Wall-Mounted Changing Station Frame for Excess Load Resistance
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 changing station with a frame that includes a base portion mountable to a wall and a platform portion pivotally coupled to the base, featuring a tubular main section with curved end portions and flat arms that rotate relative to a bracket system, allowing for increased load-bearing capacity through shear and bending resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional resinous or plastic materials are used for the base and platform, then the device complexity and manufacturing cost are reduced, but the load-bearing strength and safety are insufficient when excess weight is applied
Solution Approach 1:
The base is divided into a base portion and a base cover, where the base portion provides structural strength and the base cover provides functionality. The platform is divided into a platform portion and a platform cover, separating structural support from user interface elements. This segmentation allows each component to be optimized for its specific function.
Solution Approach 2:
The base portion and platform portion are formed from metal materials (such as aluminum alloy) to provide high strength-to-weight ratio and exceed load-bearing requirements, while the base cover and platform cover can use lower-strength materials like resinous or plastic materials for aesthetic and functional purposes.
2Reliability
If the base and platform are made from stronger materials to withstand excess loads, then the load-bearing capacity and safety are improved, but the manufacturing cost and material weight increase
Solution Approach 1:
Metal materials (such as aluminum alloy) are used for the base portion and platform portion to provide high strength-to-weight ratio, ensuring the structure can withstand excess loads while minimizing unnecessary weight. The use of metal allows for thinner, lighter sections compared to conventional plastic materials.
Solution Approach 2:
The base portion and platform portion incorporate curved surfaces and rounded edges, which distribute stress more evenly throughout the structure. This curvature design enhances structural integrity and load-bearing capacity while maintaining a sleek, modern appearance.
3Reliability
If the base and platform are made from stronger materials to withstand excess loads, then the load-bearing capacity and safety are improved, but the manufacturing cost increases
Solution Approach 1:
The base is divided into a base portion and a base cover, and the platform is divided into a platform portion and a platform cover. This segmentation allows the metal structural components to be manufactured separately and then assembled with the cover components, enabling modular production and reducing overall manufacturing complexity.
Solution Approach 2:
The platform portion is designed to be movable relative to the base portion, allowing the platform to pivot between a horizontal position and an inclined position. This dynamic design provides functional versatility while the metal construction ensures safety under various load conditions.

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.
