Infant food chewing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant food chewing devices are prone to separation during use, leading to a risk of the silica gel net being swallowed due to inadequate fixation, especially when infants bite too deeply, causing the upper and lower parts to separate and the net to detach.
Innovation Solution
The infant food chewing device incorporates a net bag, a cover, and a fixing hoop, where the fixing hoop is detachably connected to the cover and net bag, with an enclosing wall that shields the hoop, reducing the effective biting area and increasing the connection strength, thus preventing the net bag from detaching and minimizing the risk of swallowing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the upper body part and lower body part are assembled with a fastener, then the device can be easily assembled and disassembled, but the connection strength is insufficient when the infant bites too deeply
Solution Approach 1:
The device is divided into an upper body part, lower body part, and a separate fixing hoop component. The fixing hoop acts as an intermediate element that strengthens the connection between the upper and lower body parts while maintaining easy assembly through snap-fit mounting.
Solution Approach 2:
The fixing hoop serves as an intermediary component between the upper body part and lower body part. It provides enhanced connection strength through its hoop structure while allowing easy assembly via snap-fit engagement with the body parts.
2Ease of operation
If the silica gel net is made small for better control, then the device is easier to handle, but the risk of accidental swallowing increases
Solution Approach 1:
The enclosing wall is pre-formed as an integral part of the lower body part, creating a protective barrier before the infant can access the silica gel net. This preliminary protective structure prevents direct access to the net while maintaining device functionality.
Solution Approach 2:
The potential harm of the infant accessing the silica gel net is converted into a benefit by using the infant's own biting force against the enclosing wall as a protective barrier, which redirects the force away from the net while maintaining chewing functionality.
3Strength
If the fixing hoop is exposed for better connection, then the connection between net bag and cover is stronger, but the infant can bite directly on the hoop causing separation
Solution Approach 1:
The enclosing wall acts as an intermediary protective barrier between the infant's teeth and the fixing hoop. It absorbs and redirects the biting force away from the hoop while maintaining the hoop's structural connection function.
Solution Approach 2:
The enclosing wall is pre-formed as an integral part of the lower body part, creating a protective barrier before the infant can access the fixing hoop. This preliminary protective structure prevents direct biting on the hoop while maintaining device functionality.

AI summary
An infant food chewing device includes a net bag, a cover, and a fixing hoop. The net bag includes a bag body having a receiving cavity. A cavity wall of the receiving cavity is provided with several through holes. A first fixing ring extends from one side of an open end of the bag body. The cover includes a cover body having a mounting side surface. An enclosing wall and a blocking block are disposed on the mounting side surface. The blocking block is located in an annular area of the enclosing wall. The blocking block has a blocking side face abutting an end face of the open end and blocking the open end. The fixing hoop is sleeved on the outer periphery of the blocking block and the first fixing ring. The enclosing wall at least partially shields the outer side surface of the fixing hoop.
