Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fixed-structure cleaning heads are used, then the structure is simple and easy to manufacture, but they cannot efficiently clean curbs and raised surfaces, requiring multiple passes
Solution Approach 1:
The cleaning head is divided into multiple sections (first section, second section, third section) that can independently pivot relative to each other. This segmentation allows each section to adapt to different angles of curbs and raised surfaces, enabling efficient single-pass cleaning while maintaining a relatively simple overall structure based on conventional cleaning head components.
Solution Approach 2:
The cleaning head incorporates pivoting mechanisms with pins and slots that allow the sections to dynamically adjust their angles. This dynamic capability enables the cleaning head to adapt to various curb configurations and raised surfaces, improving cleaning efficiency without requiring a completely complex fixed-structure design for each scenario.
2Ease of operation
If conventional cleaning heads are used on curbs, then multiple passes are required to achieve thorough cleaning, but this increases the time and effort needed
Solution Approach 1:
By dividing the cleaning head into multiple independently pivoting sections, each section can be positioned to optimally clean different portions of curbs and raised surfaces in a single pass, eliminating the need for multiple passes and reducing both time and operational effort.
Solution Approach 2:
The pivoting sections can change their angular parameters to match the geometry of curbs and raised surfaces. This parameter adjustment capability allows the cleaning head to maintain effective contact and spray angle across varied surfaces, enabling thorough cleaning in one pass and reducing overall cleaning time.
3Adaptability or versatility
If a fixed-structure cleaning head is used, then the device is simple to manufacture, but it lacks adaptability to different surface angles and shapes
Solution Approach 1:
The cleaning head is segmented into multiple sections connected by pivoting mechanisms, allowing each section to independently adapt to different surface angles. This segmentation provides versatility for cleaning various surface geometries while keeping each individual section relatively simple in structure.
Solution Approach 2:
The dynamic pivoting capability of the sections allows the cleaning head to adapt to different surface angles and shapes. The pins and slots mechanism enables controlled movement that provides versatility without requiring overly complex structural components, balancing adaptability with manufacturability.
