Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional filtering cartridges are used with fixed lids, then filtration is achieved, but maintenance time increases and maintenance costs increase
Solution Approach 1:
The filtering system is segmented into multiple rotating filtering discs instead of a single cartridge, allowing one disc to be cleaned while others remain in operation. This segmentation enables continuous filtration during maintenance cycles.
Solution Approach 2:
The system implements periodic cleaning cycles where filtering discs are automatically cleaned at predetermined intervals without stopping the hydraulic circuit operation. The electronic control unit manages these periodic maintenance actions.
2Productivity
If traditional filtering cartridges are used, then filtration is achieved, but pressure drop increases due to dirt accumulation
Solution Approach 1:
The hydraulic circuit maintains continuous operation without pressure drops by automatically cleaning filtering discs during rotation. The water jet cleaning system removes accumulated dirt before it causes significant pressure drops.
Solution Approach 2:
The filtering discs clean themselves through the automatic water jet cleaning system while rotating in place. The system performs self-maintenance without requiring removal or manual intervention.
3Adaptability or versatility
If multiple models of filtering apparatus are produced, then adaptability to various hydraulic circuits is improved, but production costs increase and storage requirements increase
Solution Approach 1:
The apparatus achieves universality by allowing different numbers of filtering discs to be installed on a single standardized platform. The same basic structure can accommodate various configurations to suit different hydraulic circuit requirements.
Solution Approach 2:
The system is made dynamic and adaptable by allowing the number of filtering discs to be adjusted based on specific application needs. This configurability eliminates the need for multiple fixed models.
