Lower Control Arm Mount Braces for Off-Road Rock Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Factory-supplied mounting structures for vehicle steering knuckles are vulnerable to damage from rocks and other objects during off-road driving, leading to steering malfunctions and alignment issues.
Innovation Solution
Reinforcing braces with sturdy metal flanges and base plates are attached to the factory-supplied chassis mounts, providing reinforcement and a deflecting shield to protect the mounting structures from impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If factory-supplied mounting structures are used for lower control arms, then the vehicle can be assembled with standard components, but the mounting structures are vulnerable to damage from rocks and objects during off-road driving
Solution Approach 1:
The patent applies preliminary action by providing reinforcement braces that are pre-installed on the steering knuckle before the lower control arm is attached. These braces protrude through openings in the control arm mounting structures, creating a protective barrier in advance that deflects rocks and objects away from the vulnerable factory mounting structures before impact occurs.
Solution Approach 2:
The reinforcement braces serve as an intermediary element between the external environment (rocks, objects) and the factory-supplied mounting structures. The braces absorb and deflect the impact forces, preventing direct contact with the vulnerable mounting structures while allowing the standard factory components to remain in place.
2Strength
If heavy-duty steering knuckles and control arms are installed for rock crawling, then resistance to rock damage is improved, but the factory mounts for attaching the lower control arm to the chassis remain vulnerable
Solution Approach 1:
The patent applies local quality by providing reinforcement specifically at the vulnerable mounting structure locations where the lower control arm attaches to the chassis. The braces are positioned to protrude through openings at these critical points, providing localized protection without requiring replacement of the entire steering knuckle or control arm assembly with heavy-duty components.
3Reliability
If reinforcement braces are added to protect mounting structures, then resistance to rock damage is improved, but the device complexity increases
Solution Approach 1:
The patent merges the reinforcement function with the existing steering knuckle structure by integrating the braces as part of the knuckle assembly. The braces utilize the existing openings in the lower control arm mounting structures, combining protective functionality with the original design rather than adding completely separate components.
Solution Approach 2:
The reinforcement braces serve multiple functions: they strengthen the mounting structures against rock damage, maintain alignment during impact, and work with both factory and after-market control arms. This multi-functionality reduces the need for additional specialized components.

AI summary
The present invention provides reinforcing braces that may be attached to the factory-supplied chassis mounts for the lower control arms of the steering knuckles of vehicles to reinforce and shield the mounts from objects below the vehicle that may be encountered when traveling through rugged terrain. The braces of the present invention are designed for the front and rear control arm mounts, each brace including a pair of parallel sturdy metal flanges that are generally perpendicularly attached to a sturdy metal lower base plate. Each flange is designed to be attached to one of the flanges of the factory-supplied chassis mounts, and has an opening therein for receiving mounting hardware and strengthening of the camber adjustment structures. The sturdy metal lower base plates may extend out and away from the flanges of the brackets to provide a lower shield to protect the chassis and mounting hardware from damage that may occur from contact with large objects that may be encountered below the vehicle. The front base plate may include an elongated section that extends toward the front of the vehicle to provide a shield for deflecting large objects as the vehicle moves forward.
