Baby Bib With Crescent Silicone Collar and Snap Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baby bibs either cause discomfort and strangulation sensation due to neck ties or are uncomfortable and provide poor protection due to rigid plastic materials without ties.
Innovation Solution
A baby bib design featuring a flexible fabric screen with a crescent-shaped silicone collar and adjustable tabs or sleeves that ensure a secure fit without encircling the neck, providing comfort and protection from regurgitation leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tie is used to secure the bib around the baby's neck, then the bib provides adequate protection, but the baby feels constricted and discomfort increases
Solution Approach 1:
The patent removes the traditional neck tie entirely and replaces it with a snap fastener system positioned at the back of the neck. This extracts the harmful constriction element while preserving the securing function through the snap mechanism that fastens the two tabs together without encircling the neck.
Solution Approach 2:
The patent introduces snap fasteners as an intermediary mechanism between the tabs. Instead of using a continuous tie that constricts the neck, the snap fastener provides a discrete, localized fastening point that secures the bib without creating the harmful encirclement effect.
2Reliability
If the tie is tightened to ensure adequate protection, then the seal improves, but the constriction and discomfort increase
Solution Approach 1:
The patent extracts the problematic tight encirclement mechanism and replaces it with a localized snap fastening system. The seal is achieved through the collar and fabric design rather than through tight neck encirclement, allowing adequate protection without the harmful constriction sensation.
3Ease of operation
If rigid plastic material is used to create tabs without ties, then the bib secures without neck encirclement, but comfort decreases and protection is poor
Solution Approach 1:
The patent employs a composite construction combining a rigid plastic collar with soft fabric material. The rigid collar provides structural support and secure attachment at the neck, while the soft fabric portions ensure comfort and effective protection against spills, resolving the contradiction between neck freedom and protection quality.
Solution Approach 2:
The patent applies different material properties to different parts of the bib: the collar area uses rigid plastic for secure attachment and structural support, while the main body and tabs use soft fabric for comfort and protection. This local differentiation of material quality allows the bib to simultaneously achieve secure fastening without ties and effective protection.
4Device complexity
If tabs are made rigid to secure the bib without fastening, then the complexity is reduced, but the comfort and protection deteriorate
Solution Approach 1:
The patent uses composite materials where the rigid plastic collar provides the necessary structural support for secure attachment, eliminating the need for complex fastening mechanisms, while the soft fabric portions maintain comfort. This material composition allows simple construction without sacrificing comfort or protection.
