Solution Overview

Problem

Current methods for adjusting the position of elements on bar-shaped electronic shelf labels require the installation of a touch bar, leading to poor accuracy, complex design, and high costs due to contact jitter and accuracy drift during sliding operations.

Innovation Solution

A method and device that utilize a mobile terminal to couple with the electronic shelf label, obtain status information, change the position of display elements, and generate adjustment instructions, eliminating the need for a touch bar and improving accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a touch bar is installed under the electronic shelf label to enable element position adjustment, then the adjustment function is achieved, but the device complexity and cost increase

Engineering Contradiction:

Improveelement position adjustmentVSAvoidtouch bar installation

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts the touch bar component from the electronic shelf label system, moving the adjustment functionality to an external mobile terminal. This eliminates the need for integrated touch bar hardware under the label, reducing device complexity while maintaining adjustment capability through wireless communication between the mobile terminal and the electronic shelf label.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The mobile terminal is utilized as a multi-functional device that both displays and controls the electronic shelf label. By leveraging the mobile terminal's existing touch interface and processing capabilities, the system achieves element position adjustment without requiring dedicated adjustment hardware in the label itself.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If a touch bar is used for element position adjustment, then adjustment capability is provided, but measurement precision deteriorates due to contact jitter and accuracy drift

Engineering Contradiction:

Improveelement position adjustmentVSAvoidposition adjustment accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent introduces wireless communication as an intermediary between the mobile terminal and electronic shelf label, replacing direct physical contact through the touch bar. This intermediary layer transmits position adjustment data without the mechanical contact jitter and accuracy drift inherent in sliding touch operations, significantly improving measurement precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical sliding touch operation with a digital data transmission mechanism. Instead of physically sliding a finger along the touch bar, the user interacts with a virtual interface on the mobile terminal, and the position adjustment is transmitted wirelessly, eliminating mechanical errors entirely.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a touch bar is installed for adjustment functionality, then element repositioning is enabled, but manufacturing cost increases

Engineering Contradiction:

Improveelement position adjustmentVSAvoidproduction cost

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

By extracting the touch bar component from the electronic shelf label assembly, the patent eliminates the need for precision manufacturing and assembly of touch bar components. The mobile terminal, which already possesses touch interface capabilities, assumes this function, thereby reducing manufacturing complexity and cost for the electronic shelf label.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a virtual copy of the touch bar interface on the mobile terminal's display. Instead of manufacturing a physical touch bar, the system replicates the adjustment functionality through software-based touch controls on the mobile device, significantly reducing hardware manufacturing costs.

Inventive Principle:

Principle #26Copying
