Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data transmission modules and power transmission modules are combined in one plug connector, then space efficiency and ease of handling are improved, but electromagnetic interference increases and data transmission rate deteriorates
Solution Approach 1:
The plug connector is divided into separate modules: data transmission modules and power transmission modules. Each module is housed in its own housing with distinct contact pairs, allowing them to be combined in a single plug connector while maintaining electrical separation. This segmentation enables space efficiency through modular combination while preventing electromagnetic interference between data and power contacts.
2Ease of operation
If data contact pairs are arranged in a compact modular structure, then ease of operation and space saving are improved, but susceptibility to electromagnetic interference increases
Solution Approach 1:
Data contact pairs are segmented into separate groups within individual modules, each group isolated in its own housing section. This modular segmentation maintains ease of assembly through standardized interfaces while reducing electromagnetic interference by physically separating contact pairs that carry different signals.
Solution Approach 2:
Different regions of the plug connector housing are assigned different functional qualities: data transmission regions with shielded contact pairs and power transmission regions with separate contact pairs. This local differentiation allows compact modular design while applying appropriate electromagnetic shielding only where needed for data integrity.
3Productivity
If shielding elements are added to protect data contact pairs, then data transmission rate is improved, but device complexity increases
Solution Approach 1:
The shielding elements are merged with the housing structure itself rather than being separate components. The housing is designed with integrated shielding features that form continuous protective enclosures around data contact pairs, achieving high data transmission rates while avoiding the complexity of additional separate shielding parts.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides mechanical support for contact pairs, creates the modular interface for assembly, and incorporates electromagnetic shielding. This multi-functionality reduces device complexity by eliminating the need for separate shielding components while maintaining high data transmission rates through effective electromagnetic protection.
