Equipment Management Server Demand-Driven Listing

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing auction processing device cannot prompt listing of equipment for sale on a secondhand products trading market unless it matches both the 'purchases list' and 'favorites list', thereby failing to promote the transaction of unused equipment.

Innovation Solution

An equipment management server that acquires equipment information from user terminals, determines demand in the secondhand market based on transaction results, and transmits listing solicitation notices to the terminals, regardless of list matching, to encourage listing on the secondhand market.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the auction server only transmits listing notices when equipment matches both 'purchases list' and 'favorites list', then the system maintains precise matching accuracy, but the transaction promotion coverage is limited

Engineering Contradiction:

Improvematching accuracyVSAvoidtransaction promotion coverage

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The notification system is segmented into two independent channels: one for matched equipment (favorites list matching) and another for demand-driven equipment (transaction result-based). This allows the system to maintain precise matching for some equipment while simultaneously expanding coverage to additional equipment based on market demand, resolving the contradiction between accuracy and coverage

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The equipment management server is enhanced to perform multiple functions: it continues to process favorites list matching while simultaneously analyzing transaction results and independently generating listing notices for high-demand equipment. This multi-functionality enables the system to serve both precise matching needs and broader transaction promotion goals

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Productivity

If the system expands listing notice transmission to all equipment on 'purchases list' regardless of list matching, then the transaction promotion coverage increases, but the system complexity increases

Engineering Contradiction:

Improvetransaction promotion coverageVSAvoidsystem complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The equipment management server acts as an intermediary that analyzes transaction results from the secondhand market and uses this information to generate listing notices. This intermediary approach adds minimal complexity by leveraging existing transaction data and simple analysis logic, rather than requiring complex matching algorithms, thus expanding coverage while maintaining system simplicity

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An equipment management server includes: an equipment information acquiring unit that acquires, from a first terminal device that registers equipment owned by a user, equipment information indicating the equipment; a demand determination unit that acquires the transaction result of the equipment indicated by the equipment information acquired by the equipment information acquiring unit in a secondhand products trading market, and determines whether or not there is a demand for the equipment in the secondhand products trading market on the basis of the transaction result; and a solicitation notice transmitting unit that transmits, to the first terminal device, a listing solicitation notice prompting listing of the equipment on the secondhand products trading market when the demand determination unit determines that there is a demand.
