Solution Overview
Problem
Existing pan handles face issues with excessive heating, complex and costly assembly, and durability problems due to insufficient thermal insulation and high material costs, particularly with steel, wood-coated, and silicone-based solutions.
Innovation Solution
A pan handle design featuring a thin sheet metal core enclosed by heat-resistant reinforcement half-bodies made of inexpensive materials, coated with a clear and transparent silicone resin sheath for improved thermal resistance and aesthetic appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a steel tube handle is used, then the handle provides structural support, but it becomes excessively heated during cooking
Solution Approach 1:
The handle combines a steel tube core for structural strength with a synthetic resin coating for thermal insulation. This composite structure allows the metal core to provide mechanical support while the resin layer prevents excessive heating, resolving the contradiction between strength and temperature resistance.
2Temperature
If thermally insulating means are added between the pan body and handle, then handle heating is reduced, but assembly becomes more complex and expensive
Solution Approach 1:
The thermal insulation function is merged with the handle's outer coating by applying a synthetic resin layer directly onto the metal core. This integration eliminates the need for separate insulating components and simplifies assembly, while still providing effective thermal protection.
Solution Approach 2:
The handle uses a composite structure where the synthetic resin coating serves dual purposes: thermal insulation and structural completion. This eliminates the need for additional insulating means, reducing assembly complexity while maintaining temperature protection.
3Temperature
If wood coating is applied to the metal core, then thermal insulation is provided, but the coating deteriorates with continued use
Solution Approach 1:
The patent changes the material parameter from organic wood to synthetic thermosetting resin, which has superior resistance to heat, moisture, and mechanical degradation. This material substitution maintains thermal insulation properties while dramatically improving coating durability and resistance to deterioration from washing and cooking operations.
4Reliability
If the metal core is coated with synthetic material using overmolding method, then a complete synthetic handle is formed, but the process is slow, expensive and complex
Solution Approach 1:
Instead of completely overmolding the entire handle, the patent applies the synthetic resin coating only to the necessary outer surface layer. This partial coating approach achieves the required thermal insulation and aesthetic completion while significantly reducing processing time and cost compared to full overmolding.
5Temperature
If silicone resin is used for the entire handle, then thermal resistance and aesthetics are improved, but the cost becomes very high
Solution Approach 1:
The patent applies the expensive silicone resin coating only to the outer surface layer where thermal insulation and aesthetics are needed, while the structural core remains as a cheaper metal. This localized application provides the required thermal resistance and aesthetic quality without incurring the high cost of completely silicone-based handles.
