Applicator Compression Segment Viscosity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing applicator devices face challenges in delivering liquids across a range of viscosities, particularly for body applications like the vaginal area, where low viscosity liquids can leak and high viscosity liquids require excessive force, and there is a need for a compact, easy-to-use design.
Innovation Solution
The development of an applicator with a housing featuring a substantially continuous wall with varying dimensions and segments, including a compression segment for ease of product delivery, a removable twist-off closure, and raised texturing for improved grip, capable of handling liquids with viscosities from 100 cP to 300,000 cP without requiring excessive force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the applicator delivers low viscosity liquids, then the liquid flows easily through the applicator, but the liquid may be over-applied or leaked during application
Solution Approach 1:
The patent modifies the physical parameters of the applicator by incorporating a compression segment with reduced wall thickness and increased flexibility. This parameter change allows the applicator to compress and control the flow of low viscosity liquids, preventing over-application and leakage while maintaining ease of delivery.
Solution Approach 2:
The compression segment introduces a dynamic element to the applicator structure. By making this segment flexible and compressible, the applicator can adapt its internal volume and pressure in real-time during use, enabling precise control over liquid delivery and preventing unwanted flow or leakage.
2Reliability
If the applicator delivers high viscosity liquids, then the liquid can be contained effectively, but excessive force is required to expel the liquid from the applicator
Solution Approach 1:
The patent changes the structural parameters of the applicator by creating a compression segment with thinner walls and different material properties. This allows the segment to compress more easily under manual pressure, reducing the force needed to expel high viscosity liquids while maintaining effective containment during storage and transport.
Solution Approach 2:
The applicator is divided into distinct functional segments: a base segment for containment, a compression segment for force application, and a delivery segment for product ejection. This segmentation allows each part to be optimized independently - the compression segment requires less force to compress while the delivery segment maintains containment effectiveness.
3Volume of moving object
If the applicator is made small and discrete, then it is easier to carry and store, but it becomes difficult to grasp and manipulate for product delivery
Solution Approach 1:
The patent applies local quality by adding raised texturing to specific portions of the applicator exterior. This creates localized grip-enhancing features that improve grasping and manipulation without increasing the overall volume of the applicator, maintaining its compact and portable nature.

AI summary
The present disclosure provides applicators adapted to or configured to deliver a product therefrom. The applicators can be particularly designed for delivery to certain body parts of the human body, such as to the vaginal area. The applicator can comprise a housing formed of a substantially continuous wall extending along a longitudinal housing axis between a base end and an application end, the substantially continuous wall defining: a base segment extending from the base end toward the applicator end; a delivery segment extending from the applicator end toward the base end; and a compression segment interconnecting the base segment and the delivery segment. The housing can define a substantially hollow interior configured for retaining a product for delivery through the delivery segment.
