Solution Overview

Problem

Current systems for operating printing presses require operators to physically interact with control stations, limiting ergonomic freedom and efficiency, as they often rely on two-dimensional gesture recognition and touchscreens that restrict movement and context-sensitive input.

Innovation Solution

A 3D gesture detection system that allows contactless control of a large-screen monitor, enabling operators to generate control signals using hand and finger movements, allowing for intuitive operation from a distance without direct contact, and providing ergonomic flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If operators physically interact with control stations using traditional interfaces, then control functions can be executed, but operator mobility is restricted and ergonomic freedom is limited

Engineering Contradiction:
Improveoperator mobilityVSAvoidcontrol system structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent replaces mechanical interaction with control panels (buttons, touchscreens, physical interfaces) with a gesture-based optical detection system. The 3D detection device captures hand and finger movements in three-dimensional space, converting physical gestures into control signals without requiring physical contact with the control station. This substitution eliminates the need for operators to be positioned at fixed control interfaces, thereby improving mobility while maintaining full control functionality.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a 3D detection device as an intermediary between the operator and the control system. This device captures gesture data in three-dimensional space and translates it into control commands, serving as a mediator that enables contactless interaction. The intermediary layer allows operators to control the printing press from various positions and distances, freeing them from the constraint of fixed control station locations.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If two-dimensional gesture recognition is used, then control input is simplified, but context-sensitive input and intuitive operation are restricted

Engineering Contradiction:
Improvegesture control flexibilityVSAvoidgesture detection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent transitions from two-dimensional gesture recognition to three-dimensional gesture detection. The 3D detection device captures hand and finger movements in three-dimensional space, adding depth information to the gesture data. This dimensional enhancement enables more intuitive and context-sensitive control, as operators can perform natural hand gestures in space without being constrained to a flat interaction plane. The additional spatial dimension improves both gesture flexibility and detection precision.

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

3Productivity

If operators must go to the press control station area to check and correct data, then data accuracy can be verified, but time is lost and efficiency is reduced

Engineering Contradiction:
Improveoperational efficiencyVSAvoidtime to access control data
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent enables operators to access and control printing press functions directly from their working position without needing to physically move to the control station. The gesture-based control system brings the control interface to the operator, allowing them to verify and correct data, adjust settings, and monitor operations while remaining at the printing press. This self-service capability eliminates unnecessary movement and time loss, thereby improving operational efficiency.

Inventive Principle:
Principle #25Self-service

4Reliability

If contactless gesture control is implemented, then operator safety is improved and unintentional inputs are reduced, but system complexity increases

Engineering Contradiction:
Improveinput accuracyVSAvoiddetection system structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces physical contact-based control interfaces with a gesture-based optical detection system. This substitution eliminates the risk of unintentional inputs that can occur with touchscreens or physical buttons, as gestures require deliberate hand movements that are easier to control intentionally. The 3D detection system captures and interprets these gestures, providing reliable and accurate input while improving operator safety by removing the need for physical contact with control surfaces.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A system for printing press operation of a printing press, in particular a sheet-fed printing press, which system interacts with a printing press control desk (17) and a plurality of control-side modules (16) which are arranged distributed in the printing press, is to be designed so as to be simpler to operate. To this end, at least one 3D sensor (20) which reacts to gestures is assigned to the printing press control desk (17) or is arranged in the operating region of the printing press control desk (17), wherein it can be activated by persons working on the printing press. Data/control signals for operating the printing press are generated and/or transmitted by means of the 3D sensor (20).
