RF Filter Cover Plate Tuning for Wider Range and Lower Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RF filters in wireless communication systems face challenges in achieving a wide tuning range while minimizing volume and weight, due to the use of traditional tuning methods that require additional space and manual adjustments, leading to increased production costs and defects.
Innovation Solution
A flexible tuning structure is integrated into the cover plate of the RF filter, allowing for automated adjustments without the need for screws or nuts, thereby reducing the filter's volume and weight by eliminating the need for additional components and manual tuning processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If traditional tuning methods with additional components (screws, nuts) are used, then tuning functionality is achieved, but volume and weight increase
Solution Approach 1:
The tuning structure is integrated directly into the cover plate, merging two separate components (cover plate and tuning mechanism) into a single unified structure. This eliminates the need for additional screws and nuts, thereby reducing volume and weight while maintaining tuning functionality.
Solution Approach 2:
The cover plate serves dual purposes: it acts as both the protective cover and the tuning structure. By making the cover plate itself adjustable and functional for tuning, the design eliminates separate tuning components, reducing overall device complexity and physical footprint.
2Productivity
If traditional manual tuning processes are used, then tuning accuracy is achieved, but productivity decreases
Solution Approach 1:
The tuning structure is designed to be self-adjusting or easily adjustable through the cover plate mechanism, eliminating the need for complex manual tuning procedures. This allows for faster setup and adjustment while maintaining tuning accuracy, thereby improving manufacturing productivity.
Solution Approach 2:
The patent replaces traditional mechanical tuning mechanisms (screws, nuts, manual adjustments) with an integrated cover plate-based tuning system that can be adjusted more efficiently. This substitution simplifies the tuning process and enables faster production cycles.
3Adaptability or versatility
If additional tuning components are added, then tuning range is extended, but manufacturing cost increases
Solution Approach 1:
By integrating the tuning structure into the cover plate itself, the patent extends tuning functionality without adding separate components. This merged design maintains adaptability and versatility while simplifying manufacturing processes and reducing production costs.
