Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing simulation systems are inadequate for efficiently performing various inspections and verifications of multiple facilities in a virtual space representation of a building, as they simply arrange facilities with state information without adequate three-dimensional representation and inspection tools.
Innovation Solution
A simulation system that includes a display processor to generate and display three-dimensional representations of a building's inner space with facilities, allowing for a movable viewpoint and a plan view display process to inspect facilities from different angles, including a two-dimensional projection of target facilities onto a projection plane.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If facilities are simply arranged in virtual space with state information, then the system structure is simple, but inspection and verification efficiency is insufficient
Solution Approach 1:
The patent applies dimensionality change by displaying facility information in multiple dimensions simultaneously - showing three-dimensional facility models in the virtual space while also projecting two-dimensional plan views onto the same space. This allows inspectors to view both spatial arrangement and detailed facility information without switching between different displays or modes, thereby improving inspection efficiency without significantly increasing system complexity
Solution Approach 2:
The patent merges the three-dimensional virtual space display with two-dimensional plan view information into a single integrated display. By projecting plan views onto the virtual space background, the system combines spatial visualization with detailed facility information in one view, allowing simultaneous inspection of both overall arrangement and specific facility details
2Measurement precision
If three-dimensional representation of facilities is added to improve inspection capability, then inspection detail is improved, but system complexity increases
Solution Approach 1:
The patent utilizes dimensionality change by overlaying two-dimensional plan views onto the three-dimensional virtual space. This allows the system to provide detailed facility information (improving inspection detail) while reusing the existing three-dimensional rendering engine and display infrastructure, thereby minimizing the increase in system complexity
Solution Approach 2:
The patent creates a two-dimensional plan view copy of facility information and projects it into the three-dimensional space. This copying approach allows detailed facility representation without requiring complex three-dimensional models of every facility component, as the plan views serve as simplified two-dimensional representations that convey essential inspection information

AI summary
A simulation system includes a display device that displays an image of a virtual space and a controller. The controller includes a space information obtainer, a facility information obtainer, and a display processor. The space information obtainer obtains inner space information representing an inner space of a building. The facility information obtainer obtains facility information representing each of multiple facilities arranged in the inner space. The display processor generates, in the virtual space, based on the inner space information and the facility information, a three-dimensional representation of the inner space of the building in which the multiple facilities are arranged, and causes the display device to display the three-dimensional representation. The display processor performs a plan view display process for causing displaying of a plan view of a target facility represented in two dimensions projected on a projection plane defining a part of the inner space.
