Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a multiplex system is employed to maintain control when hardware malfunction occurs, then system reliability is improved, but the ability to provide appropriate control tailored to specific malfunction situations deteriorates

Engineering Contradiction:

Improvesystem reliabilityVSAvoidadaptability to specific malfunction situations

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The control device dynamically adjusts control contents based on the type and severity of malfunction detected. The system transitions from static multiplex redundancy to dynamic adaptive control, where control strategies change in real-time according to the specific malfunction situation and peripheral conditions, resolving the contradiction between maintaining reliability and adapting to specific failure modes.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes control parameters and strategies based on malfunction detection results. When a malfunction is detected in a specific instrument, the control device modifies control contents to account for the degraded state, adjusting operational parameters to match the actual system capabilities while maintaining overall safety and reliability.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If control contents are determined based on malfunction contents and peripheral situation, then appropriateness of control is improved, but device complexity increases

Engineering Contradiction:

Improveappropriateness of controlVSAvoidcontrol system complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control device segments the malfunction handling into distinct processing stages: malfunction detection, malfunction classification, peripheral situation assessment, and control content determination. This segmentation allows the complex adaptive control function to be implemented through modular, manageable components, reducing overall system complexity while maintaining appropriateness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary classification of malfunction types and pre-determines appropriate control strategies for different failure modes. By preparing control content options in advance based on malfunction categories, the system reduces real-time computational complexity while ensuring appropriate control responses are available when needed.

Inventive Principle:

Principle #10Preliminary action

AI summary

A moving object controlling device (10) determines, when malfunction of an instrument such as a processor (11) mounted in a moving object (100) is specified, control contents with respect to the moving object (100) according to malfunction contents such as a level of the specified malfunction and a peripheral situation of the moving object (100) such as a movement place of the moving object (100) and a movement environment that influences movement of the moving object (100). Then, the moving object controlling device (10) controls the moving object (100) according to the determined control contents.
