Portable diaper changing pad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable diaper changing pads are prone to spreading or having corners exposed when carried vertically or hung on a stroller due to the storage portion falling out, causing inconvenience and occupying excessive space.
Innovation Solution
A portable diaper changing pad with a body portion and four side portions connected by first and second connecting structures, allowing it to be folded into a compact state without spreading, with storage portions supported to prevent falling and exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hanging cord is disposed at the corner of the folded changing pad, then the changing pad can be hung vertically on a baby stroller, but the storage portion falls out due to gravity causing the folded changing pad to spread
Solution Approach 1:
The patent applies preliminary anti-action by providing connecting structures (fasteners, buttons, or zippers) that preemptively counteract the gravitational force causing the storage portion to fall out. These connecting structures are designed to secure the storage portion to the body portion before any spreading can occur, preventing the harmful effect rather than correcting it after it happens.
Solution Approach 2:
The patent merges the storage portion and body portion into a unified secured structure through connecting structures. This combination ensures that when the changing pad is folded and hung vertically, the storage portion remains firmly attached and cannot fall out, maintaining the compact folded shape while enabling vertical hanging.
2Stability of the object's composition
If the hanging cord is disposed at the wide side of the folded changing pad, then the opening does not face downward preventing storage portion from falling, but the changing pad must be placed horizontally occupying excessive space
Solution Approach 1:
The patent applies dynamics by making the changing pad adaptable to different carrying orientations. The connecting structures enable the changing pad to maintain its compact folded shape whether carried horizontally or hung vertically, allowing optimal orientation selection based on carrying conditions rather than being constrained to a single position.
Solution Approach 2:
The patent changes the orientation parameter of the folded changing pad from fixed horizontal placement to variable positioning. The connecting structures enable the changing pad to maintain structural integrity across different orientations (horizontal carrying or vertical hanging), allowing the opening to face in different directions without compromising storage portion retention.
3Adaptability or versatility
If the storage portion is provided on the foldable changing pad for carrying essentials, then parents can take all essentials at a time, but the storage portion falls out when folded causing the changing pad to spread
Solution Approach 1:
The patent applies preliminary anti-action by equipping the storage portion with connecting structures (fasteners, buttons, or zippers) that preemptively counteract the gravitational force causing it to fall out. These structures are designed to secure the storage portion to the body portion before any spreading can occur during folding or vertical hanging.
Solution Approach 2:
The patent merges the storage portion and body portion into a unified secured structure through connecting structures. This combination ensures that when the changing pad is folded, the storage portion remains firmly attached and cannot fall out, maintaining the compact folded shape while preserving full storage functionality for carrying essentials.

AI summary
A portable diaper changing pad comprises a body portion as well as a first portion, a second portion, a third portion, and a fourth portion that are connected to the body portion together. In a used state, the changing pad is completely unfolded, and the first, second, third and fourth portions are respectively disposed on four sides of the body portion, such that a baby can lie thereon. The first and second portions, and the third and fourth portions serve as two groups of two opposite portions. In a carried state, the changing pad is completely folded, and under an action of connection of a first connecting structure and a second connecting structure that are respectively disposed on two opposite positions in at least one group, the two portions are connected together, such that the changing pad can be kept in the carried state without spreading.
