Solution Overview

Problem

Existing holding elements for hydraulic units in vehicle brake systems are expensive and heavy due to their steel composition, which limits their cost-effectiveness and weight reduction potential while failing to adequately address noise and vibration issues during slip control operations.

Innovation Solution

A plastic-made holding element with integral stiffening ribs and a fastening strap design that includes metal reinforcement, optimized for rigidity, noise reduction, and vibration damping, allowing for a secure and lightweight connection to the carrier part without additional damping means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a holding element is made from steel to ensure strength and rigidity, then the mechanical strength and stability are improved, but the weight and production cost increase

Engineering Contradiction:
Improvemechanical strengthVSAvoidweight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The holding element is made from plastic material instead of steel, utilizing composite material principles to achieve weight reduction while maintaining structural integrity through integrated stiffening ribs that provide the necessary mechanical strength

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

Stiffening ribs are integrally formed at specific locations on the holding element to provide localized reinforcement, ensuring that strength is enhanced only where needed rather than requiring uniform thick-walled construction throughout the entire component

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If a holding element is made from steel to ensure rigidity, then the rigidity and permanent detection of electronic signals are improved, but the weight and production cost increase

Engineering Contradiction:

3Object-affected harmful factors

If additional damping means are added between the hydraulic unit and holding element to reduce noise and vibration, then the noise and vibration are reduced, but the device complexity and assembly costs increase

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The holding element itself is designed with integrated stiffening ribs that provide vibration damping and noise reduction functionality, eliminating the need for separate additional damping means and reducing overall device complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The stiffening ribs are integrally formed as part of the holding element structure, combining the structural support function with the vibration damping function into a single component rather than requiring separate damping elements

Inventive Principle:
Principle #5Merging (Combining)
