Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single cleaning roller and single dispensing member are used, then the device complexity is reduced, but the adaptability for cleaning in multiple directions and tight spaces deteriorates
Solution Approach 1:
The cleaning head is segmented into multiple independent cleaning rollers (first cleaning roller, second cleaning roller) that can be independently rotated by separate drive assemblies. This segmentation allows each roller to be independently controlled to clean different directions and areas, including tight spaces, without requiring a completely redesigned complex structure.
Solution Approach 2:
The cleaning head is designed with multiple dispensing members (first dispensing member, second dispensing member) that can deliver solution in different directions. This multi-functionality allows the single cleaning head to adapt to various cleaning scenarios including different directions and tight spaces, maintaining versatility while managing complexity through integrated design.
2Ease of operation
If the cleaning head is fixed to the body, then the structural stability is improved, but the ease of operation for reaching tight spaces deteriorates
Solution Approach 1:
The cleaning head is pivotally connected to the body rather than being fixed, allowing it to rotate and adjust its position dynamically. This dynamic connection enables the cleaning head to reach tight spaces and adjust to different cleaning angles while maintaining structural stability through the pivotal connection mechanism that provides controlled movement.
3Productivity
If solution is delivered only in front of the cleaning head, then the device complexity is reduced, but the productivity for comprehensive surface coverage deteriorates
Solution Approach 1:
The liquid distribution system is segmented into multiple dispensing members positioned at different locations on the cleaning head. The first dispensing member delivers solution in a first direction beyond the first side, while the second dispensing member delivers solution in a second direction beyond the second side, enabling comprehensive surface coverage without requiring a single complex distributed system.
Solution Approach 2:
The liquid distribution system extends solution delivery beyond the front of the cleaning head to lateral directions. The dispensing members are positioned to deliver solution laterally beyond the sides of the cleaning head, adding dimensional coverage that improves productivity for comprehensive surface coverage while managing complexity through strategic positioning.
4Adaptability or versatility
If cleaning rollers are positioned only at the front, then the device complexity is reduced, but the adaptability for edge and corner cleaning deteriorates
Solution Approach 1:
The cleaning rollers are segmented and positioned at different locations including the front and sides of the cleaning head. This segmentation allows specific rollers to be positioned for edge and corner cleaning while maintaining manageable device complexity through modular positioning arrangements.
Solution Approach 2:
Different cleaning rollers are positioned at different locations on the cleaning head to address specific cleaning needs. The first cleaning roller and second cleaning roller are positioned to handle different areas including edges and corners, providing local quality optimization without requiring complex repositioning mechanisms.
