1Object-affected harmful factors

If metallic connector housings are used for shielding, then shielding effectiveness is improved, but manufacturing complexity and cost increase significantly

Engineering Contradiction:
Improveshielding effectivenessVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The shielding function is segmented from the connector housing and implemented separately through shield transfer elements that can be added to modular connector modules. This allows the housing to remain simple while providing shielding where needed through separate components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The shielding functionality is extracted from the metallic housing and implemented through separate shield transfer elements made of conductive material. This extraction allows the housing to be made of simpler, less expensive materials while maintaining shielding effectiveness through the dedicated shield components.

Inventive Principle:
Principle #2Taking out (Extraction)

2Speed

If high-frequency signal transmission is required, then data transmission capability is improved, but susceptibility to interference from adjacent high-current modules increases

Engineering Contradiction:
Improvedata transmission speedVSAvoidinterference from high-current modules
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

Shielding is applied locally to specific connector modules that require high-frequency signal transmission. The shield transfer elements are selectively positioned on modules needing protection, providing localized electromagnetic shielding without requiring all modules to be shielded, thus addressing interference issues where they occur.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If modular connector system with mixed modules (high current and high-frequency) is created, then versatility is improved, but mutual interference between modules increases

Engineering Contradiction:
Improveconnector configuration flexibilityVSAvoidmutual interference between modules
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The shield transfer elements act as intermediary components between adjacent connector modules. When positioned between a high-current module and a high-frequency module, they serve as a barrier that prevents electromagnetic interference while allowing both module types to coexist in the same modular system.

Inventive Principle:
Principle #24Intermediary (Mediator)
