Solution Overview
Problem
Existing cooking systems lack efficient air circulation and temperature control mechanisms, particularly in countertop air grilling systems, which affect the cooking modes and food quality.
Innovation Solution
A cooking system with a housing having a hollow interior, a heating element, and a support body with diffuser ribs that deflect downward flowing fluid horizontally, combined with temperature sensors for monitoring and adjusting heat, ensuring optimal cooking conditions for various modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a support body with diffuser ribs is used to deflect downward flowing fluid horizontally, then air circulation efficiency is improved, but device complexity increases
Solution Approach 1:
The support body is segmented into multiple diffuser ribs that are distributed across its surface. Each rib acts as an independent flow deflection element, collectively achieving efficient air circulation while maintaining a relatively simple overall structure. The ribs divide the airflow into multiple streams, enhancing circulation effectiveness without requiring a completely complex support body design.
2Measurement precision
If multiple temperature sensors are used for monitoring and adjusting heat, then temperature control precision is improved, but device complexity increases
Solution Approach 1:
Temperature sensors are strategically positioned at specific locations within the cooking chamber where temperature variations are most critical. This localized sensing approach provides precise temperature control data for key zones without requiring sensors throughout the entire system, thereby maintaining measurement precision while limiting the increase in device complexity.
3Stability of the object's composition
If diffuser ribs are designed to reduce rotation of downward flowing fluid, then cooking uniformity is improved, but manufacturing precision requirements increase
Solution Approach 1:
The diffuser ribs are designed with asymmetric geometries that are optimized to counteract the natural rotational tendency of downward flowing fluid. The varying angles and profiles of the ribs create a balanced flow pattern that reduces rotation and promotes uniform cooking. This asymmetric design achieves cooking uniformity through functional optimization rather than requiring extremely precise symmetric manufacturing.
