Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pelletized agricultural fiber compositions for liquid solidification and moisture retention are too dense, requiring crumbling to achieve immediate performance, leading to dust and transportation issues, and there is a need for a cost-effective, uniformly sized alternative.
Innovation Solution
A pelletized composition comprising at least 60% agricultural fibers and 0.1-20% superabsorbent polymer, with a density of less than 40 lbs/cubic foot, produced using a pellet mill to form substantially uniform pellets, eliminating the need for crumbling and enhancing pneumatic transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If pelletized agricultural fiber compositions are made with high density for compact transportation, then transportation efficiency is improved, but the pellets require crumbling to achieve immediate performance and generate dust
Solution Approach 1:
The patent changes the density parameter of the pellets from high density (requiring crumbling) to low density (less than 40 lbs/cubic foot). This parameter change allows the pellets to be used immediately without crumbling, eliminating dust generation while maintaining efficient transportation
Solution Approach 2:
The patent creates pellets that are designed to be used in their original form without requiring additional processing (crumbling). The pellets are disposable absorption materials that perform their function immediately upon contact with liquid, eliminating the need for complex handling procedures
2Volume of stationary object
If pellets are made with high density for compact form, then storage space is reduced, but immediate performance is not achieved without crumbling
Solution Approach 1:
The patent changes the density parameter to less than 40 lbs/cubic foot, which maintains compact form for efficient storage while enabling the pellets to perform immediately without requiring crumbling. This parameter optimization resolves the contradiction between compact storage and immediate performance
3Reliability
If existing pelletized compositions are used, then liquid solidification capability is achieved, but the process requires additional crumbling step and generates transportation issues
Solution Approach 1:
The patent extracts the crumbling step from the necessary process sequence. By designing pellets with low density (less than 40 lbs/cubic foot), the invention removes the requirement for crumbling while maintaining liquid solidification capability, thereby simplifying the overall process
Solution Approach 2:
The pellets are designed to be self-sufficient and perform their liquid solidification function immediately upon contact with liquid. The low-density formulation allows the pellets to work effectively without requiring additional processing equipment or steps, making the system self-service and reducing complexity
