Solution Overview

Problem

Existing image forming systems using wireless communication struggle to identify the physical arrangement order of processing apparatuses, leading to inefficiencies in cooperation and potential delays in sheet conveyance and processing.

Innovation Solution

An image forming system that includes an image forming apparatus, multiple accessory apparatuses, and a base station for wireless communication, where the image forming apparatus acquires information on the arrangement order of accessory apparatuses through the base station and displays this information to the user for registration, utilizing the Fifth Generation Mobile Communication System (5G) for low-delay communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communication is used instead of wired communication, then the change and relocation of optional apparatuses becomes easier, but the ability to identify the physical arrangement order of apparatuses is lost

Engineering Contradiction:
Improvechange and relocation of optional apparatusesVSAvoidphysical arrangement order information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent introduces a base station as an intermediary device that mediates communication between the image forming apparatus and multiple optional apparatuses. The base station receives wireless signals from optional apparatuses, extracts their identification information, and transmits this information to the image forming apparatus. This intermediary solution enables wireless communication while preserving the ability to identify the physical arrangement order of apparatuses, thus resolving the contradiction between wireless adaptability and information retention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If wireless communication is used for cooperation among apparatuses, then cable connections are eliminated, but sufficient information acquisition for cooperation cannot be achieved

Engineering Contradiction:
Improvecooperation among apparatusesVSAvoidinformation required for cooperation
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The base station serves as a communication intermediary that collects identification information from multiple optional apparatuses via wireless communication and transmits this information to the image forming apparatus. This enables the image forming apparatus to acquire necessary cooperation information wirelessly, maintaining ease of operation while preventing information loss.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical cable connection system with a wireless communication system. Instead of physically connecting apparatuses via cables to exchange information, the system uses wireless signals transmitted through the base station to convey identification and arrangement information, thereby eliminating mechanical connections while preserving information exchange capabilities.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
