Hinged Splash Guard Enclosure for Syringe Leakage Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Syringe assemblies in wet lab settings are prone to failure due to built-up pressure, leading to hazardous liquid leakage or aerosolization, posing a safety risk.
Innovation Solution
A splash guard comprising two enclosure halves with a hinge mechanism that forms a sealed cavity around the syringe assembly, containing any liquid leakage and preventing splashing, featuring a handle for easy engagement and disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a syringe assembly is used for filtration, then filtration function is achieved, but pressure buildup causes filter disassembly and liquid splashing
Solution Approach 1:
The splash guard acts as an intermediary protective barrier between the syringe assembly and the external environment. It contains the filter and syringe within an enclosed cavity, preventing liquid from escaping during pressure buildup or filter disassembly events.
Solution Approach 2:
The splash guard provides beforehand protection by pre-establishing an enclosed protective environment around the syringe assembly. The enclosure is designed to withstand pressure buildup and contain any potential liquid ejection before it can cause harm to the user or surroundings.
2Object-affected harmful factors
If an enclosed cavity is formed to contain liquid leakage, then safety is improved, but device complexity increases
Solution Approach 1:
The splash guard is segmented into two separate enclosure halves that can be independently manufactured and then assembled. This segmentation simplifies the manufacturing process and allows for easier cleaning and maintenance while still providing complete enclosure when assembled.
Solution Approach 2:
The enclosure halves utilize thin-walled structures that provide adequate containment while minimizing material usage and overall complexity. The thin film approach allows the enclosure to be lightweight yet sufficiently strong to contain liquid under pressure.
3Ease of operation
If the enclosure halves are pivotably coupled with a hinge, then ease of operation is improved, but manufacturing complexity increases
Solution Approach 1:
The hinge mechanism is designed to be self-contained within the enclosure halves, requiring no additional external components or complex assembly procedures. The hinge allows the halves to pivot and lock together automatically, providing ease of operation without significantly increasing manufacturing complexity.

AI summary
A splash guard engages to a syringe assembly to mitigate splashing of liquid in instances of failure of the syringe assembly. The splash guard forms an enclosure around the syringe assembly, such that, in the event of failure, the liquid or an aerosol form of the liquid is contained within the enclosure. The splash guard may include a handle for engaging and disengaging the splash guard from the syringe assembly. As a user applies an actuation force on the handle, the splash guard opens into an opened state. In the opened state, the user can position the splash guard around the syringe assembly before releasing the handle and returning to the splash guard to a closed state.
