Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If MBD technology is applied to automobile part design, then data uniqueness and design efficiency are improved, but non-uniform application standards and lack of normalized standard systems create barriers in cross-industry cooperation
Solution Approach 1:
The patent develops a universal MBD application standard system that can be applied across different enterprises and industries. The standard includes unified data structures, model formats, and exchange protocols that enable multiple enterprises to use the same MBD framework, thus achieving both data uniqueness within each enterprise and cross-industry compatibility through standardized interfaces
2Ease of operation
If manual modeling functions of three-dimensional CAD software are used to create manufacturing feature bodies and procedure models, then flexibility in model creation is maintained, but repeated manual operations reduce creation efficiency and accuracy
Solution Approach 1:
The patent pre-establishes a standardized database of manufacturing feature bodies and procedure models with normalized data structures. During actual process design, these pre-defined templates can be selected and configured rather than created from scratch, significantly reducing manual operations while maintaining flexibility through parameter customization
Solution Approach 2:
The patent implements automated copying and reuse of manufacturing feature bodies and procedure models through the standardized database. Once a model is created or imported, it can be copied and adapted for similar features in different contexts, eliminating repeated manual modeling operations while maintaining accuracy through consistent data structures
3Ease of manufacture
If basic three-dimensional CAD software modeling functions are used without specialized MBD standards, then ease of implementation is maintained, but the requirements for normalization, accuracy and integrity of three-dimensional data cannot be met
Solution Approach 1:
The patent segments the MBD implementation into distinct layers: a standardized data structure framework that ensures normalization and integrity, and a user-friendly interface layer that maintains ease of operation. The segmentation allows the complex standardization requirements to be handled automatically by the system while users interact with simplified tools
4Productivity
If MBD technology is widely adopted in automobile enterprises, then process design efficiency is improved, but the lack of unified standard systems creates barriers in cross-enterprise and cross-industry cooperation
Solution Approach 1:
The patent develops a universal MBD application standard system that can be applied across different enterprises and industries. The standard includes unified data structures, model formats, and exchange protocols that enable multiple enterprises to use the same MBD framework, thus achieving both data uniqueness within each enterprise and cross-industry compatibility through standardized interfaces
Solution Approach 2:
The patent introduces a standardized data exchange format and interface protocol as an intermediary between different enterprise MBD systems. This intermediary layer enables seamless data exchange and collaboration between enterprises using the same standard, while allowing each enterprise to maintain its own internal MBD implementation details
