Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing suction nozzle devices lack optimized suction properties and versatility in adapting to different surface sizes and types, with complex designs and flow path irregularities leading to inefficiencies in cleaning operations.
Innovation Solution
A suction nozzle device with a rotatable suction head mounted inside a housing, featuring a structurally simple design with a fixed axis of rotation relative to the spray nozzle, allowing for adjustable angular positions and easy detachment/replacement of suction heads, which includes guide skids and a sliding seal for minimized flow losses and adaptable cleaning capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the suction head is mounted inside the housing of the suction body, then the suction head is protected and the pivot bearing can be designed in a structurally simple manner, but the device complexity increases due to the internal mounting arrangement
Solution Approach 1:
The suction head is nested inside the housing of the suction body, with the suction head positioned between the first wall and the second wall of the housing. This nesting arrangement protects the suction head while allowing for a compact and relatively simple overall structure.
2Volume of moving object
If the suction head is positioned at a minimum distance from the surface to be cleaned, then the design is optimized for compactness, but the suction performance may be reduced due to limited contact area
Solution Approach 1:
The suction head is positioned at a minimum distance from the surface to be cleaned, which is essentially half the diameter of the suction head. This positioning optimizes the compactness of the device while maintaining effective suction performance through the strategic placement of the suction opening on the suction head.
3Ease of operation
If the suction head is made detachable and reinsertable without tools, then the ease of maintenance and replacement is improved, but the reliability of the connection may be reduced
Solution Approach 1:
The suction head is designed as a detachable component that can be removed and reinserted without tools. The suction head includes a suction opening in fluid communication with the connection, allowing for easy separation and reassembly while maintaining functional integrity.
4Adaptability or versatility
If the suction head is rotatable on the suction body, then the adaptability to different surface sizes and operator sizes is improved, but the device complexity increases due to the rotational mechanism
Solution Approach 1:
The suction head is rotatably mounted on the suction body about an axis of rotation. This dynamic mounting allows the suction head to be rotated to different angular positions, enabling adaptation to different surface sizes and operator sizes while maintaining a relatively simple pivot bearing design.
5Productivity
If the fluid path for suction is designed to minimize jumps in cross section, then the suction efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The housing and suction head are designed with specific geometric parameters that minimize jumps in cross section along the fluid path for suction. The suction head is positioned between the first wall and the second wall of the housing, with the suction opening in fluid communication with the connection, creating a smooth flow path that optimizes suction efficiency.
