Cabin Mount Structure for Dirt-Resistant Off-Road Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles designed for off-road use face issues with dirt ingress causing soiling and noise due to gaps in cabin mountings, which can impair suspension travel and increase the risk of detachment during accidents, necessitating improved protection and secure attachment of the cab.
Innovation Solution
A cabin mounting system with a chassis bracket and cabin bracket featuring a molded element to prevent dirt accumulation, combined with a hydraulic actuator for active control and a position sensor to manage relative movement, ensuring secure attachment and reduced maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lower bearing plate is welded or bolted to the chassis plate creating a 90-degree angle transition, then secure attachment is achieved, but dirt accumulation occurs in the angle between plates
Solution Approach 1:
The patent applies the 'Blessing in disguise' principle by using the molded element to convert the harmful angle between plates into a beneficial feature. The molded element is specifically designed to fit into and cover the 90-degree angle between the lower bearing plate and chassis plate, transforming what was previously a dirt-trapping hazard into a smooth, dirt-resistant surface that maintains the secure welded or bolted attachment.
2Adaptability or versatility
If gaps exist between moving components of the cab mounting, then mobility is enabled, but noise increases due to dirt particles filling gaps
Solution Approach 1:
The molded element acts as an intermediary component between the lower bearing plate and the chassis plate. It fills the gap area while allowing the upper and lower bearing plates to maintain their relative mobility. The molded element's flexible or deformable nature enables it to accommodate movement while preventing dirt ingress, thus reducing noise without compromising cabin mobility.
3Ease of manufacture
If the molded element is made of plastic, then flexibility and ease of attachment are improved, but durability is reduced compared to metal
Solution Approach 1:
The patent applies 'Parameter changes' by offering different material parameters for the molded element - plastic or metal - depending on the specific application requirements. The plastic version provides ease of attachment through gluing, screwing, wedging, clamping, or plastic welding, while the metal version provides increased durability through welding. This parameter change allows optimization based on whether ease of manufacture or component lifespan is the priority.
