Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the moving object travels at high speed during water leak inspection, then productivity is improved, but the positional relationship between the ejector and the moving object becomes difficult to maintain

Engineering Contradiction:

Improveinspection speedVSAvoidpositional relationship precision

Core Design Contradiction:

ProductivityVSManufacturing precision

Solution Approach 1:

The control unit dynamically adjusts the travel mode of the moving object and the control mode of the ejector in real-time to maintain the target positional relationship. This includes adjusting ejection pressure, ejection amount, and ejection direction based on the moving object's speed and position, allowing the system to adapt to high-speed travel while maintaining inspection precision.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The control unit continuously monitors the positional relationship between the ejector and the moving object and adjusts the travel mode and ejection parameters accordingly. This feedback mechanism ensures that even at high speeds, the system can maintain the optimal positional relationship for water leak inspection by making real-time corrections.

Inventive Principle:

Principle #23Feedback

2Manufacturing precision

If the ejection pressure is increased to improve inspection effectiveness, then the inspection quality is improved, but the momentum increase of the ejection material causes harmful effects on the moving object

Engineering Contradiction:

Improveinspection qualityVSAvoidejection material momentum

Core Design Contradiction:

Manufacturing precisionVSObject-generated harmful factors

Solution Approach 1:

The control unit adjusts the ejection pressure, ejection amount, and ejection direction as variable parameters based on the moving object's speed and position. By optimizing these parameters dynamically, the system achieves effective water leak inspection while controlling the momentum of the ejection material to prevent harmful effects on the moving object.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The control unit directs the ejection material to specific target portions of the moving object that need inspection, rather than uniform ejection across the entire object. This localized approach improves inspection quality at critical areas while minimizing the overall momentum impact on the moving object.

Inventive Principle:

Principle #3Local quality

3Manufacturing precision

If the ejection amount is increased to ensure complete coverage, then the inspection thoroughness is improved, but the total amount of ejection material consumed increases

Engineering Contradiction:

Improveinspection thoroughnessVSAvoidejection material consumption

Core Design Contradiction:

Manufacturing precisionVSLoss of substance

Solution Approach 1:

The control unit adjusts the ejection amount dynamically based on the moving object's speed and position, applying ejection material only where and when needed for effective inspection. This prevents both insufficient coverage and excessive consumption by matching the ejection amount to the actual inspection requirements.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The control unit maintains continuous adjustment of the ejection parameters throughout the inspection process, ensuring that the ejection material is applied continuously and efficiently as the moving object passes through the inspection area. This continuous control optimizes material usage while ensuring complete coverage of all inspection targets.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

The control device includes: an acquisition unit that acquires moving object information that is information about a moving object in a water leak inspection of a movable body that can travel by unmanned driving; and a control unit that controls at least one of a travel mode of the moving object and a control mode of the ejector according to the moving object information so that a positional relationship between the ejecting device that ejects liquid or gas to the moving object in the water leak inspection and the moving object becomes a predetermined target positional relationship.
