Nipple Shield Gecko-Adhesion Microstructures and SNS Conduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nipple shields slip due to poor surface attachment, and supplementary nursing systems (SNS) are not compatible with them, leading to inefficient fluid flow and discomfort during breastfeeding.
Innovation Solution
A nipple shield with micro-structures featuring angled fibers for secure adhesion and an integrated SNS conduction system with microtubes and adjustable flow valves, allowing for secure attachment and adjustable fluid flow independent of gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional nipple shields are used, then they provide a large and firm target for latching and protection of the nipple, but they have poor surface attachment and slip down or fall off the woman's breast
Solution Approach 1:
The nipple shield incorporates gecko-inspired microstructures with porous or textured surface features that increase surface area and enable reversible adhesion to the breast, preventing slipping while maintaining nipple protection functionality
Solution Approach 2:
The patent replaces conventional mechanical attachment methods (adhesive tapes, elastic bands, or rigid fixation) with gecko-inspired dry adhesion mechanisms that use van der Waals forces through microstructured surfaces, enabling secure yet reversible attachment without additional mechanical components
2Strength
If conventional nipple shields are used, then they provide nipple protection, but they are not compatible with Supplementary Nursing System (SNS)
Solution Approach 1:
The nipple shield is designed with dual functionality: it maintains its primary role as a protective barrier while incorporating integrated SNS ports and fluid conduction pathways that enable compatibility with supplementary nursing systems, allowing one device to serve multiple purposes
3Quantity of substance
If conventional SNS are used, then they provide supplementary nutrition through a tube taped to the nipple, but the fluid flow is not adjustable to the baby's suction motion and leads to significant fluid spillage
Solution Approach 1:
The SNS system incorporates flow sensors or pressure-sensitive mechanisms that detect the infant's suction intensity and automatically adjust fluid delivery rate, creating a closed-loop feedback system that matches nutrition flow to the baby's actual consumption needs and prevents spillage
Solution Approach 2:
The patent replaces static, gravity-dependent fluid delivery with dynamic flow control mechanisms that can actively adjust delivery rate in real-time based on infant suction motion, using pumps, valves, or pressure-regulating elements responsive to flow demand
