Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic products, such as electrically heated molten incense burners and candle incense burners, face the issue of molten wax becoming firmly attached to the surface, making it difficult to withdraw and replace.
Innovation Solution
A glaze composition comprising potassium feldspar, lithium feldspar, calcium carbonate, talc, kaolin, wollastonite, quartz, alumina, and nanopowder, along with a specific preparation process involving mixing, grinding, and high-temperature firing, is used to create a ceramic surface resistant to wax block bonding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional glaze is used on ceramic surfaces, then the ceramic provides good aesthetics and basic functionality, but molten wax becomes firmly attached to the surface making removal difficult
Solution Approach 1:
The patent modifies the chemical composition parameters of the glaze by incorporating specific ratios of zinc oxide (10-20 parts), borax (5-15 parts), and other materials to create a surface with altered surface energy characteristics that prevent wax adhesion while maintaining aesthetic properties
Solution Approach 2:
The patent creates a composite glaze system combining multiple materials including zinc oxide, borax, feldspar, quartz, and coloring oxides that work together to produce a surface with both aesthetic appeal and anti-adhesion properties through synergistic interactions between components
2Reliability
If conventional glaze composition is used, then material costs and processing are straightforward, but the ceramic surface cannot resist wax block bonding
Solution Approach 1:
The patent performs preliminary grinding and mixing of all glaze components together in specific ratios before application, creating a pre-formulated composite slurry that ensures proper chemical interactions during firing while simplifying the manufacturing process through advance preparation
Solution Approach 2:
The patent optimizes firing temperature parameters (1230-1250°C for 11-14 hours) to achieve the desired glaze properties and wax resistance without requiring excessively complex multi-stage firing processes, balancing reliability with manufacturing simplicity
3Ease of operation
If existing glaze formulations are used, then production is simple and cost-effective, but molten wax adheres firmly requiring hot water for removal
Solution Approach 1:
The patent converts the typically harmful adhesive property of the glaze surface into a beneficial non-stick characteristic by adjusting the chemical composition to create a surface that actively repels wax, transforming what would be a cleaning problem into an easy-wipe surface
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 resulting ceramic surface effectively prevents wax from adhering, allowing for easy removal of hardened molten wax without the need for hot water, enhancing user convenience.
Implementation Method 1
a glaze surface layer resistant to wax block bonding is formed on the surface of the ceramic
Implementation Method 2
firing at a high temperature of 1230 - 1250°C for 11 - 14 h
