Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for coupling with printed circuit boards are difficult to assemble and disassemble, and they do not provide optimal signal transmission characteristics, particularly for high-frequency and high-power electrical signals.
Innovation Solution
A connector design featuring a printed circuit board with openings for mounting coaxial contacts, allowing for easy assembly and disassembly, and a contact device with contact pins and central/coaxial contacts that can be mounted independently, enabling application-specific signal transmission characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connector assembly methods are used, then the connector structure is stable, but the assembly process is difficult and time-consuming
Solution Approach 1:
The connector is divided into separate modular components: a connector body with contact pins, and separate coaxial contacts that can be independently mounted. This segmentation allows each component to be prepared separately and assembled through simple insertion through openings in the circuit board, dramatically simplifying the assembly process while maintaining structural stability.
Solution Approach 2:
The connector body and contact pins are pre-assembled into an integrated unit before mounting to the circuit board. The openings in the circuit board are pre-positioned to align with the contact device, enabling straightforward installation of the coaxial contacts without requiring complex alignment or adjustment during the assembly process.
2Reliability
If coaxial contacts are integrated into the connector body, then signal transmission is improved, but disassembly and reassembly become difficult
Solution Approach 1:
The coaxial contacts are designed as separate, detachable components from the connector body, allowing them to be independently removed and reinstalled. This segmentation maintains the reliable signal transmission path between the coaxial contact and connector body while enabling easy disassembly for repair, replacement, or reconfiguration without damaging other components.
3Productivity
If multiple contact pins are used, then signal transmission capacity is increased, but the risk of interference between signals increases
Solution Approach 1:
The connector body serves as an intermediary structure that provides physical separation and electromagnetic shielding between multiple contact pins and coaxial contacts. The connector body's geometry and material properties act as a barrier that prevents signal interference while maintaining high transmission capacity across all contacts.
