Solution Overview

Problem

Existing labeling systems face inaccuracies in applying labels to goods due to lack of precise position detection, insufficient mechanical contact, and throughput limitations, particularly in the postal sector.

Innovation Solution

A labeling device with a movable arm that applies labels through contact, allowing synchronous tracking and adaptation to goods' movements, using a functional end with suction grippers and elastic elements to ensure secure attachment, and a control unit for precise application.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If compressed air is used to apply labels without mechanical contact, then the piece of goods can be handled without damage, but the label application precision and adhesion are insufficient

Engineering Contradiction:
Improvedamage to piece of goodsVSAvoidlabel application precision
Core Design Contradiction:
Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent changes the fundamental parameter of label application from contactless pneumatic application to controlled mechanical contact. The movable arm applies direct mechanical contact to press the label firmly onto the piece of goods, while the elastic element ensures gentle contact that adapts to the goods surface, preventing damage while achieving precise label adhesion.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The elastic element acts as an intermediary between the movable arm and the piece of goods. It transmits the pressing force from the movable arm while cushioning the impact and adapting to the goods surface, thus preventing damage during the label application process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If simple light barriers are used to detect piece of goods positions, then the detection system is simple, but the measurement precision and positioning accuracy are insufficient

Engineering Contradiction:
Improvedetection system complexityVSAvoidposition detection precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent replaces simple optical light barriers with a movable arm system that physically tracks and follows the piece of goods. The movable arm is positioned and controlled based on the goods location, enabling precise measurement and positioning through mechanical tracking rather than simple optical detection.

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

3Productivity

If conventional labeling systems are used, then the basic labeling function is provided, but the throughput is not adapted to modern handling device requirements

Engineering Contradiction:
Improvethroughput rateVSAvoidadaptability to handling devices
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a movable arm that can dynamically adjust its position, speed, and movement trajectory to match the handling device's throughput requirements. The movable arm synchronizes its operations with the piece of goods movement, enabling high-speed label application that adapts to various handling device speeds and rhythms, thereby increasing overall throughput.

Inventive Principle:
Principle #15Dynamics
