Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robust but complex structure is used for electrical plugs and receptacles in motor vehicles, then reliability and protection against electromagnetic interference are improved, but manufacturing cost and complexity increase
Solution Approach 1:
The plug housing is divided into functionally independent partition walls that separate different cable areas. Each partition wall can be independently designed and manufactured, allowing for modular production while maintaining overall system reliability. The shield contact elements are also segmented and assigned to specific cable areas, enabling independent assembly and testing.
Solution Approach 2:
The plug housing is designed as a multi-functional component that simultaneously provides mechanical protection, electromagnetic shielding, and structural support for multiple cables. The partition walls serve both as physical separators and as mounting structures for shield contact elements, reducing the need for additional separate components and simplifying the overall device structure.
2Object-affected harmful factors
If shield contact elements and interlock devices are integrated into the plug housing, then protection against electromagnetic interference and arcing is improved, but manufacturing complexity increases
Solution Approach 1:
The shield contact elements and interlock devices are integrated directly into the plug housing structure itself, combining multiple protective functions into a single unified component. This eliminates the need for separate shielding components and interlock mechanisms, reducing the total number of parts while maintaining comprehensive protection against electromagnetic interference and arcing.
Solution Approach 2:
The plug housing structure itself provides the shielding and interlocking functions through its integrated design. The partition walls and shield contact elements work together automatically without requiring additional active components or complex control systems, allowing the housing to serve its own protective needs.
3Ease of manufacture
If simple and economic production is implemented, then manufacturing cost decreases, but protection against electromagnetic interference and environmental factors may be compromised
Solution Approach 1:
The plug housing provides electromagnetic shielding and environmental protection only in the specific local areas where cables are present and where partition walls are implemented. Rather than enclosing the entire plug in a complex shielded housing, protection is applied locally at each cable entry point and between adjacent cables, reducing material and manufacturing costs while maintaining necessary protection where required.

AI summary
The invention relates to a plug housing for an electrical plug for transmitting electrical drive power for a motor vehicle between a plug receptacle and a cable with an inner conductor, a shield and insulation between an inner conductor and the shield. The plug housing comprises a plug-in area, in which the plug may be connected to the plug receptacle, a cable area, in which the cable may be introduced into the plug housing, a partition wall between the plug-in area and the cable area and a first opening in the partition wall, which connects the cable area with the plug-in area, for accommodating an inner conductor element which is connected conductively with the inner conductor of the cable introduced into the cable area, such that the inner conductor element extends from the cable area as far as into the plug-in area. In addition, the plug housing comprises a second opening in the partition wall, which connects the cable area with the plug-in area, for accommodating a shield contact element which serves in contacting a further shield contact element of a plug receptacle connected with the plug and projects from the cable area into the plug-in area.
