Glass Dish Silicone Support for Heat-Resistant Non-Slip Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Glassware tends to slide on smooth surfaces, causing damage and potential spillage, and existing non-slip solutions like rubber rings are unsuitable for high-temperature environments, while silicone coatings on glassware are costly and prone to peeling.
Innovation Solution
A glass dish with a silicone support integrated into a channel on its bottom surface, where the silicone is chemically adhered to the glass and protrudes beyond the channel's edge, providing a non-slip surface without intermediate adhesives and resistant to high temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If india rubber ring is placed in recess on bottom of hollow ware, then non-slip barrier is formed, but deformation and melting occur at high temperatures
Solution Approach 1:
The patent changes the material parameter from india rubber to silicone elastomer, which has a higher temperature tolerance threshold. Silicone maintains its physical properties at high temperatures where india rubber would deform or melt, while preserving the non-slip barrier function through the same recess configuration.
Solution Approach 2:
The invention creates a composite structure by integrating silicone elastomer material with glass hollow ware. The silicone is molded directly into the recess of the glass body, forming a durable composite assembly where the silicone provides heat resistance and non-slip properties while the glass provides structural integrity.
2Ease of operation
If silicone coating is applied to glassware surface, then non-slip surface is provided, but peeling occurs under shear forces
Solution Approach 1:
The patent segments the silicone elastomer into a discrete component that is molded within a recess rather than applied as a surface coating. This segmentation allows the silicone to be mechanically integrated into the glass structure, where the recess walls provide physical constraints that prevent peeling under shear forces.
Solution Approach 2:
The recess is designed with curved surfaces that conform to the silicone elastomer, creating a snug fit that maximizes contact area and mechanical interlocking. The curved geometry of the recess prevents the silicone from peeling away from the glass surface under applied forces.
3Ease of operation
If silicone is applied using traditional dipping or spraying techniques, then protective surface is formed, but high material cost and extensive application required
Solution Approach 1:
The patent extracts the silicone application to only the necessary area - the recess on the bottom surface - rather than applying silicone to the entire glassware surface. This targeted approach reduces material consumption and manufacturing complexity while maintaining the non-slip function where it is most needed.
Solution Approach 2:
Instead of applying silicone uniformly across the entire surface (excessive action), the invention applies silicone only to the recess area (partial action), which is sufficient to provide the non-slip characteristic. This partial application reduces both material cost and manufacturing time while achieving the desired functional outcome.
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 effectively prevents sliding and damage by providing a durable, heat-resistant non-slip surface that adheres directly to the glass without additional bonding agents, ensuring stability and safety in both low and high-temperature applications.
Implementation Method 1
That portion of the silicone support that contacts the inner surface of the channel is adhered to the inner surface of the channel by chemical adhesion
Implementation Method 2
Silicone generally exhibits good non-slip characteristics

AI summary
A glass dish suitable for use in cooking applications is provided. The glass dish comprises a substantially homogenous glass body, a channel formed in a bottom surface of the glass body and a silicone support. The channel has an open end and an inner surface comprised of a substantially planar bottom wall, an inner sidewall and an outer sidewall. The channel has a predetermined depth Do, and an open end of the channel has a predetermined width Wo. The silicone support is comprised of a protruding extent and an interior extent. The interior extent is disposed within the channel and directly contacts a portion of the inner surface and is adhered to the inner surface of the channel by chemical adhesion. The protruding extent protrudes beyond the open end of the channel.
