Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle protection systems and brake assembly backing plates are not effectively secured to vehicle axles, leading to potential detachment and instability.
Innovation Solution
A mechanism using studs with expanded sections and knurls for a press fit within axle flange bolt holes, along with spacers to secure vehicle protection systems and backing plates to the axle flange, ensuring a stable connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bolts and nuts are used to secure the backing plate to the axle flange, then the assembly process is simple, but the connection stability and reliability are insufficient leading to potential detachment
Solution Approach 1:
The stud is divided into multiple functional segments: an expanded section for insertion into the bolt hole, knurls for forming a press fit, a threaded section for securing, and a spacer section for positioning. This segmentation allows each part to perform its specific function optimally, achieving reliable connection through structured division of the securing mechanism.
Solution Approach 2:
The expanded section of the stud is pre-formed to fit into the bolt hole before the actual securing operation. The knurls are pre-configured to form a press fit when the stud is inserted, creating a stable connection foundation before the final tightening operation occurs.
2Reliability
If the stud design includes expanded sections and knurls for press fit, then the attachment reliability improves, but the manufacturing complexity increases
Solution Approach 1:
The stud geometry is designed with specific parameter variations including an expanded section with increased diameter, knurls with specific pitch and depth, and threaded sections with defined thread pitch. These parameter changes are optimized to achieve the desired press fit and securing characteristics while maintaining manufacturability through standard forming processes.
3Stability of the object's composition
If multiple studs with spacers are used to secure both the protection system and backing plate, then the overall stability improves, but the number of components and assembly steps increases
Solution Approach 1:
The stud design merges multiple functions into a single component: the expanded section provides insertion and positioning, the knurls create the press fit connection, the threaded section enables securing with a nut, and the spacer maintains proper spacing. This merging reduces the need for separate positioning features, insertion guides, and spacing elements that would otherwise be required.
Solution Approach 2:
The multi-functional stud serves as an insertion tool, positioning element, connection fastener, and spacing component all in one. This universal design allows the same component to perform multiple roles in the assembly process, reducing the total number of different component types needed while maintaining system stability.

AI summary
A mechanism for securing a vehicle protection system to an axle of a vehicle is provided. The mechanism may include a plurality of studs that are configured to secure the vehicle protection system and the backing plate of a brake assembly to an axle flange of a vehicle's axle. Each stud may include an outer end separated from an inner end by a spacer. The outer end may also include an expanded section adjacent the spacer that can be positioned within bolt holes of the axle flange. The expanded section may include knurls for forming a press fit within the bolt holes.
