Solution Overview

Problem

Existing temperature control systems waste energy due to inefficiencies in detecting and addressing energy waste states, such as open windows or unexpected heat sources, as they rely on preset temperatures without considering actual room conditions.

Innovation Solution

A system and method that uses a supervisory controller to estimate heat change based on indoor and outdoor temperature historical data, allowing for accurate detection of energy waste states and taking intervention actions like shutting down temperature control units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If temperature control systems run on preset temperatures, then the system is simple and easy to control, but energy waste occurs as the system cannot detect or respond to energy waste states

Engineering Contradiction:
Improveease of controlVSAvoidenergy waste
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system continuously monitors indoor temperature, outdoor temperature, and temperature control unit operation status, then feeds this information back to the controller which detects energy waste states and adjusts operation accordingly. This closed-loop feedback mechanism enables automatic detection and response to energy waste conditions while maintaining simple user interaction through preset temperatures.

Inventive Principle:
Principle #23Feedback

2Device complexity

If temperature control systems use preset temperatures for all rooms, then the control system is simple, but energy waste states are not detected and energy consumption increases

Engineering Contradiction:
Improvesystem complexityVSAvoidenergy waste
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The temperature control system automatically monitors its own operation status, outdoor temperature conditions, and indoor temperature responses to detect energy waste states without requiring complex user configuration or intervention. The controller self-adjusts by identifying when energy waste occurs and modifying temperature control unit operation accordingly, enabling the system to serve itself in detecting and responding to energy waste conditions.

Inventive Principle:
Principle #25Self-service

3Loss of energy

If the system continuously monitors and adjusts temperature control, then energy waste is reduced, but system complexity and computational requirements increase

Engineering Contradiction:
Improveenergy waste detectionVSAvoidcontroller complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical or manual energy waste detection mechanisms with electronic sensors and computational algorithms. Temperature sensors continuously monitor indoor and outdoor conditions, while the controller uses computational logic to analyze the relationship between temperature data and energy consumption patterns, automatically detecting energy waste states without requiring complex hardware modifications.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
