Utility Vehicle Front Sealing via Cabin Wall and Inner Fender Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing front structure of utility vehicles allows dust and water to enter the cabin and front chamber through gaps between the front fenders and inner fender, making it difficult to keep these areas clean.
Innovation Solution
A utility vehicle design where the cabin front wall and inner fender are connected throughout the vehicle width, forming a sealed front wheel space that prevents dust and water from entering, with optional features like a connecting member for improved rigidity, a heat insulation guard to reduce heat transfer, and a storage box for cargo in the front chamber.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the front fenders and inner fender are disposed to block dust, then dust protection is improved, but gaps between components allow dust and water to enter the cabin
Solution Approach 1:
The patent merges the functions of the front fenders and inner fender by connecting them through the cabin front wall to form an integrated sealed structure. This combination eliminates the gaps that existed between separate components, preventing dust and water from entering the cabin while maintaining effective dust blocking capability.
Solution Approach 2:
The cabin front wall acts as an intermediary component that connects the front fenders and inner fender. This intermediate structure bridges the gap between the dust-blocking components and the cabin, creating a sealed barrier that prevents harmful factors from reaching the interior space.
2Reliability
If the cabin front wall and inner fender are connected throughout the vehicle width, then sealing effectiveness is improved, but structural rigidity may be compromised
Solution Approach 1:
The sealing structure is segmented into distinct components (front fenders, cabin front wall, inner fender) that are connected at specific locations. This segmentation allows each component to maintain its structural integrity while forming a continuous sealed barrier when assembled, preventing rigidity loss despite the extended connection.
3Strength
If a connecting member is added to improve rigidity, then structural strength is improved, but device complexity increases
Solution Approach 1:
The cabin front wall serves multiple functions: it acts as a structural component providing rigidity, a sealing element preventing dust and water entry, and a connecting member joining the front fenders and inner fender. This multi-functionality eliminates the need for separate connecting members, maintaining structural strength without increasing device complexity.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively seals the cabin and front chamber from dust and water, enhances rigidity and heat insulation, and provides additional storage capacity, keeping the interior clean and functional.
Implementation Method 1
a heat insulation guard provided between the radiator and the cabin front wall and configured to block heat transferred from the radiator to the cabin front wall

AI summary
A utility vehicle according to the invention includes a body frame supporting a cabin disposed between a pair of left and right front wheels and a pair of left and right rear wheels, a cabin front wall extending substantially throughout a vehicle width at a front end of the cabin, and an inner fender covering a lower surface of a front chamber located ahead of the cabin and above the front wheels and extending substantially throughout the vehicle width. The cabin front wall and the inner fender are connected to each other substantially throughout the vehicle width and form a front wheel space including wheel housings of the front wheels and a space between the front wheels.
