Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake assemblies require complex disassembly and reassembly procedures to adapt to different numbers of stator and rotor plates, making it difficult to accommodate vehicles of varying sizes and masses.
Innovation Solution
A brake assembly with a stop member that can be axially positioned at multiple points, allowing for easy adaptation to brake packs of different sizes, featuring radially extending protrusions and axially spaced coupling features, such as annular grooves or threaded portions, for secure coupling to the stationary portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the brake assembly uses a fixed stop member position, then the structural simplicity is maintained, but the adaptability to different brake pack sizes is reduced
Solution Approach 1:
The stop member is segmented with multiple coupling features at different axial positions, allowing it to be positioned at various locations along the stationary portion. This segmentation enables the same stop member to adapt to different brake pack configurations without requiring multiple different components.
Solution Approach 2:
The stop member is designed with multi-functionality by incorporating multiple coupling features that can engage with the stationary portion at different axial positions. This universal design allows a single stop member to serve multiple positioning functions, accommodating brake packs of varying sizes and configurations.
2Ease of manufacture
If the brake assembly allows easy reconfiguration for different brake pack sizes, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The coupling features are segmented into multiple discrete engagement points along the axial direction. This segmentation allows for simple reconfiguration by selecting different coupling features based on the brake pack size, making the reconfiguration process straightforward while maintaining a relatively simple overall structure.
Solution Approach 2:
The stop member is designed with dynamic positioning capability, allowing it to be axially adjusted to different positions. This dynamic feature enables easy reconfiguration for different brake pack sizes while the coupling mechanism maintains a relatively simple structure through standardized engagement features.
3Adaptability or versatility
If multiple coupling features are provided on the stop member, then the adaptability to different axial positions is improved, but the manufacturing complexity increases
Solution Approach 1:
The multiple coupling features are segmented along the axial direction at predetermined positions. This segmentation allows for standardized manufacturing of each coupling feature, reducing the overall manufacturing complexity while ensuring precise positioning through consistent spacing and standardized feature geometry.

AI summary
The present disclosure relates to a brake assembly comprising a stationary portion forming a hollow for receiving a brake pack therein, and a stop member partially received in or configured to be partially received in the hollow along an axis to form a brake pack stop, wherein the stop member has a plurality of axially spaced coupling features for selectively coupling the stop member to the stationary portion at either one of two or more different axial positions of the stop member relative to the stationary portion.
