Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a robot cleaner uses fixed cleaning algorithms, then the device complexity is reduced, but the adaptability to different cleaning environments deteriorates

Engineering Contradiction:
Improveadaptability to cleaning environmentsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The robot cleaner dynamically selects from multiple pre-stored cleaning algorithms based on real-time image analysis results. The controller switches between different cleaning patterns (e.g., random movement, systematic scanning, obstacle avoidance) according to the detected environment type, making the cleaning system adaptive without requiring complex real-time algorithm generation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Multiple cleaning algorithms are pre-stored in the controller before operation. The system performs preliminary preparation by storing various cleaning patterns and selecting the appropriate one based on image analysis, rather than generating cleaning algorithms on-the-fly during operation.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the robot cleaner captures and analyzes image information, then the cleaning performance is improved, but the energy consumption increases

Engineering Contradiction:
Improvecleaning performanceVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The image sensor captures images at periodic intervals or at specific triggering moments during cleaning operation, rather than continuously. The controller analyzes these periodic images to determine environment type and adjust cleaning algorithms accordingly, reducing energy consumption compared to continuous image capture and analysis.
