Biofluid Collection Lid Assembly With Ergonomic Sealing Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sample collection containers and lids are ergonomically inadequate, leading to contamination and inefficiency in collecting biological samples due to mismatched angles and rough edges, causing discomfort and spillage.
Innovation Solution
A sample collection container system with a sealing member and lid assembly that forms a seal against the body part during biofluid collection, ensuring ergonomic fit and preventing spillage by aligning with the natural trajectory of the ejaculate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional sample collection containers are used, then the collection process is simple, but the sample may be contaminated and the collection is uncomfortable due to poor ergonomic design
Solution Approach 1:
The container incorporates a sealing member with specific local properties (flexible material, tapered shape) at the opening region to create an ergonomic seal around the body part, while the rest of the container maintains its simple cylindrical structure for easy handling and storage
2Reliability
If conventional containers without sealing members are used, then the device complexity is low, but spillage and contamination occur during collection and transport
Solution Approach 1:
The container is divided into functional segments: a rigid container body for structural integrity and a separate flexible sealing member for creating the seal. The sealing member can be attached to or integrated with the container body, allowing modular assembly that prevents spillage without overly complicating the overall structure
Solution Approach 2:
The sealing member is made of flexible material that can deform to conform to the body part geometry, creating an effective seal. This flexible component prevents spillage during collection and transport while adding minimal structural complexity to the container system
3Reliability
If the opening size is reduced to fit body parts, then the seal effectiveness improves, but the collection capacity may be limited
Solution Approach 1:
The sealing member has a tapered geometry with a narrower distal end for sealing around the body part and a wider proximal end that transitions to the full container opening. This allows the seal to be formed at the critical interface while the container body maintains sufficient volume for sample collection
Solution Approach 2:
The sealing member extends axially into the container body, creating a seal at multiple positions along the container length. This axial dimension allows effective sealing without requiring the entire container opening to be restricted, preserving collection capacity
