Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-pole plug-in connectors face challenges in achieving high mechanical stability while maintaining good high-frequency characteristics, particularly in reducing crosstalk and throughput attenuation, and require additional screening elements which increase material consumption and complexity.
Innovation Solution
The multi-pole plug-in connector features contact elements with a flat plug-in area that transitions to a flat conduction area, where the wide side of the plug-in area is rotated by a predefined angle relative to the conduction area, reducing material consumption and allowing for a higher number of contacts per surface area, while also optimizing spacing and surge impedance without additional screening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional flat screening elements are provided for signal-carrying contact elements, then high-frequency characteristics are improved, but device complexity and material consumption increase
Solution Approach 1:
The patent merges the screening function with the contact element structure itself. The contact elements are arranged in a configuration where they serve both as signal carriers and as screening elements for adjacent contacts, eliminating the need for separate flat screening elements. This integration maintains high-frequency characteristics while reducing device complexity and material consumption.
Solution Approach 2:
The contact elements are designed to perform multiple functions: they serve as signal-carrying conductors and simultaneously act as screening elements for adjacent signal paths. This multi-functionality approach eliminates the need for dedicated screening components, thereby reducing overall device complexity while maintaining electromagnetic shielding effectiveness.
2Object-generated harmful factors
If contact elements are arranged with larger spacing, then crosstalk is reduced, but area occupied increases
Solution Approach 1:
The patent combines the spacing strategy with the multi-row arrangement to achieve crosstalk reduction without excessive area increase. By strategically spacing contacts within the compact multi-row geometry, the design minimizes electromagnetic coupling between adjacent signal paths while maintaining high contact density.
Solution Approach 2:
The patent transitions from a single-plane contact arrangement to a multi-row three-dimensional configuration. This dimensional change allows for optimized spacing patterns that reduce crosstalk between adjacent contacts while maintaining compact overall dimensions through vertical stacking of contact rows.
3Productivity
If more contact elements are packed into available surface area, then productivity is improved, but mechanical stability deteriorates
Solution Approach 1:
The patent achieves high contact density by utilizing a multi-row three-dimensional arrangement instead of packing all contacts into a single plane. This vertical stacking approach increases the number of contacts per surface area while maintaining adequate spacing and structural support for each contact element, thereby preserving mechanical stability.
Solution Approach 2:
The contact array is segmented into multiple rows with optimized spacing and arrangement. This segmentation allows each contact element to maintain its mechanical integrity while achieving high overall density through the distributed multi-row configuration rather than dense single-plane packing.
4Area of stationary object
If spacing between contact elements is reduced, then area is saved, but throughput attenuation increases
Solution Approach 1:
The patent uses multi-row vertical stacking to reduce the horizontal footprint while maintaining adequate spacing between signal paths. This three-dimensional arrangement saves surface area while preserving the electromagnetic field distribution needed to minimize throughput attenuation.
Solution Approach 2:
The contact spacing is optimized locally for each row and column position within the multi-row structure. This localized optimization allows different spacing configurations in different regions, saving area where possible while maintaining adequate spacing to control throughput attenuation for high-frequency signals.
