A fitting body with a base body and cover forming a water path, featuring a laterally open channel and an elastic membrane that forms an air cushion, allowing for sound absorption and pressure minimization without requiring maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If soundproofing components are installed in concealed fittings with limited space, then noise reduction is achieved, but the components are prone to backwash and require maintenance
Solution Approach 1:
The fitting body is divided into functional zones: a water pathway for water flow and a damping chamber for soundproofing. The membrane separates these zones, allowing the damping chamber to be filled with damping material while keeping the water pathway clear. This segmentation enables independent optimization of each function and prevents water from entering the damping chamber, eliminating backwash issues.
Solution Approach 2:
A membrane acts as an intermediary barrier between the water pathway and the damping chamber. This membrane prevents water from entering the damping chamber while allowing sound vibrations to be dampened, thus protecting the damping material from backwash and eliminating maintenance requirements.
2Object-affected harmful factors
If damping material is placed in the water pathway, then soundproofing effectiveness is improved, but flow resistance increases
Solution Approach 1:
The fitting body is divided into functional zones: a water pathway for water flow and a damping chamber for soundproofing. The membrane separates these zones, allowing the damping chamber to be filled with damping material while keeping the water pathway clear. This segmentation enables independent optimization of each function and prevents water from entering the damping chamber, eliminating backwash issues.
Solution Approach 2:
The damping material is extracted from the water pathway and placed in a separate damping chamber. This extraction eliminates the flow resistance caused by damping material in the water pathway while maintaining soundproofing effectiveness, as the damping chamber is acoustically coupled to the water pathway through the membrane.
3Object-affected harmful factors
If soundproofing components are installed in surface-mounted fittings, then noise reduction is achieved, but installation space is limited
Solution Approach 1:
The damping chamber utilizes the vertical dimension by extending downward from the water pathway. This allows the damping material to be positioned in the vertical space below the water pathway, effectively using installation space that would otherwise be unused and enabling soundproofing in space-constrained applications.
