Retaining Assembly for Braking Device Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing holding assemblies for fixing a flange part of a braking device to a motor vehicle bulkhead require significant effort and accessibility challenges, especially when installing and removing the device, as the bulkhead is poorly accessible from the vehicle interior, and the device needs to be supported to prevent tilting and falling.
Innovation Solution
A holding assembly featuring a form-fitting connection between the flange part and the retaining plate, utilizing a basin-shaped depression and asymmetrical design with a supporting edge and projections for precise alignment, along with an end fixing screw and retaining ring for secure fastening, allowing for easy installation and removal from the engine compartment side with minimal structural and functional effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If studs are inserted from the flange portion through the bulkhead into the passenger compartment and bolted from the passenger compartment, then the braking device can be fixed to the bulkhead, but the installation and removal effort is considerable due to poor accessibility of the bulkhead in the vehicle interior
Solution Approach 1:
The fastening operation is inverted by performing it from the engine compartment side instead of the passenger compartment side. The retaining plate with integrated fastening elements is installed from the engine compartment, allowing the braking device to be secured without requiring access to the difficult-to-reach passenger compartment area through the bulkhead.
Solution Approach 2:
The retaining plate merges multiple functions into a single component: it provides structural support for the braking device, creates a form-fitting connection through its basin-shaped depression, and integrates the fastening mechanism with the end fixing screw. This consolidation eliminates the need for separate support structures and simplifies the installation process.
2Stability of the object's composition
If the braking device is supported in the engine compartment to prevent tilting and falling out, then stability during installation is achieved, but additional support structures and complexity are required
Solution Approach 1:
The retaining plate combines the support function and fastening function into a single integrated structure. The basin-shaped depression provides both the support surface to prevent tilting and the form-fitting connection features for secure attachment, eliminating the need for separate support brackets or temporary fixtures.
Solution Approach 2:
The retaining plate is designed with distinct functional zones: the basin-shaped depression for support and alignment, the frame with groove for form-fitting connection, and the threaded hole for final fastening. This segmentation of functions within a single component achieves stability without adding external support structures.
3Productivity
If a form-fitting connection with basin-shaped depression and asymmetrical design is used, then precise alignment and quick installation are achieved, but manufacturing complexity increases
Solution Approach 1:
The retaining plate employs asymmetrical design elements including the basin-shaped depression with specific contour and the frame with groove positioned at particular locations. These asymmetrical features provide automatic alignment and precise positioning of the braking device during installation, ensuring correct orientation without requiring complex alignment procedures.
Solution Approach 2:
The form-fitting connection features (basin-shaped depression and frame with groove) are pre-formed during manufacturing of the retaining plate. This preliminary creation of alignment features ensures that during installation, the braking device automatically aligns and engages with the correct position, enabling quick installation without complex adjustment steps.
