Segmented Water Absorption Grains for Odor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional water absorption treatment materials that absorb malodorous substances require a significant amount of metal compounds for deodorizing functions, increasing manufacturing costs.
Innovation Solution
A water absorption treatment material comprising two types of grains: one with a metal deodorizing function and the other without, where the metal is only present in a portion of the grains, allowing for reduced metal usage and effective odor suppression across both grain types.

Engineering Contradiction Analysis
1Object-affected harmful factors
If metal compound is contained in each grain for deodorizing function, then odor suppression is improved, but manufacturing cost increases due to increased metal material usage
Solution Approach 1:
The treatment material is segmented into two distinct grain types: first grains containing metal compound for deodorizing, and second grains without metal compound. This segmentation allows the metal to be concentrated in specific locations rather than distributed throughout all grains, reducing overall metal usage while maintaining deodorizing effectiveness through the localized first grains interacting with malodorous substances in the vicinity.
Solution Approach 2:
Different regions of the treatment material are assigned different properties: first grains have deodorizing function with metal compound, while second grains provide water absorption without metal. This local differentiation optimizes the overall performance by placing metal only where deodorizing is most needed, reducing total metal consumption while maintaining effective odor suppression coverage.
2Reliability
If metal compound is contained in each grain, then deodorizing function is improved, but manufacturing cost increases
Solution Approach 1:
The treatment material is divided into first grains with metal compound and second grains without metal compound. This segmentation reduces the total quantity of expensive metal material required while maintaining reliable deodorizing function through the distributed first grains that interact with malodorous substances as they move through the treatment material.
Solution Approach 2:
The invention changes the parameter of metal distribution from uniform (in all grains) to non-uniform (only in first grains). This parameter change reduces the total metal content while maintaining effective deodorizing coverage, thereby lowering manufacturing costs without sacrificing deodorizing reliability.
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 the production of a cost-effective water absorption treatment material that effectively suppresses odor generation after use by utilizing the deodorizing action of the metal in the first grain on both grain types, thereby reducing metal material costs and maintaining odor control.
Implementation Method 1
the deodorizing action of the metal contained in the first grain is also exerted on the second grain around the first grain

AI summary
A water absorption treatment material absorbs a liquid containing a malodorous substance, and includes a first grain and a second grain. The first grain contains a metal having a deodorizing function. The second grain does not contain a metal having a deodorizing function.
