Solution Overview

Problem

Existing HVAC control systems lack personalization and adaptability to individual user preferences, often relying on centralized control that does not account for user-specific usage patterns, leading to suboptimal thermal comfort and inefficient energy usage.

Innovation Solution

An adaptive HVAC control system with a remote control and communication unit that learns user preferences from historical settings, using occupant recognition and data clustering to adjust temperature settings based on individual or average user preferences, allowing for multi-zoning and energy-efficient operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If a centralized control system is used to optimize energy usage, then energy efficiency is improved, but adaptability to individual user preferences deteriorates

Engineering Contradiction:
Improveenergy efficiencyVSAvoidadaptability to user preferences
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The system segments user profiles and preferences into distinct, manageable units that can be individually processed and applied. Each user's historical settings and preferences are stored as separate profile data, allowing the control system to selectively apply appropriate segments based on detected occupancy, thereby achieving both energy efficiency and user-specific adaptability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs preliminary actions by pre-processing and storing user preference data in advance. Historical settings are analyzed and stored as user profiles before actual HVAC operation, enabling the system to quickly retrieve and apply appropriate preferences without real-time computation delays, thus optimizing both energy usage and user comfort

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If user preferences are stored and processed locally at temperature control means, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveuser preference adaptationVSAvoidcontrol system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system extracts the complex user profile processing and storage functions from the local temperature control means and relocates them to a remote control unit. This extraction allows the thermostat to remain simple while still providing sophisticated user-adaptive control through the remote unit that manages all profile-related operations

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A remote control unit is introduced as an intermediary between the user/environment and the temperature control means. This intermediary handles the complex tasks of storing user profiles, detecting occupancy, and determining appropriate temperature settings, thereby shielding the simple thermostat from complexity while maintaining high adaptability

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If traditional HVAC control systems are used, then ease of operation is maintained, but thermal comfort optimization deteriorates

Engineering Contradiction:
Improvesystem operation simplicityVSAvoidthermal comfort optimization
Core Design Contradiction:
Ease of operationVSTemperature

Solution Approach 1:

The system performs self-service by automatically detecting occupancy and retrieving appropriate user profiles without requiring user input. The control unit autonomously determines which user preferences to apply based on detected presence, eliminating the need for manual thermostat adjustments while optimizing thermal comfort for each occupant

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by continuously monitoring occupancy status and automatically adjusting temperature settings based on stored user profiles. This closed-loop feedback ensures thermal comfort optimization occurs automatically, maintaining ease of operation while significantly improving temperature control accuracy

Inventive Principle:
Principle #23Feedback
