Solution Overview

Problem

Existing brake carriers for disc brakes face challenges in optimizing installation space and weight due to geometric constraints and strength requirements, particularly when accommodating components like brake cylinders, leading to space conflicts and inefficient material usage.

Innovation Solution

The brake carrier is designed with contact surfaces rotated by an angle relative to a horizontal plane, with the brake carrier itself serving as the variant-driving component, allowing for angular offset without altering the axle body geometry, and incorporating geometric elements like thickened webs, toroidal contours, and reinforcing ribs to reduce mechanical stresses and save material.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the brake carrier is designed with traditional axial or parallel mounting to the vehicle axle, then the installation space for the brake caliper is occupied, but the guide elements cannot be spaced further apart resulting in less stable and higher-friction guidance

Engineering Contradiction:
Improvestability of brake caliper guidanceVSAvoidinstallation space for brake caliper
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The patent applies dimensionality change by rotating the mounting plane of the brake carrier from an axial/parallel orientation to a radial orientation relative to the vehicle wheel axle. This angular repositioning in a different dimensional orientation creates new installation space for the brake caliper while allowing guide elements to be spaced further apart, thereby improving guidance stability and reducing friction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Weight of moving object

If the brake carrier is made lighter to reduce weight, then material usage is reduced, but the strength requirements for the brake carrier may not be met

Engineering Contradiction:
Improveweight of brake carrierVSAvoidstrength of brake carrier
Core Design Contradiction:
Weight of moving objectVSStrength

Solution Approach 1:

The patent applies local quality by implementing geometric elements such as thickened webs, torus-shaped contour features, and bracket-like thickenings with reinforcing ribs at specific locations where mechanical stresses occur. These localized reinforcements maintain the necessary strength and stress distribution in critical areas while allowing the overall brake carrier to use less material and reduce weight.

Inventive Principle:
Principle #3Local quality

3Area of stationary object

If the contact surfaces of the brake carrier are positioned in a horizontal plane, then the brake carrier geometry is simple, but the installation space for adjacent components is limited and brake cylinder space conflicts arise

Engineering Contradiction:
Improveinstallation space for adjacent componentsVSAvoidcomplexity of brake carrier geometry
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent applies asymmetry by rotating the contact surfaces of the brake carrier from a horizontal plane to a radial plane at a defined angle relative to the vehicle axle. This asymmetric angular positioning creates additional installation space for adjacent components such as the brake cylinder, eliminating space conflicts while the overall structural symmetry is maintained through corresponding features on opposite sides.

Inventive Principle:
Principle #4Asymmetry

4Area of stationary object

If the axle body is modified to create installation space for brake cylinder, then the installation space problem is solved, but the axle body is subject to geometrically disadvantageous modifications increasing cost

Engineering Contradiction:
Improveinstallation space for brake cylinderVSAvoidmanufacturing cost of axle body
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The patent applies the extraction principle by removing the need for axle body modifications and instead creating the required installation space through the brake carrier's own angular geometry. The radial mounting plane of the brake carrier inherently provides the necessary space for the brake cylinder and other adjacent components, eliminating costly geometric modifications to the axle body while maintaining all functional requirements.

Inventive Principle:
Principle #2Taking out (Extraction)
