Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The collection, transport, and analysis of semen samples are cumbersome, time-consuming, and prone to errors due to the need for multiple steps and handling by both the subject and the technician.
Innovation Solution
A sample device and kit that allows for the collection, transport, and analysis of semen samples in a single, pre-packaged unit, featuring a body with open ends, caps for sealing, and a plug for sealing openings, enabling easy extraction and analysis without the need to transfer the sample.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a semen sample is collected in a sample cup with a lid that must be unscrewed for extraction, then the sample can be collected and transported, but the process becomes time-consuming and requires numerous steps involving multiple handling operations
Solution Approach 1:
The invention combines the collection cup, extraction opening, and sealing mechanism into a single integrated cap structure. The cap simultaneously serves as the collection container closure and provides a built-in opening for direct pipette access, eliminating the need to unscrew the lid and transfer the sample to a separate container.
Solution Approach 2:
The cap is segmented into functional zones: a sealing portion that interfaces with the cup, a body portion containing the opening, and an optional plug component. This segmentation allows each element to perform its specific function while working together as an integrated system that reduces handling steps.
2Ease of operation
If the sample is transferred from the collection cup to a slide for analysis, then the analysis can be performed, but the process becomes prone to errors and requires numerous handling steps
Solution Approach 1:
The cap's opening is positioned and sized to allow the pipette to be inserted directly through the cap structure itself, enabling the technician to extract the sample without removing the cap or transferring the sample to another container. The system serves itself by providing direct access through the closure component.
3Reliability
If a plug is added to seal the opening in the cap, then the sample remains secure during transport, but the device complexity increases
Solution Approach 1:
The plug is designed as a simple, disposable component that can be easily inserted and removed. It provides effective sealing during transport but is intended for single use and can be discarded after the extraction is complete, avoiding the need for complex reusable sealing mechanisms.

AI summary
Devices, kits, and methods for samples, including devices, kits, and methods for the collection, transport, and/or testing of semen samples are described herein. A kit for a sample is provided, which includes a sample device having a body, a first cap configured to removably couple to the body at a first open end, and a second cap configured to removably couple to the body at a second open end. A cap can include an opening and a removable plug to seal the opening and/or a seal that receives a pipette and automatically seals when the pipette is removed. The kit can include a stand for holding one or more sample devices and/or a preservative suitable for preserving the sample at room temperature for between 1-120 hours or more.
