Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Factory-supplied chassis mounts for the lower control arms of vehicle steering knuckles are not sturdy enough to withstand significant forces and impacts from rocks, boulders, and other objects encountered during off-road driving, leading to potential damage and steering malfunctions.
Innovation Solution
The development of reinforcing braces that can be attached to the factory-supplied chassis mounts, featuring sturdy metal flanges and a lower base plate with optional extensions, providing additional strength and protection against impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If factory-supplied chassis mounts are used for lower control arms, then the vehicle can be assembled with standard components, but the mounting structures are not sturdy enough to withstand significant forces and impacts from rocks and obstacles during off-road driving
Solution Approach 1:
The reinforcing brace is designed as a separate component that can be attached to the existing factory-supplied chassis mount. This segmentation allows the strengthening function to be added without replacing the entire mounting structure, thereby increasing strength while minimizing the increase in overall device complexity.
Solution Approach 2:
The solution combines the factory-supplied mount with an additional reinforcing brace made of sturdy metal material. This creates a composite mounting structure where the brace and original mount work together to provide enhanced strength and impact resistance while maintaining the original mount's basic function.
2Reliability
If the lower control arm mounting structures are made sturdier to withstand off-road forces, then protection against damage improves, but the weight of the mounting structure increases
Solution Approach 1:
By segmenting the strengthening function into a separate attachable brace rather than replacing the entire mount with a heavier custom-designed structure, the solution provides the necessary reliability improvement while minimizing unnecessary weight addition. Only the specific protective function is added separately.
3Object-affected harmful factors
If reinforcing braces are added to factory-supplied chassis mounts, then protection against impacts from rocks and obstacles improves, but the device complexity increases
Solution Approach 1:
The protective function is segmented into a separate reinforcing brace component that attaches to the existing mount. This allows impact protection to be added without redesigning the entire mounting structure, thereby reducing the complexity increase compared to a complete custom mount design.
Solution Approach 2:
The reinforcing brace acts as an intermediary protective element between the external impact forces (rocks, obstacles) and the vulnerable factory-supplied chassis mount. This intermediary structure absorbs and deflects impacts, protecting the original mount while adding minimal complexity.
4Adaptability or versatility
If camber plates with oval-shaped openings are used to allow camber adjustments, then alignment adjustability improves, but the tabs cannot prevent hardware from moving during significant forces, causing tabs to bend or deform
Solution Approach 1:
The reinforcing brace merges the camber adjustment functionality with enhanced structural support. By providing additional reinforcement at the tab locations while maintaining the oval opening configuration, the design allows camber adjustment capability to be preserved while significantly strengthening the tabs to prevent bending or deformation under load.
Solution Approach 2:
The solution creates a composite structure where the reinforcing brace works together with the existing camber plate and tabs. This composite arrangement provides both the necessary adjustability through the oval openings and the additional strength to prevent tab deformation during off-road driving.

AI summary
The present invention provides reinforcing braces for attachment to factory-supplied chassis mounts for the lower control arms of steering knuckles of vehicles to reinforce and shield the mounts from objects below the vehicle encountered when traveling through rugged terrain. Each brace includes at least one sturdy metal flange that is 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 an open section for engagement with camber adjustment structures. The sturdy base plates provide a lower shield to protect the chassis and mounting hardware from damage from contact with large objects encountered below the vehicle. The front base plate may also include an elongated front shield for deflecting large objects as the vehicle moves forward.
