3D Building Information Device for HVAC Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building automation systems (BAS) require three-dimensional (3D) information to efficiently control and monitor building equipment, but existing technologies primarily use two-dimensional (2D) graphics, limiting the ability to magnify, rotate, and translate objects, making it difficult to effectively manage and control complex building systems.
Innovation Solution
A 3D information providing device that includes a data communication unit to receive sensor data, a graphic unit to display 3D device images, and a control point binding unit to control equipment, allowing for the generation of 3D graphic monitoring screens by dragging and dropping 3D device images, binding control points, and receiving data from sensors, enabling remote control and management of building equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 2D plane graphics are used for building control, then the system is simple to implement, but the ability to magnify, rotate, and translate objects is limited
Solution Approach 1:
The patent transitions from 2D plane graphics to 3D graphical interfaces, enabling objects to be magnified, rotated, and translated in three-dimensional space. This dimensional upgrade provides enhanced adaptability for building control while maintaining system manageability through standardized 3D components.
2Ease of operation
If 3D graphics are implemented for building control, then object manipulation flexibility improves, but system complexity increases
Solution Approach 1:
The system adopts 3D graphical interfaces that allow intuitive manipulation of building equipment representations through dragging, dropping, rotating, and scaling operations, significantly improving ease of operation despite the increased graphical complexity.
Solution Approach 2:
The patent uses 3D model copies of building equipment that can be manipulated in virtual space without affecting physical systems directly. These digital twins or virtual representations allow flexible operation testing and configuration before implementation.
3Adaptability or versatility
If unique graphic editors are used for each building control function, then specific functions can be precisely controlled, but the number of editors and system complexity increases
Solution Approach 1:
The patent implements a universal 3D graphic editor that can handle multiple building control functions (HVAC, lighting, security, etc.) through a single integrated interface. This multi-functional editor reduces the number of separate tools needed while maintaining comprehensive function coverage through standardized 3D components and parameters.

AI summary
Provided is a three-dimensional (3D) information providing device which reads values of sensors provided in equipment in a building, displays the sensor values on a 3D graphic monitoring screen, and controls the actual equipment in the building by using output values or control values of 3D device images corresponding to the equipment on the 3D graphic monitoring screen.
