Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed connectors in communication devices often experience poor contact due to the requirement for precise planeness and stamping height of ground pin terminals, leading to ineffective signal transmission.
Innovation Solution
A conductive sheet structure with elastic arms, including a connecting section, a tilt section, and a contact section, is designed to ensure effective contact with grounding terminals, allowing for variable tilt angles and elastic deformation to accommodate uneven terminal heights, thereby reducing the likelihood of poor contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If integral surface contact or single-point contact mode is used between conductive sheet and ground pin terminals, then the structure is simple, but the contact effectiveness deteriorates due to high requirements on planeness and stamping height
Solution Approach 1:
The conductive sheet is divided into multiple independent elastic arms instead of using an integral structure. Each elastic arm can independently contact with ground pin terminals, allowing local adaptation to height variations and improving contact reliability without significantly increasing overall structural complexity.
Solution Approach 2:
The elastic arms are designed to be deformable rather than rigid, enabling them to dynamically adapt to variations in ground pin terminal stamping height. This dynamic characteristic allows the contact sections to maintain effective contact even when terminal heights are inconsistent.
2Reliability
If precise planeness and stamping height control is implemented for ground pin terminals, then contact effectiveness improves, but manufacturing precision requirements increase
Solution Approach 1:
The invention changes the parameter of contact structure from rigid to elastic, allowing the contact sections to accommodate variations in terminal height through elastic deformation. This parameter change reduces the manufacturing precision requirements for ground pin terminals while maintaining effective contact.
Solution Approach 2:
The elastic arms function as flexible elements that can deform to match the actual height of ground pin terminals. This flexibility compensates for manufacturing tolerances in terminal stamping height, reducing the need for extremely precise manufacturing while ensuring reliable contact.
3Adaptability or versatility
If elastic arms with variable tilt angles are used, then adaptability to uneven terminals improves, but device complexity increases
Solution Approach 1:
The conductive sheet is segmented into multiple independent elastic arms, each capable of independent deformation. This segmentation provides adaptability to uneven terminals while keeping each individual arm's structure relatively simple, balancing adaptability and overall complexity.
