Solution Overview

Problem

Existing installation element mounting systems for heating circuit distributors are multi-part, leading to loose parts that can be lost during assembly, and the rigid fixation of bracket elements restricts pipe connection under restricted space conditions, with the distributor prone to being pulled out axially.

Innovation Solution

A C-shaped profiling in the receiving area of the wall bracket provides a form-fitting engagement in two spatial directions, preventing axial displacement and allowing rotation for accessible pipe connections, with a modular structure and latching elements ensuring secure and flexible installation without loose parts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a multi-part wall bracket structure is used, then the bracket elements can be rigidly fixed, but loose parts may be lost during assembly and the structure becomes complex

Engineering Contradiction:
Improverigid fixationVSAvoidmulti-part structure
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (base body, bracket element, adjustment wedge, clamping elements) into a single integrated wall bracket made of one piece. This merging eliminates the need for loose parts during assembly while maintaining the rigid fixation capability through the integrated design of all functional elements within the single piece structure.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single-piece wall bracket integrates multiple functions into one component: it provides mounting support, includes adjustable bracket elements for positioning, incorporates clamping mechanisms for secure fixation, and offers pipe connection capabilities. This multi-functionality eliminates the need for separate loose parts while achieving rigid fixation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Stability of the object's composition

If bracket elements are rigidly fixed in the wall bracket, then stable installation is achieved, but pipe connection is restricted under space constraints

Engineering Contradiction:
Improvestable installationVSAvoidpipe connection accessibility
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent incorporates an adjustment wedge that enables the bracket element to be positioned and fixed at different angles and positions. This dynamic adjustment capability allows the bracket element to be optimally oriented for pipe connection while maintaining stable installation, and the element can be adjusted even after initial mounting to accommodate spatial constraints.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If the wall bracket is designed as a single piece, then assembly is simplified and loose parts are eliminated, but manufacturing complexity may increase

Engineering Contradiction:
Improveassembly simplicityVSAvoidsingle-piece design
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent merges all functional components into a single molded piece, which simplifies assembly to a single insertion operation without requiring separate parts to be handled and assembled. While the single-piece design presents manufacturing challenges, the integration of all functions into one component eliminates complex assembly procedures.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If the receiving area has a C-shaped profile, then the installation element is secured in two spatial directions, but the structure becomes more complex

Engineering Contradiction:
Improveform-fitting engagementVSAvoidC-shaped profiling
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The C-shaped profile is integrated directly into the receiving area of the single-piece wall bracket, providing form-fitting engagement in two spatial directions. This integrated profiling secures the installation element reliably while being part of the overall simplified single-component design, balancing the increased structural detail with the reduction in assembly complexity.

Inventive Principle:
Principle #5Merging (Combining)
