Assembly Image Capture Control for Accurate Process Documentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current assembly process documentation methods rely heavily on human operators, leading to potential mistakes such as capturing incorrect images or reading wrong barcodes/QR codes during the assembly of parts.
Innovation Solution
An assembly process documentation system that includes an image capturing device and a control system to ensure the device is positioned and oriented correctly relative to a reference point before enabling image capture, thereby reducing the risk of incorrect documentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator manually documents assembly steps, then flexibility and ease of operation are maintained, but reliability deteriorates due to human errors
Solution Approach 1:
The system enables self-service documentation by allowing the image capturing device to automatically determine its own position and orientation relative to the object, and autonomously enable or disable itself based on whether documentation conditions are met, eliminating the need for operator judgment
Solution Approach 2:
The control system continuously monitors the position and orientation of the image capturing device, compares it against reference data, and provides feedback by enabling or disabling the device accordingly, creating a closed-loop control system that ensures documentation accuracy
2Measurement precision
If position and orientation verification is implemented, then documentation accuracy is improved, but device complexity increases
Solution Approach 1:
The patent introduces an intermediary control system that acts as a mediator between the image capturing device and the documentation process. This control system handles the complex position and orientation verification logic, keeping the main device relatively simple while achieving precise control through the intermediary layer
3Productivity
If automatic position and orientation determination is added, then productivity is improved by reducing errors, but device complexity increases
Solution Approach 1:
The patent replaces manual mechanical operations (operator physically positioning and verifying device orientation) with automated electronic/digital systems that use sensors, processors, and software algorithms to determine position and orientation, thereby reducing physical complexity while improving productivity
