Solution Overview

Problem

In large commercial or industrial facilities, HVAC system components are often located in environments where the HVAC control system cannot run due to unavailable data networks, and the space is too cramped for users to operate laptops or smartphones effectively, requiring users to constantly move between the device and the testing location.

Innovation Solution

An adaptive user interface system that includes a wireless headset and computing device with a multimodal user interface, allowing users to communicate voice commands and receive information about HVAC components, even in noisy environments, enabling them to stay in one location while testing without needing to move between the device and the testing site.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the HVAC control system runs on a laptop or smartphone, then the user can access the system and enter/observe information, but the user must constantly move between the device and the testing location, reducing productivity

Engineering Contradiction:
Improveaccess to HVAC control systemVSAvoidtesting efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces the mechanical interaction of physically moving to a fixed computing device with a wireless communication system. The headset captures voice commands and transmits them wirelessly to the HVAC control system, allowing the user to remain at the testing location while maintaining full system access and information display capabilities.

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

2Productivity

If the user stays at the testing location, then productivity improves, but the user cannot access the HVAC control system or enter/observe information without a fixed computing device

Engineering Contradiction:
Improvetesting efficiencyVSAvoidaccess to HVAC control system
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent introduces a wireless headset as an intermediary device between the user and the HVAC control system. The headset captures voice commands, transmits them wirelessly to the control system, and can display information, serving as a mobile intermediary that enables system access without requiring a fixed computing device location.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If the environment is noisy, then voice recognition may fail, but the user needs hands-free operation to effectively test HVAC components

Engineering Contradiction:
Improvehands-free operationVSAvoidvoice recognition accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent implements feedback mechanisms where the system can confirm received commands and display information back to the user through the headset. This feedback loop allows the user to verify that voice commands were correctly interpreted despite noisy environmental conditions, and to reissue commands if necessary, thereby maintaining reliable hands-free operation.

Inventive Principle:
Principle #23Feedback
