Solution Overview

Problem

Building automation systems face inefficiencies in managing room conditions, particularly in facilities like hospitals and hotels, where frequent changes in occupant needs require manual coordination and entry, leading to reduced efficiency, accuracy, and customer satisfaction.

Innovation Solution

A building automation system that integrates voice control with user preferences, utilizing information from hospitality and voice-enabled systems to automate room device management, correlating guest room profiles with hospitality user profiles and voice profiles to control environmental devices without revealing personal identifiable information, thus enhancing efficiency, speed, and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If manual coordination and entry are used to manage room conditions, then personnel can control environmental devices, but efficiency and accuracy are reduced due to frequent manual interventions

Engineering Contradiction:

ImproveefficiencyVSAvoidmanual coordination

Core Design Contradiction:

ProductivityVSExtent of automation

Solution Approach 1:

The system enables automatic self-adjustment of environmental devices based on occupancy detection and pre-configured user preferences. The building automation system autonomously correlates guest room profiles with hospitality user profiles and executes control actions without requiring manual coordination by personnel, thereby improving efficiency and reducing manual interventions in high-turnover facilities

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

User preferences and environmental parameters are pre-configured in the system before occupancy changes occur. When a new guest arrives or occupancy status changes, the system automatically retrieves pre-stored preferences and applies them immediately, eliminating the need for manual setup and accelerating the room preparation process

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If manual entry of occupant needs is performed, then room conditions can be adjusted, but accuracy and speed are reduced due to manual processing time

Engineering Contradiction:

ImproveaccuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system replaces manual data entry and processing with automated electronic data exchange between the building automation system and hospitality information systems. Occupant needs and preferences are automatically captured, correlated, and processed through digital interfaces, eliminating manual transcription errors and significantly reducing processing time while improving accuracy

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If personalized environmental control is implemented, then occupant satisfaction improves, but system complexity increases due to multiple profiles and preferences

Engineering Contradiction:

Improveoccupant satisfactionVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The building automation system is designed to universally handle multiple types of environmental devices (lighting, HVAC, curtains, entertainment) through a single integrated platform. The system can manage multiple user profiles and preferences simultaneously while providing a unified control interface, reducing the perceived complexity for occupants while delivering personalized control across diverse device types

Inventive Principle:

Principle #6Universality (Multi-functionality)

4Adaptability or versatility

If frequent room condition adjustments are made, then occupant needs are met, but energy consumption increases due to continuous system changes

Engineering Contradiction:

Improveoccupant needsVSAvoidenergy consumption

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The system implements periodic occupancy detection and condition assessment rather than continuous adjustment. Environmental parameters are monitored and adjusted at appropriate intervals based on occupancy status changes, ensuring occupant needs are met while avoiding unnecessary frequent adjustments that would waste energy. The system intelligently determines when adjustments are truly needed versus when current conditions remain acceptable

Inventive Principle:

Principle #19Periodic action

AI summary

There is described a building automation system (306) for controlling conditions of a room (310). The building automation system (306) comprises a room device (328-332), a first interface (322), a second interface (324), and a managing device (for example, 404-408). The first interface (322) receives a voice command based on a voice utterance detected in the room (310) by the voice enabled system (302, 304). The second interface (324) receives a hospitality user profile from a hospitality information system (308). The hospitality user profile identifies one or more user parameters associated with the room (310). The managing device of the building automation system (306) includes a guest room profile that identifies one or more room parameters associated with the room (310). The managing device controls the room device (328-332) based on the voice command, the hospitality user profile, and the guest room profile.
