Solution Overview

Problem

Existing heating systems for buildings are imprecise in regulating temperature across multiple rooms due to sensors detecting proximal temperatures near radiators, leading to inefficient energy use and premature wear, as they are influenced by radiator temperatures rather than actual room conditions.

Innovation Solution

A method and apparatus that calculate a corrective value by correlating ambient and proximal temperature measurements, allowing for precise temperature regulation across multiple rooms through a central data transmission system, enabling each heat-regulating device to adjust its operation based on accurate ambient temperature measurements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sensors are mounted in actuators near radiators to detect temperature, then the temperature detection is simple and direct, but the detected temperature is proximal to the radiator rather than the actual room temperature, leading to imprecise regulation

Engineering Contradiction:
Improvetemperature detection simplicityVSAvoidroom temperature measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The temperature sensing function is extracted from the actuator and relocated to a dedicated thermostat unit positioned in the room. This separation allows the sensor to measure actual room temperature rather than proximal temperature near the radiator, resolving the measurement precision issue while maintaining operational simplicity through centralized control.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A wireless communication system acts as an intermediary between the thermostat (sensing unit) and the actuator (control unit). The thermostat measures room temperature and transmits data wirelessly to the actuator, which then adjusts the heating element. This intermediary approach enables accurate remote sensing while maintaining simple local actuation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If heat-regulating devices use proximal temperature sensors near radiators, then the device structure is simple, but the temperature regulation becomes imprecise and intermittent, causing premature wear

Engineering Contradiction:
Improveheat-regulating device structureVSAvoidtemperature regulation stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system implements a feedback loop where the thermostat continuously monitors room temperature and wirelessly communicates with the actuator to adjust heating output. This closed-loop feedback ensures stable and precise temperature regulation, preventing the intermittent operation that causes premature wear, while the wireless communication maintains device structural simplicity.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The heating control system is segmented into two independent functional units: a thermostat for temperature sensing and a wireless actuator for control execution. This segmentation allows the sensing function to be optimally positioned in the room for accurate measurement, while the actuator remains simple and localized at the heating element, improving overall reliability without increasing complexity.

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If multiple rooms are regulated independently with individual sensors, then each room achieves precise temperature control, but the system complexity and cost increase significantly

Engineering Contradiction:
Improveper-room temperature control accuracyVSAvoidmulti-room system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The thermostat unit is designed as a universal multi-functional device that can serve multiple rooms. It integrates temperature sensing, processing, and wireless communication capabilities to control multiple actuators across different rooms. This universality enables precise temperature control in each room while avoiding the complexity of having separate dedicated systems for each room.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system merges the sensing and control functions into a centralized thermostat unit that wirelessly communicates with distributed actuators. By combining the intelligence and sensing in one unit while keeping the actuators simple and distributed, the system achieves multi-room precision control without the complexity of replicated intelligent units in each room.

Inventive Principle:
Principle #5Merging (Combining)
