Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional pet pee pads are used with open edges, then the structure is simple and easy to manufacture, but urine flows out from unenclosed edges affecting environmental hygiene
Solution Approach 1:
The side enclosing assembly is divided into multiple independent components: first side enclosing members connected to the absorbent layer, second side enclosing members connected to the first members, and elastic members providing flexible connection. This segmentation allows each component to perform its specific function while maintaining overall leak prevention capability.
Solution Approach 2:
The side enclosing members are nested within the overall pad structure, with the first side enclosing members positioned between the second side enclosing members and the absorbent layer. This nested arrangement maximizes space utilization and ensures effective urine containment within the pad boundaries.
2Object-affected harmful factors
If side enclosing members extend beyond the impermeable layer edges, then urine containment is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The side enclosing members are designed with different lengths relative to the impermeable layer edges. The first side enclosing members extend beyond the impermeable layer edges to ensure containment, while the second side enclosing members have varying lengths to optimize both containment and manufacturing ease. This local differentiation of dimensions allows effective urine containment without requiring uniform high precision across all edges.
3Adaptability or versatility
If elastic members are added to connect side enclosing members, then flexibility and adaptability improve, but device complexity increases
Solution Approach 1:
Elastic members are used to connect the side enclosing members, providing flexible adaptation to different pad sizes and shapes. These elastic components can stretch and conform to the specific geometry of the absorbent layer and impermeable layer, ensuring effective urine containment while accommodating manufacturing variations and different usage scenarios.
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
Effectively contains urine within the pad, reducing the impact on environmental hygiene by intercepting and absorbing it, even with excessive amounts.
Implementation Method 1
an absorbent layer, where the absorbent layer is provided on a surface of the impermeable layer
Implementation Method 2
a side of each of the two first side enclosing members adjacent to a center of the impermeable layer and a side of each of the two second side enclosing members adjacent to the center of the impermeable layer are fixedly connected to elastic members, respectively

AI summary
A leak-proof pee pad includes an impermeable layer; an absorbent layer provided on a surface of the impermeable layer; and a side enclosing assembly connected to the impermeable layer and/or the absorbent layer. The side enclosing assembly is provided on the impermeable layer or the absorbent layer, so that the side enclosing assembly can intercept urine flowing to an edge of the absorbent layer, preventing the urine from flowing to the ground and reducing the impact of the urine on environmental hygiene.
