Solution Overview

Problem

The existing underwater cleaning-work apparatuses have inefficient suctioning of waste water due to the positioning of the suction port above the disk-shaped cleaning body in the cleaning nozzle unit, leading to suboptimal waste water removal efficiency.

Innovation Solution

The apparatus includes a suction port positioned below the cleaning portion and shifted from the cleaning disk on a bottom view, allowing for improved waste water suction efficiency by aligning with the water flow and rotation direction of the cleaning disks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the suction port is disposed above the disk-shaped cleaning body, then the structure is simple, but the suctioning efficiency of waste water is poor

Engineering Contradiction:
Improvesuctioning efficiency of waste waterVSAvoidpositioning configuration
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The suction port is positioned at a location shifted from the cleaning portion on a bottom view, utilizing horizontal spatial offset rather than vertical stacking. This dimensional repositioning allows the suction port to effectively capture waste water generated during cleaning while maintaining structural simplicity, resolving the contradiction between suctioning efficiency and device complexity.

2Productivity

If the suction port is positioned away from the cleaning portion, then the suctioning efficiency improves, but the alignment precision between components decreases

Engineering Contradiction:
Improvewaste water removal efficiencyVSAvoidcomponent alignment
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The suction port is positioned at a specific location shifted from the cleaning portion on the bottom view, creating an optimized local configuration for waste water capture. This localized positioning strategy achieves effective waste water removal while maintaining manageable manufacturing precision requirements, as the offset position is deliberately designed rather than requiring tight alignment.
