Solution Overview

Problem

Existing shelf label printers are limited by fixed label lengths, requiring separate printers and label sheets for different lengths and types, leading to inefficiencies in merchandise information display and price reduction indications, and necessitating multiple sheet types for varying display spaces.

Innovation Solution

A shelf label printer and method that uses a continuous strip-form label sheet with perforations and position detecting marks, allowing for arbitrary length formation and printing of merchandise information, enabling flexible label lengths and shared sheet material for price reduction labels, eliminating the need for multiple sheet types and printers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed length shelf labels are used, then the label structure is simple, but the adaptability to different display spaces and merchandise volumes is poor

Engineering Contradiction:
Improveadaptability to different display spacesVSAvoidlabel sheet variety
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal label sheet that can serve multiple functions by accommodating shelf labels of different lengths (short, medium, long) and price reduction labels on a single continuous sheet. The label printer is designed to handle this multi-functional sheet, eliminating the need for separate printers and sheet types for different label configurations.

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

Solution Approach 2:

The continuous label sheet is divided into multiple independent label regions of different lengths, each separable by perforations. This segmentation allows the system to produce various label lengths from a single unified sheet structure, enabling flexible adaptation to different display spaces while maintaining a simple, unified sheet design.

Inventive Principle:
Principle #1Segmentation

2Productivity

If separate printers and label sheets are used for different label types, then the printing function is specialized, but the operational complexity and time consumption increase

Engineering Contradiction:
Improveprinting efficiencyVSAvoidoperational complexity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent merges the printing functions for different label types (shelf labels and price reduction labels) into a single integrated printing operation. The label printer handles both long shelf labels and short price reduction labels on the same continuous sheet, eliminating the need for separate printers and reducing operational steps.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The label printer is designed as a universal device capable of printing various label types and lengths from a single sheet. This multi-functional approach consolidates what would otherwise require multiple specialized printers, improving productivity while simplifying operation.

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

3Adaptability or versatility

If multiple label sheet types are prepared, then the label length requirement is met, but the inventory management and cost increase

Engineering Contradiction:
Improvelabel length flexibilityVSAvoidsheet inventory
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The continuous label sheet serves as a universal inventory that can produce labels of various lengths through its segmented design. By maintaining only one type of sheet inventory instead of multiple specialized sheets, the system reduces stock complexity and costs while still meeting diverse label length requirements.

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

Solution Approach 2:

The single continuous sheet is segmented into multiple usable label regions of different lengths. This segmentation allows the system to fulfill various label length requirements from a single sheet type, eliminating the need to maintain inventory for multiple different sheet lengths.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If the label sheet is continuous, then the printing operation is simplified, but the position detection accuracy may be affected

Engineering Contradiction:
Improveprinting operation simplicityVSAvoidposition detection accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

Position detecting marks are introduced as intermediary elements on the continuous label sheet to provide reliable position information to the label printer. These marks act as reference points that enable accurate position detection despite the continuous nature of the sheet, ensuring precise label placement while maintaining printing simplicity.

Inventive Principle:
Principle #24Intermediary (Mediator)
