Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for measuring wireless communication chipsets are time inefficient due to the need for unicast signals, which require acknowledgment waiting periods, leading to long test durations and high hardware requirements.

Innovation Solution

A measuring device that transmits an analog high frequency broadcast signal to devices under test, allowing direct reception and processing of measurement results without external control, using wireless or wired connections, thereby reducing hardware complexity and measurement time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If unicast signals are used for measurement, then reliable communication is ensured through acknowledgment, but measurement time increases significantly due to waiting periods

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidmeasurement time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent inverts the traditional unicast measurement approach by using broadcast signals instead. Instead of sending individual signals and waiting for acknowledgments, the system transmits broadcast signals that are received and measured simultaneously by multiple devices, eliminating the time-consuming acknowledgment waiting period while maintaining measurement reliability

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The patent enables continuous measurement by using broadcast signals that can be received without interruption. Unlike unicast signals that require sequential transmission and acknowledgment, broadcast signals allow continuous data transmission and simultaneous measurement by multiple devices, maintaining useful action throughout the measurement process

Inventive Principle:

Principle #20Continuity of useful action

2Adaptability or versatility

If additional measuring PC is added to receive measurement results, then measurement capability is enhanced, but hardware complexity and measurement time increase

Engineering Contradiction:

Improvemeasurement capabilityVSAvoidhardware complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements self-service by enabling the device under test to autonomously determine and transmit its own measurement results back to the measuring device. This eliminates the need for an external measuring PC to receive results, reducing hardware complexity while maintaining full measurement capability

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent merges the functions of the measuring device and the device under test by enabling direct communication between them. The measuring device transmits signals and receives measurements directly from the device under test, combining what would traditionally require separate devices into a single integrated measurement system

Inventive Principle:

Principle #5Merging (Combining)
