Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If automated cleaning systems use fixed, predefined spray patterns, then the cleaning process is standardized and reproducible, but the systems cannot adapt to varying local contamination conditions, leading to oversizing and inefficient resource usage
Solution Approach 1:
The cleaning system dynamically adjusts the spray pattern and nozzle positions based on real-time contamination detection. The manipulator device moves nozzles to different locations and orientations, transforming a static cleaning system into a dynamic one that adapts to the actual soiling conditions, thereby resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The system incorporates sensors that detect contamination levels and provide feedback to the control unit. This feedback loop enables the system to adjust cleaning parameters (spray pattern, nozzle position, cleaning agent application) based on actual contamination conditions, achieving adaptability while maintaining manageable complexity through automated control.
2Reliability
If cleaning systems are oversized with safety margins for worst-case scenarios, then cleaning reliability is improved, but resource consumption (water, energy, time) increases significantly
Solution Approach 1:
The system applies cleaning resources locally and selectively to areas with detected contamination rather than uniformly across the entire surface. The manipulator device positions nozzles precisely at contaminated locations, and the spray pattern is adjusted to target specific soiling areas, thereby maintaining cleaning reliability while dramatically reducing water and energy consumption.
Solution Approach 2:
The system changes cleaning parameters (spray intensity, duration, nozzle position, cleaning agent concentration) based on the detected contamination level and type. This parameter adaptation allows the system to achieve reliable cleaning with minimal resource input by matching cleaning intensity to actual contamination severity rather than using fixed high-intensity parameters.
3Productivity
If cleaning systems lack sensors for detecting local contamination, then the system structure remains simple, but the cleaning process cannot be optimized and excessive cleaning time is spent on already clean areas
Solution Approach 1:
The cleaning system performs self-diagnosis and self-adjustment through integrated contamination sensors. The sensors automatically detect soiling conditions, and the control unit autonomously adjusts the cleaning process without external intervention, thereby improving productivity while managing complexity through automated self-service functionality.
Solution Approach 2:
The sensor system serves multiple functions: detecting contamination presence, determining contamination level, identifying contamination type, and monitoring cleaning progress. This multi-functionality justifies the added complexity by providing comprehensive data that enables significant productivity improvements through optimized cleaning resource allocation.
4Adaptability or versatility
If the nozzle is fixed in position on the rotary head, then the mechanical structure is simpler, but the jet cannot be directed in all directions to clean complex geometries
Solution Approach 1:
The nozzle is mounted on a manipulator device that provides dynamic positioning and orientation control. The manipulator can move the nozzle to different locations and rotate it to point in various directions, transforming a static nozzle arrangement into a dynamic one capable of accessing complex geometries while maintaining manageable structural complexity through modular design.
