Skid Plate Drain Opening With Liquid Spread Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multipurpose vehicles face issues with engine oil or radiator cooling water spreading over a wide area of the skid plate, necessitating cumbersome cleaning and potentially compromising the skid plate's protective capability and strength due to larger openings.
Innovation Solution
A multipurpose vehicle design featuring a skid plate with a spread prevention section surrounding the drain outlet opening, which prevents liquid substances from spreading and includes reinforcing ribs to maintain strength and facilitate easy cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a larger opening is provided in the skid plate to prevent engine oil from sticking around the opening, then engine oil can pass through more easily, but the protective capability against flying stones deteriorates and the strength of the skid plate decreases
Solution Approach 1:
The opening is divided into an inner peripheral area and an outer peripheral area, with the spread prevention section separating these regions. This segmentation allows the opening to be optimized for oil discharge while maintaining protective coverage for stone impact resistance.
Solution Approach 2:
The spread prevention section is strategically positioned at the outer peripheral area of the opening to specifically address oil spreading in that region, while the inner peripheral area maintains its opening function for oil discharge. This localized approach preserves overall protective capability while solving the specific oil sticking problem.

3Ease of operation
If the skid plate is removed for cleaning to remove engine oil spreading over a wide area, then thorough cleaning can be achieved, but the complexity and time required for maintenance increases
Solution Approach 1:
The spread prevention section is designed to actively prevent oil from spreading beyond the outer peripheral area of the opening, causing oil to accumulate in a confined region. This self-containing feature eliminates the need for complete skid plate removal during cleaning, as oil can be easily wiped away from the limited accumulation area while the plate remains installed.
