Pacifier Fitting System Using Facial Anthropometric Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pacifier sizing methods rely solely on age, neglecting variations in facial structure and palate size among children of the same age, leading to potential orthodontic and jaw alignment issues, and inadequate shield design affecting comfort and breathing.
Innovation Solution
A system using facial anthropometric data from images to calculate the size and shape of pacifier bulbs and shields, incorporating algorithms that consider age, weight, facial dimensions, and mandibular position for personalized fitting, enabling 3D printing for frequent adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If pacifier sizing is based solely on age, then manufacturing and inventory management are simplified, but fit accuracy and prevention of orthodontic problems deteriorate
Solution Approach 1:
The patent transitions from a single parameter (age) to multiple parameters (age, weight, facial measurements including mouth width, nose width, chin width, and cheekbone width) for pacifier sizing. This multi-parameter approach enables accurate customization of pacifier bulb size and shield dimensions to match individual infant facial structures, resolving the contradiction between manufacturing simplicity and fit accuracy.
2Ease of operation
If shield design focuses on comfort and aesthetic design, then appearance and user preference are improved, but fit and function issues such as lip support and mandibular movement deteriorate
Solution Approach 1:
The patent applies different design priorities to different regions of the shield. The shield is customized with varying dimensions at different locations based on specific facial measurements: the width and curvature are adjusted for lip support in the oral region, while the lateral extensions are optimized for mandibular movement space. This localized customization ensures both comfort/aesthetics and functional reliability simultaneously.
3Stability of the object's composition
If shield pressure is increased to secure fit, then attachment stability is improved, but mandibular forward movement and airway enhancement deteriorate
Solution Approach 1:
The patent employs asymmetric shield design where the pressure distribution is optimized rather than uniform. The shield contacts the face at specific points determined by facial geometry, providing sufficient attachment stability through strategic contact points while leaving the mandibular region with adequate clearance for forward movement. The asymmetric configuration ensures stability without harmful pressure on the jaw.
