Solution Overview

Problem

Existing near-field wireless communication protocols face processing delays due to higher priority orders for voice data over wireless serial communication commands, leading to bottlenecks in transmission-reception switching control and data processing between wireless devices and headsets.

Innovation Solution

The implementation of a near-field wireless communication module that processes data associated with wireless serial communication using a digital signal processor (DSP) instead of a microcontroller unit (MCU), along with a discriminator to differentiate between wireless serial communication data and other data, ensuring faster processing independent of existing priority orders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If voice data processing is prioritized over wireless serial communication commands in the existing near-field wireless communication protocol, then voice data communication efficiency is improved, but command processing speed deteriorates

Engineering Contradiction:

Improvevoice data processing efficiencyVSAvoidcommand processing delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent segments the data processing function by introducing a dedicated command processing unit that operates independently from the voice data processing path. This unit specifically handles wireless serial communication commands (such as PTT commands) separately, allowing command processing to proceed in parallel without being blocked by voice data processing priorities.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary command processing unit that acts as a mediator between the wireless communication module and the application layer. This intermediary unit captures and processes commands before they enter the main voice data processing queue, effectively bypassing the priority-based scheduling that causes delays.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If data processing is performed by the MCU in the existing near-field wireless communication module, then system control is simplified, but processing speed deteriorates

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSSpeed

Solution Approach 1:

The patent divides the processing architecture into two distinct paths: one handled by the MCU for control functions and another by the dedicated command processing unit for high-speed data processing. This segmentation allows the system to leverage the strengths of both components without the bottlenecks of a single-processing-architecture.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the traditional MCU-based processing mechanism with a specialized command processing unit that is optimized for high-speed wireless serial communication. This substitution transitions from a general-purpose control processor to a dedicated processing engine, significantly improving processing speed.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
