Shower Channel Installation Kit with Sound-Decoupled Substructure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shower channel installation kits face challenges in achieving structural stability, tightness, and sound reduction while maintaining simplicity in installation, as they often result in cavities, water penetration, and sound bridges due to the direct contact of height-adjustable feet with the relining material.
Innovation Solution
The solution involves a shower channel installation kit with height-adjustable feet attached to a substructure rather than the channel itself, using internally threaded sleeves for deeper attachment points and sound-insulating materials, along with a sealing and crack-bridging fleece to ensure stability and sound decoupling, and a profile rail for improved fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If height-adjustable feet are attached directly to the shower channel, then the installation height can be adjusted, but sound bridges are created between the metallic components and the relining material
Solution Approach 1:
A plastic substructure is introduced as an intermediary component between the metallic shower channel and the relining material. This substructure serves as a sound-insulating barrier that prevents direct contact between metal components and the relining material, thereby eliminating sound bridges while still allowing height adjustment functionality through integrated feet.
Solution Approach 2:
The solution employs composite construction by combining metallic shower channel components with a plastic substructure. The plastic material provides sound insulation properties while the metallic components maintain structural integrity and drainage functionality, creating a multi-material assembly that addresses both structural and acoustic requirements.
2Ease of manufacture
If threaded rods are attached higher on the shower channel, then installation is simpler, but the attachment stability and alignment during installation deteriorate
Solution Approach 1:
The attachment points for height adjustment are relocated from the vertical dimension (attached to the channel body) to the horizontal dimension (integrated into the substructure base). This dimensional shift allows threaded rods to engage with the substructure at optimal locations that provide both stability and alignment control during installation.
3Device complexity
If the shower channel is directly lined with cement or relining material, then the installation process is simpler, but cavities form between the channel and the relining material compromising structural stability
Solution Approach 1:
The plastic substructure acts as an intermediary layer between the shower channel and the relining material, providing a continuous bonding surface that prevents cavity formation. This substructure ensures complete filling of the space between the channel and relining material with padding, achieving full structural stability without complicating the installation process.
4Manufacturing precision
If height-adjustable feet are used for alignment, then the shower channel can be leveled properly, but sound bridges are created through the threaded rods contacting the relining material
Solution Approach 1:
The plastic substructure serves as a sound-insulating intermediary that intercepts the sound transmission path from the metallic shower channel to the relining material. The height-adjustable feet are integrated into this substructure, allowing precise leveling while the plastic material blocks sound transmission through the threaded rods.
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
This configuration enhances stability and tightness, minimizes sound transmission, and prevents water penetration, while maintaining a simple installation process by using internally threaded sleeves and sound-insulating materials, ensuring a stable and watertight shower channel arrangement.
Implementation Method 1
The height-adjustable threaded feet comprise on the underside of the threaded rod preferably rotatably arranged foot sockets with sound-insulating material inserts arranged on the underside. This sound decoupling mat is placed on the screed or raw concrete of the wet room.
