Solution Overview

Problem

Existing printing technologies require separate issuance of single-sided and double-sided printing tasks, leading to a cumbersome and time-consuming process for documents with mixed printing requirements, such as textbooks where the table of contents and cover are printed on one side and the main text on two sides.

Innovation Solution

A single-sided and double-sided mixed printing method that determines the printing mode and position of each page based on user configuration, allowing simultaneous single-sided and double-sided printing without manual page reordering, using an image forming device with modules to determine and execute these settings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate single-sided and double-sided printing tasks are issued, then printing requirements for different pages can be met, but the printing process becomes cumbersome and time-consuming

Engineering Contradiction:
Improveprinting mode flexibilityVSAvoidprinting process complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent segments the printing task by identifying different page types (cover, table of contents, main text) and assigning appropriate printing modes (single-sided or double-sided) to each segment. The system divides the document into multiple to-be-printed pages with different printing requirements and processes them independently according to their specific needs.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic printing mode selection where the printing mode (single-sided or double-sided) is determined dynamically for each page based on its type and position in the document. The system automatically adjusts printing parameters for each page without requiring manual reconfiguration, making the printing process adaptive rather than static.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If manual page reordering is performed after printing, then correct page sequence is achieved, but printing efficiency is reduced

Engineering Contradiction:
Improvepage sequence accuracyVSAvoidprinting efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent performs preliminary actions by determining the printing mode and position for each page before the actual printing process. The system pre-calculates the optimal printing sequence and assigns printing parameters in advance, so that pages are printed in the correct order from the start, eliminating the need for post-printing reordering operations.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The printing system automatically manages the page sequencing and printing mode selection without requiring manual intervention. The device serves itself by intelligently determining which pages should be printed on which side and in what order, based on the document structure and printing requirements, thereby maintaining high printing efficiency while ensuring correct page sequence.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If multiple separate printing tasks are issued, then comprehensive printing requirements are met, but toner consumption increases

Engineering Contradiction:
Improveprinting requirement coverageVSAvoidtoner consumption
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The patent merges multiple separate printing tasks into a single integrated printing process. Instead of issuing separate single-sided and double-sided printing tasks, the system combines them into one unified task that processes all pages in sequence, determining the appropriate printing mode for each page dynamically. This consolidation reduces redundant operations and minimizes toner consumption while still meeting all printing requirements.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The disclosure relates to a single-sided and double-sided mixed printing method and related devices. The method includes determining a printing mode of a first to-be-printed page currently to be printed, where the printing mode includes a single-sided printing or a double-sided printing; when the printing mode of the first to-be-printed page is the single-sided printing, determining a printing position of the first to-be-printed page, where the printing position includes on a front side of a paper or a back side of the paper; and printing out the first to-be-printed page based on the printing position, where the printing out includes a single-sided printout or a double-sided printout.
