Solution Overview

Problem

Current thermal management systems in buildings often result in suboptimal temperature regulation due to the configuration of heat emitters and thermostats, leading to inefficient heating distribution and energy wastage, as the system may shut down heating in one room even if other rooms have not reached their temperature setpoints.

Innovation Solution

A thermostatic radiator valve (TRV) system with communication links to a processing unit, allowing for dynamic aperture settings based on temperature configuration models, enabling each room to maintain its setpoint temperature while optimizing energy use by adjusting the flow of heating fluid across multiple rooms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a thermostat controls the thermal energy generator based on a single room's temperature, then the control system is simple, but the temperature setpoints in other rooms cannot be reached

Engineering Contradiction:
Improvetemperature setpoint achievementVSAvoidcontrol system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the building into multiple thermal zones, each with its own temperature setpoint requirements. The processing unit divides the control task by receiving temperature setpoints from multiple thermostats located in different rooms, allowing independent temperature control for each zone while coordinating through centralized processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The processing unit acts as an intermediary between multiple thermostats and the thermal energy generator. It receives temperature setpoints from various room thermostats, processes this information through a temperature configuration model, and determines the appropriate control signals for the thermal energy generator, thereby coordinating multiple temperature requirements without direct complex interconnections.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If the thermal energy generator shuts down when one room reaches its temperature setpoint, then energy consumption is reduced, but other rooms may not reach their temperature setpoints

Engineering Contradiction:
Improveenergy consumptionVSAvoidtemperature setpoint achievement
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The system implements comprehensive feedback by continuously monitoring temperature setpoints from multiple thermostats and room temperature conditions. The processing unit uses this feedback information to determine when the thermal energy generator should shut down, ensuring that shutdown decisions are based on the thermal status of all rooms, not just one, thereby preventing premature shutdown while optimizing energy consumption.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The temperature configuration model performs preliminary analysis of the thermal requirements for all rooms before controlling the thermal energy generator. By pre-processing the temperature setpoints and thermal relationships, the system can predict when shutdown is safe to occur, ensuring all rooms will reach their setpoints before the generator stops operating.

3Ease of manufacture

If traditional thermostatic valves are used without communication links, then the system is simple to implement, but suboptimal thermal regulation occurs due to lack of coordination between rooms

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The processing unit serves multiple functions: it acts as a communication hub for thermostat data, a processor for temperature configuration modeling, and a control signal generator for the thermal energy generator. This multi-functional approach consolidates what would otherwise require separate systems, maintaining implementation simplicity while achieving coordinated thermal regulation across multiple rooms.
