Solution Overview
Problem
Conventional image forming systems fail to efficiently manage the increased complexity and diversity of combinations between image forming apparatuses and post-finishing apparatuses, leading to inadequate handling of various operational jobs and limited improvement in printing productivity.
Innovation Solution
A sheet conveyance relay unit with a convergence unit to collect sheets from multiple image forming apparatuses, a common sheet-conveyance section to direct them to a shared outlet, and a divergence unit to distribute the sheets to multiple post-finishing apparatuses, along with a control section that selects appropriate apparatuses based on job information for efficient processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple image forming apparatuses and post-finishing apparatuses are combined in conventional systems, then the number of combinations increases to meet diverse user needs, but the system fails to efficiently manage the increased complexity and diversity of combinations
Solution Approach 1:
A relay unit is introduced as an intermediary component between image forming apparatuses and post-finishing apparatuses. The relay unit includes a convergence unit that receives sheets from multiple image forming apparatuses and a divergence unit that distributes sheets to multiple post-finishing apparatuses. This intermediary structure manages the complexity of multiple combinations by centralizing sheet routing control, allowing flexible adaptation to diverse user needs without proportionally increasing system complexity.
2Adaptability or versatility
If conventional systems handle various operational jobs with multiple apparatuses, then more job types can be supported, but printing productivity improvement is limited
Solution Approach 1:
The relay unit enables continuous sheet conveyance from image forming apparatuses through the convergence unit and divergence unit to post-finishing apparatuses. The control unit coordinates sheet flow to maintain continuous operation across multiple apparatuses, preventing idle time and bottlenecks. This continuous action approach supports diverse job types while improving overall printing productivity by ensuring that sheets move continuously through the system without unnecessary stops or waiting.
3Device complexity
If a single post-finishing apparatus is combined to a single image forming apparatus in conventional systems, then the system structure is simple, but it cannot meet diversified user needs
Solution Approach 1:
The relay unit serves multiple functions: it acts as a convergence point for sheets from multiple image forming apparatuses, provides routing control to direct sheets to appropriate post-finishing apparatuses, and enables flexible combination of multiple apparatuses. This multi-functional design allows a single relay unit to replace multiple dedicated connections, maintaining relative structural simplicity while significantly increasing adaptability to diversified user needs.
