Segmented Profile Strip Support for Sanitary Bathtub Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary tub support systems are complex to manufacture, require precise tailoring to tub sizes, and often result in high material costs and weight, with inadequate sound insulation due to large contact areas.
Innovation Solution
The use of profile strips made from rigid foam, which are easily adjustable in length and cross-section, providing a form-fitting support to the C-shaped tub edge, with optional adhesive fixation, and incorporating sound insulation materials for improved soundproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a one-piece foamed tub support is used, then the support structure is simple and easy to install, but the manufacturing process becomes complex requiring different molds for different bathtub sizes
Solution Approach 1:
The support arrangement is divided into multiple profile strips instead of using a single one-piece support. Each profile strip can be manufactured independently using the same mold, eliminating the need for different molds for different bathtub sizes. The profile strips are then assembled to form the complete support structure, achieving both manufacturing simplicity and adaptability to various tub sizes.
2Strength
If a metallic frame support is used, then the support strength is high, but the weight and material costs increase significantly
Solution Approach 1:
The support material is changed from metallic to foamed plastic, fundamentally altering the material parameters. Foamed plastic provides sufficient support strength for bathtub applications while dramatically reducing weight and material costs compared to metallic frames. The profile strip geometry is optimized to achieve the required mechanical properties with the lighter material.
3Stability of the object's composition
If a voluminous molded body support is used, then the support provides large contact area for stability, but sound insulation is reduced due to large contact area
Solution Approach 1:
The support system uses multiple discrete profile strips positioned at specific locations along the bathtub rim rather than a continuous large-contact support. This localizes the support function to specific points while leaving gaps between the strips. The gaps provide sound insulation by reducing the contact area between the bathtub and the support structure, while the strategically positioned strips maintain installation stability.
