Off-Road Vehicle Flexible Mudguard Radiator Air Block
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional off-road vehicles do not effectively suppress hot radiator air from entering the passenger compartment during the assembly process, and fail to prevent water, mud, and debris from splashing into critical areas.
Innovation Solution
The design incorporates a front-side housing with a separate, flexible mudguard made of elastic material, positioned between the front fender portions and the instrument panel, which extends to the radiator and is supported by the instrument panel and front-floor cover, blocking exhaust air and debris from entering the passenger compartment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate mudguard component is used to block radiator exhaust air and debris, then protection against harmful factors is improved, but device complexity increases
Solution Approach 1:
A separate mudguard component acts as an intermediary element positioned between the radiator and instrument panel. This intermediate structure blocks the direct path of hot exhaust air and debris toward the passenger compartment while maintaining functional separation from both the radiator housing and instrument panel assemblies.
Solution Approach 2:
The vehicle body is divided into distinct functional segments: the front-side housing containing the radiator, the instrument panel assembly, and the separate mudguard component. This segmentation allows each part to be independently manufactured, assembled, and maintained, with the mudguard specifically dedicated to blocking harmful factors.
2Manufacturing precision
If the front-side housing is integrally formed with the fender portions, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The front-side housing is separated from the fender portions, allowing each component to be manufactured independently using optimized processes. The fender portions can be formed separately from the housing, enabling independent production and assembly rather than requiring complex integral forming operations.
Solution Approach 2:
The fender portions and front-side housing are prepared as separate pre-assembled units before final assembly. This preliminary preparation allows for easier manufacturing of each component and simplifies the overall assembly process, as the units can be attached in a straightforward sequence rather than requiring complex integral forming.

AI summary
An off-road vehicle is provided with a front-side housing that has a rear end that defines a gap with an upper end of a front-floor cover that is spanned by a flexible member that is a separate component from the front-side housing and the front-floor cover.
