Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the radio-frequency connector is connected to the side face of the semiconductor microwave generator, then the microwave transmission can be achieved, but the distance between the generator and cooking cavity becomes large, increasing the size of the microwave oven
Solution Approach 1:
The patent changes the connection orientation from side-face (horizontal dimension) to top-face (vertical dimension), allowing the microwave output device to extend downward directly into the cooking cavity, thereby reducing the horizontal distance and overall footprint of the microwave oven while maintaining transmission reliability
2Reliability
If the distance between the semiconductor microwave generator and the cooking cavity is large, then the microwave transmission path is established, but the transmission loss increases and heating efficiency decreases
Solution Approach 1:
The patent extracts the microwave output device from the traditional side-face connection and positions it to extend directly downward from the top face, shortening the transmission path and reducing the distance microwave signals must travel through air, thereby minimizing transmission loss and improving heating efficiency
3Reliability
If the distance between the semiconductor microwave generator and the cooking cavity is large, then the microwave transmission can be achieved, but the manufacturing costs increase
Solution Approach 1:
The patent repositions the microwave output device connection from the side face to the top face, allowing for a more compact overall design that reduces the required internal volume of the microwave oven, thereby lowering material costs and simplifying the manufacturing process
