Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic paper labels require multiple flashes to update display frames, leading to a prolonged update time of over 10 seconds with no display effect, causing inconvenience and increased labor costs.

Innovation Solution

A serial electronic label design with a controller managing a sequence of energy-saving displays, where adjacent displays' frame update times partially overlap, allowing for a marquee-like display effect and reducing labor costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If electronic paper is used for electronic labels with three colors or more, then the display capability is improved, but the update time exceeds 10 seconds causing no display effect during waiting

Engineering Contradiction:

Improvedisplay capabilityVSAvoidupdate time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The electronic label is divided into multiple independent display units (first display unit, second display unit, third display unit) arranged in sequence. Each unit can update its display frame independently and simultaneously, allowing the system to achieve full-color display capability while reducing the perceived update time through parallel operation and visual persistence effects.

Inventive Principle:

Principle #1Segmentation

2Reliability

If multiple flashes are required to update display frames on electronic paper, then the correct frame can be displayed, but the update process takes more than 10 seconds with no display effect during waiting

Engineering Contradiction:

Improveframe accuracyVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements continuous display action by having multiple display units update in sequence with overlapping time intervals. The first display unit updates during the second display unit's display period, and so on, creating a continuous visual output that eliminates blank periods and maintains user engagement throughout the update process.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If traditional paper labels are replaced with electronic labels, then real-time updates can be achieved, but the labor cost of replacing labels increases due to manual intervention requirements

Engineering Contradiction:

Improvereal-time update capabilityVSAvoidlabor cost

Core Design Contradiction:

ProductivityVSEase of manufacture

Solution Approach 1:

The electronic label system enables self-service operation where display content is updated automatically through electrical signals from a control device. The multiple display units can be updated sequentially or in parallel without requiring manual physical replacement, eliminating labor costs associated with traditional paper label changes while maintaining real-time update capabilities.

Inventive Principle:

Principle #25Self-service

AI summary

A serial electronic label, including a plurality of energy saving displays arranged in a row and a controller. Each of the energy saving displays has a frame update time when updating a display frame. The controller is electrically connected to the energy saving displays, and configured to make the energy saving displays update the display frames thereof in a sequence by a one-to-plurality control method, wherein the frame update times of any two energy saving displays adjacent in the sequence partially overlap each other.
