Water Heater Controller Parameter Lock for Remote Safety Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water heating systems lack effective control mechanisms to prevent undesirable temperature changes in water tanks, leading to suboptimal or unsafe water temperatures for various applications, and there is a need for a system that can regulate and notify users of attempts to set temperatures outside safe bounds.
Innovation Solution
A controller system that communicates with user devices to enable or disable the ability to change the set point temperature of a water tank, generating notifications for irregular temperature changes and maintaining or reverting to safe temperature ranges, using processing circuitry to manage the main burner's operation and ensure water temperatures remain within a comfortable and safe range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the controller allows free adjustment of set point temperature, then user flexibility and adaptability are improved, but temperature safety and reliability deteriorate due to potential setting of unsafe temperatures
Solution Approach 1:
The controller dynamically changes its operational state based on detected conditions. When an unsafe temperature adjustment is detected, the controller transitions from an enabled state (allowing temperature changes) to a disabled state (preventing further changes), making the control parameter adaptive rather than static
Solution Approach 2:
The system implements feedback by detecting when a user attempts to set an unsafe temperature, then responding by disabling further adjustments. This closed-loop feedback mechanism ensures safety while initially allowing flexibility, resolving the contradiction between user adaptability and temperature reliability
2Reliability
If the controller disables the ability to change set point temperature, then temperature safety and reliability are improved, but user flexibility and adaptability worsen
Solution Approach 1:
The controller employs dynamic control where the ability to adjust temperature is not permanently disabled but conditionally restricted. The system transitions between enabled and disabled states based on safety conditions, maintaining user flexibility when safe while ensuring reliability when necessary
Solution Approach 2:
The controller takes preliminary anti-action by preventing unsafe temperature adjustments before they can cause harm. By detecting potential unsafe settings in advance and disabling adjustments proactively, the system protects against future safety issues while preserving user flexibility for safe adjustments
3Loss of information
If the system notifies users of irregular temperature changes, then information completeness and user awareness are improved, but system complexity and loss of time worsen due to additional communication overhead
Solution Approach 1:
The notification system implements feedback by informing users when unsafe temperature adjustments are detected and when the controller transitions to a disabled state. This feedback loop maintains user awareness without requiring complex continuous communication, balancing information completeness with system simplicity

Function Achieved in This Case
The system effectively prevents undesirable temperature changes by locking or enabling the ability to adjust the set point temperature based on user input, ensuring water temperatures remain within safe bounds, thus providing comfortable and safe hot water for applications like showers and washing machines.
Implementation Method 1
Some systems use a pilot light which ignites a main burner configured to heat water within the water tank

AI summary
This disclosure is related to devices, systems, and techniques for controlling a temperature of water contained by a water tank. A controller includes a user interface configured to receive one or more user inputs indicative of a request to set a control parameter of the controller and communication circuitry configured to receive, from a user device, an electronic signal. Additionally, the controller includes processing circuitry configured to identify, from the electronic signal, one or more first data packets that include a request to disable an ability to change, based on the one or more user inputs received by the user interface, the control parameter of the controller and in response to receiving the one or more first data packets, disable the ability to change the control parameter of the controller.
