Removable Brush Guard Mounting With Pivot Pins and Locking Pins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush guards for vehicles, particularly trucks, are difficult to mount and dismount due to the numerous fasteners and associated corrosion, requiring significant effort and time.
Innovation Solution
A quick-release brush guard system featuring a brush guard shield and floor assembly with pivot pins and lock assemblies that secure to a vehicle's frame, allowing for rapid installation and removal without the need for fastener removal, and optionally incorporating a winch for front vehicle use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If brush guards are bolted to the frame of the vehicle with multiple fasteners, then the brush guard is stable and strong, but it requires significant effort and time to mount and dismount due to the multitude of fasteners and associated corrosion
Solution Approach 1:
The brush guard system is divided into modular components including the brush guard assembly, floor assembly, and quick-release mechanism with separate lock assemblies. This segmentation allows the brush guard to be quickly detached by releasing individual lock assemblies rather than removing multiple fasteners, resolving the contradiction between stability and quick installation/removal.
Solution Approach 2:
The system employs a dynamic quick-release mechanism with retractable lock pins that can be quickly engaged and disengaged. The lock assemblies allow the brush guard to transition between locked (stable) and unlocked (removable) states, enabling both strong attachment and rapid removal without corrosion issues associated with traditional fasteners.
2Strength
If brush guards use multiple fasteners to secure to the vehicle frame, then the connection is strong and stable, but the mounting and dismounting process requires significant effort
Solution Approach 1:
The traditional multiple fastener system is replaced by extracting the essential function of secure attachment into a simplified quick-release mechanism. The lock assemblies with retractable pins provide the necessary connection strength while eliminating the need for multiple bolts, significantly reducing the effort required for mounting and dismounting.
Solution Approach 2:
The quick-release mechanism acts as an intermediary between the brush guard and vehicle frame, providing strong connection when engaged but allowing easy separation when unlocked. This intermediary system mediates between the conflicting requirements of strong attachment and ease of operation.
3Productivity
If the brush guard uses a quick-release format without fasteners, then it can be quickly mounted and dismounted, but it may compromise the stability and strength of the connection
Solution Approach 1:
The lock assemblies are pre-positioned and designed to automatically engage with the vehicle frame when the brush guard is installed. The retractable lock pins are prepared in advance to secure the connection, ensuring both quick installation and reliable stability without compromising either requirement.

AI summary
A brush guard system for mounting on the front of a vehicle. The brush guard system includes a removable brush guard construct having a brush guard shield roughly the size of the front of a vehicle. The brush guard shield is mounted to a floor assembly. The floor assembly comprises a left pivot assembly spaced from a right pivot assembly that releasably engages a hooking bar that is secured to the frame of the vehicle. The hooking bar utilizes a pair of spaced hook plates to receive and support the brush guard construct. Pivot pins are utilized to pivotably mount the brush guard construct to the hooking bar and retractable locking pins are utilized to lock the brush guard construct to the hooking bar.
