Changing table placed on a ground or a table and capable of weighting a child
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant scales are single-purpose, uncomfortable for children due to hard plastic materials, and lack the ability to measure feeding intake.
Innovation Solution
A changing table with a frame, weighting module, and fabric component that includes load sensors and a display device, allowing for weight measurement before and after feeding to calculate feeding intake, and can be installed on a play yard, table, or ground for convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated infant scale or standard bathroom scale is used, then weight measurement function is provided, but the product is single-purpose with no other use around the home
Solution Approach 1:
The changing table is designed to perform multiple functions: it serves as both a changing table and a weighing scale. The weighing module is integrated into the changing table structure, allowing it to function as a scale when needed while maintaining its primary function as a changing table, thus eliminating the need for separate single-purpose products
Solution Approach 2:
The patent combines the weighing function with the changing table by integrating the weighing module (including load sensors and display) into the changing table structure. This merging of functions allows the single device to serve both purposes without requiring separate products
2Object-affected harmful factors
If a conventional scale made of hard plastic material is used, then weight measurement is enabled, but children feel uncomfortable
Solution Approach 1:
The changing table uses a fabric component instead of hard plastic material. The fabric provides a soft, comfortable surface for the child while still allowing the load sensors to detect weight changes. This flexible material choice improves child comfort without significantly complicating manufacturing
3Adaptability or versatility
If a conventional scale is used, then weight measurement is provided, but it does not offer a feature to measure a feeding intake of a child
Solution Approach 1:
The system uses the weighing module to measure the child's weight before and after feeding, then calculates the feeding intake by comparing the two measurements. The display device provides feedback showing both the weight change and the calculated feeding intake, enabling parents to track feeding amounts without additional measurement devices
Solution Approach 2:
The system performs preliminary weight measurement before feeding, then performs another measurement after feeding. By taking these preliminary and subsequent measurements, the system can calculate the feeding intake as the difference between the two weights, adding functionality without requiring complex direct measurement mechanisms
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides a comfortable and convenient way to track a child's weight and feeding intake by using load sensors and a display device, offering a multi-purpose solution for caregivers.
Implementation Method 1
The weighting module includes four load sensors disposed on four corners of the frame and between the lower frame and the upper frame

AI summary
A changing table, which is placed on a ground or a table and capable of weighting a child, includes a frame, a weighting module and a fabric component. The frame includes a lower frame including a supporting portion for supporting the changing table on a surface of the ground or the table, and an upper frame movably installed on the lower frame. The weighting module includes four load sensors disposed on four corners of the frame and between the lower frame and the upper frame. The fabric component covers the upper frame to form a supporting area for supporting the child. The changing table can measure a first weight of the child before feeding the child and further measure a second weight of the child after feeding the child, so as to determine a difference of the second weight and the first weight of the child as the feeding intake.
