Temperature prompting method and device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature monitoring and control systems for heating water lack flexibility and accuracy in prompting users when the water reaches a desired temperature, as they typically rely on fixed timing or temperature thresholds, failing to account for user movement and container distance.
Innovation Solution
A method and device that acquire the current temperature and distance of a target container to a linked terminal, calculate the time duration for the water to reach a target temperature and the user to reach the container, and trigger a prompt signal if the water reaches the target temperature before the user, ensuring timely notification and efficient heating control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fixed timing or temperature thresholds are used for prompting, then the control system is simple, but the prompting accuracy and flexibility deteriorate
Solution Approach 1:
The patent transforms the static fixed threshold prompting into a dynamic prompting mechanism that adapts to real-time conditions. The system continuously monitors user position and container position, dynamically calculating the time required for the user to reach the container, and adjusts the prompting temperature threshold accordingly. This allows the water to be prompted at the optimal temperature rather than a fixed threshold, resolving the contradiction between system simplicity and prompting accuracy.
Solution Approach 2:
The system performs preliminary calculations of the user's travel time to the container before the water reaches the boiling point. By predicting when the user will arrive and working backward to determine the optimal prompting temperature, the system prepares the prompting strategy in advance. This preliminary action enables more accurate timing without requiring complex real-time decision-making, balancing simplicity and accuracy.
2Device complexity
If the water is heated to a fixed temperature threshold, then the heating control is simple, but the user experience deteriorates due to timing mismatch
Solution Approach 1:
The system implements a feedback loop that continuously monitors user position, container position, and water temperature. Based on this feedback, the system dynamically adjusts the prompting temperature threshold to ensure the water is ready exactly when the user arrives. This feedback mechanism maintains relatively simple heating control while dramatically improving user experience by eliminating the timing mismatch between water readiness and user arrival.
3Use of energy by stationary object
If the prompting temperature threshold is lowered, then the energy consumption is reduced, but the water may not be hot enough for the user's needs
Solution Approach 1:
The system dynamically changes the temperature parameter based on real-time conditions rather than using a fixed threshold. By calculating the user's arrival time and determining the optimal prompting temperature, the system ensures the water reaches sufficient temperature for user needs while avoiding unnecessary energy consumption from overheating. This parameter adaptation resolves the contradiction between energy efficiency and temperature sufficiency.
