Solution Overview

Problem

Coupled signals in electronic telecommunications systems experience significant insertion loss due to multiple switches and processing elements as they pass through interconnected modules, leading to signal attenuation.

Innovation Solution

Implementing a module architecture with bypass switches that allow signals to bypass processing elements, reducing the number of switches in the signal path and incorporating impedance networks to maintain consistent impedance characteristics across frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If signals pass through multiple switches and processing elements in interconnected modules, then signal processing functionality is achieved, but insertion loss increases significantly

Engineering Contradiction:
Improvesignal processing functionalityVSAvoidinsertion loss
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent extracts the harmful element (excessive switches and processing elements) from the signal path by introducing a bypass architecture. The bypass path allows signals to skip unnecessary processing elements and switches, directly connecting input to output when full processing is not required, thereby reducing insertion loss while maintaining processing capability when needed.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The bypass switch serves multiple functions: it can bypass individual processing elements, bypass entire modules, and work in combination with other bypass switches in cascaded systems. This multi-functionality allows a single component to address insertion loss at multiple levels of the signal path while maintaining full processing capability when required.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of energy

If bypass switches are added to reduce insertion loss, then signal attenuation decreases, but device complexity increases

Engineering Contradiction:
Improvesignal attenuationVSAvoiddevice complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The bypass architecture is segmented into modular components that can be implemented at different levels (intra-module and inter-module). Each bypass switch is a discrete, independently controllable element that can be added to existing modules without redesigning the entire system, making the complexity manageable and scalable.

Inventive Principle:
Principle #1Segmentation

3Loss of energy

If the number of switches in the signal path is reduced, then insertion loss decreases, but signal processing capability is compromised

Engineering Contradiction:
Improveinsertion lossVSAvoidsignal processing capability
Core Design Contradiction:
Loss of energyVSAdaptability or versatility

Solution Approach 1:

The bypass switches are dynamically controllable, allowing the system to adapt the signal path in real-time. When processing is needed, the bypass is disengaged and the full processing chain is active. When processing is not needed, the bypass is engaged to minimize insertion loss. This dynamic switching maintains both processing capability and low loss performance as needed.

Inventive Principle:
Principle #15Dynamics
