Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional cleaning devices are used, then dust on the surface inside the hub can be cleaned, but oil contaminants with stronger adhesion cannot be removed
Solution Approach 1:
The patent combines dust cleaning function and oil contaminant removal function into a single integrated device. The cleaning assembly includes both dust suction nozzles and oil removal spray nozzles, allowing simultaneous or sequential operation of both functions without requiring separate manual interventions.
Solution Approach 2:
The cleaning device is designed with multi-functionality to handle different types of contaminants. It can switch between dust suction mode and oil removal mode through the switching assembly, making it a universal cleaning solution for both dry and oily contaminants in the hub interior.
2Object-affected harmful factors
If manual spraying of oil removal agents and manual lubrication is used, then oil contaminants can be removed, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The device enables automated oil removal through the switching assembly that automatically activates the oil removal spray nozzle and controls the spray timing. The system performs self-service by automatically switching between cleaning modes and executing the oil removal process without continuous manual intervention, thereby improving productivity.
Solution Approach 2:
The switching assembly enables continuous operation by seamlessly transitioning between dust cleaning and oil removal modes. The automated switching mechanism ensures that the cleaning process continues without interruption or idle time, maintaining productive action throughout the maintenance cycle.
3Reliability
If manual lubrication and maintenance of transmission components is performed, then components can be maintained, but the process is time-consuming and inefficient
Solution Approach 1:
The device incorporates an automated lubrication function where the lubrication assembly dispenses lubricant to transmission components automatically. The switching assembly coordinates the lubrication process, enabling the system to perform self-maintenance without requiring manual intervention for lubrication application, thus reducing maintenance time while ensuring reliability.
4Adaptability or versatility
If a simple dust cleaning device is used, then the device structure remains simple, but it cannot perform automated oil removal and lubrication functions
Solution Approach 1:
The device is segmented into distinct functional modules: a cleaning assembly for dust removal, an oil removal assembly with spray nozzles, a lubrication assembly, and a switching assembly. This modular segmentation allows each component to perform its specific function while maintaining overall system manageability and reducing the complexity burden of multi-functionality.
Solution Approach 2:
The switching assembly introduces dynamic control to the device, enabling it to adapt its configuration and function based on the cleaning needs. The switching mechanism dynamically activates or deactivates specific assemblies (dust cleaning, oil removal, lubrication) as required, providing adaptability without permanently increasing structural complexity.
