Sperm Collection Device Airflow Control Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sperm collection devices often unintentionally change the stimulation intensity due to user error, leading to inconsistent ejaculation facilitation.
Innovation Solution
A sperm collection device featuring a core member made of elastic material with an insertion hole and an insertion space, accompanied by a container with a cylindrical base unit and a movable unit that adjusts airflow through an overlapping area, allowing for precise control of air flow rate via rotational adjustment, preventing unintended stimulation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the air amount adjustment ring is provided on the outer circumferential surface of the container, then the flow rate of air can be adjusted to control stimulation strength, but the ring-side opening may be unintentionally closed by user's fingers causing inconsistent stimulations
Solution Approach 1:
The patent introduces a cover member as an intermediary component between the user's fingers and the air amount adjustment ring. This cover member with a through-hole allows air to pass through while preventing fingers from blocking the ring-side opening, thus maintaining reliable and consistent air flow during device operation.
2Ease of manufacture
If the container structure is simplified, then ease of manufacture is improved, but the ability to precisely control air flow rate is reduced
Solution Approach 1:
The container is segmented into multiple functional components: a cylindrical container body, a separate air amount adjustment ring with rotational capability, and a cover member. This segmentation allows each component to be manufactured independently with standard processes while collectively achieving precise air flow control through the rotational positioning of the adjustment ring.
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
The device ensures consistent and intended stimulation levels by preventing airflow path closure and allowing precise adjustment of air flow rates, facilitating controlled ejaculation.
Implementation Method 1
a core member that is made of an elastic material and has an insertion hole for a penis and an insertion space in which the penis inserted in the insertion hole relatively moves inwardly and outwardly
Implementation Method 2
an airflow path is provided in an overlapping part in which the one end of the movable unit overlaps the other end of the base unit, and an adjustment mechanism that adjusts, based on a rotational angle of the movable unit with respect to the base unit, a flow rate of air flowing in and out of the container

AI summary
The sperm collection device includes a core member having an insertion hole for a penis and an insertion space, and a container having an internal space in which the core member is accommodated. The container includes a cylindrical base unit having a base end open in an axial direction of the base unit and attached to an insertion-hole-side end of the core member, and a cylindrical movable unit having a base end open in an axial direction of the movable unit and a front end being closed, and attached rotatably around an axis of the movable unit with respect to the other end of the base unit. In an overlapping part in which the base end of the movable unit overlaps the other end of the base unit, an airflow path and an adjustment mechanism are provided.
