Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems and relaying devices are limited in enabling mutual communications between wireless apparatuses with different communication schemes, such as analog and digital, or full-duplex and half-duplex, preventing effective communication across disparate communication areas.
Innovation Solution
A relaying device with multiple communication paths, including wireless apparatus interfaces, signal processing units, and packet processing units, that allow for additive synthesis and ORing of audio signals and detection signals across different communication paths, enabling communication between wireless apparatuses of various schemes by converting audio signals into packets and vice versa, and allowing user selection of mixing functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a relaying device is configured to enable communications of transceivers in different communication areas, then communication coverage is improved, but the device can only support transceivers of the same communication scheme (analog half-duplex)
Solution Approach 1:
The relaying device is divided into multiple independent communication paths, where each path is dedicated to a specific communication scheme (analog half-duplex, full-duplex, digital). This segmentation allows the device to support multiple communication schemes simultaneously while maintaining clear functional boundaries and manageable complexity within each path.
Solution Approach 2:
The relaying device is designed with multi-functional capability by incorporating multiple communication paths that can handle different communication schemes. Each path can be independently configured to support specific schemes, making the overall device universal and adaptable to various communication requirements without requiring separate dedicated devices for each scheme.
2Adaptability or versatility
If transceivers of different communication schemes (full-duplex and half-duplex, analog and digital) are present in the same communication area, then communication diversity is improved, but direct communications between them are not possible
Solution Approach 1:
The relaying device acts as an intermediary between transceivers of different communication schemes. It receives signals from transceivers using one scheme through dedicated communication paths, processes and converts them, then transmits to transceivers using different schemes. This intermediary function enables reliable communication between disparate schemes that would otherwise be incompatible for direct communication.
Solution Approach 2:
The device enables communication between different schemes by changing key communication parameters including modulation type, duplex mode, and signal format. Each communication path is configured with appropriate parameter settings for its designated scheme, allowing the device to transform signals between different parameter sets and facilitate reliable communication across scheme boundaries.
