Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing information collection and display systems, acquiring desired site data is hindered when external data lacks a connection key, necessitating costly modifications or new system implementations.

Innovation Solution

An information system that includes a link logic definition unit to define correspondence relations between item values of site data and reference values of external data, and a link logic data acquisition unit to acquire item values using this link logic, even when external data lacks a connection key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If external data is collected using an existing system different from the site data collection system, then data collection can be performed using existing infrastructure, but the external data does not necessarily have the connection key making it difficult to acquire desired site data

Engineering Contradiction:

Improveease of data collectionVSAvoiddata acquisition capability

Core Design Contradiction:

Ease of manufactureVSLoss of information

Solution Approach 1:

The patent introduces an intermediary component (the information system with link logic definition unit and link logic data acquisition unit) that mediates between external data sources and the site data collection system. This intermediary translates and correlates data from different systems without requiring modification of the existing external systems, enabling data acquisition while maintaining system independence.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments the data acquisition function into independent components: the link logic definition unit that holds correspondence relations, and the link logic data acquisition unit that executes the acquisition. This segmentation allows the system to handle external data without connection keys by processing it through dedicated acquisition logic rather than requiring integrated system architecture.

Inventive Principle:

Principle #1Segmentation

2Loss of information

If the structure of external data is changed to provide connection keys, then data acquisition becomes possible, but modification or introduction of new systems is required causing cost increase

Engineering Contradiction:

Improvedata acquisition capabilityVSAvoidimplementation cost

Core Design Contradiction:

Loss of informationVSEase of manufacture

Solution Approach 1:

Instead of modifying external data to add connection keys (traditional approach), the patent inverts the approach by modifying the acquisition side to work with existing external data structures. The link logic definition unit defines correspondence relations between external data and site data without requiring changes to the external data sources, thereby avoiding implementation costs.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent creates a virtual copy of the connection key functionality through the link logic definition unit, which holds correspondence relations that replicate the data association capability without physically adding connection keys to external data. This allows the system to acquire data as if connection keys existed, while working with the original external data structure.

Inventive Principle:

Principle #26Copying

3Reliability

If connection keys are used to associate site data with external data, then data association is achieved, but external data without connection keys cannot be utilized

Engineering Contradiction:

Improvedata association accuracyVSAvoiddata source compatibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the parameter of data association from requiring exact matching connection keys to using flexible correspondence relations defined in the link logic definition unit. This allows the system to associate external data with site data through multiple possible parameters and relationships, maintaining association accuracy while greatly increasing compatibility with different external data sources.

AI summary

Provided is an information system and an information collection method that are capable of acquiring desired site data while preventing an increase in cost. A link logic definition unit 17 holds a link logic that is definition information defining a correspondence relation between an item value of the site data and a reference value that is an external value of transaction data used for acquiring the item value. A link logic data acquisition unit 18 acquires the item value of the site data by using the link logic.
