Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If accelerometers inside computer hard disk drives are used for post-event analysis of seismic events, then cost-effectiveness in large-scale applications is improved, but the ability to provide improved post-event analysis of local damages deteriorates

Engineering Contradiction:
Improvecost-effectivenessVSAvoidpost-event analysis of local damages
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent applies multi-functionality by using the same vibration detector (accelerometer) for both preliminary wave detection and destructive wave analysis. The system processes different types of seismic events (tsunamis, earthquakes, landslides) and provides both early warning and post-event damage analysis using a unified detector design, enabling cost-effective large-scale deployment without sacrificing local damage assessment capability

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

Solution Approach 2:

The patent implements preliminary action by detecting preliminary seismic waves before destructive waves arrive. The system analyzes characteristics of preliminary waves to predict upcoming destructive events and prepares damage assessment frameworks in advance, enabling both early warning and pre-configured post-event analysis capabilities

Inventive Principle:
Principle #10Preliminary action

2Reliability

If a telecom network is provided with data processing means to receive warning signals from geographically dispersed vibration detectors, then the coverage and reliability of natural disaster alarms is improved, but the complexity of the system increases

Engineering Contradiction:
Improvenatural disaster alarmsVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a multi-purpose monitoring system that handles multiple disaster types (tsunamis, earthquakes, landslides) and multiple operational modes (early warning, post-event analysis) through a single integrated telecom network infrastructure. The data processing means processes various detector inputs uniformly, reducing overall system complexity despite enhanced functionality

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

Solution Approach 2:

The patent implements segmentation by dividing the monitoring system into geographically dispersed independent vibration detectors that each operate autonomously. Each detector processes local seismic data independently and transmits results to the central telecom network, allowing the system to scale reliably without proportionally increasing central processing complexity

Inventive Principle:
Principle #1Segmentation

3Measurement precision

If vibration detectors send status reports on local capacitances within a preset time window, then the quality of post-event analysis is improved, but the loss of time for alarm message transmission increases

Engineering Contradiction:
Improvepost-event analysis of local damagesVSAvoidalarm message transmission
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having detectors continuously monitor and pre-process local capacitance data during the preset time window before destructive waves arrive. This preliminary data collection and processing enables rapid post-event analysis without delaying alarm message transmission, as the analysis framework is already prepared in advance

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by adjusting the operational mode of detectors based on seismic event phase. During preliminary wave detection, detectors focus on early warning signals. When destructive waves are detected, the system dynamically switches to prioritize detailed local capacitance monitoring and post-event analysis, optimizing both time sensitivity and measurement precision at different stages

Inventive Principle:
Principle #15Dynamics
