Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pacifiers often fail to provide a hygienic and easy-to-store solution, as they do not effectively prevent saliva accumulation and can be cumbersome for children with limited movement due to their design.
Innovation Solution
A hygienic pacifier design featuring a toroidal shield that automatically retracts into a spherical storage position using a unitary, medical-grade silicone structure, eliminating the need for external forces and incorporating a concave face plate with slits for saliva exit and an ergonomic shape for easy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional pacifier design is used, then the structure is simple, but saliva accumulation occurs and hygiene is compromised
Solution Approach 1:
The pacifier is divided into functionally distinct segments: a toroidal shield portion and a nipple portion. The shield portion can be separated from the nipple portion, allowing the shield to be inverted for cleaning while the nipple remains attached. This segmentation enables targeted hygiene maintenance without requiring complete disassembly.
Solution Approach 2:
The shield portion is designed to be invertible, allowing it to be turned inside out for cleaning purposes. This inversion capability enables thorough cleaning of the shield's interior surface by exposing it to the exterior, directly addressing the saliva accumulation problem while maintaining a relatively simple overall structure.
2Ease of operation
If conventional pacifier design is used, then manufacturing is simple, but storage is cumbersome for children with limited movement
Solution Approach 1:
The shield portion is designed to nest within or around the nipple portion when retracted, creating a compact storage configuration. The toroidal shape of the shield allows it to collapse or fold into a smaller volume that can be easily held by children with limited movement capabilities, while the unitary construction maintains manufacturing simplicity.
Solution Approach 2:
The shield portion is made dynamically configurable, transitioning between an extended functional position during use and a retracted compact position for storage. This dynamic capability is achieved through the elastic properties of the unitary silicone construction, allowing the shield to automatically retract without requiring additional mechanical components.
3Ease of operation
If the shield is made retractable for compact storage, then storage ease improves, but the mechanism becomes more complex
Solution Approach 1:
The shield portion automatically retracts using its own elastic properties without requiring external forces or additional mechanical mechanisms. The unitary silicone construction provides inherent elasticity that enables the shield to return to its compact form after being extended, eliminating the need for springs, motors, or other complex retraction mechanisms.
Solution Approach 2:
The physical parameters of the shield portion, specifically its elasticity and flexibility, are optimized to enable automatic retraction. By adjusting the material properties and geometric configuration of the unitary silicone construction, the shield achieves the desired retractability without adding mechanical complexity.

AI summary
A hygienic pacifier is set forth. The pacifier includes a base section having a nipple extending therefrom. The base section has a cross-sectional thickness. A substantially spherical recoil shield section is integrally formed with the base section. The shield section forms a wall having a cross-sectional thickness that is thinner in cross section than the cross-sectional thickness of the base section. The wall has recoil properties due to the spherical geometry of the shied section. The wall forms a shield around the nipple when recoiled.
