Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the cleaning device operates continuously without monitoring, then productivity is maintained, but reliability deteriorates due to undetected abnormalities

Engineering Contradiction:
Improvedetection of abnormalitiesVSAvoidmonitoring system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The cleaning device monitors its own operating state through sensors that detect abnormalities in real-time. The control unit automatically identifies issues such as brush roll jams, motor failures, or unusual vibrations without external intervention, enabling the system to self-diagnose and alert the user, thus improving reliability without requiring complex external monitoring infrastructure

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system continuously collects state information from multiple sensors and provides feedback to the control unit, which compares actual performance against normal operating parameters. When deviations are detected, the system generates alerts or warnings to notify the user, creating a closed-loop monitoring system that enhances reliability through automated feedback mechanisms

Inventive Principle:
Principle #23Feedback

2Measurement precision

If multiple sensors are added to monitor all components, then measurement precision improves, but device complexity increases

Engineering Contradiction:
Improvestate information detectionVSAvoidsensor system
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent employs multi-functional sensors that can detect multiple types of abnormalities simultaneously. For example, acceleration sensors can detect both vibrations indicating mechanical issues and tilts indicating improper placement, while current sensors can monitor both motor performance and brush roll resistance. This universal approach allows comprehensive monitoring with fewer sensor types, balancing measurement precision with device complexity

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

Solution Approach 2:

The control unit integrates data from multiple sensors and combines their functions to achieve comprehensive monitoring. Rather than having separate dedicated sensors for each parameter, the system merges sensor inputs and uses intelligent algorithms to detect various abnormalities, reducing the total number of components while maintaining high measurement precision through data fusion

Inventive Principle:
Principle #5Merging (Combining)
