Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for pairing a hob with cookware are cumbersome and prone to time delays, requiring multiple user actions and potentially allowing for remote operation, which can compromise safety.
Innovation Solution
A method using a hob and cookware with wireless transmitter/receiver units that establish pairing with a lower transmission power to ensure proximity, then switch to higher power for normal operation, preventing remote effects and enhancing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio transmission with high power is used for communication between cookware and hob, then data transmission range and reliability are improved, but remote operation becomes possible which compromises safety
Solution Approach 1:
The transmission power is dynamically adjusted based on the operational phase: during pairing mode, high transmission power is used to ensure reliable connection establishment, while during cooking operation, transmission power is reduced to minimal levels necessary for maintaining communication, thereby preventing remote operation while ensuring communication reliability when needed
Solution Approach 2:
The system changes the transmission power parameter between different operational states - using higher power during the pairing phase to overcome initial connection challenges, and switching to lower power during normal operation to limit communication range and prevent remote operation, thus resolving the safety concern while maintaining communication effectiveness
2Object-affected harmful factors
If multiple user actions are required for pairing hob with cookware, then remote operation is prevented, but the pairing process becomes cumbersome and time-consuming
Solution Approach 1:
The system enables self-service pairing by automatically detecting the presence of cookware on the hob and initiating the pairing process without requiring multiple user actions. The hob and cookware autonomously complete the pairing handshake, reducing user burden to a single placement action while maintaining security through controlled transmission power protocols
Solution Approach 2:
The system performs preliminary pairing actions automatically when cookware is placed on the hob, initiating the pairing sequence in advance before the user needs to cook. This preliminary automatic pairing reduces the number of subsequent user actions required, making the process easier while the controlled transmission power prevents remote operation
3Object-affected harmful factors
If transmission power is reduced during pairing to ensure proximity, then remote operation is prevented, but data transmission capability during normal operation is limited
Solution Approach 1:
The transmission power is dynamically adjusted based on the operational phase: during pairing mode, high transmission power is used to ensure reliable connection establishment, while during cooking operation, transmission power is reduced to minimal levels necessary for maintaining communication, thereby preventing remote operation while ensuring communication reliability when needed
Solution Approach 2:
The system uses periodic transmission bursts rather than continuous high-power transmission during normal operation. Data is transmitted in periodic intervals at low power levels, which is sufficient for maintaining communication between the hob and cookware while minimizing the risk of remote operation and reducing energy consumption
