Ceramic Nozzle Axial Adjustment for Channel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceramic nozzle covers for sanitary cleaning devices often experience dimensional deviations during manufacturing, making precise positioning of channel-forming members challenging due to axial dimensional discrepancies.
Innovation Solution
The nozzle design incorporates a ceramic nozzle cover with adjustable rear-side and distal-side channel-forming components, allowing for axial positioning adjustments to align with the nozzle cover's reference surface and engage with protrusions, ensuring accurate alignment and sealing despite manufacturing deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a ceramic nozzle cover is used, then the nozzle has high durability and hygiene properties, but dimensional deviations occur during manufacturing making precise positioning difficult
Solution Approach 1:
The channel-forming member is designed with axial adjustability, allowing it to move along the nozzle cover's axial direction. This dynamic positioning capability enables the channel-forming member to compensate for dimensional deviations in the ceramic nozzle cover, achieving precise alignment of water ejection openings despite manufacturing variations.
Solution Approach 2:
The invention changes the positional parameter of the channel-forming member along the axial direction. By allowing adjustment of the channel-forming member's position, the system can adapt to variations in the nozzle cover's dimensions and achieve proper alignment without requiring ultra-precise manufacturing of the ceramic component.
2Manufacturing precision
If highly precise positioning is required for channel-forming member, then water ejection alignment is improved, but assembly complexity and difficulty increase
Solution Approach 1:
The channel-forming member incorporates axial movement capability, transforming a static positioning problem into a dynamic adjustment problem. This allows the assembly process to be simpler since the channel-forming member can be inserted in a range of positions and then adjusted to the correct alignment, rather than requiring precise positioning during initial assembly.
Solution Approach 2:
The nozzle cover is provided with a reference surface that establishes a predetermined axial position. This reference surface enables preliminary positioning of the channel-forming member, after which fine adjustment can be made. This two-stage approach simplifies assembly by providing an initial alignment reference while still allowing for precise final positioning.
