Low-Pressure High-Flow Shower Valve with Rotating Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current temperature control faucets have limited waterway cross-section areas due to their design, resulting in small water crossing areas and low flow rates, which restricts their ability to handle low-pressure high-flow requirements.
Innovation Solution
The design features a fixed part with two water inlets and two water outlets, a temperature control valve with a rotating wall, and a switching valve core that allows for alignment of water inlets and outlets through a single waterway, increasing the water passing area and using a sealing ring for efficient water flow and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional temperature control faucet design with multiple waterways is used, then temperature control function is achieved, but waterway cross-section area is limited and flow rate is low
Solution Approach 1:
The faucet body is divided into separate functional modules: a temperature control module with its own waterway, and a flow control module with separate water inlets and outlets. This segmentation allows each module to be optimized independently, with the flow control module providing a large cross-sectional area for high flow rate while the temperature control module maintains temperature regulation capability.
Solution Approach 2:
The patent transitions from a two-dimensional planar waterway layout to a three-dimensional spatial arrangement. Multiple water inlets and outlets are positioned at different heights and locations on the faucet body, creating vertical and horizontal pathways that increase the effective waterway cross-section area without increasing the horizontal footprint of the faucet.
2Ease of operation
If end face relative rotation switching mechanism is used, then water outlet switching is achieved, but switching port size is small and space requirement is large
Solution Approach 1:
Instead of rotating the valve core relative to the faucet body to switch outlets, the patent inverts the approach by having the faucet body rotate relative to a fixed valve core. This inversion allows the switching ports to remain large and open while achieving the same outlet switching function, eliminating the constraint of small rotating ports.
Solution Approach 2:
The rotating faucet body structure serves multiple functions simultaneously: it acts as both the housing for the temperature control valve and the switching mechanism for selecting different water outlets. This multi-functionality eliminates the need for separate switching components that would require additional space and small ports.
3Volume of moving object
If compact faucet body design is used, then space efficiency is improved, but waterway cross-section area is reduced
Solution Approach 1:
The temperature control valve is nested within the flow control structure, with the temperature control valve body positioned inside the faucet body housing. The waterways of the nested temperature control valve are aligned and connected to the larger waterways of the outer flow control structure, allowing the compact nested design to maintain large effective waterway cross-section areas.

Function Achieved in This Case
This configuration enhances the flow capacity to meet low-pressure high-flow demands while maintaining a compact design and ensuring effective sealing, thus overcoming the limitations of existing faucets.
Implementation Method 1
A sealing ring is arranged between the inner end surface of the water outlet joint part and the circumferential surface of the rotating wall, and the rotating wall is pressed through the sealing ring to play the role of the sealing water wayl
