Dynamic Geometrical Data Transmission for Irregular Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional object geometry measurement systems face limitations in transmitting high-resolution geometrical data for irregularly shaped objects due to bandwidth and processing capacity constraints, resulting in imprecise or incomplete spatial location and orientation information.
Innovation Solution
The system dynamically generates and transmits geometrical data by outputting information only when significant changes occur in the object's shape, using a line scan sensor to detect edges and corners, and adjusting the data density based on gradient thresholds, allowing for high-resolution data transmission with a limited amount of data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If geometrical data are transmitted at regular intervals to ensure continuous data flow, then the data transmission is systematic and predictable, but the resolution of geometrical data is restricted and imprecise for non-parallelepiped-shaped objects
Solution Approach 1:
The patent applies dynamics by making the data transmission interval variable rather than fixed. The control device dynamically adjusts the transmission timing based on detected changes in object geometry. When significant geometrical changes are detected, data transmission occurs immediately; when changes are minimal, transmission is delayed. This dynamic approach resolves the contradiction by adapting the transmission rate to the actual information content, achieving high resolution where needed while minimizing data volume overall.
Solution Approach 2:
The patent changes the parameter of transmission interval from a constant value to a variable value based on geometrical change detection. By monitoring parameters such as boundary position, object width, or height across successive scan lines and comparing them to threshold values, the system adjusts the transmission timing parameter dynamically. This parameter change enables precise geometrical data transmission only when necessary, resolving the contradiction between resolution and data quantity.
2Measurement precision
If the transmission interval is reduced to improve geometrical precision, then the resolution of spatial location and orientation is improved, but the data transmission load increases beyond the capacity of the data path or processing system
Solution Approach 1:
The patent applies partial action by transmitting geometrical data selectively rather than continuously. Instead of transmitting data at every possible interval, the system transmits data only when specific conditions are met - namely when geometrical changes exceed predetermined thresholds. This partial transmission approach achieves sufficient spatial precision for accurate object representation while keeping the data transmission load within the capacity of the data path and processing system.
Solution Approach 2:
The patent extracts only the essential geometrical information that has changed beyond threshold values, rather than transmitting all geometrical data continuously. By identifying and extracting only the significant changes in object geometry (such as changes in boundary position, width, or height that exceed thresholds), the system achieves high spatial precision where needed while minimizing the overall data transmission load to match the capacity of the data path and processing system.
3Quantity of substance
If a low number of pieces of intermediate information is used to describe object geometry, then the data amount is limited and manageable, but the information on spatial location and orientation is imprecise or incomplete for irregularly shaped objects
Solution Approach 1:
The patent applies local quality by applying different transmission densities to different regions of the object based on their geometrical characteristics. For regions with regular, predictable geometry, the system uses coarser transmission intervals. For regions with irregular geometry or significant changes, the system increases transmission density locally. This local adaptation allows the system to maintain high spatial information completeness for irregular shapes while keeping the overall data amount manageable.
Solution Approach 2:
The patent performs preliminary detection of geometrical changes before triggering data transmission. The control device continuously monitors geometrical parameters (boundary position, width, height) and compares them against threshold values in advance. When changes exceed thresholds, the system is prepared to transmit data at the appropriate moment. This preliminary action ensures that sufficient spatial information is captured for irregular shapes while avoiding unnecessary transmissions that would increase data volume.
