Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If gas heating is used in the grilling device, then heating speed is improved, but temperature control becomes difficult
Solution Approach 1:
A mechanical temperature controller is introduced as an intermediary device between the gas heating source and the pan. This controller includes a double-metal piece mechanism that responds to temperature changes and automatically regulates the heating, providing both fast heating capability and precise temperature control without requiring complex electronic systems.
2Productivity
If double-layer pan structure is used, then cooking capacity is improved, but pan stability deteriorates due to food expansion
Solution Approach 1:
The pan handle connection mechanism is designed to be dynamically adjustable. The connection allows the pan to accommodate expansion forces from cooking food while maintaining stable positioning. The mechanical temperature controller and handle locking mechanism work together to provide stability during the cooking process, preventing the pan from opening due to food expansion while preserving the double-layer cooking capacity.
3Adaptability or versatility
If mechanical temperature controller is added, then temperature adjustability is improved, but device complexity increases
Solution Approach 1:
The mechanical temperature controller utilizes parameter changes in the double-metal piece mechanism, which expands or contracts in response to temperature variations. By rotating the bronze axle, the user adjusts the preset temperature parameter, and the mechanical system automatically maintains this temperature through thermal expansion and contraction of the bimetallic strip, providing temperature control without electronic complexity.
4Reliability
If handle locking mechanism is implemented, then pan security is improved, but operation convenience may worsen
Solution Approach 1:
The handle locking mechanism is designed to be self-regulating through the mechanical temperature controller system. As the pan reaches the preset temperature, the double-metal piece mechanism automatically triggers the locking action, securing the handle without requiring additional user intervention. This self-service approach maintains pan security while minimizing impact on operational convenience.
