Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed filter is used for frequency assignment in wireless communication systems, then the system structure is simple and stable, but the frequency bandwidth cannot be freely adjusted and unsupported frequencies cannot be utilized
Solution Approach 1:
The patent implements dynamic filter coefficient adjustment by allowing the filter characteristics to be changed remotely through a management terminal. The filter coefficient database stores multiple sets of coefficients that can be selected and applied based on different frequency bandwidth requirements, transforming a static filter system into a dynamic one that can adapt to various communication scenarios without physical hardware changes.
Solution Approach 2:
The patent introduces a management terminal as an intermediary between the user and the wireless communication system. This intermediary provides a web-based interface that enables remote configuration of filter coefficients, allowing users to adjust frequency bandwidth settings without directly accessing or modifying the physical filter hardware, thus simplifying the user interface while maintaining system flexibility.
2Adaptability or versatility
If additional products are developed to support public and special frequencies, then frequency coverage is improved, but development cost, production cost, and maintenance cost increase
Solution Approach 1:
The patent makes a single wireless communication system universally applicable to multiple frequency bands by implementing a filter coefficient database that stores coefficients for different frequency assignments. Instead of developing separate hardware products for each frequency band, the system can load appropriate filter coefficients to support various frequency ranges, including public and special frequencies, thereby achieving multi-functionality with a single product platform.
Solution Approach 2:
The patent changes the filter characteristics by modifying the filter coefficient parameters rather than changing the physical filter hardware. By storing multiple sets of filter coefficients in a database and loading the appropriate set based on the desired frequency band, the system can adapt to different frequency requirements through parameter changes alone, eliminating the need for additional hardware development for each frequency band.
3Ease of operation
If filter coefficients are previously stored and selected from fixed options, then the system operation is simple, but detailed and free setting of desired frequency bandwidth is not possible
Solution Approach 1:
The patent introduces a management terminal with a web-based interface as an intermediary that provides both simple and detailed configuration options. For basic operations, users can select from predefined filter settings, maintaining ease of operation. For advanced needs, users can access detailed filter coefficient parameters and make custom adjustments, thereby achieving both simplicity and flexibility through the intermediary interface.
Solution Approach 2:
The patent implements a dynamic configuration system where filter coefficients can be adjusted in real-time based on user requirements. The system transitions from static pre-configured filters to dynamic adjustable filters, allowing users to freely set desired frequency bandwidths by loading different coefficient sets from the database or making custom modifications through the management terminal.

AI summary
A method for setting a filter coefficient for a communication system, which adjusts a frequency bandwidth by setting a filter coefficient of a wireless communication system over a communication network, is provided. In the method, a wireless communication system that includes a controller having a filter coefficient database and a web server, and a Digital Signal Processing device requests a filter coefficient and attribute information related to a set target frequency bandwidth from a management terminal. The wireless communication system receives the filter coefficient and the attribute information from the management terminal and stores the filter coefficient and the attribute information in the filter coefficient database. The wireless communication system sets a frequency bandwidth of the digital signal processing device as a set target frequency bandwidth based on the stored filter coefficient and the attribute information.
