Solution Overview

Problem

Output devices with post-processing apparatuses like staplers face reduced durability due to improper use, such as stapling beyond specified limits, leading to potential failures and operator dissatisfaction.

Innovation Solution

An output device and system that adjusts print settings to minimize the load on the stapler by changing sheet orientation or rotating image data, reducing the moving range of the stapler, thus preventing durability degradation without imposing uniform restrictions on operators.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the stapler is designed to satisfy a certain degree of durability, then the device can handle specified number of sheets, but the durability is reduced when operators instruct the stapler to staple output products whose number exceeds the specified number of sheets

Engineering Contradiction:
Improvestapler durabilityVSAvoidflexibility in handling different sheet quantities
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically changes processing parameters (sheet orientation, image rotation) based on the number of sheets to be stapled. When the sheet count exceeds a threshold, the system automatically adjusts these parameters to reduce stapler load, thereby maintaining durability while still allowing operation on larger quantities of sheets.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The stapler system transitions from a static design with fixed durability limits to a dynamic system that adapts its operation based on real-time conditions (number of sheets). By dynamically adjusting processing settings, the system optimizes the balance between handling capacity and durability preservation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If techniques restrict the use of the stapler to preserve durability, then the stapler longevity is improved, but operator convenience and productivity are reduced

Engineering Contradiction:
Improvestapler longevityVSAvoidoutput processing efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs self-adjustment by automatically changing processing settings (orientation, rotation) based on the detected number of sheets. This eliminates the need for external restrictions or operator intervention, allowing the stapler to protect itself while maintaining normal productivity levels.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system proactively adjusts processing parameters before the durability threshold is exceeded. By predicting when restrictions might be needed and preemptively optimizing settings, the system prevents durability degradation while avoiding the need for reactive restrictions that would impact productivity.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If the stapler moving range is reduced by changing sheet orientation or rotating image data, then the stapler durability is enhanced, but the complexity of the output device increases

Engineering Contradiction:
Improvestapler durabilityVSAvoidoutput device control complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The output device leverages existing multi-functional capabilities (image rotation, orientation adjustment) already present in modern printing systems. By utilizing these existing functions for the new purpose of stapler protection, the system avoids adding significant complexity while achieving durability enhancement.

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