The patent extracts the urine discharge function from the traditional absorption-only system. By providing a discharge opening in the bottom surface and configuring the bottom surface to be inclined, urine is actively directed outward through the opening, separating the urine removal function from the absorption function. This extraction of the discharge mechanism resolves the contradiction by preventing urine accumulation and odor generation while maintaining containment through the absorbent sheet.

Instead of relying solely on absorption to contain urine (traditional approach), the patent inverts the approach by actively discharging urine through a bottom opening. The bottom surface is configured to incline toward the discharge opening, reversing the conventional upward containment strategy. This inversion effectively prevents urine odor by removing urine before it can accumulate and generate odor, while the absorbent sheet still provides secondary containment.

The patent merges the discharge opening configuration with the bottom surface structure itself. The bottom surface is designed to be inclined toward the discharge opening, integrating the flow-directed function into the structural form rather than adding separate mechanical components. This merging approach achieves effective urine discharge and odor prevention while minimizing structural complexity.

The inclined bottom surface configuration enables self-service urine discharge without requiring external power sources, pumps, or complex control mechanisms. Gravity naturally directs urine toward the discharge opening due to the inclined surface, making the system self-regulating and simple in structure. This self-service approach resolves the contradiction by achieving odor prevention through passive gravitational flow rather than active mechanical systems.
