Unpowered Swing Arm for Vehicle Tire Debris Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tire protection technologies for vehicles, particularly in agricultural settings, are often complex, costly, and inefficient due to the need for power-assisted mechanisms and mechanical complexity, which can hinder their effectiveness in displacing ground debris like stubble without requiring frequent positional adjustments for different terrains.
Innovation Solution
A swing arm-based system that utilizes an unpowered ground debris displacement mechanism, with a swing arm mounted to a vehicle's structural element, allowing for the displacement of debris without the need for hydraulics or electronics, and can maintain a single position to accommodate various terrains, thereby protecting tires from damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional barrier technologies are used to block ground debris, then tire protection is improved, but device complexity and cost increase due to power-assisted mechanisms
Solution Approach 1:
The swing arm displacement device is designed to be self-service by utilizing the vehicle's forward motion and the natural swing arm mechanics to displace ground debris. The device automatically returns to its blocking position through the swing arm's natural oscillation, eliminating the need for power-assisted raising and lowering mechanisms while maintaining continuous tire protection.
Solution Approach 2:
The swing arm device introduces dynamic motion to the previously static barrier concept. By allowing the displacement member to swing freely and return to its blocking position, the system adapts to varying terrain conditions without requiring complex control systems, thus improving reliability while keeping device complexity low.
2Reliability
If conventional barrier technologies are used to block ground debris, then tire protection is improved, but adaptability to rough terrain decreases due to fixed positioning requirements
Solution Approach 1:
The swing arm displacement device allows the displacement member to dynamically adjust its position through swinging motion when encountering rough terrain, while automatically returning to the blocking position. This dynamic behavior enables the system to adapt to varying terrain conditions without sacrificing tire protection capability.
3Reliability
If conventional mechanical systems with multiple components are used, then tire protection is improved, but ease of operation and maintenance worsen
Solution Approach 1:
The invention extracts and eliminates complex mechanical components such as springs, rollers, chains, and drag bars from the tire protection system. By using a simple swing arm mechanism mounted to the vehicle frame, the device achieves effective ground debris displacement while dramatically improving ease of operation and maintenance.
Solution Approach 2:
The swing arm displacement device serves multiple functions with a single simple structure: it blocks ground debris, displaces stubble through swinging motion, and automatically returns to position without requiring separate mechanisms for each function, thereby improving ease of operation.

AI summary
Methods and apparatus may allow for the protection of vehicle tires from ground debris. A swing arm configuration may be used to displace ground debris from the path of a vehicle tire. The length of the swing arm may be established to maximize the vehicle's angle of approach. The motion of the swing arm may be arrested with a swing motion arrest substantially collocated with a swing axis pivot point. A ground debris displacement system may be capable of unpowered operation from a single position on a vehicle.
