Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic labels face high manufacturing costs and inflexibility in displaying content, particularly when multiple display screens are required to show different or the same information simultaneously, lacking a cost-effective and flexible solution for updating and diversifying display content.
Innovation Solution
An electronic label system comprising multiple display screens, a repeater, a communicator, and a controller with a serial data interface that allows for synchronized data transmission and control signals to be sent to each screen, enabling flexible content display by selecting and encoding signals for multiple screens through fewer interfaces, reducing manufacturing costs and enhancing operational flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display screens are used to show different content simultaneously, then display flexibility and information diversity are improved, but manufacturing cost increases
Solution Approach 1:
The patent merges multiple display screens into a single electronic label device, allowing multiple screens to be controlled by a unified controller that manages content distribution through a centralized communication module, reducing overall system complexity and manufacturing cost while maintaining display flexibility
Solution Approach 2:
The controller is designed with multi-functionality to handle content management for multiple display screens, enabling a single controller to selectively address and update different screens based on content requirements, thereby reducing the need for separate controllers for each screen
2Ease of operation
If individual control interfaces are provided for each display screen, then control precision and content updates are improved, but device complexity increases
Solution Approach 1:
A single communication interface is designed with multi-functional capability to control multiple display screens. The interface can selectively communicate with different screens based on content requirements, eliminating the need for separate dedicated interfaces for each screen while maintaining precise control
Solution Approach 2:
The patent introduces a communication module as an intermediary between the controller and multiple display screens. This module manages the distribution of control signals and content data to appropriate screens, simplifying the overall interface structure while enabling precise individual screen control
3Use of energy by moving object
If sequential content updates are implemented across multiple screens, then energy consumption is reduced, but update time and information latency increase
Solution Approach 1:
The patent implements dynamic content update strategies where the system can adaptively choose between sequential and parallel update modes based on content characteristics and user requirements. The controller dynamically adjusts update timing and methodology to balance energy consumption with information freshness
Solution Approach 2:
The system employs periodic content updates with flexible timing mechanisms. The communication module can schedule content transmission at optimal intervals, allowing sequential updates to reduce energy consumption while maintaining acceptable information latency through intelligent timing rather than immediate continuous updates
