Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If expensive and complicated on-board systems are used for autonomous vehicles, then sensing and control functionalities are improved, but system cost and complexity increase significantly

Engineering Contradiction:
Improvesensing and control functionalitiesVSAvoidon-board system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts complex sensing, prediction, control, and security functionalities from the vehicle on-board systems and relocates them to a centralized cloud-based system. The vehicle retains only essential communication and execution components, while the cloud handles intensive processing tasks including environmental sensing data analysis, trajectory prediction, control command generation, and security monitoring.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces a communication interface as an intermediary between the vehicle and the cloud-based system. This intermediary enables the vehicle to receive high-level control commands and send sensing data without requiring complex on-board processing, effectively decoupling the vehicle's hardware complexity from the system's functional capabilities.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If comprehensive sensing and control systems are implemented in vehicles, then safety and connectivity are improved, but implementation cost increases

Engineering Contradiction:

Solution Approach 1:

The patent merges multiple vehicle functions (sensing, prediction, control, security) into a single cloud-based platform that serves multiple vehicles simultaneously. This consolidation allows shared infrastructure and resources to provide comprehensive safety and connectivity features at a lower per-vehicle cost compared to implementing identical systems in each vehicle.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If cloud-based services are implemented for CAVH systems, then system cost is reduced and accessibility is improved, but data security and privacy protection challenges arise

Engineering Contradiction:

Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The patent introduces multiple intermediary layers including authentication services, encryption mechanisms, and secure communication protocols between the cloud system and vehicles. These intermediaries protect sensitive data during transmission and storage while maintaining the cost-effectiveness of cloud-based deployment.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Productivity

If centralized cloud control is used for multiple vehicles, then coordination and efficiency are improved, but system vulnerability to cyber attacks increases

Engineering Contradiction:

Solution Approach 1:

The patent implements prior cushioning through preventive security measures including authentication services that verify vehicle identities before granting access, encryption protocols that protect data in transit, and intrusion detection systems that monitor for suspicious activities. These pre-established protective layers cushion the centralized control system against potential cyber attacks while maintaining coordination efficiency.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)
