Solution Overview

Problem

Existing mounting systems for fluid-carrying installations require complex on-site assembly of multiple loose components, leading to increased installation time, risk of component loss, and impractical handling for installers.

Innovation Solution

The insulating element is pre-fixed to the wall bracket with a plug-in element, such as a mushroom-shaped protuberance, ensuring it is in the correct position during assembly, and fastening elements are connected to the insulating element, allowing for easy attachment and reducing the risk of loss by being frictionally connected and easily separable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple loose components are provided separately, then the mounting system offers flexibility and ease of assembly, but the risk of component loss increases and handling becomes impractical

Engineering Contradiction:
Improvehandling convenienceVSAvoidcomponent loss
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent combines multiple loose components (insulating element, fastening elements, wall bracket) into a single integrated mounting system where components are pre-assembled and connected. The insulating element is frictionally connected to the wall bracket, and fastening elements are attached to the insulating element, creating a unified assembly that eliminates the need to handle separate loose parts during installation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The components are pre-assembled and pre-positioned during manufacturing. The insulating element is pre-connected to the wall bracket with proper frictional engagement, and fastening elements are pre-attached to the insulating element. This preliminary assembly ensures that during on-site installation, the components are already in their correct positions and orientations, eliminating the need for searching or repositioning.

Inventive Principle:
Principle #10Preliminary action

2Loss of time

If components are pre-fixed together, then the risk of component loss is reduced and assembly is simplified, but the ability to adjust individual components is limited

Engineering Contradiction:
Improveassembly timeVSAvoidcomponent adjustability
Core Design Contradiction:
Loss of timeVSAdaptability or versatility

Solution Approach 1:

The mounting system incorporates dynamic characteristics through the frictional connection between the insulating element and wall bracket, and between fastening elements and insulating element. These frictional connections allow for controlled movement and adjustment during installation while maintaining secure attachment during operation. The system transitions from a rigid pre-fixed state to a controllable adjustment state and back to a stable installed state.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

While the system is pre-assembled as a unit, it maintains segmentable connections through the frictional interfaces. The fastening elements can be detached from the insulating element, and the insulating element can be separated from the wall bracket if needed. This segmentation allows for adjustment and reconfiguration while keeping the overall assembly integrated during normal installation.

Inventive Principle:
Principle #1Segmentation

3Reliability

If fastening elements are permanently attached to the insulating element, then the risk of loss is eliminated, but the ability to replace or adjust fastening elements is reduced

Engineering Contradiction:
Improvecomponent retentionVSAvoidcomponent replaceability
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The fastening elements are pre-positioned and frictionally attached to the insulating element during manufacturing, ensuring they are in the correct location and orientation before installation. This preliminary attachment prevents loss during transport and installation while maintaining the ability to detach and replace them later if needed, as the frictional connection allows for controlled separation.

Inventive Principle:
Principle #10Preliminary action
