Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If power supply to loads is maintained for extended periods using fixed phased cut-off, then driver convenience is improved, but unnecessary current drainage increases

Engineering Contradiction:
Improvedriver convenienceVSAvoidcurrent drainage
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The patent applies dynamics by transitioning from fixed phased cut-off to dynamic adaptive cut-off. The system continuously monitors vehicle usage patterns through the network monitor and adjusts power cut-off timing based on learned patterns. This allows the power supply strategy to adapt dynamically to actual driver behavior, cutting power earlier when usage is unlikely and maintaining power longer when needed, thereby reducing unnecessary current drainage while preserving driver convenience.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback through the network monitor that continuously observes vehicle network states and driver interactions. This feedback loop provides real-time information about actual vehicle usage, which is then processed by the usage pattern learner to adjust future power cut-off decisions. The feedback mechanism enables the system to learn from past behavior and optimize power management, reducing energy loss while maintaining convenience.

Inventive Principle:
Principle #23Feedback

Solution Approach 3:

The system applies self-service by automatically learning and adapting to driver usage patterns without requiring manual input or configuration. The usage pattern learner autonomously analyzes network monitor data, identifies usage patterns, and adjusts power cut-off strategies independently. This self-learning capability allows the system to optimize battery performance and reduce current drainage automatically, improving both energy efficiency and user experience.

Inventive Principle:
Principle #25Self-service

2Reliability

If power supply is cut off early to reduce current drainage, then battery performance is improved, but driver convenience deteriorates

Engineering Contradiction:
Improvebattery performanceVSAvoiddriver convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system uses dynamics to adjust power cut-off timing based on learned usage patterns. Instead of fixed early cut-off, the system dynamically determines optimal cut-off points that balance battery protection with driver needs. By adapting cut-off timing to actual usage patterns, the system can cut power early when appropriate (improving battery performance) while maintaining power longer when driver interaction is expected (preserving convenience).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying power cut-off timing parameters based on learned usage patterns. The system adjusts temporal parameters (when to cut power) and conditional parameters (which loads to cut) based on analyzed driver behavior. This parameter adaptation allows optimization of battery performance through earlier cut-off in low-usage scenarios while maintaining convenience in high-usage scenarios.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If fixed phased power cut-off is used, then system complexity is minimized, but energy efficiency deteriorates

Engineering Contradiction:
Improvesystem complexityVSAvoidcurrent drainage
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The system applies self-service through automated usage pattern learning and adaptive control. Rather than requiring complex manual configuration or intervention, the system automatically monitors network states, learns usage patterns, and adjusts power management strategies independently. This self-learning capability achieves improved energy efficiency without proportionally increasing system complexity, as the learning algorithms operate autonomously using existing sensor data.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies universality by using the existing vehicle network monitor and controller for dual purposes: original communication functions and usage pattern learning for power management. The same hardware infrastructure supports multiple functions, avoiding the need for separate dedicated sensors or complex additional systems. This multi-functionality approach improves energy efficiency while minimizing the increase in overall system complexity.

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