Solution Overview
Problem
Existing electrical connectors face challenges in achieving high-speed signal transmission with stability while maintaining a compact design and controlling costs, especially with the advent of 5G technology, which requires more complex connector designs and higher data capacity.
Innovation Solution
The electrical connector design incorporates an insulating housing with multiple transmission modules, each featuring a terminal assembly adhered to a flexible printed circuit board, including conductive pieces and pads, which are arranged to minimize signal interference and maximize space efficiency, using hot melt glue for secure mounting and a shell for shielding, thereby enhancing signal stability and maintaining force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed transmission technology is used to achieve faster signal transmission, then transmission speed is improved, but connector design complexity increases
Solution Approach 1:
The connector is divided into multiple independent transmission modules, each handling specific high-speed signal transmission tasks. This segmentation allows the complex high-speed transmission function to be distributed across multiple simpler, standardized modules, reducing overall design complexity while maintaining high transmission speed capability
Solution Approach 2:
The patent changes physical parameters such as using plated conductive pieces with specific geometries (finger-like shapes), optimizing the arrangement of pads and conductive elements, and adjusting material properties to achieve high-speed transmission characteristics without requiring overly complex structural designs
2Reliability
If connector design is made more complex to support 5G high-speed transmission, then signal transmission stability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the connector into standardized transmission modules with repeated structures (multiple pads, conductive pieces, and terminal assemblies), the patent achieves reliable high-speed transmission through proven modular designs while reducing manufacturing costs via economies of scale and simplified production processes
Solution Approach 2:
The patent employs homogeneous materials and uniform structural patterns across multiple transmission modules, using consistent plating processes, identical pad configurations, and standardized terminal assemblies. This homogeneity ensures stable signal transmission while simplifying manufacturing and reducing costs through process standardization
3Speed
If more components are added to achieve high-speed transmission, then transmission performance is improved, but internal space consumption increases
Solution Approach 1:
The patent implements a nested arrangement where terminal assemblies are positioned within the insulating housing, conductive pieces are embedded in the housing structure, and multiple transmission modules are stacked or arranged in compact configurations. This nesting approach allows high-speed transmission components to be integrated within limited space without excessive volume consumption
Solution Approach 2:
The patent utilizes three-dimensional space efficiently by arranging transmission modules, pads, and conductive pieces in multiple dimensions within the insulating housing, rather than simple linear arrangements. This spatial optimization enables high-speed transmission capability with compact overall dimensions
