Part Mounting Position Guidance Device for Complex Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complexly structured machines, operators face difficulty in identifying the mounting position of defective parts, especially when these parts are located on side or rear surfaces, as conventional guidance methods do not effectively account for variations in machine structure and operator familiarity with these areas.
Innovation Solution
A part mounting position guidance device that acquires position order data and uses a display device to guide operators from a predetermined machine position to the mounting position of a part, incorporating correspondence relationships between position information and machine structure images, and triggering guidance based on alarms, using still images and movies with sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional guidance methods are used to specify defective parts, then the defective part can be identified, but the mounting position is difficult to recognize when the part is located on side or rear surfaces of complex machines
Solution Approach 1:
The patent transitions from two-dimensional drawings to three-dimensional virtual reality visualization, allowing operators to view machine structures from multiple angles including side and rear surfaces. This dimensional enhancement enables accurate location of mounting positions that are difficult to interpret in conventional 2D representations.
Solution Approach 2:
The system creates a virtual copy of the actual machine structure that mirrors the physical layout. This virtual model allows operators to interact with and explore the machine structure without physically moving around the actual equipment, providing clear visualization of hard-to-reach areas through the virtual representation.
2Loss of information
If detailed internal structure drawings are provided to show mounting positions, then mounting positions can be identified, but operators unfamiliar with side and rear surface structures still cannot easily locate parts
Solution Approach 1:
The virtual reality system allows dynamic interaction where operators can rotate, zoom, and navigate through the machine structure from any angle. This dynamic exploration replaces static drawings with an interactive experience that adapts to the operator's needs, eliminating the requirement for pre-existing familiarity with specific viewing angles or structural layouts.
Solution Approach 2:
The system pre-renders and structures all possible viewing angles and structural details in the virtual model before the operator arrives. This preliminary preparation ensures that when the operator accesses the system, all mounting position information is already organized and accessible, eliminating the need to mentally reconstruct or interpret complex drawings during troubleshooting.
3Measurement precision
If operators must physically navigate to side and rear surfaces to locate parts, then accurate position identification is possible, but time is lost traveling and searching
Solution Approach 1:
By creating a faithful virtual copy of the machine structure, the system eliminates the need for physical navigation. Operators can instantly access any mounting position in the virtual model, obtaining accurate spatial information without the time cost of physically traveling to side or rear surfaces of the actual machine.
Solution Approach 2:
The system replaces the mechanical action of physically moving to locate parts with an information-based virtual navigation system. Instead of using body movement and physical exploration, operators use the virtual reality interface to instantly access precise mounting position data, substituting mechanical navigation with digital information retrieval.
