Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processing systems face challenges in accurately processing objects by efficiently combining measurement and control data from different areas of an object's surface, leading to incomplete or inaccurate processing due to limitations in measurement coverage and reliability of model information.
Innovation Solution
A processing system that integrates a processing apparatus, a measurement apparatus, and a control apparatus, where the control apparatus uses both measured data from a first area and model information to calculate and correct the shape and position of a second area, allowing for precise processing without repeated positional adjustments, thereby improving throughput and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If measurement apparatus measures only the first area of the object surface, then measurement time is reduced and throughput is improved, but processing accuracy of the second area deteriorates due to lack of direct measurement data
Solution Approach 1:
The patent creates a virtual copy of the object's three-dimensional shape by calculating the second area's shape information based on the measured first area data and stored model information. This virtual copy enables processing control without direct physical measurement of the second area, thus improving throughput while maintaining processing accuracy through the calculated shape data.
Solution Approach 2:
The patent introduces model information as an intermediary element that bridges the measured first area data and the unmeasured second area. By combining actual measurement data with pre-stored model information, the system derives accurate shape information for areas not directly measured, resolving the contradiction between measurement speed and processing accuracy.
2Speed
If the system uses calculated three-dimensional shape information from model information, then processing speed is improved and repeated measurements are eliminated, but reliability of the shape data deteriorates due to dependence on model accuracy
Solution Approach 1:
The patent performs preliminary actions by pre-storing three-dimensional model information of the object before the processing step. This allows the system to quickly calculate shape information during processing without repeated measurements, improving speed while maintaining reliability through the use of accurate pre-acquired model data combined with actual measurement data from the first area.
3Manufacturing precision
If the control apparatus uses both measured data and model information to calculate shape of the second area, then processing accuracy is improved, but system complexity increases due to integration of multiple data sources
Solution Approach 1:
The patent merges measured data from the first area with pre-stored model information to calculate the three-dimensional shape information of the second area. This combination of actual measurement data and model data improves processing accuracy by compensating for the limitations of each individual data source while the integration is managed through a coordinated control apparatus.
