Solution Overview

Problem

Existing image forming systems face disruptions when events like staple exhaustion occur during binding processing, necessitating a stop until the issue is resolved, which interrupts the workflow.

Innovation Solution

The system switches automatically from staple processing to stapleless processing, and if necessary, reverses the discharge order and binding positions of paper bundles to continue the binding process without manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If staple processing is selected for binding processing, then binding strength is improved, but processing stops when staple exhaustion occurs

Engineering Contradiction:
Improvebinding strengthVSAvoidprocessing continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system dynamically changes the binding method parameter from staple processing to stapleless processing when staple exhaustion is detected. The control unit monitors staple consumption and automatically switches to an alternative binding method (stapleless binding) to maintain processing continuity without manual intervention, thus resolving the contradiction between binding strength and processing continuity.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system performs self-diagnosis and self-correction by automatically detecting staple exhaustion and switching to stapleless binding without requiring operator intervention. This self-service mechanism ensures continuous processing while maintaining reliable binding results, eliminating the need for manual staple replenishment or system shutdown.

Inventive Principle:
Principle #25Self-service

2Reliability

If binding processing is stopped to resolve events like staple exhaustion, then binding quality is maintained, but workflow efficiency deteriorates

Engineering Contradiction:
Improvebinding qualityVSAvoidworkflow interruption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system ensures continuous binding processing by automatically switching between staple and stapleless binding methods. When staple exhaustion is detected, the control unit seamlessly transitions to stapleless binding, maintaining uninterrupted workflow and eliminating idle time while preserving binding quality through automated method selection.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The control unit performs preliminary monitoring of staple consumption levels and proactively switches to stapleless binding before complete staple exhaustion occurs. This preliminary action prevents processing interruptions and maintains continuous workflow, thereby reducing time loss while ensuring consistent binding quality.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If automatic switching between binding methods is implemented, then processing continuity is improved, but system complexity increases

Engineering Contradiction:
Improveprocessing continuityVSAvoidcontrol mechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The binding processing unit is designed with multi-functionality to perform both staple and stapleless binding methods using the same hardware platform. The control unit selectively activates the appropriate binding method based on staple availability, eliminating the need for separate dedicated systems and reducing overall device complexity while maintaining processing continuity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system implements a feedback mechanism where the control unit monitors staple consumption levels and automatically adjusts the binding method accordingly. This simple feedback loop (detect staple level → switch method if needed) achieves processing continuity through minimal control logic, avoiding excessive system complexity.

Inventive Principle:
Principle #23Feedback

4Reliability

If discharge order and binding positions are switched after method change, then binding consistency is improved, but processing complexity increases

Engineering Contradiction:
Improvebinding consistencyVSAvoiddischarge control complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

When switching from staple to stapleless binding, the system inverts the discharge order and binding positions to compensate for differences in binding mechanics. This inversion ensures that the final bound product maintains consistent orientation and quality regardless of the binding method used, achieving binding consistency through simple order reversal rather than complex real-time adjustments.

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

An image forming system (1) includes one or plural processors (11). The one or plural processors are configured to cause binding processing of binding plural sheets of paper to create a paper bundle (B) to be performed by selected one of the binding processing of staple processing using a staple and stapleless processing without using the staple, and perform, in a case where a predetermined event occurs in creating the paper bundle, first switching processing of switching the binding processing to the other binding processing.
