Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drawing verification systems face challenges in effectively verifying facility specifications, particularly when 2D design drawings are used, as they fail to accurately convey the layout of facility machines and traffic lines, making it difficult for unfamiliar individuals to grasp the layout, especially in cross-country orders where on-site visits are impractical.
Innovation Solution
A drawing verification system that utilizes a server and client apparatuses to create a virtual 3D space based on facility specifications, allowing multiple users to connect via a network for real-time verification through binocular stereoscopic vision, enabling the rendering and presentation of 3D models and facilitating collaborative verification and adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If 2D design drawings are used for verification, then the verification process can be performed with existing drawing data, but the layout of facility machines and traffic lines cannot be accurately conveyed to unfamiliar users
Solution Approach 1:
The patent transforms 2D design drawings into a 3D virtual space representation, allowing users to visually inspect facility layouts from multiple angles and perspectives. This dimensional transition enables intuitive comprehension of spatial relationships between facility machines and traffic lines, directly resolving the contradiction between conveying complete layout information and ensuring ease of understanding for unfamiliar users.
Solution Approach 2:
The system creates a virtual copy of the physical facility layout based on 2D drawing data, rendering it as an interactive 3D model. This virtual replica preserves all layout information while providing enhanced visual accessibility, allowing users to explore the facility arrangement without physical site visits.
2Reliability
If users visit the production facility on-site to verify drawing information, then accurate verification can be performed, but travel costs and time are required especially for cross-country orders
Solution Approach 1:
The patent creates a virtual replica of the production facility based on 2D drawing data, enabling users to inspect the facility layout remotely through a 3D visualization system. This virtual copy allows accurate verification without requiring physical travel to the site, thereby maintaining verification accuracy while eliminating time-consuming travel, especially for cross-country orders.
Solution Approach 2:
The system replaces the mechanical process of physical site visits with a digital 3D visualization system. Users interact with the virtual facility model through computational rendering and display devices, substituting the need for physical travel and on-site inspection while maintaining equivalent verification capability.
3Ease of operation
If a 3D virtual space is created for verification, then the layout can be accurately visualized and verified remotely, but system complexity increases with session management and real-time communication requirements
Solution Approach 1:
The patent divides the verification system into separate functional modules: a 3D rendering module that generates visual representations, a session management module that handles user connections and coordination, and a communication module that facilitates real-time interaction. This segmentation allows each component to be developed and optimized independently, managing overall system complexity while enabling easy remote verification.
Solution Approach 2:
The system introduces a server as an intermediary between client devices and the 3D virtual space. The server manages session establishment, coordinates real-time communication between multiple users, and handles the computational load of 3D rendering, thereby simplifying the client-side interface and enabling ease of operation without requiring complex client implementations.
4Adaptability or versatility
If multiple users connect to the same session for real-time verification, then collaborative inspection is enabled, but managing state information and shared information transmission becomes complex
Solution Approach 1:
The patent merges the state information management and information transmission functions into a centralized server-based system. The server maintains a unified state representation of the 3D virtual space and automatically distributes updates to all connected clients, enabling collaborative verification by multiple users while centralizing complexity management and simplifying individual client implementations.
Data Source
AI summary
In a system, a server establishes a session for verification of drawing information and implements information communication between clients connected to the session. The verification in the session is performed by laying out rendering object information used to render an object of the drawing information in a virtual 3D space based on layout information. The system comprises: establishing, upon receiving a session start request from one of the clients storing a verification target drawing information, the session to which the client storing the drawing information is able to connect; managing state information indicating a state of the 3D space for the session; receiving information of a verification input made at the clients; changing the state information upon receiving the verification input; and transmitting, to the connected clients, shared information necessary to render the 3D space.
