Bicycle Handlebar Support with Common Grip Element
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle handlebar trailers for time and triathlon bicycles result in aerodynamically unfavorable positions that increase air resistance and fatigue, due to large frontal areas and uncomfortable hand positions, leading to frequent grip changes and delayed control operation.
Innovation Solution
A bicycle handlebar trailer with a central holding element and laterally arranged armrests, featuring a common asymmetric handle element that can be gripped by both hands, with thumb rests and easily accessible switching elements, reducing air resistance and improving ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two separate tubular elements with individual grip elements are used, then each hand has its own grip position, but the frontal area increases leading to high air resistance
Solution Approach 1:
The patent merges two separate tubular elements with individual grips into a single common grip element that serves both hands. This consolidation reduces the frontal area and eliminates the gap between separate grips, thereby reducing air resistance while still providing adequate grip positions for both hands on the same aerodynamic structure.
Solution Approach 2:
The patent transitions from a two-dimensional arrangement of separate parallel tubes to a three-dimensional integrated structure where the common grip element provides multiple grip positions at different heights and angles, allowing both hands to find comfortable positions on a single aerodynamic form.
2Object-affected harmful factors
If the distance between grips is minimized for aerodynamics, then air resistance decreases, but hand position flexibility and ergonomics are reduced
Solution Approach 1:
The common grip element extends in multiple dimensions with varying diameters and provides grip positions at different heights, angles, and locations along its length. This multi-dimensional design allows both hands to find comfortable positions while maintaining a compact overall structure that minimizes frontal area and air resistance.
3Object-affected harmful factors
If a common grip element is used for both hands, then air resistance is reduced, but control accessibility may be compromised
Solution Approach 1:
The common grip element is segmented into multiple functional zones along its length, with different diameters and surface characteristics. Control elements are strategically positioned at specific segments where they can be easily accessed by either hand, while the aerodynamic profile is maintained in other segments. This segmentation allows both aerodynamic efficiency and control accessibility to coexist.
