Bite-Proof Spout With Multi-Durometer Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottles with spouts are prone to damage and irregular flow due to repeated biting, especially by young children, as they lack effective bite protection mechanisms.
Innovation Solution
A bottle design featuring a pivoting cover with a middle band of higher durometer material acting as a bite guard, providing tactile and visual differentiation, and a flexible strap for easy operation, combined with a secure snap-fit mechanism to prevent accidental opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional spout is used in a bottle, then the bottle is simple in structure and easy to manufacture, but the spout becomes damaged or weakened after repeated biting by young children
Solution Approach 1:
The spout is divided into multiple sections with different durometer values: a softer lower portion for comfort and a harder upper portion for bite resistance. This segmentation allows each part to perform its specific function while maintaining overall structural integrity and preventing damage from repeated biting.
Solution Approach 2:
Different portions of the spout are assigned different material properties (durometer values) based on their functional requirements. The upper portion has higher durometer for bite protection, while the lower portion has lower durometer for comfort, creating local quality variations that solve the durability problem without requiring complete structural redesign.
2Adaptability or versatility
If a single-durometer spout material is used, then the manufacturing process is simple, but the spout cannot provide both comfort and bite protection simultaneously
Solution Approach 1:
The spout is constructed as a composite structure with multiple materials or material densities having different durometer values. This composite approach enables the spout to provide both comfort (softer material) and bite protection (harder material) within a single component, enhancing functionality while using established composite manufacturing techniques.
3Reliability
If the entire spout is made of hard material for bite protection, then the spout resists biting damage, but the spout becomes less comfortable for children's mouths
Solution Approach 1:
The spout implements local quality by making only the upper portion (exposed to biting) of higher durometer for bite resistance, while the lower portion remains softer for mouth comfort. This localized differentiation allows the spout to provide both bite protection and comfort without compromising either function.
Solution Approach 2:
The spout is segmented into distinct zones with different hardness levels: a harder upper zone for bite protection and a softer lower zone for comfort. This segmentation ensures that the hard material is positioned only where needed for bite resistance, while the soft material contacts the child's mouth for comfort.

AI summary
A bite-proof spout is disclosed which contains multiple durometer material, such that the higher durometer material is in closer contact to the mouth of a user to be able to withstand biting without undue deterioration than the lower durometer material which is positioned further away from the mouth.
