Ferromagnetic Powder Adapter for Stable Passive Intermodulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing passive intermodulation sources in mobile radio networks are not shockproof and temperature-stable, leading to variability in intermodulation values across input power and frequency, causing interference in high-sensitivity receivers.
Innovation Solution
A shockproof and temperature-stable adapter module using ferromagnetic powder, fixed in a materially bonded manner within a housing niche, influences the magnetic field for consistent intermodulation performance, ensuring the powder remains in place and does not contact conductive contacts, thus enhancing shock resistance and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ferromagnetic components are used as the source of intermodulation, then passive intermodulation can be generated, but the components are not shockproof and not temperature-stable
Solution Approach 1:
The patent changes the physical state of ferromagnetic material from solid components to ferromagnetic powder, and fixes it in a materially bonded manner within the housing niche. This parameter change enables the system to be shockproof and temperature-stable while maintaining consistent intermodulation values across varying input power and frequency conditions.
2Reliability
If ferromagnetic powder is used to influence the magnetic field, then intermodulation performance becomes consistent, but the powder may move under shock or temperature changes
Solution Approach 1:
The ferromagnetic powder is preliminarily fixed in a materially bonded manner within the housing niche before the adapter module is put into service. This preliminary fixation ensures that the powder remains in place under shock or temperature changes, maintaining both position stability and consistent intermodulation performance.
3Object-generated harmful factors
If the first conductive contact is surrounded by ferromagnetic material, then magnetic field influence is maximized, but electrical contact may be compromised
Solution Approach 1:
The patent introduces an insulating layer as an intermediary between the first conductive contact and the ferromagnetic powder. This insulating layer allows the conductive contact to maintain reliable electrical connection while still enabling the ferromagnetic powder to influence the magnetic field for intermodulation generation.
