Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current teethers on the market have simple structures and basic biting functions, which are inadequate in effectively alleviating teething discomfort in babies.
Innovation Solution
A teether design featuring a liquid storage cavity filled with harmless liquid, a detachable sealing cover for the liquid injection port, and a snap-fit connection between the biting seat and end cap, along with additional structural features for enhanced stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If a liquid storage cavity is added to the teether, then the duration of action is improved, but the device complexity increases
Solution Approach 1:
The liquid storage cavity is nested within the biting seat structure, with the cavity forming an integral part of the teether body. The end cap seals the cavity and includes an injection port that integrates with the existing structure, allowing liquid filling without adding external complex components.
Solution Approach 2:
The teether is designed with a pre-formed liquid storage cavity and injection port structure during manufacturing. The cavity is sealed with an end cap that has a pre-positioned injection port, allowing liquid to be introduced before final use. This preliminary preparation enables extended cooling duration without requiring complex runtime mechanisms.
2Ease of operation
If a detachable sealing cover is provided for the liquid injection port, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The sealing function is segmented into a detachable sealing cover that can be separately removed from the injection port. This allows users to open the port for liquid refilling and close it for sealing, providing ease of operation. The sealing cover is designed as a simple removable component that integrates with the injection port structure.
3Strength
If snap-fit connection with glue is used between biting seat and end cap, then the strength is improved, but the ease of manufacture decreases
Solution Approach 1:
The connection between biting seat and end cap is segmented into a snap-fit mechanical connection with integrated glue application areas. The snap-fit structure provides immediate structural strength, while designated glue regions enhance the bond. This segmented approach balances manufacturing ease with connection strength.
Solution Approach 2:
The connection mechanism combines mechanical snap-fit structure with adhesive bonding, creating a composite connection system. The snap-fit provides structural integrity and positioning, while the glue fills gaps and enhances bonding strength, achieving superior overall connection strength.

AI summary
Disclosed is a teether capable of alleviating teething discomfort, including a teether body. The teether body is made of a soft material. The teether body includes a biting seat and an end cap. The biting seat and the end cap are connected in a sealed manner. A liquid storage cavity for containing harmless liquid is formed in the biting seat, the end cap is provided with a liquid injection port, and the liquid injection port is communicated with the liquid storage cavity. A sealing cover for blocking the liquid injection port is further included, and the sealing cover can be connected with the liquid injection port in a sealed manner. The sealing cover and the liquid injection port can be detachably connected in a sealed manner, which facilitates replacement of the harmless liquid inside the teether body, is cost-effective and has broad application prospects.
