Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If mobile scanners are used to measure refractory lining, then measurement capability is improved, but operator safety deteriorates due to exposure to harsh environments and high heat

Engineering Contradiction:
Improverefractory lining measurementVSAvoidheat exposure and safety risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an autonomous mobile scanner as an intermediary device that performs measurements remotely. The scanner includes a laser range finder and positioning system that enables it to autonomously navigate and measure refractory lining without human operators being exposed to high heat and harsh environments. The scanner acts as a mediator between the measurement objective and the operator, eliminating direct exposure to harmful conditions.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces manual mechanical operations with an autonomous robotic system. The mobile scanner uses automated navigation, laser ranging, and computer-controlled measurement processes instead of manual positioning and measurement techniques. This substitution eliminates the need for operators to physically position equipment and take measurements in hazardous environments, improving safety while maintaining measurement precision.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If autonomous scanners are implemented, then operator safety is improved by reducing exposure, but device complexity increases due to automation requirements

Engineering Contradiction:
Improveoperator safetyVSAvoidscanner system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The autonomous mobile scanner is designed as a multi-functional integrated system that combines navigation, positioning, laser ranging, and data processing capabilities in a single device. This universal design allows the scanner to perform multiple functions autonomously, reducing the need for separate specialized equipment and operators, thereby managing complexity through consolidation rather than multiplication of components.

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

Solution Approach 2:

The mobile scanner is equipped with autonomous navigation and self-positioning capabilities that enable it to operate independently without human intervention. The system uses onboard sensors, positioning systems, and control algorithms to navigate to measurement locations, position itself correctly, and execute measurements automatically. This self-service capability reduces operational complexity by eliminating the need for manual control while maintaining safety.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If manual positioning and scanning is performed, then ease of operation is maintained, but productivity decreases due to time-consuming procedures and operator intervention

Engineering Contradiction:

Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The autonomous mobile scanner is pre-programmed with measurement protocols, navigation paths, and positioning algorithms that enable it to autonomously execute measurement tasks without real-time human intervention. The system prepares and positions itself automatically before measurements begin, and continues operations autonomously throughout the measurement process. This preliminary automation of operations maintains ease of use while dramatically improving productivity by eliminating manual positioning and measurement time.

Inventive Principle:
Principle #10Preliminary action
