Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional specialized test equipment and trained technicians are used for network performance testing, then measurement precision and reliability are improved, but device complexity, cost, and time consumption increase significantly

Engineering Contradiction:
Improvenetwork performance measurement accuracyVSAvoidtesting system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses personal wireless devices (smartphones, tablets) as copies of traditional specialized test equipment. These consumer devices replicate the essential measurement functions through software applications that leverage the devices' existing sensors and communication capabilities, eliminating the need for expensive specialized hardware while maintaining measurement accuracy

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent makes personal wireless devices universal testing tools by enabling them to perform multiple network performance measurement functions through software. The same device can conduct various measurements (signal strength, throughput, latency) and report to different network elements, replacing the need for multiple specialized test devices

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

2Reliability

If traditional vehicles with specialized equipment are deployed for network testing, then measurement reliability is improved, but loss of time and productivity decrease

Engineering Contradiction:
Improvetesting result reliabilityVSAvoidtesting speed and efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent enables personal wireless devices to autonomously perform measurements and report results without requiring trained technicians or specialized equipment. The devices self-manage the testing process by automatically executing measurement protocols, collecting data, and transmitting results to network elements, thereby eliminating human intervention bottlenecks

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements preliminary configuration where network elements send triggering events and measurement instructions to personal devices before actual measurements are taken. This pre-configuration ensures that devices are ready to perform reliable measurements immediately when triggered, reducing overall testing time while maintaining result accuracy

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If traditional testing procedures are used, then measurement precision is maintained, but loss of time increases due to outdated results from inadequate test procedures

Engineering Contradiction:
Improvenetwork metric measurement accuracyVSAvoidtime for obtaining test results
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements real-time feedback mechanisms where personal wireless devices continuously monitor network conditions and immediately report measurement results upon triggering events. This continuous feedback loop ensures that network performance data is current and up-to-date, eliminating the delays associated with traditional batch testing procedures

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent employs periodic triggering events that stimulate personal devices to perform measurements at regular intervals or when specific conditions occur. This periodic action ensures consistent updates of network performance data without requiring continuous manual intervention, thereby reducing time loss while maintaining measurement precision

Inventive Principle:
Principle #19Periodic action
