Dual Communication Paths for Image Forming System Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of third-party sheet processing apparatuses with image forming systems is hindered by communication protocol limitations, leading to restricted functionality and operational constraints, as existing methods often require serial communication for detailed information transfer and cannot handle the full range of data needed for seamless operation between different apparatuses from various manufacturers.
Innovation Solution
The implementation of an image forming system with dual communication paths – an exclusive path for fixed communication between specific apparatuses and a general-purpose path for flexible communication between upstream and downstream apparatuses, allowing for the transmission of necessary information without operational restrictions, even when apparatuses from different manufacturers are connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If serial communication is used to transmit detailed information between apparatuses, then information transmission capability is improved, but device complexity increases due to protocol requirements
Solution Approach 1:
The communication system is divided into two independent paths: a serial communication path for detailed information transmission and a parallel communication path for basic control signals. This segmentation allows each path to serve its specific purpose without imposing protocol complexity on the entire system, resolving the contradiction between information transmission capability and device complexity.
Solution Approach 2:
The parallel communication path is designed to handle multiple communication needs (apparatus selection, basic control) through a single interface, making it universal. This multi-functionality reduces the need for separate dedicated interfaces for each communication task, thereby reducing overall device complexity while maintaining information transmission capabilities.
2Adaptability or versatility
If third-party sheet processing apparatuses are connected to the image forming system, then adaptability is improved, but operational restrictions increase due to communication protocol limitations
Solution Approach 1:
The parallel communication path acts as an intermediary layer that simplifies communication between the image forming apparatus and third-party sheet processing apparatuses. By providing a standardized, manufacturer-independent interface for basic control and apparatus selection, it eliminates operational restrictions imposed by manufacturer-specific serial protocols, thereby improving adaptability while maintaining ease of operation.
3Productivity
If high-speed serial communication is used to transmit massive data, then productivity is improved, but device complexity increases
Solution Approach 1:
The communication system segments data transmission into two paths: serial communication for high-speed massive data transfer and parallel communication for lightweight control signals. This segmentation allows the system to achieve high productivity through serial communication while keeping the overall device complexity manageable by using simpler parallel communication for routine control tasks.

AI summary
An image forming system includes an upstream apparatus for forming an image on a sheet, a downstream apparatus for applying sheet processing to the sheet on which the image is formed by the upstream apparatus, an exclusive communication path for communicating information which is necessary only for an operation of each apparatus in a state in which a communication partner is fixed between the upstream apparatus and the downstream apparatus, and a general-purpose communication path for communicating information in a state in which a communication partner is selectable between the upstream apparatus and the downstream apparatus. The exclusive communication path and the general-purpose communication path communicate information which respective paths can handle by sharing the information with each other.
