Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable griddles face manufacturing complexity and cleaning difficulties due to the mechanical joining of roasting plates and metal containers, which complicates assembly and maintenance.
Innovation Solution
A portable griddle design that superimposes a glass-ceramic plate and metal container around the perimeter using an adhesive component, allowing air circulation between the electric elements and container, with a sauce-collector tray for automatic sauce evacuation and redistribution without auxiliary utensils.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical joining methods are used to connect the roasting plate and metal container, then structural strength is improved, but manufacturing complexity and cleaning difficulty increase
Solution Approach 1:
The patent replaces mechanical joining methods (screws, clips, or interlocking mechanisms) with a thermal field-based adhesive bonding system. The adhesive component is activated by heat from the electric heating element, transforming the connection method from mechanical to thermal-chemical bonding. This substitution simplifies the assembly structure while maintaining structural integrity, directly resolving the contradiction between strength and manufacturing complexity.
2Strength
If mechanical joining methods are used to connect the roasting plate and metal container, then structural strength is improved, but cleaning ease deteriorates
Solution Approach 1:
By replacing mechanical fasteners with adhesive bonding activated by thermal field, the patent eliminates protruding joints, screw holes, and interlocking surfaces that trap food particles and grease. The smooth, continuous bonding interface created by the adhesive component allows for easier wiping and cleaning, directly addressing the cleaning ease deterioration caused by mechanical joining methods.
3Power
If electric elements are placed in direct contact with the metal container, then heating efficiency is improved, but heat distribution uniformity deteriorates
Solution Approach 1:
The patent introduces air as an intermediary medium between the electric heating element and the metal container. This air gap acts as a thermal mediator that distributes heat more uniformly across the container surface, preventing localized hot spots while maintaining overall heating efficiency. The air circulation also allows for even heat distribution around the entire container perimeter.
4Stability of the object's composition
If the roasting plate and container are joined together, then structural stability is improved, but component separability for maintenance deteriorates
Solution Approach 1:
The patent creates a dynamic bonding system where the adhesive component transitions from a flexible state during assembly to a rigid state after thermal activation. During the heating phase, the adhesive provides strong structural stability. For maintenance, the entire assembly can be disassembled by reversing the thermal activation process or applying mechanical force to the adhesive-bonded interfaces, enabling component separation when needed.
