Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control is used for cooking appliances, then ease of operation is improved, but safety deteriorates due to fire hazard from open heat sources
Solution Approach 1:
The patent replaces traditional mechanical remote control systems with NFC (Near Field Communication) technology. The control unit uses NFC transceivers to communicate with the cooking appliance only when placed in direct contact or very close proximity to the appliance surface, eliminating the safety risk of operating hot appliances from a distance while maintaining ease of operation through contactless NFC activation.
Solution Approach 2:
The patent introduces an NFC transceiver as an intermediary between the user and the cooking appliance. This intermediary enables control only when the control unit is physically near the appliance, creating a safety mechanism that prevents remote operation of open heat sources while still providing convenient control functionality.
2Reliability
If control units are fixed to the appliance, then reliability is improved, but adaptability deteriorates due to limited positioning options
Solution Approach 1:
The patent replaces fixed mechanical mounting systems with NFC-based wireless communication. Multiple NFC transceivers are distributed across the appliance surface, allowing the control unit to be reliably connected at various positions without physical attachment, thus providing both reliability through consistent NFC connectivity and adaptability through flexible positioning options.
Solution Approach 2:
The patent implements a universal control system where the control unit can operate the appliance from multiple positions on the surface. The multiple NFC transceivers enable the same control unit to function reliably regardless of where it is placed on the appliance, providing universal operability across different positions.
3Ease of operation
If NFC transmission units are arranged next to or below the mounting surface, then ease of operation is improved through flexible positioning, but device complexity increases
Solution Approach 1:
The patent divides the NFC communication system into multiple separate transceiver units distributed across the appliance surface. Each transceiver is a独立 component that can independently communicate with the control unit, allowing flexible positioning while managing complexity through modular, standardized units rather than a single complex system.
