ATV Lower Protector Fastening via Recessed Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing all terrain vehicle protectors for the lower rear end are prone to being dislodged during collisions with the road surface, failing to effectively secure the vehicle's lower portion.
Innovation Solution
An all terrain vehicle design featuring a protector main body and a fixing plate with strategically positioned insertion holes and a recessed portion to securely fasten the protector to the vehicle body, utilizing a synthetic resin for the protector and aluminum alloy for the fixing plate, which reduces the risk of damage and dislodgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protector is disposed at the lower rear end of the rear arm to protect the lower portion of the vehicle body, then the lower portion is protected, but the protector can be wrested off when it collides with the road surface
Solution Approach 1:
The fastening structure is divided into multiple insertion holes (first insertion holes in the fixing plate and second insertion holes in the recessed portion) distributed at different positions. This segmentation allows the protector to be secured at multiple points, distributing the collision forces across several fastening locations rather than concentrating stress at a single point, thereby preventing the protector from being wrested off during road surface collisions.
Solution Approach 2:
The invention transitions from a single-plane fastening approach to a multi-dimensional fastening system. The fixing plate is disposed in the recessed portion with insertion holes arranged in different spatial positions (including width direction and depth direction). This multi-dimensional arrangement creates a more robust fastening structure that resists collision forces from various directions, preventing the protector from being dislodged during operation.
2Reliability
If multiple fastening points are used to secure the protector, then the protector is more securely attached, but the structure becomes more complex
Solution Approach 1:
The fixing plate and the recessed portion are combined into an integrated fastening system. The multiple insertion holes are arranged within a single fixing plate structure that fits into the recessed portion, merging multiple fastening functions into one unified component assembly. This reduces the number of separate parts and simplifies the overall structure while maintaining multiple fastening points for enhanced reliability.
Solution Approach 2:
The fixing plate serves multiple functions simultaneously: it provides structural support, contains multiple insertion holes for fastening, and is disposed within the recessed portion for proper positioning. This multi-functional design achieves secure attachment with multiple fastening points without requiring separate components for each function, thereby reducing structural complexity while maintaining high reliability.

AI summary
A protector includes: a protector main body covering the lower portion of the vehicle body and a fixing plate for fixing the protector main body to the vehicle body. The protector main body has a surface portion and a recessed portion recessed from the surface portion to the vehicle body. The fixing plate has a plurality of the first insertion holes through which the fastening members for securing the protector main body to the vehicle body are passed. The recessed portion has second insertion holes through which fastening members are passed. The fixing plate is disposed in the recessed portion. The plurality of the first insertion holes are formed apart from one another.
