Solution Overview

Problem

In image forming apparatuses, especially in POD environments, selecting the appropriate paper feed tray from multiple trays is cumbersome due to poor viewability and time-consuming processes, particularly when numerous paper types are available, leading to inefficiencies in operation.

Innovation Solution

The implementation of an improved paper selection system that dynamically adjusts the display of paper feed deck information, allowing users to select paper based on automatic or manual modes, with optimized screen transitions and display management tables to prioritize paper types and sizes, enabling quick identification of desired paper without extensive paging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If paper feed tray information is displayed in list format with detailed information, then complete information about all paper feed trays can be shown, but the number of screens required increases and user operation time increases

Engineering Contradiction:
Improvepaper feed tray information completenessVSAvoiduser operation time
Core Design Contradiction:
Loss of informationVSLoss of time

Solution Approach 1:

The paper feed tray information is segmented into multiple categories (paper size, paper type, grammage) and displayed in a tabular format with columns for each category. This allows all information to be visible simultaneously on a single screen without requiring pagination, resolving the contradiction between information completeness and operation time.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The information display transitions from a vertical list format requiring multiple screens to a horizontal tabular format that fits all information on one screen. By reorganizing the data structure from sequential to matrix-based, all paper feed tray information becomes accessible in a single view, eliminating the need for paging operations.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If paper feed tray information is displayed in list format, then all paper types can be shown, but viewability and ease of selection deteriorate due to required paging and scrolling

Engineering Contradiction:
Improvepaper type information completenessVSAvoidpaper feed tray selection ease
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The display is segmented into a table structure with distinct columns for paper size, paper type, and grammage. This segmentation allows users to quickly scan and compare different paper feed trays across multiple attributes simultaneously, improving ease of operation while maintaining complete information visibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs visual indicators such as icons and highlighted text to represent different paper types and states. These visual cues enable users to quickly identify and distinguish between various paper feed trays without requiring detailed reading, thereby improving ease of operation while displaying complete information.

Inventive Principle:
Principle #32Color changes

3Adaptability or versatility

If the number of paper feed trays is increased to accommodate various paper types, then paper type versatility improves, but the complexity of paper selection increases

Engineering Contradiction:
Improvepaper type varietyVSAvoidpaper selection process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The paper feed tray information is organized into a segmented table format with columns for paper size, paper type, and grammage. This structured segmentation allows users to quickly locate and identify the desired paper feed tray among many options by scanning specific columns, thereby reducing selection complexity while maintaining high paper type versatility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The table-based display system serves multiple functions simultaneously: it displays complete information about all paper feed trays, enables quick visual comparison of different paper types, and provides intuitive selection capability. This multi-functional approach handles high paper type variety without increasing selection complexity.

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