Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eye washing devices are inadequate for effectively flushing eyes in remote locations where access to a fluid source and a convenient method for directing fluid to the eyes is limited.
Innovation Solution
A portable eye washing device comprising a hollow spike for piercing a fluid source, a feed tube, a fitting with dual outputs, a distribution tube forming a closed loop for wearing around the head, and cannula outlets aligned with the eyes to direct fluid for flushing, allowing for efficient eye irrigation from any fluid source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a portable eye washing device is designed with a closed loop distribution tube and cannula outlets, then the ease of operation and portability are improved, but the device complexity increases
Solution Approach 1:
The device is divided into distinct functional segments: a spike for piercing fluid sources, a feed tube for fluid transport, a fitting with dual outputs, a closed loop distribution tube forming a headband, and cannula outlets for eye irrigation. Each segment performs a specific function and can be independently optimized, while the modular assembly provides ease of operation despite the multiple components involved.
2Adaptability or versatility
If the distribution tube forms a closed loop for wearing around the head, then the adaptability and portability are improved, but the device complexity increases
Solution Approach 1:
The closed loop distribution tube serves multiple functions: it acts as a headband for wearing comfort, provides structural support for positioning cannula outlets, and enables portable use in remote locations. The device can be adapted to different users and fluid sources, enhancing versatility while the integrated design manages the complexity through functional consolidation.
3Reliability
If the cannula outlets are aligned with the user's eyes, then the effectiveness of eye flushing is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The cannula outlets are positioned and oriented to provide localized fluid delivery precisely at the eye level. The alignment is optimized for the specific function of eye flushing, with the cannula outlets angled to direct fluid into the eyes. This localized optimization ensures effectiveness while the overall device structure accommodates manufacturing tolerances through design flexibility in the distribution tube configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables effective flushing of eyes in remote locations by allowing fluid to be easily directed into the eyes from any available fluid source, ensuring quick and efficient removal of chemicals or foreign substances.
Implementation Method 1
a spike that can pierce a fluid source and the spike is hollow to pass fluid therethrough
Implementation Method 2
The cannula has a pair of outlets to pass the fluid therethrough. Each of the outlets is aligned with a respective one of the user's eyes when the distribution tube is worn around the user's head. Thus, each of outlets directs the fluid into the user's eyes for flushing the user's eyes.
Data Source
AI summary
A portable eye washing station includes a spike that can pierce a fluid source and the spike is hollow to pass fluid therethrough. A feed tube is fluidly coupled to the spike to receive the fluid from the spike. A fitting is fluidly coupled to the second end of the feed tube and the fitting has a pair of outputs to pass the fluid therethrough. A distribution tube is fluidly coupled to each of the outputs on the fitting such that the distribution tube forms a closed loop for wearing around a user's head. A cannula is fluidly coupled to the distribution tube to release the fluid and the cannula has a pair of outlets. Each of the outlets is aligned with a respective one of the user's eyes when the distribution tube is worn around the user's head. Thus, each of the outlets directs the fluid into the user's eyes for flushing the user's eyes.
