Biologic Response Teether with Composite Core for Jaw Development
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing teething devices fail to effectively accommodate varying bite forces and developmental stages of infants, potentially leading to improper jaw development and pain relief during teething.
Innovation Solution
A biologically designed teether that distorts in response to bite pressure, featuring a hard rigid polymer inner core and a compressible durometer material, allowing for adjustable bite force distribution and accommodating different developmental stages through varying thickness and surface angles, enabling directed pressure on the mouth surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a hard rigid polymer inner core is used, then structural strength and durability are improved, but comfort and pressure distribution worsen
Solution Approach 1:
The teether combines a hard rigid polymer inner core with a soft compressible outer layer, creating a composite structure that simultaneously provides structural strength and pressure distribution. The hard core maintains shape and durability while the soft outer layer conforms to the infant's gums and distributes bite forces evenly.
Solution Approach 2:
Different regions of the teether have different material properties - the inner core provides rigid structural support while the outer layer provides soft, compliant contact surfaces. This local differentiation of material quality allows the single device to satisfy both strength and comfort requirements.
2Ease of manufacture
If a single durometer material is used, then manufacturing simplicity is improved, but adaptability to different bite forces worsens
Solution Approach 1:
The teether uses composite materials with different durometer values - a harder inner core and a softer outer layer. This composite construction provides adaptability to varying bite forces while maintaining relatively simple manufacturing through co-molding or overmolding processes.
Solution Approach 2:
The invention changes the physical parameter of durometer hardness by using multiple materials with different hardness values in a single device, allowing adaptation to different bite forces without complicating the overall manufacturing approach.
3Manufacturing precision
If uniform thickness is used, then manufacturing precision is improved, but functional effectiveness worsens
Solution Approach 1:
The teether features variable thickness in its outer layer, with thicker regions providing cushioning for high-pressure areas and thinner regions allowing closer contact for low-pressure areas. This local variation in thickness optimizes pressure distribution across different parts of the infant's mouth.
Solution Approach 2:
The invention transitions from uniform thickness (one-dimensional consistency) to variable thickness (spatially distributed dimensional variation), adding functional complexity in the thickness dimension to improve pressure distribution while maintaining manufacturability.
4Object-affected harmful factors
If the teether is too soft, then comfort is improved, but structural stability worsens
Solution Approach 1:
The composite structure with a hard inner core and soft outer layer resolves the contradiction between comfort and stability - the soft outer layer provides comfort by conforming to gums and distributing pressure, while the hard inner core maintains structural stability and prevents deformation.
Solution Approach 2:
The soft outer layer acts as a flexible shell that provides comfort through conformability and pressure distribution, while the rigid inner core serves as the stable structural framework, combining the benefits of both flexible and rigid structures.

Function Achieved in This Case
The teether provides appropriate mechanical loads for proper jaw development, pain relief, and speech development by allowing infants to apply specific bite forces and angles, enhancing the development of the temporomandibular joint and supporting normal oral functions.
Implementation Method 1
a second compressible lower durometer material, regular or varying in thickness, acting as a full or partial covering layer

AI summary
A biologic-response teether (150). The teether (150) has a shield (160) and one or two generally âTâ-shaped bite portions (170, 180) projecting from the shield (160). The bite portions (170, 180) each define an elongated stem (171, 181) closest to the shield (160) and two arms (169, 168) that are coupled to and transverse to the stem (171, 181).
