U-Shaped Expansion Tank Bracket With Weld-Bead Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing thermal expansion tanks in plumbing systems are cumbersome, unsafe, and non-compliant with building codes, lacking a standardized and efficient solution for mounting these devices to building surfaces, which can lead to vibration and movement-related damage.
Innovation Solution
A U-shaped bracket assembly with aligned slots and hose clamp straps that encircle the tank, providing a secure and adjustable mounting system for cylindrical devices, including thermal expansion tanks, using a back and side walls with notches to engage the tank's weld bead and prevent vertical movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting methods are used for thermal expansion tanks, then the tanks can be secured to building surfaces, but the mounting process becomes cumbersome and unsafe while violating building codes
Solution Approach 1:
The mounting system is divided into separate functional components: a U-shaped bracket for structural support, hose clamp straps for secure attachment, and weld bead engagement features for positioning. This segmentation allows each component to be optimized for its specific function while simplifying the overall installation process and improving safety compliance
Solution Approach 2:
The U-shaped bracket acts as an intermediary element between the building surface and the thermal expansion tank. It provides a standardized mounting interface that distributes loads properly and ensures code-compliant attachment, eliminating the need for improper direct mounting methods
2Reliability
If large brackets with bottom shelves are used to support expansion tanks, then the tanks are securely mounted, but the brackets become cumbersome to install and use
Solution Approach 1:
The mounting system incorporates adjustable features including slots in the side walls that allow for flexible positioning of the hose clamp straps. This dynamic adjustment capability enables installers to accommodate various tank sizes and positions while maintaining secure mounting, eliminating the need for fixed, cumbersome bracket designs
Solution Approach 2:
The traditional bottom shelf support is extracted and replaced with side-wall-based hose clamp straps that encircle the tank. This removes the cumbersome horizontal support structure while maintaining secure mounting through vertical clamping action, simplifying both the bracket design and installation process
3Reliability
If standardized mounting systems are implemented for thermal expansion tanks, then building code compliance is achieved, but the system requires precise engagement features for weld beads
Solution Approach 1:
The bracket incorporates localized engagement features specifically at the side wall edges where weld beads will be positioned. These notches or engagement surfaces are precisely formed only where needed to interface with the weld bead, while the rest of the bracket maintains standard manufacturing tolerances. This localized precision approach ensures code compliance without requiring high precision throughout the entire component

AI summary
An expansion tank is fastened to a support using a bracket with a U-shaped cross-section formed by a back and two sidewalls. The edges of the sidewalls each have a notch mating with a weld bead on the tank. Fasteners hold the back of the bracket to the support. First and second hose clamps pass through the sidewalls by the back to encircle the tank and clamp it to the edges of the sidewall when the hose clamps are tightened.
