Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If address codes are written into LED display devices one by one by a coder, then each device can be properly addressed, but the writing operation is time-consuming and inefficient

Engineering Contradiction:

Improveaddress code writing efficiencyVSAvoidtime for writing operation

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent merges multiple address code writing operations into a single parallel operation. By connecting LED display devices in parallel and using a parallel architecture pattern, the system can write address codes to multiple devices simultaneously through shared signal buses, transforming sequential writing into concurrent writing operations.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system performs preliminary configuration by setting up parallel connections and establishing address code assignment rules before the actual writing operation. The controller is pre-configured with the ability to generate and distribute address codes to multiple devices in a predetermined sequence, enabling efficient batch writing without manual intervention for each device.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If a parallel architecture pattern is used where all LED display devices share the same signal bus, then the system can support multiple devices, but address code writing becomes complex and inefficient

Engineering Contradiction:

Improvenumber of devices supportedVSAvoidaddress code writing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements feedback mechanisms where LED display devices send acknowledgment signals back to the controller after successfully receiving address codes. The controller monitors these feedback signals to determine when all devices have been properly addressed, automatically managing the writing process without requiring complex manual tracking or configuration.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Each LED display device autonomously receives and stores address codes from the shared signal bus based on timing and addressing protocols. The devices self-configure their address identifiers without requiring individual manual programming, allowing the system to scale to multiple devices while maintaining simple writing operations.

Inventive Principle:

Principle #25Self-service

3Reliability

If manual coding is performed during production or installation, then each LED display device can be properly configured, but the process affects production efficiency and tooling test efficiency

Engineering Contradiction:

Improvedevice configuration accuracyVSAvoidproduction efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical coding operations with an automated electronic system. The controller electronically generates and transmits address codes to LED display devices through electrical signal buses, eliminating the need for manual configuration procedures and significantly improving production efficiency while maintaining configuration accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

LED display devices automatically receive and configure their address codes from the controller without requiring manual intervention. The automated writing process ensures consistent and accurate configuration across all devices, improving both reliability and production efficiency by eliminating human error and manual labor.

AI summary

The present invention relates to data coding control field, and provides a method and system for writing address codes into LED display devices. According to the embodiments of the present invention, when all the LED display devices in parallel in the display module are in series with the same number of LED display devices, the address code is written into the primary LED display device and LED display devices in series with the primary LED display device respectively according to the preset address code and the preset number in the series connection, and the address code is written into one or more LED display devices connected in parallel with the primary LED display device and LED display devices connected in series with each of the one or more LED display devices in parallel with the primary LED display device successively in an address code ascending manner. Thus address codes are written into the LED display devices at a time, it is not necessary to write address codes into the LED display devices one by one, therefore, the efficiency of writing codes is improved.
