Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a heating member is arranged outside and below a baking tray to radiate heat by reflection, then the heating and cooking function is achieved, but the heat cannot be fully radiated to the baking tray, leading to insufficient heat utilization and energy loss
Solution Approach 1:
The infrared wave-transmitting separator features a non-coplanar first side surface with curved or inclined portions that refract infrared rays from the heating member toward the baking tray, directing heat energy more effectively to the cooking surface and reducing lateral heat loss
Solution Approach 2:
An infrared wave-transmitting separator is introduced as an intermediary component between the heating member and the baking tray. This separator refracts infrared rays to improve heat radiation directionality, ensuring more complete heat utilization while maintaining the functional relationship between the heating member and baking tray
2Loss of energy
If an infrared wave-transmitting separator with non-coplanar surfaces is introduced to refract infrared rays, then energy utilization is improved, but the device complexity increases
Solution Approach 1:
The non-coplanar first side surface of the infrared wave-transmitting separator uses curved or inclined geometric features to refract infrared rays. This curvature-based design achieves effective heat direction control while maintaining a relatively simple single-piece structure that can be manufactured as one component
Solution Approach 2:
The infrared wave-transmitting separator is made from materials with specific infrared transmission properties, and its surface geometry parameters (inclination angles, curvature radii) are optimized to achieve effective infrared ray refraction. These parameter optimizations enable improved heat utilization with minimal structural complexity
