Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray nozzle arrangements for cleaning machines require complex fastening mechanisms and flat surfaces, leading to design and assembly challenges, as well as potential contamination from liquid collection in niches and angles.
Innovation Solution
A simplified spray nozzle arrangement with a circular-cylindrical spray shaft and support tube, where the nozzle body is attached via a latching mechanism and seal, eliminating the need for screws and flat surfaces, and allowing for easy assembly and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws or fastening elements are used to attach nozzle bodies to fluid and support tubes, then the connection strength is improved, but the device complexity and assembly difficulty increase
Solution Approach 1:
The patent removes the screw fastening elements from the connection system between nozzle bodies and fluid/support tubes. Instead of using traditional screw connections, the invention employs a direct insertion design where the nozzle body is inserted into a recess in the fluid/support tube and secured by a simple retention ring, thereby eliminating the complexity of screw mechanisms while maintaining connection strength.
Solution Approach 2:
The connection system is divided into separate functional elements: the nozzle body with its insertion portion, the fluid/support tube with its recess, and the retention ring. This segmentation allows each component to be optimized independently and simplifies the assembly process, as the retention ring can be easily installed after the nozzle body is inserted into the recess.
2Stability of the object's composition
If flat surfaces are provided for attaching components, then the attachment stability is improved, but the creation of liquid collection niches and angles increases contamination risk
Solution Approach 1:
The patent employs curved and rounded geometric features throughout the connection interfaces. The nozzle body and fluid/support tube are designed with curved surfaces that eliminate sharp angles and flat resting areas. The retention ring features a curved cross-section that prevents liquid accumulation, while the recess in the fluid/support tube has rounded corners, thereby preventing liquid collection and contamination while maintaining attachment stability.
3Ease of operation
If multiple horizontal surfaces and angles are created for fastening, then the attachment functionality is improved, but the maintenance accessibility and ease of cleaning deteriorate
Solution Approach 1:
The connection system is designed to be dynamically simple, allowing for quick assembly and disassembly. The retention ring can be easily installed or removed from the nozzle body, enabling rapid maintenance and cleaning operations. The simplified connection mechanism eliminates the need for complex fastening procedures, making maintenance accessibility significantly improved while retaining full attachment functionality.
