Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current component procurement methods for long-term use equipment, such as construction machines and railways, face challenges with delivery time and durability, particularly when using recycled or new components, as they are not satisfactory in maintaining quick and reliable quality maintenance.
Innovation Solution
A management system that combines procurement of components using a 3D printer with genuine components, where a processor simulates molding a spare component using a 3D printer and evaluates its durability, determining its applicability until a genuine component is procured, thereby optimizing component procurement by comparing the two.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a genuine component is procured through traditional channels, then the component has high durability and reliability, but the procurement time is long and delivery is delayed
Solution Approach 1:
The system performs preliminary simulation and evaluation of 3D-printed spare components before actual failure occurs. By pre-assessing the durability and applicability of alternative components through virtual molding simulation, the system prepares viable replacement options in advance, enabling rapid deployment when failure occurs without waiting for traditional procurement channels.
Solution Approach 2:
The system creates a digital copy or virtual model of the genuine component and uses it to simulate the molding process for producing spare components. This virtual copying allows evaluation of spare component quality without requiring physical prototypes, significantly reducing assessment time while maintaining reliability standards.
2Loss of time
If a spare component is manufactured using a 3D printer on demand, then the procurement time is reduced and equipment restoration is faster, but the component durability and quality may be insufficient
Solution Approach 1:
The system performs preliminary simulation and evaluation of 3D-printed spare components before actual failure occurs. By pre-assessing the durability and applicability of alternative components through virtual molding simulation, the system prepares viable replacement options in advance, enabling rapid deployment when failure occurs without waiting for traditional procurement channels.
Solution Approach 2:
The system implements a feedback mechanism where simulation results of spare component molding are continuously evaluated against genuine component standards. The evaluation feedback loop compares key durability parameters and provides guidance for optimizing the 3D printing process, ensuring that rapidly produced spare components meet minimum reliability thresholds.
3Reliability
If only genuine components are used for procurement, then the quality and reliability are ensured, but the procurement flexibility and responsiveness to sudden failures are reduced
Solution Approach 1:
The system creates a universal procurement framework that can handle multiple component types and procurement scenarios through a single integrated platform. The determination module can evaluate both genuine and spare components using the same simulation and assessment procedures, providing flexible procurement options while maintaining consistent quality standards across different component sources.
Solution Approach 2:
The system dynamically adjusts procurement strategies based on real-time conditions such as component availability, urgency of replacement, and simulation results. Rather than following a fixed procurement protocol, the system can adaptively select between genuine components and 3D-printed spares, optimizing both reliability and responsiveness to varying operational needs.
4Ease of manufacture
If component procurement relies solely on traditional channels, then the process is simple and straightforward, but the delivery time is long and cannot meet urgent maintenance needs
Solution Approach 1:
The system enables self-service procurement where the determination module automatically evaluates component options, simulates molding parameters, and determines applicability without requiring extensive manual intervention. This automated self-assessment capability maintains process simplicity while dramatically accelerating procurement speed, allowing urgent maintenance needs to be addressed efficiently.
