Part Compatibility Matching for Construction Machine Spare Procurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in quickly addressing various malfunctions of construction machines, as there are numerous models and limited storage space and resources for spare parts, making it difficult to identify and procure the necessary parts to minimize downtime effectively.
Innovation Solution
A part procurement system that uses a control device to input customer requirements, BOM, CAD, and part compatibility information to extract candidate parts and alternatives, displaying them for selection, thereby facilitating quick procurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the agency stores many kinds of parts to cope with all troubles, then the ability to quickly address malfunctions improves, but storage space requirements and costs increase
Solution Approach 1:
The patent applies universality by enabling parts to serve multiple functions across different construction machine models. The part compatibility database and BOM information system identify parts that can be substituted across different models, allowing a single part to cope with multiple trouble scenarios. This reduces the total variety of parts needed in storage while maintaining the ability to address diverse malfunctions.
Solution Approach 2:
The system changes the parameter of part identification from model-specific to compatibility-based. By using BOM information, CAD data, and compatibility databases, the system transforms part selection from a fixed model-dependent process to a flexible compatibility-matching process, enabling the same part to serve multiple models based on parameter matching rather than model identity.
2Reliability
If the agency stores many kinds of parts to cope with all troubles, then the ability to quickly address malfunctions improves, but costs increase
Solution Approach 1:
The patent reduces costs by making parts universal across multiple construction machine models. The compatibility database and BOM matching system identify parts that can substitute for each other across different models, reducing the total inventory needed. This decreases both storage costs and capital tied up in spare parts while maintaining comprehensive coverage for troubleshooting.
3Adaptability or versatility
If there are numerous models of construction machines, then the versatility of the system improves, but the difficulty of identifying and procuring necessary parts increases
Solution Approach 1:
The system applies self-service by enabling automatic part identification and compatibility matching through the control device. The system autonomously queries the compatibility database, matches BOM information, and identifies suitable parts without requiring manual expertise. This automates the complex process of navigating numerous models and their specific part requirements, reducing the burden on service personnel.
Solution Approach 2:
The system uses feedback mechanisms where the control device queries the compatibility database and BOM information, receives matching results, and uses this information to guide part selection. The iterative process of querying compatibility data and refining part identification based on feedback from the database reduces complexity by providing structured guidance through the variety of models.
4Adaptability or versatility
If construction machines operate at remote places away from agencies, then the operational flexibility improves, but the time required to cope with malfunctions increases
Solution Approach 1:
The system applies preliminary action by pre-establishing the compatibility database and BOM information repositories that contain all necessary part compatibility data. When a malfunction occurs at a remote location, the serviceman can immediately query this pre-prepared information without needing to wait for expert analysis or model-specific documentation, significantly reducing response time while maintaining operational flexibility.

AI summary
In a part procurement system including a control device performing procurement of a part required by a customer, to the control device, customer's requirements information about the procured part inputted via a data input device, and at least BOM information that is part table information, CAD information that is computer-aided design information and part compatibility information, which are stored in a file server, are inputted; and the control device extracts candidate parts including candidates for the part required by the customer and alternatives for the part, based on the BOM information, the CAD information and the part compatibility information that have been inputted, and outputs a signal for displaying the extracted candidate parts on a display device.
