Innovation Solution

An electronic shelf label information processing system that includes an access point, an electronic shelf label, and a remote controller, utilizing a 2.4G wireless communication protocol for bidirectional data interaction, allowing the remote controller to acquire and transmit information to the access point and background server, enabling real-time updates and management of display information, inventory, and price modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the remote controller uses only infrared transmission to control the electronic shelf label, then the control function is simple and reliable, but bidirectional data interaction between the remote controller and the electronic shelf label cannot be achieved

Engineering Contradiction:
Improvedata interaction capabilityVSAvoidcommunication system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The remote controller is designed to support multiple communication protocols (infrared and 2.4G wireless) within a single device, enabling it to perform both traditional control functions and new data interaction functions. The electronic shelf label similarly integrates both infrared reception and 2.4G communication capabilities, allowing it to respond to traditional control signals while also engaging in bidirectional data exchange with the remote controller and access point.

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

Solution Approach 2:

The access point serves as an intermediary device that facilitates communication between the remote controller and the background server. It receives 2.4G signals from the remote controller, extracts the embedded electronic shelf label identity and operation type, and forwards this information to the server for processing, enabling indirect but efficient data interaction.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If the electronic shelf label system uses traditional unidirectional control, then the system structure is simple, but real-time information feedback and management efficiency are limited

Engineering Contradiction:
Improvemanagement efficiencyVSAvoidsystem structure complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system implements a feedback mechanism where the remote controller can acquire information from the electronic shelf label (such as display content and identity) and transmit it to the access point and background server. The server can then process this information and send updated commands back to the electronic shelf label, creating a closed-loop feedback system that enables real-time monitoring and management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The remote controller is pre-configured with multiple operation types (price modification, inventory query, goods replenishment, inspection) that can be selectively activated. The magnetic control switch allows for preliminary selection of the desired operation before the actual control action is executed, enabling more efficient and targeted management operations.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the remote controller acquires information from the electronic shelf label using magnetic control switch and 2.4G protocol, then bidirectional interaction is achieved, but the complexity of the control mechanism increases

Engineering Contradiction:
Improveinteraction functionalityVSAvoidcontrol operation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The electronic shelf label automatically responds to the remote controller's inquiry signals by transmitting its identity and display information back to the remote controller. This self-service mechanism eliminates the need for complex manual configuration or setup, as the label provides the necessary information autonomously when triggered by the remote controller's magnetic control switch.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent combines the magnetic control switch triggering mechanism with the 2.4G wireless communication protocol in a unified control flow. The magnetic control switch activation simultaneously initiates the information acquisition process and selects the operation type, merging multiple control functions into a single integrated operation that simplifies the user interface.

Inventive Principle:
Principle #5Merging (Combining)
