Motorized Folding Changing Table for One-Hand Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for portable, non-bulky, and safe diaper changing tables that can support children weighing at least 40 pounds and can be operated with one hand, as existing solutions require both hands to set up and may not be available in all environments.
Innovation Solution
A portable changing table design featuring pivotable panels with a motorized mechanism that allows the table to be completely opened and folded with one hand, including a handle that pivots for easy operation and a power source to power the motor, ensuring the table can be set up and folded safely while holding a child.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a portable diaper changing table is designed to be compact and easy to carry, then it becomes bulky and difficult to maneuver, but if it is designed to be strong enough to support children weighing at least 40 pounds, it becomes larger and more difficult to carry
Solution Approach 1:
The changing table is divided into three separate panels (left, middle, right) that can be folded relative to each other. This segmentation allows the table to maintain structural strength when assembled while collapsing into a compact form for portability, directly resolving the contradiction between support capacity and ease of carrying.
Solution Approach 2:
The table incorporates pivotable connections between panels that enable dynamic transformation between an extended configuration (providing strength and stability for supporting children) and a collapsed configuration (reducing volume for easy carrying). This dynamic adaptability resolves the contradiction by allowing the structure to change its properties based on operational needs.
2Ease of operation
If the changing table is designed to be operated with one hand, then it becomes easier to use while holding a child, but it requires a more complex mechanism involving motors and power sources
Solution Approach 1:
The manual mechanical folding mechanism is replaced with an automated motorized system. Motors are integrated into the pivot connections between panels, enabling automatic opening and closing actions that would otherwise require complex manual coordination. This substitution achieves one-hand operation by replacing the need for complex manual mechanical manipulation with automated motor control.
Solution Approach 2:
The table incorporates self-service features through automated motors that perform the opening and closing actions independently of user effort. The system uses sensors and control logic to automatically execute folding and unfolding sequences, reducing the operational burden on the user to minimal one-hand activation while managing the complexity through integrated control systems.
3Loss of time
If the changing table is designed to be quickly deployed, then it becomes more useful in urgent situations, but it may compromise the stability and strength needed to support children
Solution Approach 1:
The dynamic pivotable panel design enables rapid deployment through controlled rotation movements. The same dynamic mechanism that allows quick transformation from collapsed to extended state also ensures proper structural alignment and locking, maintaining stability while reducing deployment time. The motorized assistance further accelerates the deployment process without compromising structural integrity.

AI summary
A portable, folding table that is particularly suited for changing a child's diaper is provided. The table includes a left panel, a middle panel, and a right panel and has an extended position in which the panels are substantially co-planar and a collapsed position in which the left and right panels fold between about 90 and about 180 degrees relative to the middle panel. The table optionally includes a handle attached to the front or rear side of the middle panel, legs attached to the left and right panels, and motors to move the panels between the extended and collapsed positions. Optionally, the left or right panel includes a bottom flange that serves as a leg and further serves to hide the other panels when the table is in the collapsed position.
