Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed resistance temperature sensor is used, then the device complexity is reduced, but the measurement precision deteriorates for different cooking accessories
Solution Approach 1:
The patent applies parameter changes by varying the resistance value of the resistive element on the plug to correspond to different cooking accessory types. Each accessory type has a unique resistance value (e.g., 100 ohms for baking, 200 ohms for broiling) that is detected by the controller, allowing the system to adapt the temperature measurement parameters to match the specific accessory being used, thereby improving measurement precision without significantly increasing device complexity
2Adaptability or versatility
If a universal temperature sensor is used for all cooking accessories, then the adaptability is improved, but the measurement precision deteriorates due to variations in accessory physical properties
Solution Approach 1:
The patent applies local quality by assigning specific resistance values to specific cooking accessory types. Instead of using a single universal sensor configuration, the system identifies the local requirements of each accessory type (baking, broiling, heating, etc.) and configures the temperature measurement parameters locally for each accessory, thereby maintaining high measurement precision across different accessory types while preserving adaptability
3Measurement precision
If the resistive element value is changed for different accessories, then the measurement precision is improved, but the device complexity increases due to multiple resistive elements
Solution Approach 1:
The patent applies preliminary action by pre-configuring the resistive element values on the plugs before they are inserted into the oven. Each plug is manufactured with the correct resistance value already embedded, corresponding to its specific accessory type. This eliminates the need for the oven to have multiple configurable resistive elements or complex switching mechanisms, thereby improving measurement precision while keeping the oven's device complexity low
