Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing processes for barbecue grill frying pans, such as iron plate oil-baking, sanding and oiling, and enameling, result in products with poor texture, low resistance to wear and moisture, and safety concerns due to heavy metal content in enameling processes.
Innovation Solution
A process involving selecting a cold-rolled or hot-rolled plate, cutting and forming, welding, grinding, sanding with brown fused alumina, cleaning, baking, applying a ceramic paint, and curing to produce a frying pan with improved texture, scratch resistance, and safety without heavy metals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If iron plate oil-baking process is used, then the frying pan surface is treated with oil, but the surface becomes contaminated with dirt, has flow marks, and takes on uneven oily yellow color resulting in poor texture
Solution Approach 1:
The invention extracts and removes the harmful oil treatment step from the manufacturing process. Instead of applying oil to the iron plate surface, the process uses sanding and blasting to create a clean, textured surface that achieves non-stick properties without oil contamination, thereby eliminating flow marks and uneven coloring while maintaining manufacturing simplicity
Solution Approach 2:
The invention changes the surface treatment parameters from chemical (oil application) to physical (sanding and blasting). By controlling the sanding grain size and blasting parameters, the process achieves uniform surface texture with improved adhesion properties, eliminating the visual defects associated with oil-baking while maintaining process efficiency
2Manufacturing precision
If iron plate sanding and oiling process is used, then the surface keeps tiny particle texture and silver metal texture, but resistance to wear and scratch is low and moisture protection is insufficient
Solution Approach 1:
The invention creates a composite surface structure by combining the iron plate base material with a sand-blasted oxide layer. This composite surface structure provides enhanced wear resistance, scratch resistance, and moisture protection while maintaining the desired tiny particle texture and silver metal appearance
Solution Approach 2:
The invention performs preliminary surface preparation through sanding and blasting before final assembly and packaging. This preliminary action creates a surface that is pre-treated with enhanced protective properties, eliminating the need for post-use oiling and providing immediate wear and moisture resistance
3Reliability
If iron plate enameling process is used, then moisture-proof and rustproof performance is improved, but the process is complicated with frequent enamel bursting, low shock resistance, high scrap ratio and high cost
Solution Approach 1:
The invention replaces the complex, expensive enameling process with a simpler, more cost-effective surface treatment using sanding and blasting. While the enamel coating provides good protection, it is fragile and expensive to apply; the invention uses a more durable, cost-effective mechanical surface treatment that achieves comparable or superior protection without the complexity and high scrap rates associated with enameling
Solution Approach 2:
The invention replaces the chemical enameling process with a mechanical surface treatment process. Instead of applying and curing enamel coatings through complex thermal and chemical processes, the invention uses mechanical sanding and blasting to create a protective surface layer, thereby simplifying the production process and reducing equipment requirements
4Reliability
If iron plate enameling process is used, then moisture-proof performance is improved, but paint contains heavy metal which is neither sanitary nor safe
Solution Approach 1:
The invention extracts and removes the harmful enamel coating containing heavy metals from the frying pan manufacturing process. By using sanding and blasting to create a protective surface layer, the process eliminates the need for paint or enamel applications, thereby removing heavy metal contamination risks and improving sanitary safety while maintaining moisture-proof performance
