Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dishwashing compositions often leave behind watermarks and spots on dishware due to surface modification during the washing process, particularly on ceramic, stainless steel, plastic, and glass surfaces, as they fail to ensure uniform water drainage and shine.
Innovation Solution
An automatic dishwashing cleaning composition combining a dispersant polymer and a surface-modification surface-substantive polymer, which modifies the dishware surface to reduce contact angles with water, preventing spot formation and enhancing shine by ensuring uniform water drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional dishwashing compositions modify the surface of dishware during washing, then cleaning effectiveness is improved, but water droplets remain on the surface forming spots and watermarks
Solution Approach 1:
The invention changes the surface properties of dishware by modifying the contact angle parameter. The polymers alter the surface energy characteristics, transforming the surface from hydrophobic (high contact angle) to hydrophilic (low contact angle), which enables uniform water drainage and prevents spot formation while maintaining cleaning effectiveness
Solution Approach 2:
The invention uses a composite polymer system combining a dispersant polymer and a surface-modification polymer. This composite approach allows the dispersant polymer to maintain cleaning effectiveness by removing soils, while the surface-modification polymer simultaneously alters surface properties to prevent water droplet beading and spot formation
2Object-affected harmful factors
If water drains uniformly from dishware surface, then spot formation is reduced, but surface modification is required which complicates the composition
Solution Approach 1:
The invention merges multiple functions into a single polymer composition. The dispersant polymer and surface-modification polymer are combined in one formulation, allowing simultaneous achievement of cleaning effectiveness and uniform water drainage. This integrated approach avoids the need for separate treatment steps or additional complex devices
3Object-affected harmful factors
If contact angle with water is reduced on glass surface, then water sheets and drains uniformly preventing marks, but polymer selection and formulation becomes more complex
Solution Approach 1:
The invention focuses on changing the contact angle parameter to less than 50 degrees (preferably less than 48 degrees) through polymer selection and formulation. This specific parameter target guides the choice of polymers with appropriate surface-modifying characteristics, enabling systematic formulation rather than random selection
Solution Approach 2:
The invention uses polymers that create a homogeneous surface modification layer on dishware. The surface-modification polymer forms a uniform coating that consistently reduces contact angle across the entire surface, ensuring uniform water drainage and preventing localized spot formation
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 composition effectively reduces spot formation and enhances the shine of dishware by ensuring that water drains uniformly, addressing the issue of watermarks and spots on various surfaces.
Implementation Method 1
the contact angle with deionized water, measured after a dishwashing cycle in the presence of soil is less than about 50°, preferably less than about 48°. The surface-modification surface-substantive polymer modifies surfaces, such as glass such that water sheets and drains uniformly without leaving marks behind
Implementation Method 2
The dispersant polymer is a sulfonated polymer and the surface-modification surface-substantive polymer... The combination of the two polymers in the composition of the invention provides good cleaning and prevention of spot formation
