Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If certified safety components with fixed functions and standardized interfaces are used, then system simplicity and modularity are improved, but adaptability to changing process conditions and fault scenarios deteriorates

Engineering Contradiction:
Improvesystem simplicityVSAvoidadaptability to changing conditions
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent implements a dynamic safety system where the safety controller can dynamically adjust safety functions based on real-time sensor data quality assessment. The system transitions from static, fixed safety functions to dynamic, adaptive safety functions that can be modified during operation based on detected inconsistencies or poor quality sensor data, thereby resolving the contradiction between simplicity and adaptability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of safety function configuration from fixed to variable. By introducing a quality assessment mechanism that evaluates sensor data in real-time and dynamically adjusts safety function parameters based on data quality, the system achieves both simplicity through standardized interfaces and adaptability through parameter modification capability.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If strict encapsulation and certified safety components with defined functions are employed, then system reliability is improved, but flexibility and resilience to faults deteriorates

Engineering Contradiction:
Improvesafety function reliabilityVSAvoidflexibility to fault scenarios
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a feedback mechanism where the safety controller continuously assesses the quality of sensor data and uses this feedback to dynamically adjust safety functions. This feedback loop enables the system to maintain reliability through certified components while gaining flexibility to adapt to fault scenarios and data quality variations, resolving the contradiction between reliability and flexibility.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system implements beforehand cushioning by proactively assessing sensor data quality and dynamically adjusting safety functions before faults manifest. When poor quality or inconsistent sensor data is detected, the system preemptively modifies safety functions to compensate, preventing potential safety issues while maintaining system flexibility.

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

3Reliability

If the safety function is rigid and completely stops the vehicle upon detecting inconsistencies, then safety is improved, but productivity deteriorates

Engineering Contradiction:
Improvehazard preventionVSAvoidoperational continuity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent transforms the rigid, binary safety response (stop or continue) into a dynamic, graduated response system. The safety controller dynamically adjusts the vehicle's operation based on the severity and type of detected inconsistencies, allowing continued operation with modified safety functions when appropriate, thereby resolving the contradiction between hazard prevention and operational continuity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the parameter of safety response from fixed (complete stop) to variable (graduated responses). By introducing multiple operational states and dynamically adjusting safety function parameters based on sensor data quality assessment, the system achieves both improved hazard prevention and maintained productivity through context-appropriate responses.

Inventive Principle:
Principle #35Parameter changes

4Device complexity

If localized safety safeguards at the point of danger are used, then device complexity is reduced, but measurement precision and information content deteriorates

Engineering Contradiction:
Improvesafety system complexityVSAvoidsensor data information content
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent implements a universal safety controller that performs multiple functions: it manages localized safety safeguards while also consolidating and assessing sensor data from multiple sources across the entire system. This multi-functional approach allows the system to maintain low complexity at the component level while achieving high measurement precision through centralized data consolidation, resolving the contradiction between complexity and information content.

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