Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If base stations are constantly upgraded to support new modulation schemes and frequency spectrums, then adaptability is improved, but device complexity and capital expenditure increase

Engineering Contradiction:

Improvesupport for new modulation schemes and frequency spectrumsVSAvoidhardware upgrades

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces hardware-based frequency and modulation support with software-based solutions. The base station uses software-defined radio (SDR) architecture where modulation schemes and frequency spectrums are changed through software updates rather than physical hardware upgrades. This substitution of mechanical/hardware systems with software systems enables flexible adaptation to new communication standards without increasing device complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements dynamic parameter changes in the base station configuration. By allowing software-based reconfiguration of frequency spectrums and modulation schemes, the system can adapt to new standards by changing operational parameters rather than replacing hardware components. This enables the base station to support multiple frequency bands and modulation types through software updates alone.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If hardware upgrades are performed to support new technologies, then adaptability is improved, but loss of time and capital expenditure increase

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent employs preliminary action by pre-configuring the base station with software frameworks that enable rapid deployment of new modulation schemes and frequency spectrums. The software-defined architecture is prepared in advance with modular components that can be quickly instantiated through software updates, eliminating the need for time-consuming hardware replacement processes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By substituting hardware upgrade processes with software-based configuration, the patent eliminates the physical time required for hardware installation, removal, and reconfiguration. Software updates can be deployed remotely and instantaneously, dramatically reducing the time loss associated with technology upgrades.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements universality through a single software-defined radio platform that can perform multiple functions. The base station uses universal software frameworks that enable it to handle various frequency spectrums and modulation schemes through a common processing architecture, eliminating the need for separate dedicated hardware components for each function.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces multiple specialized hardware components with a unified software-based processing system. Instead of having separate hardware modules for different frequency bands and modulation types, the system uses a single software-defined radio platform that processes all signals through common digital signal processing algorithms, thereby reducing device complexity while maintaining multi-functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The Distributed Combined Junctional Transformer (abbreviated in this document as repeater station) provides a system to take any input wireless signal in any frequency and using any modulation and multiplexing schemes, convert it to the desired format and frequency and subsequently transmits the new wireless signal. In accordance with an embodiment of the invention, a repeater station comprises: an input antenna section capable of receiving the input signal generated by any source device in radio, microwave, infrared, visible or ultraviolet spectrums; an input conversion section translating the input wireless signal to a baseband signal if required; a baseband processing section that interprets the information of the input signal, converts the signal to the desired format and controls the other sections; an output conversion section which translates the baseband frequency output signal to the desired carrier output frequency if required; and an output antenna section which transmits the output signal.
