Solution Overview

Problem

Conventional syringes used for artificial insemination often lack tactile feedback and comfort due to sharp edges and pointed ends, which can make the process less effective and more uncomfortable for users.

Innovation Solution

A syringe design featuring a substantially cylindrical body with a rounded nub extending from the distal end, providing tactile feedback and a smooth, comfortable experience by allowing the user to feel the cervix during insertion and featuring openings with irregular shapes to diffuse the fluid effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional syringes are used for artificial insemination, then the device structure is simple and easy to manufacture, but the user comfort and tactile feedback are poor due to sharp edges and pointed ends

Engineering Contradiction:
Improveuser comfortVSAvoidmanufacturing complexity
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The syringe is designed with a rounded nub at the distal end instead of a sharp point, and rounded edges along the body, eliminating sharp corners and points that cause discomfort during insertion and use

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Productivity

If conventional syringes with circular openings are used, then the manufacturing process is simple, but the fluid dispersion effectiveness is reduced

Engineering Contradiction:
Improvefluid dispersion effectivenessVSAvoidopening shape complexity
Core Design Contradiction:
ProductivityVSEase of manufacture

Solution Approach 1:

The opening in the nub is designed with a non-circular shape (such as oval, elliptical, hourglass, or diamond) to optimize fluid dispersion patterns, creating different flow characteristics in different directions to improve effectiveness

Inventive Principle:
Principle #3Local quality

3Reliability

If a rounded nub design is implemented, then tactile feedback and user comfort are improved, but the device complexity increases

Engineering Contradiction:
Improvetactile feedbackVSAvoidstructural complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The nub is integrated as part of the syringe body structure rather than being a separate component, combining the tactile feedback function with the existing syringe structure to minimize overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An apparatus may include a plunger and a substantially cylindrical body. The substantially cylindrical body may include an end portion having rounded edges and may define a cavity sized to receive the plunger. The substantially cylindrical body may include at least one opening extending from the cavity to an external surface. The at least one opening may a substantially irregular shape. In some embodiments, the at least one opening may extend from the cavity through a nub to the external surface. The nub may have a rounded shape. In some embodiments, the substantially irregular shape may include one of a slit, an oval shape, an elliptical shape, an hourglass shape, a rectangular shape, and a diamond shape. In some embodiments, the opening may be part of a non-cylindrical fluid passage.
