Wall-Mounted Changing Station Frame for Higher Load Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional baby changing stations often fail to withstand excess loads, such as an adult's weight or multiple children, leading to potential injuries due to their weight limitations.
Innovation Solution
A baby supporting device with a frame having a pivotally coupled platform and a base portion, featuring a rotatable section, arms, and stop members that allow the platform to rotate and pivot relative to the base, supported by brackets and an actuator for self-closing functionality, enhancing load-bearing capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional baby changing stations use resinous or plastic materials for the base and platform, then the device complexity is reduced and manufacturing is easier, but the load-bearing capacity is insufficient and the station may fail under excess weight
Solution Approach 1:
The patent divides the baby changing station into separate functional components: a base portion mounted to the wall, a platform portion for supporting the baby, brackets for connection, and stop members for positioning. This segmentation allows each component to be optimized independently - the base and brackets can be made from stronger materials while maintaining overall structural integrity and reducing complexity through modular design.
Solution Approach 2:
The patent employs composite construction by combining different materials with complementary properties. The base portion and brackets are made from stronger materials (such as metal) to provide structural support and load-bearing capacity, while the platform portion can use lighter materials. This composite approach increases strength without uniformly increasing device complexity throughout the entire structure.
2Strength
If the platform is hingedly mounted directly to the base, then the device complexity is minimized, but the load distribution is inadequate and the station cannot withstand excess loads
Solution Approach 1:
The patent introduces brackets as intermediary components between the base portion and the platform portion. These brackets serve as mediators that distribute loads more effectively across the structure. The brackets are positioned to optimize load transfer paths and work in conjunction with stop members to control platform movement, thereby enhancing load distribution capacity while adding only moderate structural complexity.
3Strength
If stronger materials are used throughout the entire station, then the load-bearing capacity increases, but the manufacturing cost and weight increase
Solution Approach 1:
The patent applies the principle of local quality by using stronger materials specifically where needed - in the base portion and brackets that bear the primary structural loads - while allowing the platform portion to use lighter materials. This localized strengthening approach increases overall load-bearing capacity without unnecessarily increasing the weight of the entire station, optimizing the strength-to-weight ratio.

AI summary
A baby supporting device is provided which includes a frame. The frame includes a first portion for mounting onto a wall and a second portion pivotally coupled to the first portion and rotatable between a first position and a second position. A first stop member extends from the first portion, and a second stop member extends from the second portion, such that when the second stop member engages the first stop member it stops the second portion at the second position. A first surface covers at least a portion of the first portion, and a second surface covers at least a portion of the second portion.
