Solution Overview

Problem

Existing assemblies for vehicle braking systems, particularly utility vehicles, experience an insufficient holding effect due to all-around edge clamping geometry, leading to material separation between the assembly and internal components.

Innovation Solution

Incorporating a rivet-shaped second clamping element with a shaft and head part, formed in a single injection molding step, to enhance the holding effect by creating an opposing surface for internal components, thereby increasing adhesion reactionary forces and eliminating the need for external fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If all-around edge clamping geometry is used, then the assembly structure is simple, but the holding effect is insufficient leading to material separation

Engineering Contradiction:
Improveassembly structureVSAvoidholding effect
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The clamping function is segmented into two distinct elements: a first clamping feature for edge clamping and a rivet-shaped second clamping element for punctual clamping. This segmentation allows each element to perform its specific clamping function optimally, preventing material separation while maintaining structural simplicity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rivet-shaped second clamping element provides localized punctual clamping at specific positions, complementing the distributed edge clamping of the first clamping feature. This local quality enhancement addresses the insufficiency of edge clamping alone by adding focused clamping force where needed.

Inventive Principle:
Principle #3Local quality

2Reliability

If additional clamping elements are added to improve holding effect, then the fixation is improved, but the device complexity increases

Engineering Contradiction:
ImprovefixationVSAvoidassembly structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The first clamping feature and rivet-shaped second clamping element are integrated into a single assembly structure, forming a unified clamping system. This merging approach improves fixation through multiple clamping mechanisms while avoiding the complexity of separate, independently assembled components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The assembly structure serves multiple functions: the base element provides structural support, the first clamping feature provides edge clamping, and the rivet-shaped second clamping element provides punctual clamping. This multi-functionality achieves superior fixation without proportionally increasing device complexity.

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