Solution Overview

Problem

Sanitary installation parts, such as valves, face mechanical stress issues due to axial and torsional forces during installation, leading to a risk of housing breakage or deformation, necessitating an enhancement in mechanical strength.

Innovation Solution

The design incorporates support struts with inclined lateral boundaries and varying fastening areas to optimize force transmission, allowing for better absorption of axial and torsional forces, thereby increasing the mechanical strength and resilience of the housing.
