Design Management Device Data Transmission Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing production management systems face issues with data overflow due to unnecessary information transmission when design changes occur, as they do not efficiently manage configuration information for parts, leading to increased data load and complexity.
Innovation Solution
A design management device and method that store unit design data and product design data, with a transmission control unit that omits part design data if unit design data has been previously transmitted, ensuring only necessary data is sent to the production management system, thereby simplifying data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all part design data is transmitted to the production management device when design changes occur, then complete design information is provided, but data overflow and information complexity increase
Solution Approach 1:
The patent extracts and transmits only the changed portion (unit design data) rather than all part design data. The transmission control unit determines whether unit design data has been transmitted before, and only transmits part design data corresponding to changes, thereby reducing data volume while maintaining information completeness.
Solution Approach 2:
The patent segments design data into product design data and unit design data (assembly-level data), and further into part design data. This hierarchical segmentation allows selective transmission of only necessary segments (changed unit design data and corresponding part design data) rather than transmitting the entire dataset.
2Reliability
If duplicate part design data is transmitted when design changes occur, then all design information is ensured, but data management complexity and processing load increase
Solution Approach 1:
The transmission control unit uses feedback from the determination unit (which checks whether unit design data has been transmitted before) to control the transmission of part design data. This feedback mechanism prevents duplicate transmissions and reduces data management complexity while ensuring data accuracy.
Solution Approach 2:
The system dynamically adjusts the transmission of part design data based on the determination result. When unit design data is newly transmitted, corresponding part design data is transmitted; when unit design data has been transmitted before, part design data is omitted. This dynamic approach reduces complexity while maintaining reliability.

AI summary
A design management device for managing data has a unit design storage section for storing unit design data with corresponding part design data, a product design storage unit for storing product design data together with the corresponding unit design data, a data transmission unit for sending the product design data to the production management device together with the unit design data and the part design data, a transmission determination unit for determining whether or not the unit design data was transmitted in the past, and a transmission control unit that does not transmit corresponding part design data when the unit design data determined to have been transmitted in the past is sent.
