Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing three-dimensional measuring apparatus requires operators to work in pairs, leading to inefficiencies due to delayed communication and varying criteria for determining measurement precision, which degrades working efficiency and can be influenced by operator experience.
Innovation Solution
An image projection measuring apparatus that projects image projection data onto the work surface, allowing operators to check measurement precision in real-time using a camera and image projector, while the measurer illuminates the surface with a line laser, enabling immediate identification and remeasurement of areas with low precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators work in pairs to check measurement precision, then measurement precision can be verified, but working efficiency decreases due to delayed communication and varying criteria
Solution Approach 1:
The patent creates a visual copy of the workpiece surface by projecting image projection data onto it. This projected image serves as an objective reference that both operators can view simultaneously, eliminating the need for subjective comparison and delayed communication between operators.
Solution Approach 2:
The projected image acts as an intermediary reference between the operators and the workpiece. Instead of operators directly comparing measurements against each other or against mental criteria, they both reference the same projected image, creating a common objective standard.
2Adaptability or versatility
If operators use varying criteria for determining measurement precision, then flexibility is maintained, but consistency and reliability of measurement deteriorate
Solution Approach 1:
The system allows different regions of the workpiece to be measured and projected with appropriate local characteristics. The image projection data can be selectively projected onto specific areas, allowing operators to adapt to different measurement requirements while maintaining consistent reference standards across all regions.
