Eye Rinsing Element With Multi-Opening Soft Fluid Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye rinsing elements discharge rinsing fluid with a strong stream that can be uncomfortable and ineffective for users, particularly due to the importance of the distance from the eye to the element and the single opening design.
Innovation Solution
An eye rinsing element with two rinsing fluid discharge areas, each containing multiple openings, arranged on concentric circles, discharging fluid over a wider area with softer beams, allowing parallel fluid streams for enhanced comfort and effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single opening is used for discharging rinsing fluid, then the device structure is simple, but the stream is strong and the distance from the eye to the element is crucial
Solution Approach 1:
The single opening is divided into multiple openings (at least 6, preferably at least 8, most preferred at least 10) arranged on concentric circles. Each opening has a diameter between 0.1 mm and 5 mm, preferably between 0.5 mm and 1.5 mm. This segmentation distributes the fluid discharge across multiple points, creating softer individual streams while maintaining adequate rinsing coverage.
Solution Approach 2:
The openings are arranged on two concentric circles (inner and outer circles) centered around a central point of the discharge area. The outer circle comprises more openings than the inner circle, with neighboring openings having specific angular distances (90° for inner circle, 45° for outer circle). This two-dimensional circular arrangement distributes the fluid discharge over a wider area, creating broader and softer beams with diameters of at least 1 mm, more preferred more than 1.1 mm, most preferred more than 1.2 mm.
2Ease of operation
If multiple openings are used for discharging rinsing fluid, then the beam becomes broader and softer, but the device complexity increases
Solution Approach 1:
Multiple openings are combined within a single discharge area that covers an area of at least 1 cm2, more preferred at least 2 cm2, most preferred at least 3 cm2. The openings are integrated into a unified structure with concentric circular patterns, merging the complexity of multiple openings into a standardized, manufacturable design that maintains structural simplicity while achieving the desired fluid distribution.

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 design provides a more comfortable and effective rinsing process by distributing fluid over a broader area with softer streams, improving user experience and safety.
Implementation Method 1
rinsing fluid is discharged over a wider area than typically known from the prior art and exits the element softer compared to typical eye rinsing elements with just one opening
