Changing table, play yard assembly with changing table and method of measuring feeding intake by changing table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional infant scales are single-purpose, uncomfortable for children due to hard plastic material, and lack the ability to measure feeding intake.
Innovation Solution
A changing table with a detachable play yard assembly that includes a frame, weighting module with load sensors, and a fabric component, allowing for comfortable weight measurement and calculation of feeding intake by measuring the child's weight before and after feeding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dedicated infant scale is used for weight measurement, then weight measurement function is achieved, but the product becomes single-purpose with no other use around the home
Solution Approach 1:
The patent integrates multiple functions into a single device: the changing table serves as both a changing station and a weighing device. The scale is built into the changing table structure, allowing it to perform both changing and weighing functions, thereby achieving multi-functionality without requiring separate dedicated devices.
2Object-affected harmful factors
If a conventional scale made of hard plastic material is used, then weight measurement is achieved, but children become uncomfortable
Solution Approach 1:
The patent uses a fabric component instead of hard plastic material for the weighing surface. The fabric material provides flexibility and comfort for the child while still allowing the load sensors to accurately measure weight. This replaces the traditional hard plastic scale surface with a soft, comfortable alternative.
3Adaptability or versatility
If a conventional scale is used, then weight measurement is achieved, but the scale does not offer a feature to measure feeding intake
Solution Approach 1:
The system automatically performs multiple measurements and calculates feeding intake without requiring manual intervention. The control unit automatically records weight before and after feeding, calculates the difference, and displays the feeding intake amount, thereby providing enhanced measurement capabilities through automated self-service operation.
4Measurement precision
If load sensors are installed between lower frame and upper frame, then weight measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the weighing function with the changing table structure by integrating load sensors into the frame connection points. The four load sensors are positioned at the corners where the upper and lower frames connect, merging the support structure with the measurement function to achieve precise weight measurement without adding separate complex weighing 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
Enables caregivers to track a child's feeding intake effectively while providing a comfortable and versatile solution that can be used both with and without the play yard, offering precise weight measurements.
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 is detachably installed on a play yard and capable of weighting a child. The changing table includes a frame, a weighting module and a fabric component. The frame includes a lower frame and an upper frame. The lower frame is detachably installed on the play yard. The upper frame is movably installed on the lower frame. The weighting module comprises 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.
