Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing holding assemblies for fixing a flange part of a braking device to a motor vehicle bulkhead are costly and time-consuming to install and remove due to poor accessibility, requiring support within the vehicle interior to prevent tilting and falling.

Innovation Solution

A holding assembly with a holding plate fastened to the engine compartment side of the bulkhead, featuring positive and non-positive connections, allows for simple and rapid mounting and dismantling of the braking device from the engine compartment side, using screws and a plastically deformed frame with hooks and internal threads for secure engagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If studs are inserted through the bulkhead into the vehicle interior and screwed from the vehicle interior, then the braking device can be fastened to the bulkhead, but the installation and removal cost is considerable due to poor accessibility

Engineering Contradiction:

Improvefastening reliabilityVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent inverts the fastening direction by providing threaded bores in the holding plate (engine compartment side) instead of requiring studs to be screwed from the vehicle interior. This allows screws to be inserted from the engine compartment side, making installation and removal accessible from the engine compartment without requiring access to the vehicle interior.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

Engineering Contradiction:

Improvefastening reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

3Reliability

If the braking device is fastened using studs from the vehicle interior, then secure fastening is achieved, but the braking device must be simultaneously supported in the engine compartment to prevent tilting and falling out

Engineering Contradiction:

Improvefastening securityVSAvoidsupport requirement

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The holding plate is first fastened to the bulkhead using holding screws from the engine compartment side, creating a stable base before the braking device is attached. This preliminary action eliminates the need for temporary support during the fastening process.

Inventive Principle:

Principle #10Preliminary action

4Productivity

If a holding plate with positive connection elements is used, then rapid mounting is enabled, but the structural complexity increases

Engineering Contradiction:

Improvemounting speedVSAvoidconnection structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The connection system is segmented into two independent parts: positive connection elements (hooks) for rapid engagement and threaded bores for secure fastening. This segmentation allows the mounting process to be divided into a quick positioning phase followed by a secure fastening phase, maintaining simplicity while enabling rapid mounting.

Inventive Principle:

Principle #1Segmentation
