Elastic Pacifier Shield Dual-State Impact Cover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pacifiers are cumbersome due to the need for separate shields and nipple covers, which can lead to dirt and bacterial contamination when dropped, requiring frequent cleaning and additional storage solutions.
Innovation Solution
A pacifier shield made of elastic material that transitions between two stable states upon impact, serving as both a protective shield and a nipple cover, reducing the number of components and eliminating the need for additional covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate nipple cover is added to protect the nipple from contamination, then the protection against dirt and bacteria is improved, but the device complexity increases
Solution Approach 1:
The patent combines the shield and nipple cover functions into a single integrated shield component. The shield is designed with a specific geometry that allows it to automatically cover the nipple when the pacifier is dropped, eliminating the need for a separate nipple cover while maintaining protection against contamination.
Solution Approach 2:
The shield serves multiple functions: it acts as a protective barrier preventing the nipple from being swallowed, and simultaneously functions as an automatic nipple cover when the pacifier is dropped. This multi-functionality reduces the overall number of components needed in the pacifier system.
2Ease of operation
If the shield is designed to automatically cover the nipple upon impact, then the ease of operation is improved, but the reliability of the shield's protective function may be compromised
Solution Approach 1:
The shield is designed as a dynamic component that can change its configuration between two stable states: an open state during normal use that allows easy access to the nipple, and a closed state upon impact that automatically covers the nipple. The dynamic design allows the shield to adapt to different usage scenarios while maintaining both accessibility and protection functions.
Solution Approach 2:
The shield utilizes elastic material properties to enable automatic state transition upon impact. The elasticity allows the shield to deform during impact and then return to its original protective configuration, automatically covering the nipple without requiring manual intervention while maintaining the integrity of the protective function.
3Ease of manufacture
If the shield is made from elastic material to enable state transition, then the ease of manufacture is improved, but the strength of the shield may be reduced
Solution Approach 1:
The shield is made from elastic material that can undergo reversible deformation to enable automatic state transition between open and closed configurations. The elastic properties allow the shield to be manufactured as a single flexible element that can bend and fold without breaking, while still providing adequate structural strength for its protective functions.
Solution Approach 2:
The shield incorporates curved and folded geometric features that distribute mechanical stresses effectively. The specific geometry with folds and curves allows the elastic material to maintain structural integrity while enabling the automatic covering function, as the curved structures naturally redirect forces during impact and state transitions.

Function Achieved in This Case
The pacifier shield effectively prevents contamination and simplifies storage by automatically covering the nipple upon impact, reducing the need for separate covers and cleaning, while maintaining accessibility for the child.
Implementation Method 1
a pacifier comprises a nipple and a shield made of an elastic material, wherein the shield has two stable mechanical states
Implementation Method 2
upon impact to the shield, tension built up in the elastic material of shield transfers the shield from the first state to the second state
Implementation Method 3
The shield is shaped such that it transfers from the first, unfolded state to the second, folded state upon impact

AI summary
A pacifier (1) is provided which comprises a nipple (2) and a shield (3) made of an elastic material. The shield (3) comprises two stable mechanical states: one in which the shield (3) acts as a shield and another in which the shield (3) acts as a nipple cover. The shield (3) is transformable from one stable mechanical state to another upon an impact to the shield (3).
