow. This curvature helps distribute the fluid pressure evenly and prevents jet streaming or spraying effects, delivering cleansing solution in a controlled, comfortable manner.
4Ease of operation
If the aperture remains open, then fluid dispensing is simple, but accidental leakage during storage occurs
Solution Approach 1:
The sealing device is pre-positioned to automatically seal the aperture when not in use. This preliminary sealing action prevents accidental leakage during storage and transport, while allowing rapid opening when needed for dispensing, thus maintaining both reliability and ease of operation.
Solution Approach 2:
The sealing device acts as an intermediary element between the stored fluid and the external environment. It provides a reliable seal when closed and allows controlled access when opened, mediating between the need for leak prevention and simple fluid dispensing operations.

AI summary
The present disclosure relates to a portable ampoule with a specialized tip and sealer. In a general aspect, the portable ampoule for dispensing fluid may include a body configured to contain cleansing solution. A neck may be coupled to the body and configured to control the flow of the solution. A tip may be coupled to the neck and have an aperture for solution release. A sealing device may be coupled to the tip and configured to seal the aperture. The sealing device may permanently unseal the aperture upon decoupling from the tip.
