Saddle Riding Vehicle Bumper Width Variation for Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle bumpers lack enhanced functionality and improved external appearance, particularly in terms of rigidity and design integration with the body's front portion.
Innovation Solution
A vehicle bumper design featuring upwardly and downwardly extending frame portions, a transversely extending portion, and U-shaped bumper main portions that increase in width toward the upper part, integrating with a skid plate and radiator grille for improved protection and aesthetic integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the bumper is made with a constant thickness tube, then the manufacturing is simple, but the rigidity and functionality are insufficient
Solution Approach 1:
The bumper is divided into multiple functional components: upwardly/downwardly extending frame portions for structural support, a transverse extending portion for lateral connectivity, and bumper main portions for coverage and aesthetic function. Each segment serves specific mechanical and design purposes, allowing the constant thickness tube to achieve enhanced rigidity through strategic structural division rather than uniform thickening.
2Strength
If the bumper area is increased to improve rigidity, then the protection capability is enhanced, but the external appearance may be compromised
Solution Approach 1:
The bumper main portions are designed with varying widths - narrower at the lower portion and wider at the upper portion - creating local quality variations that simultaneously improve rigidity (through increased upper width) and maintain aesthetic appeal (through the tapered profile that integrates with the vehicle's front design). This local differentiation allows the bumper to achieve both structural and cosmetic objectives.
3Area of stationary object
If the bumper main portions increase width toward the upper part, then the rigidity and area are improved, but the manufacturing complexity increases
Solution Approach 1:
The bumper main portions utilize parameter changes by progressively increasing the width from lower to upper sections. This gradual parameter variation achieves increased bumper area and rigidity while maintaining manufacturability, as the tapered shape can be produced using standard forming processes without requiring complex multi-component assemblies or specialized manufacturing techniques.

AI summary
A vehicle is provided which includes a bumper that holds an enhanced functionality and realizes an improvement in its external appearance. A saddle riding vehicle includes a front bumper having a shape which covers a periphery of at least a headlamp when seen from the front at a front portion of the vehicle. The front bumper includes a pair of left and right upwardly/downwardly extending frame portions configured to extend in an up-down direction, a transversely extending portion configured to extend in a vehicle's width direction to surround the periphery of the headlamp, and a pair of left and right bumper main portion configured to cover the left and right upwardly/downwardly extending frame portions from the front thereof, and the bumper main portions are configured to increase their widths in the vehicle's width direction toward the upper part.
