Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the air guide is designed to cool heat generation elements, then cooling efficiency is improved, but heated air may leak into the electric range causing overheating of components
Solution Approach 1:
The air guide is divided into a first air guide portion and a second air guide portion with different functions. The first portion guides air horizontally to cool heat generation elements, while the second portion redirects air vertically outward, preventing heated air leakage into the electric range interior.
Solution Approach 2:
The expansion protrusion acts as an intermediary sealing structure between the air guide and base bracket. It fills gaps and creates a sealed connection that prevents heated air from leaking through the coupling interface while maintaining the airflow path for cooling.
2Reliability
If the air guide and base bracket are coupled to prevent leakage, then heated air leakage is suppressed, but the coupling structure becomes more complex
Solution Approach 1:
The expansion protrusion is integrated directly into the air guide structure, merging the sealing function with the air guiding function. This eliminates the need for separate sealing components while achieving both leakage prevention and simplified coupling.
Solution Approach 2:
The expansion protrusion automatically seals the gap between the air guide and base bracket through its own geometric shape and elastic deformation, without requiring additional sealing materials or complex fastening mechanisms. The structure self-adjusts to create a tight seal.
3Ease of manufacture
If the air guide structure is simplified for easy manufacturing, then ease of manufacture is improved, but sealing performance may deteriorate
Solution Approach 1:
The expansion protrusion utilizes geometric parameter changes (expansion in cross-sectional area) to achieve sealing. This approach uses simple dimensional variations rather than complex materials or multi-step manufacturing processes, maintaining ease of manufacture while ensuring reliable sealing.
