Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If base station communication is used for M2M communication, then communication infrastructure is established, but latency time increases and transmission capacity is limited

Engineering Contradiction:
Improvecommunication reliabilityVSAvoidlatency time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent introduces a V2X communication system as an intermediary that enables direct peer-to-peer communication between vehicles and infrastructure without relying on base stations. This mediator architecture allows vehicles to exchange position and movement information directly, eliminating the latency introduced by base station relay while maintaining communication reliability through dedicated short-range communication protocols

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If object position estimation is performed using existing technologies, then position information is obtained, but measurement precision is insufficient for accurate direction recognition

Engineering Contradiction:
Improveposition estimation precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines multiple positioning technologies (GPS, IMU, UWB) into a unified position estimation system that achieves high measurement precision. By merging these complementary technologies, the system overcomes the limitations of individual methods and achieves accurate position and direction recognition without requiring overly complex standalone systems

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements real-time feedback mechanisms where position estimation results are continuously updated and verified through mutual information exchange between objects. This feedback loop enables the system to refine position estimates and improve measurement precision dynamically while maintaining manageable system complexity through iterative optimization

Inventive Principle:
Principle #23Feedback

3Reliability

If real-time position and movement path information is exchanged between objects, then accident risk is reduced, but communication transmission capacity requirements increase

Engineering Contradiction:
Improvesafety reliabilityVSAvoiddata transmission volume
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts and transmits only the essential elements needed for safety - position coordinates, movement direction, and speed information - rather than transmitting complete object state data. This selective extraction of critical information reduces the data transmission volume while maintaining sufficient information for real-time collision avoidance and safety monitoring

Inventive Principle:
Principle #2Taking out (Extraction)
