Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature measuring devices for cooking applications have limited operating times due to high energy consumption, as they transmit temperature information frequently regardless of the cooking process, leading to inefficient energy use.
Innovation Solution
A method where the temperature measuring device adjusts the transmission times of temperature information based on the temperature difference between the actual and setpoint values, allowing for adaptive energy input and reducing unnecessary data transmission during stable cooking phases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the temperature measuring device transmits temperature information frequently at fixed intervals, then the temperature control precision is improved, but the energy consumption increases
Solution Approach 1:
The transmission interval is made dynamic rather than fixed. The device adjusts the transmission interval based on the absolute temperature difference between actual and setpoint values. When the temperature difference is large, transmissions occur more frequently; when the temperature difference is small, transmissions occur less frequently. This dynamic adjustment resolves the contradiction by adapting the measurement precision to the actual cooking needs while optimizing energy consumption.
Solution Approach 2:
The transmission parameter (transmission interval) is changed based on temperature conditions. The system uses different transmission intervals depending on the temperature difference magnitude, changing from frequent transmissions during large temperature deviations to infrequent transmissions during stable temperature periods. This parameter change strategy allows the system to maintain adequate temperature control precision while significantly reducing overall energy consumption.
2Loss of information
If the temperature measuring device transmits temperature information at fixed intervals, then the data availability is improved, but the operating time on battery power decreases
Solution Approach 1:
The transmission schedule is made dynamic based on cooking phase detection. During active cooking phases with large temperature differences, the system transmits data frequently to ensure data availability. During stable cooking phases with small temperature differences, the system reduces transmission frequency, thereby extending battery operating time while maintaining adequate data availability when it matters most.
Solution Approach 2:
The system uses periodic transmissions with variable periods. Instead of fixed-interval periodic transmissions, the period is adjusted based on the cooking state. When the temperature difference exceeds a threshold, short periods are used; when the temperature difference is within the threshold, long periods are used. This variable periodic action resolves the contradiction between data availability and battery life extension.
3Manufacturing precision
If the transmission interval is reduced for better temperature control, then the temperature regulation accuracy is improved, but the energy input to the measuring device increases
Solution Approach 1:
The transmission interval parameter is changed dynamically based on temperature regulation needs. When temperature regulation accuracy requirements are high (large temperature difference), the system uses short transmission intervals. When temperature stability is achieved (small temperature difference), the system switches to long transmission intervals. This parameter adaptation resolves the contradiction by matching energy input to actual regulation accuracy requirements.
