Dual-Path Toilet Spray Head for Stable Drainage Under Variable Pressure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spray heads with single water paths struggle to maintain effective drainage under varying water pressures, leading to noise issues at high pressure and poor performance at low pressure, and require high-power pumps that fail during power outages.
Innovation Solution
A spray head with dual water paths of differing flow areas, adaptable to different water pressures, and a flushing system with separate water supply assemblies for each path, ensuring consistent drainage performance across varying conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single water path spray head is used, then the device complexity is reduced, but the drainage performance becomes inconsistent under varying water pressures
Solution Approach 1:
The spray head is divided into multiple water paths (first water path and second water path) with different flow areas. Each water path is independently configured to handle different water pressure conditions, allowing the system to adapt to varying pressures without requiring a completely different device design.
Solution Approach 2:
Different segments of the spray head (different water paths) are designed with different local characteristics - specifically different flow areas. The first water path has a first flow area while the second water path has a second flow area, enabling each segment to optimize performance for specific pressure ranges.
2Speed
If high water pressure is used for drainage, then the drainage speed increases, but noise levels increase and pump power requirements increase
Solution Approach 1:
The system changes the flow area parameter of the water path based on operating conditions. By selecting appropriate water paths with different flow areas, the system can achieve effective drainage at lower pressures, thereby reducing noise generation while maintaining drainage speed.
3Reliability
If high-power pumps are used to ensure drainage during power outages, then the drainage capability under normal conditions improves, but energy consumption increases and reliability during power outages decreases
Solution Approach 1:
The spray head system is designed to utilize the existing water pressure from the building's water supply system without requiring additional pumping power. By properly configuring multiple water paths with different flow areas, the system self-adjusts to maintain drainage capability across varying pressure conditions, eliminating the need for high-power pumps and their associated energy consumption and failure risks.
