Utility Vehicle Frame Cover Water Drainage Guide
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water entering through openings in the frame cover of a utility vehicle can flow into the riding space, compromising the interior environment.
Innovation Solution
A utility vehicle design featuring a frame cover with inclined guide surfaces that direct water entering through openings into a discharge port, preventing it from reaching the riding space by guiding it outside the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If openings are provided in the frame cover to accommodate the vehicle body frame, then the vehicle body frame can pass through the frame cover, but water can enter the frame accommodating space and flow into the riding space
Solution Approach 1:
A water discharge port is introduced as an intermediary element between the opening and the riding space. The discharge port receives water that enters through the opening and directs it to the exterior, preventing water from reaching the riding space while maintaining the structural function of the opening for the vehicle body frame
Solution Approach 2:
The solution adds a vertical dimension to water management by positioning the discharge port at a lower location than the opening. This creates a gravitational drainage path that redirects water flow from the horizontal plane (where it would enter the riding space) to a downward trajectory, discharging water to the exterior below the frame accommodating space
2Stability of the object's composition
If the frame cover is designed with openings for frame portions, then the frame structure can be integrated, but water flowing externally can enter through clearances and reach the riding space
Solution Approach 1:
The harmful function of the opening (allowing water entry) is separated from its useful function (accommodating the frame). The discharge port extracts and removes the water that enters through the opening, preventing it from reaching the riding space while the opening maintains its structural purpose
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents water from entering the riding space, maintaining a dry and comfortable interior environment even in wet conditions.
Implementation Method 1
a guide is provided in the frame accommodating space, and includes a guide surface inclined in a downward direction toward the discharge port, the guide being configured to guide to the discharge port, water which flows into the frame accommodating space through the at least one opening

AI summary
A utility vehicle comprises a vehicle body frame including: side frame sections, a cabin frame section, and a cross frame section; and a frame cover including a dash cover section disposed forward of seats, and a tire upper cover section disposed forward of the dash cover section and above a front wheel, the frame cover defining a frame accommodating space. The frame cover is provided with an opening through which the frame accommodating space and an outside region are in communication with each other, the vehicle body frame being configured to pass through the opening. A discharge port is disposed below the opening to discharge water to an outside region. A guide is provided in the frame accommodating space, and includes a guide surface inclined in a downward direction toward the discharge port, to guide the water in the frame accommodating space to the discharge port.
