Brake Device Retaining Assembly for Simplified Bulkhead Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing retaining subassembly for fixing a flange portion of a brake device to a motor vehicle bulkhead is complex and difficult to assemble due to poor accessibility, requiring screws to be inserted from the vehicle's inner space, which complicates the fitting and removal process.
Innovation Solution
A retaining subassembly with a retention plate and flange portion connected via a positive-locking mechanism, utilizing a basin-like recess and asymmetrical design for easy orientation and securing, along with a non-positive-locking final fixing screw for rapid assembly, allowing for simple and efficient attachment from the engine compartment side.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are inserted from the vehicle's inner space to fix the brake device, then the brake device can be secured to the bulkhead, but the assembly complexity increases and accessibility is reduced
Solution Approach 1:
The patent inverts the traditional assembly direction by enabling screws to be inserted from the engine compartment side rather than from the vehicle's inner space. The retention plate is designed with a recess that allows the screw to be inserted from the accessible engine compartment side, reversing the conventional approach and eliminating the need to access the difficult-to-reach inner space for assembly operations.
2Reliability
If stay bolts are introduced through the bulkhead into the vehicle inner space, then the brake device can be fixed, but the fitting and removal process becomes time-consuming
Solution Approach 1:
The retention plate is pre-formed with a basin-like recess that guides and positions the stay bolt during assembly. This preliminary structural preparation ensures that the bolt automatically orients itself correctly as it is inserted from the engine compartment side, eliminating the need for complex alignment operations and reducing assembly time significantly.
3Stability of the object's composition
If the brake device is supported in the engine compartment during assembly, then tilting and falling out is prevented, but the overall assembly process becomes more complex
Solution Approach 1:
The retention plate features an asymmetrical basin-like recess with specific geometric contours that provide inherent mechanical guidance and positioning for the stay bolt. The asymmetrical shape creates natural stopping points and orientation references, ensuring the bolt cannot be inserted at incorrect angles, thereby providing stability and preventing tilting without requiring additional support structures or complex procedures.

AI summary
A retaining assembly for fixing a flange part, which is provided on a braking device, to a firewall of a motor vehicle, the firewall separating an engine chamber from a vehicle interior. A retaining plate is secured to the firewall face facing the engine chamber, and the flange part and the retaining plate are engaged with each other by both a form-fitting as well as force-fitting connection.
