Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water outlet devices are complex and difficult to use, as they require mechanical structures to switch between weak, broad water jets for irrigation and strong, narrow jets for cleaning, lacking a simple and user-friendly solution for adjustable output.
Innovation Solution
A water outlet device featuring a flexible perforated disc that deforms between concave and convex shapes, allowing for adjustable water jet patterns by moving casings along an axis, with an adjusting nut for precise control and stoppers for protection, enabling easy switching between focused and diverging jets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanical structure is used to switch between weak/broad and strong/narrow water jets, then the device can achieve adjustable water jet patterns, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent employs a flexible perforated disc as the core component to achieve water jet pattern adjustment. The disc can be deformed between a convex shape (for strong, narrow jets) and a concave shape (for weak, broad jets) through simple radial movement. This flexible membrane approach replaces complex mechanical switching mechanisms, reducing device complexity while maintaining adaptability between different water jet patterns.
2Adaptability or versatility
If a complex mechanical structure is used to switch between weak/broad and strong/narrow water jets, then the device can achieve adjustable water jet patterns, but the ease of operation decreases
Solution Approach 1:
The flexible perforated disc enables simple operation through radial movement only. The user can switch between water jet patterns by moving the disc radially, which is much easier than operating complex mechanical structures. This approach significantly improves ease of operation while maintaining full adaptability between different spray patterns.
3Device complexity
If the perforated disc is made flexible and deformable, then the device complexity is reduced, but the manufacturing precision and control over disc shape may worsen
Solution Approach 1:
The flexible perforated disc is designed with specific radial and circumferential stiffness characteristics that allow it to maintain well-defined convex and concave shapes under operational conditions. The disc material and structural design ensure that despite its flexibility, it achieves sufficient shape control for reliable water jet pattern generation, balancing manufacturing precision with structural simplicity.
