Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current inventory management systems face challenges in providing real-time usage status of loading spaces due to increased database load and responsiveness degradation, especially when managing diverse and numerous inventory items across various warehouse spaces.
Innovation Solution
An apparatus and method that calculates and updates the state change amount for each space unit based on location and space information, allowing for quick and accurate management of inventory by transmitting updated information to a storage system, thereby reducing the load on relational databases and enhancing responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If inventory information and loading space information are separately recorded in relational database tables and accessed individually for each space, then data organization and management are simplified, but database load increases and responsiveness degrades
Solution Approach 1:
The patent combines inventory information and loading space information into a single integrated data structure that can be accessed in one operation. Instead of querying separate tables for inventory status and space usage, the system merges these data elements so that both can be retrieved simultaneously, reducing the number of database accesses required and improving responsiveness while maintaining organized data management.
Solution Approach 2:
The patent performs preliminary calculation and combination of inventory and space data in advance, storing the results in a pre-computed format. This allows the system to quickly retrieve usage status information without performing multiple sequential queries at the time of access, thereby reducing database load and improving response time for real-time inventory management operations.
2Measurement precision
If multiple sequential accesses to relational database tables are performed to acquire usage status of loading spaces, then accurate inventory and space information can be obtained, but calculation time increases and real-time monitoring becomes difficult
Solution Approach 1:
The patent merges inventory data and loading space data into a unified data structure that contains both types of information. This integration allows the system to retrieve accurate inventory status and space usage information in a single access operation, eliminating the need for multiple sequential queries while maintaining data accuracy and enabling real-time monitoring capabilities.
Solution Approach 2:
The system performs preliminary computation to combine inventory and space information into pre-calculated usage status data. By preparing this combined information in advance and storing it in an optimized format, the system can quickly retrieve accurate usage status without performing time-consuming sequential calculations at query time, thus reducing calculation time while maintaining precision.
3Reliability
If comprehensive inventory management is performed for numerous items across various warehouse spaces, then complete inventory control is achieved, but database load increases and system responsiveness degrades
Solution Approach 1:
The patent implements a merged data structure that integrates inventory information, loading space information, and usage status into a single unified representation. This approach allows comprehensive inventory control across all warehouse spaces to be achieved through a single data access operation, maintaining complete inventory visibility while reducing the number of database operations required and improving overall system responsiveness.
