Cloud-Controlled Device Configuration for Manufacturing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manufacturing processes for complex electronic devices require vendors to frequently update software, firmware, and testing procedures, which often disrupt the manufacturing process due to the need for training contract manufacturers, leading to inefficiencies and potential errors.
Innovation Solution
A cloud-based system that allows vendors to remotely define, update, and manage software, firmware, and test procedures for contract manufacturers, enabling seamless integration and monitoring of manufacturing processes through cloud service interfaces, device images, and tester images accessible over networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vendors provide software, firmware, and test procedures to contract manufacturers, then the contract manufacturer can manufacture the device, but any changes require instruction or training that interrupts the manufacturing process
Solution Approach 1:
The contract manufacturer's testing system automatically retrieves updated test procedures, software, and firmware from the vendor's server without requiring manual intervention. The system self-updates by comparing version numbers and automatically downloading new versions, eliminating the need for training interruptions while maintaining manufacturing productivity.
2Reliability
If vendors update software or firmware during manufacturing, then the device can be improved, but the contract manufacturer needs retraining which causes interruptions
Solution Approach 1:
The vendor uploads updated software, firmware, and test procedures to the server before the contract manufacturer needs them. The contract manufacturer's system automatically detects and downloads updates during non-critical periods, ensuring the latest versions are ready before manufacturing cycles begin, thus eliminating training time losses.
3Adaptability or versatility
If vendors want to change device testing procedures, then they can test for new defects or updated firmware, but the contract manufacturer must be trained on new procedures
Solution Approach 1:
A centralized server acts as an intermediary between the vendor and the contract manufacturer's testing system. The vendor uploads new test procedures to the server, and the contract manufacturer's system automatically retrieves and implements them, eliminating the need for direct training and simplifying the implementation process.
4Productivity
If the contract manufacturer uses locally stored test procedures and software, then they can manufacture devices, but they cannot easily receive updates from the vendor
Solution Approach 1:
The contract manufacturer's testing system automatically checks the vendor's server for updated software, firmware, and test procedures by comparing version numbers. When updates are detected, the system automatically downloads and implements them, ensuring continuous access to the latest information without disrupting manufacturing efficiency.

AI summary
A manufacturer (120) of a device (140) uses a tester image (134) from a cloud service (130) when configuring test equipment (150) for testing of a device (140) being manufactured, and the device (140) contacts the cloud service (130) and installs firmware or software (146) based on a device image (132). A vendor or developer (110) can change or update the images (132, 134) to update a manufacturing process without needing the manufacturer (120) to have special training or knowledge. Further, the cloud service (130) can receive test results from the manufacturer (120) and may record access to image (132), enabling the vendor (110) to monitor manufacturing of the device (140).
