Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If pea dregs cat litter is used, then organic composition is provided, but rotten odor is generated due to corruptible components in high-humidity environment
Solution Approach 1:
The patent changes the chemical composition parameters by replacing organic pea dregs with inorganic materials (bentonite, diatomaceous earth, zeolite) that do not contain corruptible components, thereby eliminating the source of rotten odor while maintaining litter functionality
Solution Approach 2:
The patent creates a composite litter formulation combining multiple inorganic materials (bentonite, diatomaceous earth, zeolite) with agglomeration agents and deodorizing agents to achieve both odor prevention and deodorizing effects simultaneously
2Quantity of substance
If bentonite cat litter is used, then water absorption is improved, but dust is generated causing health risks
Solution Approach 1:
The patent combines bentonite with diatomaceous earth and zeolite in a composite formulation that maintains the water absorption benefits of bentonite while the other inorganic components reduce dust generation and improve overall safety
Solution Approach 2:
The patent applies different materials in specific proportions within the composite litter, placing dust-reducing inorganic materials (diatomaceous earth, zeolite) in conjunction with bentonite to locally address the dust issue while preserving water absorption capabilities
3Quantity of substance
If crystal cat litter is used, then water absorption is provided, but agglomeration is poor making it inconvenient to use and discharge
Solution Approach 1:
The patent incorporates agglomeration agents (carboxymethyl cellulose, guar gum, starch) into the crystal litter composite to enable clumping functionality while maintaining the water absorption properties of the inorganic base materials
Solution Approach 2:
The patent merges the water absorption function of crystal litter with the agglomeration function of natural gums and starches to create a unified litter product that performs both functions effectively
4Weight of stationary object
If confetti cat litter is used, then lightweight structure is provided, but water absorption and agglomeration are poor
Solution Approach 1:
The patent creates a composite formulation where lightweight inorganic materials (diatomaceous earth, zeolite) are combined with high water-absorption materials (bentonite, polyacrylates) and agglomeration agents to achieve both light weight and effective water absorption
