Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing relay connector apparatus faces high costs and deteriorating transmission characteristics due to the use of commercially-available connectors, which cause impedance mismatches during high-speed signal transmission.
Innovation Solution
A relay connector apparatus is designed with a housing, a printed circuit board, and a spring component for shell connection, where the spring component includes a cantilever beam or seesaw type spring piece that moves to establish contact between conductive shells, eliminating the need for separate connectors and reducing friction and wear debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If commercially-available connectors are used as connector parts, then the relay connector apparatus can be assembled using standard components, but the cost increases and impedance mismatches occur causing deterioration of transmission characteristics
Solution Approach 1:
The patent merges the connector part functionality directly into the housing structure. The housing now includes integrated contact points and conductive paths that eliminate the need for separate commercially-available connector parts, thereby reducing cost while maintaining transmission characteristics through customized impedance-controlled design
Solution Approach 2:
The housing is designed to serve multiple functions: it provides structural protection, establishes electrical connections through integrated contact points, and ensures proper impedance matching for high-speed signals. This multi-functional design replaces the need for separate connector components
2Ease of manufacture
If commercially-available connectors are used as connector parts, then the relay connector apparatus can be assembled using standard components, but impedance mismatches occur causing deterioration of transmission characteristics in high-speed signal transmission
Solution Approach 1:
The connector functionality is merged into the housing structure with integrated contact points and conductive paths. This customization allows for impedance-controlled design that matches high-speed signal requirements, eliminating the impedance mismatches caused by standard connectors while maintaining ease of assembly through the unified structure
3Reliability
If a spring component is designed to move during fitting operation to establish contact, then reliable electrical connection is achieved, but the structure becomes more complex
Solution Approach 1:
The patent employs a spring component with flexible contact points that deform during the fitting operation. This flexibility allows the contact points to establish reliable electrical connections with the conductive shells while accommodating manufacturing tolerances and assembly variations, achieving reliable connection without excessive structural complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution suppresses the increase in cost and deterioration of transmission characteristics by directly connecting the printed circuit board to the conductive shells, enhancing signal transmission while preventing interference with mounted components.
Implementation Method 1
a part between the one end and the other end may include a pivot point fixed to the body part, and during the fitting operation of the first connector, the first connector may push the force point, so that the first spring contact point moves in a direction toward the printed circuit board
Implementation Method 2
when the first connector is fitted to the one side of the housing, the first spring contact point is brought into contact with the first conductive shell, so that the first conductive shell and the second conductive shell become conductive
