Straddle-Type Vehicle Side Grill Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Scooter-type motorcycles face damage to their body covers due to rider contact, leading to costly and difficult replacements, as the covers are large, cumbersome, and require complex attachment structures.
Innovation Solution
A detachable side grill is integrated into the main body cover, positioned below the seat to act as a sacrificial element, protecting the main body cover from rider contact and featuring a convex shape to prevent direct impact, with internal fixation to prevent unauthorized removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the main body cover is made large and comprehensive to protect the body frame and storage box, then the protection function is improved, but the ease of repair deteriorates because replacing the entire cover is expensive and difficult
Solution Approach 1:
The patent divides the main body cover into multiple separate body cover portions (first body cover portion, second body cover portion, third body cover portion, etc.), each covering different areas of the body frame. This segmentation allows individual portions to be replaced independently rather than replacing the entire cover, significantly improving ease of repair while maintaining comprehensive protection.
2Reliability
If the body cover is made large and comprehensive to protect the body frame and storage box, then the protection function is improved, but the manufacturing cost increases due to material costs and complex attachment structures
Solution Approach 1:
By segmenting the body cover into multiple smaller portions, each portion requires less material and can be manufactured more simply. The attachment structures for each portion are also simpler and fewer in number compared to a single comprehensive cover, reducing overall manufacturing costs while maintaining protection functionality.
3Reliability
If the side grill is arranged to extend beyond the main body cover outline, then the protection against rider contact is improved, but the aerodynamics and aesthetics deteriorate due to excess contact area
Solution Approach 1:
The side grill is positioned specifically at the lower lateral side of the body cover where rider contact most frequently occurs. This localized placement provides protection exactly where needed without extending beyond the body cover outline, thereby maintaining aerodynamic efficiency and aesthetic appearance while still fulfilling the protection function.
