Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, the existing radio frequency signal connection methods using screw-based PCB and cantilever beam structures face challenges with assembly tolerance, leading to deteriorated ground electrical properties and inability to meet high-frequency signal transmission requirements above 2.6 GHz due to lengthened signal return current paths.
Innovation Solution
A signal connection apparatus featuring a substrate with grooves and a conductive elastic piece that shortens the signal return current path by using a conductive adhesive to secure the elastic piece within the grooves, allowing the screw to contact the circuit board directly, thereby improving signal transmission quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connector and a plug are connected to each other, then electrical connection is established, but connection disconnection occurs due to repeated plugging and unplugging
Solution Approach 1:
A resin layer is formed in advance to cover the contact between the connector and plug, preventing direct mechanical contact and wear. This protective layer is applied before the damage occurs, cushioning against the harmful effects of repeated connection/disconnection cycles and maintaining electrical reliability throughout the connector's service life.
2Reliability
If resin is used to cover connector-plug contact, then connection reliability improves, but resin peeling occurs over time
Solution Approach 1:
A composite structure is created by forming a resin layer that integrates with the connector-plug interface. The resin is cured in place to create a bonded composite material system where the resin and metal components work together, improving adhesion stability and preventing peeling while maintaining connection reliability.
3Reliability
If resin is applied to connector-plug contact, then connection stability improves, but production complexity increases
Solution Approach 1:
The resin is applied in a self-contained manner where the resin layer is formed directly at the connector-plug interface through curing. The system performs its own manufacturing function by transforming the resin from liquid to solid state in situ, eliminating the need for complex external application equipment or multi-step assembly processes, thus maintaining manufacturing simplicity while achieving connection stability.
