Solution Overview

Problem

Users find it difficult to designate appropriate paper types for printing due to the numerous available types, such as glossy, matte, and high-class photographic papers, which can lead to complicated settings and inappropriate printing.

Innovation Solution

A printing system that communicates with a terminal apparatus to store and display selectable paper types, allowing users to select a paper type category on the terminal, which corresponds to the paper type set in the printing apparatus, ensuring appropriate printing based on the paper's attributes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the printing apparatus registers multiple specific paper types (glossy, matte, silky, high-class, cheap), then the printing quality can be optimized for each paper type, but the user interface becomes complex and difficult to operate

Engineering Contradiction:
Improveprinting qualityVSAvoiduser interface complexity
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The patent segments the numerous specific paper types into broader categories (photographic paper, plain paper, specialty paper) that users can easily understand and select. This categorization maintains the ability to optimize printing for specific paper types while simplifying the user interface to only display high-level categories rather than listing every specific paper type available.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary mapping system between user-selected categories and the actual specific paper types registered in the printing apparatus. When a user selects a category, the system automatically maps it to the appropriate specific paper type based on the paper set in the apparatus, eliminating the need for users to directly select from complex lists of specific paper types while still achieving optimal printing settings.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If the terminal apparatus displays all available specific paper types, then users can make precise selections, but the number of options becomes overwhelming and selection becomes difficult

Engineering Contradiction:
Improvepaper type selection accuracyVSAvoidnumber of selection options
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the complete list of specific paper types into hierarchical categories. The terminal apparatus displays only the top-level categories (photographic paper, plain paper, specialty paper) to users, reducing the apparent number of options from dozens of specific types to just a few broad categories. The specific paper type information is retained in the system but not directly exposed to users for selection.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds a categorical dimension to the paper type selection interface. Instead of presenting a flat list of all specific paper types, the system organizes them into a hierarchical structure where users first select a category and then the system automatically determines the specific paper type based on the physical paper detected in the printing apparatus, effectively adding an organizational layer that reduces complexity.

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

3Reliability

If the system requires users to manually select specific paper types, then printing settings can be precisely matched, but the user burden increases and operation becomes time-consuming

Engineering Contradiction:
Improvesetting accuracyVSAvoidselection time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent enables the system to automatically determine the appropriate specific paper type by detecting the physical paper properties (through sensors or user input of paper characteristics) and matching them with the registered paper types in the printing apparatus. This self-service approach eliminates the need for users to manually search through and select specific paper types, while the system automatically ensures accurate matching between the selected category and the actual paper being used.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent performs preliminary registration of all specific paper types and their corresponding categories in the printing apparatus before the user needs to make a selection. This pre-configuration allows the system to quickly and automatically match user-selected categories with the correct specific paper types and printing settings, eliminating the time-consuming process of manual selection while maintaining accurate setting matching.

Inventive Principle:
Principle #10Preliminary action

AI summary

A printing apparatus to communicate with a terminal apparatus, includes a storing unit, an acquiring unit, a receiving unit, and a printing unit. The storing unit stores information for specifying first paper types selectable in the terminal apparatus. The terminal apparatus acquires the information from the printing apparatus and displays the first paper types as selection candidate paper types. The acquiring unit acquires a second paper type. The receiving unit receives a first paper type from the first paper types for printing of an image. The printing unit prints the image where the first paper type corresponding to second paper types is received and any of the second paper types corresponding to the first paper type is acquired, and does not print the image where the first paper type corresponding to second paper types is received and another second paper type different from the second paper types is acquired.
