Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If electric heating pipes are used for heating, then the structure is simple, but the preheating time is long and power consumption is high
Solution Approach 1:
The patent replaces the electric heating pipe system with an electromagnetic induction heating system. The induction heating element generates a magnetic field that directly induces eddy currents in the baking tray, heating it directly without the need for intermediate heating elements. This substitution of heating mechanism dramatically reduces preheating time and improves energy efficiency by eliminating the two-step heat transmission process.
Solution Approach 2:
The patent changes the heating method from resistive heating (electric heating pipes) to electromagnetic induction heating. This parameter change in the heating mechanism allows for direct heating of the baking tray through induced currents, significantly reducing the time and energy required to reach operating temperature.
2Ease of operation
If fixed baking trays are used, then the structure is stable, but cleaning is inconvenient and water can damage electronic components
Solution Approach 1:
The patent divides the grill toaster into separable components: the baking trays are made detachable from the main body. This segmentation allows users to easily remove the baking trays for cleaning without risking water damage to the electronic components housed in the main body, thus improving cleaning convenience while maintaining reliability.
Solution Approach 2:
The baking trays are extracted as separate, removable components from the main device body. This extraction design enables independent cleaning of the trays while keeping the main body protected from water, resolving the contradiction between cleaning ease and water damage prevention.
3Productivity
If electromagnetic induction heating is used, then preheating time is reduced, but the device complexity increases
Solution Approach 1:
The electromagnetic induction heating element serves multiple functions: it heats the baking tray rapidly for toasting, and can also be used for grilling at higher temperatures. This multi-functionality justifies the added complexity by providing superior performance across different cooking modes.
Solution Approach 2:
The patent changes the heating mechanism parameter from conventional resistive heating to electromagnetic induction heating. This parameter change enables faster heating speeds and higher temperature capabilities, improving productivity despite the increased device complexity.
4Productivity
If cooking temperature exceeds 250°C, then cooking efficiency improves, but baking trays become deformed
Solution Approach 1:
The baking trays are made from composite materials that combine high heat resistance with structural stability. These composite materials can withstand the higher temperatures achieved through electromagnetic induction heating without deforming, enabling improved cooking efficiency while maintaining tray integrity.
Solution Approach 2:
The patent changes the material parameter of the baking trays to use heat-resistant composite materials. This material parameter change allows the trays to withstand temperatures above 250°C without deformation, enabling higher cooking temperatures and improved cooking efficiency.
