Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In larger rooms with multiple radiators, existing thermostatic radiator valve (TRV) controllers require multiple thermostats for effective temperature regulation, leading to increased costs and complex system setups, and synchronizing control across multiple TRV controllers is challenging due to mechanical and material tolerances.
Innovation Solution

Engineering Contradiction Analysis
1Area of stationary object
If multiple thermostats are used to control multiple TRV controllers in larger rooms, then temperature regulation coverage is improved, but system cost and complexity increase
Solution Approach 1:
A single thermostat is designed to control multiple TRV controllers simultaneously, making the thermostat multi-functional. The thermostat communicates with multiple radiators through wireless channels, eliminating the need for separate thermostats for each radiator and reducing overall system complexity while maintaining large room coverage
Solution Approach 2:
Multiple TRV controllers are merged into a single controlled system through one thermostat. The thermostat aggregates control functions for multiple radiators, combining what would traditionally require separate thermostat units into a unified control system that reduces component count and simplifies installation
2Area of stationary object
If multiple thermostats are used to control multiple TRV controllers in larger rooms, then temperature regulation coverage is improved, but system cost increases
Solution Approach 1:
The thermostat is designed with multi-functionality to control multiple TRV controllers simultaneously, reducing the quantity of thermostats needed from one per radiator to a single unit that manages all radiators through wireless communication
Solution Approach 2:
The control functions for multiple radiators are merged into a single thermostat unit, consolidating what would traditionally require multiple separate thermostat devices into one cost-effective solution that covers larger areas
3Manufacturing precision
If auto-detection of pin positions is implemented, then manufacturing precision requirements are reduced, but measurement and detection complexity increases
Solution Approach 1:
The TRV controller performs self-calibration by automatically detecting the minimum and maximum pin positions through sensor feedback during operation. The system uses the radiator temperature sensor to detect heat transfer patterns and autonomously determines the correct pin position range without requiring manual adjustment or high manufacturing precision
Solution Approach 2:
The system implements feedback through temperature sensors that monitor radiator heat transfer and provide information to the TRV controller. This feedback loop enables the controller to detect pin positions automatically by analyzing temperature patterns, compensating for manufacturing tolerances through intelligent measurement rather than precision manufacturing

AI summary
A heating system includes a single thermostat that controls multiple thermostatic radiator valve (TRV) controllers that control heat transfer to radiators in a room. Each TRV controller has the capability to automatically detect the open/closing point and maximum heating point and to register corresponding pin positions of the valve. Each TRV controller is subsequently instructed by the thermostat to adjust the valve in relation to a determined percentage of the registered pin positions, thus accounting for the varying characteristics among the valves in the system. The TRV controller detects the maximum heating point by checking the rate of temperature rising and the open/closing point by sensing the temperature turning point through a temperature sensor situated appropriately in relation to the associated radiator.
