Solution Overview

Problem

Existing HVAC thermostatic control systems either lack programmability, leading to missed energy-saving opportunities, or are overly complex, intimidating users and often defaulting to manufacturer settings, resulting in suboptimal energy usage.

Innovation Solution

A user-friendly, network-connected thermostat with a processing system that automatically identifies HVAC connectors, presents user inquiries to determine system components, and modifies configuration based on user input, allowing for easy DIY installation while accommodating complex systems and potentially requiring professional assistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If programmable thermostats with multiple settings are provided, then energy-saving control capability is improved, but device complexity increases and ease of operation deteriorates

Engineering Contradiction:
Improveenergy-saving control capabilityVSAvoiduser operation simplicity
Core Design Contradiction:
Use of energy by moving objectVSEase of operation

Solution Approach 1:

The thermostat performs self-configuration by automatically detecting HVAC connectors and system components during installation, eliminating the need for users to manually configure complex settings. The system serves itself by gathering necessary information through automated detection and user-friendly inquiries, resolving the contradiction between providing comprehensive energy-saving controls and maintaining ease of operation.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automated HVAC connector identification is implemented, then installation ease is improved, but device complexity increases

Engineering Contradiction:
Improveinstallation easeVSAvoiddetection system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The thermostat performs preliminary automated detection of HVAC connectors and system components during the installation phase, gathering all necessary configuration information before the user begins operation. This preliminary action simplifies the installation process for users while containing the detection complexity within the initial setup phase rather than requiring ongoing complex operations.

Inventive Principle:
Principle #10Preliminary action

AI summary

Arrangements for configuring a thermostat for controlling a heating, ventilation, and air conditioning (HVAC) system are presented. A thermostat may receive information indicative of the HVAC system comprising an air conditioner and information indicative of the HVAC system comprising a multi-stage heat pump. The thermostat may modify configuration information of the thermostat based on the information indicative of the air conditioner and the information indicative of the multi-stage heat pump. The thermostat may then control the HVAC system in accordance with the modified configuration information.
