Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional extension handlebars for bicycles lack the ability to adjust the grip position to match different user palm shapes, leading to suboptimal ergonomic and aerodynamic conditions.
Innovation Solution
An adjustable extension handlebar structure that allows for adjustable distance between the griping body and the base, and rotational adjustment of the griping body left or right, enabling a closer fit to individual palm shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the extension handlebar is designed with fixed structure, then the manufacturing simplicity is maintained, but the adaptability to different user palm shapes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed handlebar structure into an adjustable one. The griping body is made movable relative to the base through a pivot connection, allowing it to rotate and adjust to different positions. This enables the handlebar to adapt to different user palm shapes while maintaining a relatively simple overall structure through controlled mobility rather than complete rigidity.
Solution Approach 2:
The patent segments the handlebar into distinct functional modules: a base, a griping body, and a pivot connection mechanism. This segmentation allows each component to be optimized independently - the base provides structural support, the griping body provides the gripping surface, and the pivot enables adjustment. The modular design achieves adaptability without requiring complete structural complexity.
2Ease of operation
If the griping body is made adjustable in multiple directions, then the ergonomic performance is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamics by enabling the griping body to rotate around the pivot axis, transforming a static gripping surface into a dynamically adjustable one. This single rotational degree of freedom provides sufficient ergonomic adjustment for most users without requiring complex multi-axial adjustment mechanisms, thus improving ergonomics while controlling structural complexity.
Solution Approach 2:
The patent applies parameter changes by allowing the position and orientation of the griping body to vary through rotation around the pivot. This changes the spatial parameters (position and angle) of the gripping surface to match different user hand positions and palm shapes, improving ergonomic performance through parameter variability rather than structural complexity.
3Adaptability or versatility
If the base is pivotally connected with a pivot not parallel to the extension direction, then the rotational adjustment capability is improved, but the structural simplicity deteriorates
Solution Approach 1:
The patent employs asymmetry by positioning the pivot axis perpendicular to the extension direction rather than parallel to it. This asymmetric pivot orientation enables the griping body to rotate in a plane that is perpendicular to the handlebar's longitudinal axis, providing adjustment capability that matches natural hand positioning angles. The asymmetric design achieves superior adjustability without requiring symmetric, multi-axial complexity.

AI summary
A structure of an adjustable extension handlebar is provided. The structure comprises an extension module and a griping module. The extension module comprises an extension body having an extension portion and a fixing portion. The extension portion extends from the fixing portion in a direction away from a handlebar. The griping module comprises a base and a griping body. A gap is formed between the base and the griping body, and the base and the griping body are connected through a first fastener. A distance and a rotation angle between the griping body and the base are adjustable, so that the griping body can more closely match palm shapes of different users.
