Solution Overview

Problem

Existing vehicle heaters face issues with stable attachment to support structures due to heavy loads, leading to vibrations and potential material stress or deformation, as the elastic cover element can cause relative movements and uneven compression of fastening bolts.

Innovation Solution

A mounting arrangement featuring a mounting base with support projections that extend beyond the base surface, allowing for a rigid and defined interaction with the support structure, eliminating relative movements and distributing load effectively, while the cover element provides a sealing function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an elastic cover element is used to seal the mounting base, then gas-tight sealing is achieved, but vibrations and relative movements occur under heavy loads

Engineering Contradiction:

Improvegas-tight sealingVSAvoidrelative movements

Core Design Contradiction:

ReliabilityVSStability of the object's composition

Solution Approach 1:

The mounting arrangement is divided into two independent functional components: the cover element (46) responsible for sealing and the support projections (76) responsible for mechanical stability. This segmentation allows each component to optimize its specific function without compromising the other, resolving the contradiction between sealing reliability and vibration stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support projections (76) act as intermediary elements between the mounting base (44) and the support structure (61). These projections provide rigid mechanical support and prevent relative movements, while the cover element (46) independently provides sealing. The support projections mediate the mechanical loads, preventing them from affecting the sealing function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If fastening bolts are used to attach the vehicle heater, then stable connection is achieved, but excessive stress and material deformation occur

Engineering Contradiction:

Improveconnection stabilityVSAvoidfastening bolt stress

Core Design Contradiction:

StrengthVSStress or pressure

Solution Approach 1:

The support function is extracted from the fastening bolts and transferred to dedicated support projections (76). The fastening bolts (64) are now solely responsible for securing the mounting base to the support structure, while the support projections handle the mechanical loads and prevent deformation. This extraction of the support function reduces stress on the fastening bolts.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The support projections (76) are pre-positioned on the mounting base (44) to engage with the support structure (61) before any heavy loads are applied. This preliminary positioning ensures that load-bearing structures are already in place to prevent deformation, allowing the fastening bolts to focus only on securing the assembly without bearing excessive stress.

3Reliability

If the cover element is compressed to ensure sealing, then gas-tight connection is achieved, but local compression variations cause deformation stress

Engineering Contradiction:

Improvesealing reliabilityVSAvoidcompression stress

Core Design Contradiction:

ReliabilityVSStress or pressure

Solution Approach 1:

The sealing function and the mechanical support function are segmented into separate components. The cover element (46) provides sealing through controlled compression, while the support projections (76) provide uniform mechanical support. This segmentation prevents local compression variations from causing deformation stress, as the support projections distribute loads independently of the sealing compression.

Inventive Principle:

Principle #1Segmentation
