Innovation Solution
A wireless food temperature monitoring system comprising a wireless probe with a circuit board, temperature sensor, super capacitor, and radio frequency transmitter, along with a mobile device and/or wireless range extender for receiving and processing temperature signals, eliminating the need for physical wiring and enabling remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal wire is used to connect the probe to the transmitter unit, then the electronic parts are kept away from heat, but the wire tangles with rotisserie and prevents the oven door from completely closing
Solution Approach 1:
The patent extracts the metal wire connection from the system by implementing a wireless communication module in the probe that transmits temperature data via radio frequency signals. This eliminates the physical wire that caused tangling and door closure issues, while the probe itself remains connected to the food through a heat-resistant stem that can penetrate the oven door seal.
Solution Approach 2:
The patent introduces a wireless communication module as an intermediary between the temperature sensor and the external display unit. This intermediary enables data transmission without physical wire connection, resolving the conflict between protecting electronics from heat and maintaining ease of oven operation.
2Loss of information
If a wireless food thermometer is developed with three parts (metal temperature sensor probe, transmitter unit, receiver/controller unit), then real-time monitoring is enabled, but wiring issues create troubles for the user
Solution Approach 1:
The patent merges the transmitter functionality directly into the probe assembly, eliminating the separate wire connection between probe and transmitter unit. The probe contains both the temperature sensor and wireless transmission capabilities, allowing real-time monitoring without the operational troubles of external wiring.
Solution Approach 2:
The patent replaces the mechanical wire connection system with an electromagnetic wireless communication system. The metal wire that physically connected the probe to the transmitter is substituted with radio frequency signal transmission, eliminating tangling and door closure problems while maintaining real-time temperature monitoring capability.
