Antiskid Container Bottom Coating for Thin, Peel-Resistant Grip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ceramic and glass containers with smooth bottoms tend to skid easily on dinner plates, posing a fall risk, and existing antiskid solutions like silicone cords are either visually unappealing or prone to peeling, especially on enameled ceramic surfaces.
Innovation Solution
A method of manufacturing containers with a bottom wall featuring an antiskid pattern of grooves and projections, where a fluid antiskid material is applied and solidified to form a strong, stable coating that minimizes peeling risks and maintains visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a silicone cord is deposited on the bottom of the container to prevent skidding, then the container gains antiskid properties, but the cord has large thickness (superior to 1 mm) which deteriorates the visual aspect and aesthetic appeal
Solution Approach 1:
The patent changes the thickness parameter of the antiskid coating from superior to 1 mm (silicone cord) to inferior to 0.5 mm (deposited coating). This is achieved by changing the application method from pre-formed cord to fluid deposition followed by controlled solidification, allowing precise control of the final thickness parameter while maintaining antiskid functionality.
Solution Approach 2:
The patent replaces the mechanical silicone cord system with a chemical deposition and solidification system. Instead of applying a pre-formed mechanical cord, the invention uses fluid antiskid material deposition followed by in-situ solidification (vulcanization or polymerization), substituting a mechanical application approach with a chemical process that enables thinner, more uniform coatings.
2Reliability
If a silicone cord is used on ceramic objects, then the container gains antiskid properties, but the cord is prone to loss of cohesion and peeling at the lips
Solution Approach 1:
The patent changes the physical state parameter of the antiskid material from solid cord to fluid, then to solidified coating. The fluid state allows the material to flow and conform to the substrate surface, ensuring complete wetting and contact. After solidification, this creates a cohesive bond throughout the coating thickness, eliminating the peeling issue at the lips that occurs with pre-formed cords.
Solution Approach 2:
The patent uses the fluid antiskid material as an intermediary that mediates between the container bottom and the support surface. The fluid state allows it to adapt to surface irregularities and form intimate contact, while the subsequent solidification locks this contact in place, creating a stable, peeling-resistant bond that acts as an effective intermediary between the container and support.
3Adaptability or versatility
If the enamel of the base of a ceramic article is removed to allow cooking, then the article can be used for cooking, but the microroughness and surface micro-porosity of the crock reduce the adherence of silicone resins
Solution Approach 1:
The patent changes the state of the antiskid material from pre-formed solid cord to fluid, then to solidified coating. The fluid state allows the material to penetrate and conform to the microroughness and micro-porosity of the unclosed ceramic crock surface, ensuring complete wetting and intimate contact. After solidification, this creates strong mechanical interlocking and chemical bonding, overcoming the adherence problems associated with the rough ceramic surface while maintaining cooking capability.
4Reliability
If a fluid antiskid coating is deposited into a groove and solidified in situ, then the coating can provide good adherence, but it is difficult to control the quantity to avoid overflow and peeling lips
Solution Approach 1:
The patent applies the fluid antiskid material in excess, allowing it to overflow the groove boundaries. This excessive action ensures complete filling of the groove and coverage of the entire bearing surface. The key is that the material is applied in fluid state, allowing it to self-level and conform to the substrate, and then solidifies in place, capturing the excess material as part of the cohesive coating structure rather than creating peeling lips.
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 antiskid coating effectively prevents skidding while ensuring strong adherence to dinner plates, reducing the risk of peeling and maintaining the container's stability and aesthetic appeal.
Implementation Method 1
The cord is deposited in the form of a fluid elastomer composition, which is then caused to solidify by polymerization. The polymerization, more specifically vulcanization, allows for silicone to adhere to glass.
Implementation Method 2
The polymerization, more specifically vulcanization, allows for silicone to adhere to glass.
