Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cleaning module is fixed relative to the main body, then the structure is simple and stable, but the adaptability to various cleaning scenarios is poor
Solution Approach 1:
The cleaning module is made dynamically adjustable relative to the main body through a lifting mechanism. The module can be raised or lowered along the shaft axis to adapt to different cleaning scenarios, transforming a static structure into a dynamic one that responds to varying operational requirements.
Solution Approach 2:
The cleaning assembly is segmented into separable components: the main body, the shaft, and the cleaning module. This segmentation allows the cleaning module to be independently positioned and adjusted along the shaft, enabling adaptability while maintaining overall structural coherence.
2Adaptability or versatility
If a lifting mechanism is added to allow the cleaning module to move axially, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The lifting mechanism is merged with the existing shaft structure. The cleaning module is configured to slide along the shaft axis, integrating the lifting function into the shaft itself rather than adding a completely separate mechanism, thereby reducing overall complexity.
Solution Approach 2:
The shaft serves multiple functions: it provides structural support, transmits rotation from the motor, and enables axial movement of the cleaning module. This multi-functionality reduces the need for additional dedicated components, simplifying the overall mechanism.
3Manufacturing precision
If high-precision shaft processing is used to enable axial movement, then the positioning accuracy is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The cleaning module is designed to self-align and self-position along the shaft through its own structural features. The module's geometry and the shaft's features work together to guide positioning without requiring ultra-precise machining, allowing standard manufacturing tolerances to achieve adequate positioning accuracy.
Solution Approach 2:
Instead of investing in high-precision shaft processing, the design uses simpler, more economical manufacturing methods for the shaft and cleaning module. The positioning is achieved through functional design rather than precision machining, reducing manufacturing costs and complexity.
