Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple individual charging and cleaning stations are deployed for autonomous floor cleaning units, then each unit can be independently serviced, but the system becomes expensive and requires significant space

Engineering Contradiction:
Improveservice availabilityVSAvoidspace occupied
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

Multiple charging stations are merged into a single shared cleaning station that serves multiple autonomous floor cleaning units. The cleaning station includes a common cleaning area where multiple units can be sequentially cleaned, and a shared water tank that is distributed among the units. This consolidation reduces the total space required while maintaining service availability for multiple units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cleaning station is designed as a universal facility that can service multiple different autonomous floor cleaning units. The station includes adjustable components and a flexible cleaning area that can accommodate different unit types and sizes. A single station performs the functions of multiple individual stations, making the system more space-efficient while maintaining versatility.

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

2Ease of operation

If multiple individual charging and cleaning stations are deployed, then each unit has dedicated service, but personnel costs and maintenance workload increase

Engineering Contradiction:
Improveservice qualityVSAvoidmaintenance efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

Multiple charging stations are merged into a single shared cleaning station that serves multiple autonomous floor cleaning units. The cleaning station includes a common cleaning area where multiple units can be sequentially cleaned, and a shared water tank that is distributed among the units. This consolidation reduces the total space required while maintaining service availability for multiple units.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements automated sequencing and control where the cleaning station autonomously manages the cleaning process for multiple units. The station can identify which units need cleaning, sequence them appropriately, and execute the cleaning process with minimal human intervention, reducing personnel workload while maintaining service quality.

Inventive Principle:
Principle #25Self-service

3Area of stationary object

If a shared cleaning station serves multiple floor cleaning units, then space and costs are reduced, but coordination and sequencing become necessary

Engineering Contradiction:

Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The cleaning station includes sensors and control systems that monitor the status of multiple autonomous floor cleaning units. The system receives feedback about which units need cleaning, their current locations, and their operational status. Based on this feedback, the control system automatically sequences the cleaning process and manages the water distribution, reducing the complexity of manual coordination.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system implements automated sequencing and control where the cleaning station autonomously manages the cleaning process for multiple units. The station can identify which units need cleaning, sequence them appropriately, and execute the cleaning process with minimal human intervention, reducing personnel workload while maintaining service quality.

Inventive Principle:
