Pet absorbent sheet with segmented color patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pet absorbent sheets with designs often fail to clearly differentiate between urine-absorbed and non-urine-absorbed regions, making it difficult for users to determine when to replace the sheet, especially when pets discharge urine unevenly.
Innovation Solution
A pet absorbent sheet design featuring colored portions on the back-surface side that are visible from the top-surface side, with distinct color patterns and configurations to distinguish between used and unused areas, including pet face patterns to identify target pets, and non-target patterns to avoid confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the entire absorbent body is covered with design patterns to enhance decorativeness and urine-covering performance, then the aesthetic appearance is improved, but users cannot easily differentiate urine-absorbed regions from non-urine-absorbed regions
Solution Approach 1:
The absorbent body is divided into multiple regions with different design patterns. Specifically, a first region has a first design pattern while a second region has a second design pattern that differs from the first. This segmentation allows users to visually distinguish between urine-absorbed and non-urine-absorbed regions while maintaining aesthetic appearance throughout the entire absorbent body.
2Object-generated harmful factors
If design patterns are applied throughout the entire absorbent body, then urine-covering performance is enhanced, but it becomes difficult to identify when the sheet needs replacement
Solution Approach 1:
Different regions of the absorbent body are assigned different design patterns locally. The first region contains a first design pattern and the second region contains a second design pattern. When urine is absorbed, users can easily identify the used region by the change in appearance against the contrasting design patterns, while the entire surface maintains aesthetic coverage.
3Shape
If the absorbent body is fully covered with design to improve appearance, then decorativeness is enhanced, but differentiation between used and unused areas becomes difficult
Solution Approach 1:
The design patterns in different regions are made asymmetric or distinctly different from each other. The first design pattern differs from the second design pattern in terms of pattern type, color, or arrangement. This asymmetry creates visual contrast that makes it easy to detect which region has absorbed urine, while the entire surface remains decoratively covered.
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
Enables easy identification of urine-absorbed regions and non-urine-absorbed regions, facilitating timely replacement and reducing the risk of mistaken usage, while enhancing designability and urine-covering performance.
Implementation Method 1
colored portions that are disposed on a back-surface side of the top-surface sheet and are visible from a top-surface side of the top-surface sheet
Implementation Method 2
an absorbent body provided between the top-surface sheet and the back-surface sheet

AI summary
A pet absorbent sheet having a thickness direction, a first direction orthogonal to the thickness direction, and a second direction orthogonal to the thickness direction and the first direction includes: a top-surface sheet disposed on a top-surface side; a back-surface sheet disposed on a back-surface side; an absorbent body disposed between the top-surface sheet and the back-surface sheet; and colored portions disposed on a back-surface side of the top-surface sheet and that are visible from a top-surface side of the top-surface sheet. A region that overlaps the absorbent body includes: colored regions where the colored portions are disposed; and a non-colored region where the colored portions are not disposed between the colored regions in the first direction. The non-colored region is disposed throughout an entire region of the absorbent body in the second direction.
