Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional WCs generate excessive noise during flushing operations due to the loud sound of water discharge, which is a significant concern in environments like hotels with multiple bathrooms, impacting accommodation quality.
Innovation Solution
A WC design featuring a single-piece ceramic structure with a discharge duct and a supply duct that narrows from a flowing portion to an outlet portion, combined with an asymmetric lateral wall and a single flushing opening, which reduces noise by creating a spiral flow and minimizing water impact, ensuring effective flushing and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional WC flushing systems are used, then flushing function is provided, but excessive noise is generated during flushing operations
Solution Approach 1:
The supply duct incorporates a narrowing section that changes the cross-sectional area parameter along the water flow path. This gradual reduction in flow area modifies the water flow velocity and pressure distribution, creating a controlled spiral flow pattern that reduces impact noise while maintaining effective flushing function
Solution Approach 2:
The asymmetric lateral wall and narrowing section of the supply duct create curved flow paths that generate spiral water flow. This curvature in the flow path causes the water to rotate before entering the basin, reducing direct impact and associated noise while preserving flushing effectiveness
2Object-affected harmful factors
If multiple flushing openings are used, then flushing coverage is improved, but noise and complexity increase
Solution Approach 1:
The WC employs a single flushing opening positioned on the lateral wall of the narrowing section, combined with an asymmetric lateral wall configuration in the basin. This asymmetric design creates an optimized spiral flow pattern from the single opening that achieves effective flushing coverage without the noise and complexity associated with multiple openings
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively reduces noise levels during flushing while maintaining high efficiency in cleaning the inner walls and enhancing hygiene through the rimless design.
Implementation Method 1
the outlet portion 9 comprises a bottom wall 11 inclined upwards with respect to the axis X. The inclined position of the bottom wall 11 causes the outlet portion 9 to extend beyond the flushing opening 6. In this way a diminished load of the flow of the flushing water occurs which further facilitates the effectiveness of the present invention.
