Built-In Shower Arm Filtration for Easy Filter Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing top spray showers with built-in filters face difficulties in replacing the filter element due to their high mounting position, leading to extended water paths, reduced flow rates, and compromised aesthetics.
Innovation Solution
A shower arm structure with a built-in filter element and sealing cap, allowing direct mounting inside the shower arm body, featuring a mounting cavity, water diversion chamber, and switching valve for flexible water outlets, along with magnetic and gasketed fixation for easy replacement and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external filter element is used, then the filter can be replaced easily, but the product appearance is compromised and water flow rate is reduced
Solution Approach 1:
The filter element is merged with the shower arm body by being received within a mounting cavity formed in the shower arm body. This integration eliminates the need for separate external filter housings and additional water pipes, maintaining product appearance simplicity while enabling filter replacement through the detachable sealing cap mechanism.
Solution Approach 2:
The filter element is nested within the mounting cavity of the shower arm body, with the sealing cap providing detachable access. This nested structure allows the filter to be housed inside the main body while still being replaceable, resolving the contradiction between integration and maintainability.
2Reliability
If an external filter element with additional housing is used, then filtration is achieved, but the water path length increases reducing flow rate
Solution Approach 1:
The filter element is merged with the shower arm body structure, eliminating additional housing and extending water pipes. The mounting cavity is formed directly in the shower arm body, creating the most direct water path possible while maintaining effective filtration.
Solution Approach 2:
The filter element is extracted as a separate replaceable component that can be removed through the detachable sealing cap, allowing filtration to be maintained without permanently extending the water path or reducing flow rate.
3Device complexity
If a built-in filter element is used in top spray shower, then product appearance is maintained, but filter replacement becomes difficult due to high mounting position
Solution Approach 1:
The shower arm body is segmented into a mounting cavity that receives the filter element and a detachable sealing cap. This segmentation allows the filter to be integrated into the appearance while providing separate access for replacement through the removable cap, eliminating the need to access high mounting positions.
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
Facilitates easy replacement of the filter element, maintains water flow rate, and preserves product aesthetics by integrating the filter within the shower arm, preventing impurity accumulation and ensuring leak-proof operation.
Implementation Method 1
A first sealing ring is disposed between the filter element and a side wall of the mounting cavity at one end close to the water inlet hole, and a second sealing ring is disposed between the scaling cap and an inner wall of the opening of the mounting cavity.
Implementation Method 2
water in the water inlet hole enters the filter element and is filtered before flowing out
Implementation Method 3
a magnet is built in the magnetic shower holder
