Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Complex manufacturing processes, such as those in absorbent article production, require efficient tracking and automation across multiple suppliers, machines, and distribution entities, which existing systems fail to effectively manage due to their complexity and lack of real-time data integration.
Innovation Solution
The implementation of a decentralized industrial control network utilizing blockchain technology and smart contracts to coordinate manufacturing processes, allowing for real-time data integration and autonomous decision-making across the supply chain, including material sourcing, production planning, and logistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a decentralized industrial control network using blockchain technology is implemented, then transparency, autonomy, and coordination efficiency of manufacturing processes are improved, but device complexity and implementation difficulty increase
Solution Approach 1:
The system segments the manufacturing control network into autonomous endpoint nodes (manufacturing equipment, controllers, sensors) that each independently manage their own data and processes. Each node operates autonomously while contributing to the overall supply chain coordination through the distributed ledger, thereby improving transparency without requiring centralized control infrastructure.
Solution Approach 2:
The distributed ledger (blockchain) serves as an intermediary layer that enables autonomous endpoint nodes to communicate and coordinate without requiring complex centralized control systems. The smart contracts on the ledger act as automated mediators that enforce business rules and facilitate transactions between suppliers, manufacturers, and distributors, reducing the need for intricate human-managed control mechanisms.
2Loss of information
If real-time data integration across multiple suppliers, machines, and distribution entities is achieved, then supply chain visibility and production optimization are improved, but information management complexity and data integration difficulty increase
Solution Approach 1:
The system merges data from multiple independent sources (suppliers, manufacturing machines, distributors, sensors) into a single distributed ledger that all participants access in real-time. This unified view eliminates information silos and provides end-to-end supply chain visibility without requiring complex data aggregation infrastructure, as each node contributes data directly to the shared ledger.
Solution Approach 2:
The distributed ledger platform serves multiple functions simultaneously: it acts as a database for storing supply chain data, a communication channel for node-to-node transactions, a verification system through consensus mechanisms, and an execution platform for smart contracts. This multi-functionality reduces the need for separate specialized systems for each data integration task.
3Productivity
If autonomous decision-making capabilities are enabled across the supply chain, then production responsiveness and efficiency are improved, but control system complexity and automation requirements increase
Solution Approach 1:
Endpoint nodes in the system are designed to be self-sufficient, autonomously generating, validating, and submitting their own data to the distributed ledger without requiring manual intervention or complex centralized control. Manufacturing equipment automatically reports production status, suppliers autonomously update inventory levels, and distributors independently manage order fulfillment, with all actions verified through consensus mechanisms.
Solution Approach 2:
The system uses smart contracts with adjustable parameters and conditions that allow autonomous decision-making based on real-time data. Business rules, thresholds, and decision criteria are encoded as configurable parameters in the smart contracts, enabling flexible automation that can adapt to changing production requirements without requiring reprogramming of the entire control system.
