Animal Litter with Segmented Color-Changing and Fragrance Particles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing animal toilet sand that changes color upon moisture absorption is difficult to use for recognizing urine absorption areas and observing urine color due to color changes from sprayed fragrances, making it hard to distinguish between urine color and sand color changes.
Innovation Solution
The development of animal toilet sand with color change particles featuring a stained core portion made from pulp and a covering layer with highly absorbent resin, where the core portion is darker than the waste material, and white particles that maintain their color and absorb fragrance, allowing easy urine recognition and odor suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If liquid fragrance is sprayed onto animal toilet sand to improve scent releasing effect, then odor suppression is improved, but the sand changes color due to the sprayed liquid making urine color observation difficult
Solution Approach 1:
The invention divides the sand particles into two distinct types: color change particles (without fragrance) and white particles (with fragrance). This segmentation allows the fragrance function and color observation function to be separated, so that white particles provide odor suppression while color change particles enable clear urine color observation without interference from fragrance liquid staining.
Solution Approach 2:
The fragrance component is extracted from the color change particles and placed only in the white particles. This extraction ensures that the color change particles remain free from fragrance liquid staining, allowing accurate urine color observation, while the white particles continue to provide odor suppression through their fragrance content.
2Difficulty of detecting and measuring
If animal toilet sand changes color upon moisture absorption to facilitate recognition of urinated area, then area recognition is improved, but urine color observation becomes difficult due to sand color changes
Solution Approach 1:
The invention segments the sand into color change particles for area recognition and white particles for urine color observation. The color change particles enable easy identification of urinated areas through their color transformation, while the white particles serve as a stable background that allows clear observation of urine color without interference from sand color changes.
3Measurement precision
If white animal toilet sand is used to enable visual observation of urine color, then urine color observation is improved, but recognition of urinated area becomes less effective without color change indication
Solution Approach 1:
The invention merges two types of particles with complementary functions into a single animal toilet sand product. The color change particles provide urinated area recognition through color transformation, while the white particles provide urine color observation capability. Together, they create a composite system that delivers both functions simultaneously.
Solution Approach 2:
The animal toilet sand achieves multi-functionality by incorporating both color change particles and white particles. This allows the same product to simultaneously provide urinated area recognition (through color change particles) and urine color observation (through white particles), eliminating the need to choose between these two functions.
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
The solution enables easy recognition of urine absorption areas, clear observation of urine color, and effective odor suppression by using color change particles with a pulp-based core and resin covering layer, and white particles that absorb and retain fragrance, improving user experience and hygiene.
Implementation Method 1
a covering layer which is configured to include pulp and highly absorbent resin and to cover the stained core portion and mask the color of the stained core portion; and the color of the stained core portion comes out when the covering layer absorbs moisture
Implementation Method 2
Animal toilet sand that changes color upon absorption of moisture such as urine has been proposed heretofore in order to facilitate recognition of a urinated area
Implementation Method 3
The particulates include a deodorant

AI summary
To provide animal toilet sand that allows easy recognition of an area where urine has been absorbed, easy observation of the color of urine, and suppression of odor of excreted urine. An animal toilet sand is composed of a plurality of particulates having a water absorbing property, wherein the particulates include: color change particles that are configured to include pulp and to change color upon absorbing moisture; and white particles that have a core portion which is configured to include pulp and a covering layer which is configured to include pulp, highly absorbent resin and fragrance, and to cover the core portion, the white particles not changing color upon absorbing moisture, and the color change particles are included at a higher ratio by weight than the white particles.
