Angled Bicycle Grip Shaft for Wrist Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handlebar grips for two-wheeled vehicles, such as bicycles, lack ergonomics, leading to increased articular stresses and discomfort during prolonged use due to inadequate support for the wrist, resulting in pain and joint wear.
Innovation Solution
A grip with a cylindrical main body and integral shaft angled between 30° and 60°, providing a wider support surface for the carpus and palm, and an abutment for additional support, designed to align the wrist bones optimally, reducing pressure on joints and preventing slipping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional cylindrical grips are used on handlebars, then the structure is simple and easy to manufacture, but the grip surface area is insufficient and does not provide adequate wrist support
Solution Approach 1:
The grip transitions from a conventional single-dimensional cylindrical shape to a multi-dimensional structure with a main body, angled shaft, and abutment. This dimensional expansion creates multiple support surfaces (palm rest on main body, wrist supported by abutment, fingers on shaft) that collectively provide adequate wrist support while maintaining manufacturing simplicity through integral molding.
Solution Approach 2:
The grip is segmented into distinct functional zones: a main body for palm support, a shaft at an angle for finger placement, and an abutment for wrist support. This segmentation allows each component to serve its specific ergonomic function while being manufactured as a single integrated piece, resolving the contradiction between increased surface area and structural complexity.
2Ease of operation
If the grip portions are rectilinear and perpendicular to the frame, then the manufacturing is simple, but the wrist alignment is poor and causes articular stresses
Solution Approach 1:
The shaft angle parameter is changed from the conventional 0° (perpendicular to frame) to an optimal range of 30°-60°. This parameter modification aligns the wrist bones properly during gripping, reducing articular stresses and improving comfort. The angled configuration is achieved through integral molding, maintaining manufacturing simplicity while dramatically improving ergonomic performance.
3Reliability
If conventional grips are used, then the structure is straightforward, but prolonged use causes pain and joint wear due to inadequate wrist support
Solution Approach 1:
The abutment acts as an intermediary element between the handlebar and the user's wrist. It provides a dedicated support surface that distributes wrist pressure, preventing direct transmission of forces to the carpus bones. This intermediary structure reduces articular stresses and joint wear during prolonged use, while the integral construction keeps the overall device complexity low.

AI summary
Disclosed is a grip (1) for the handlebars (3) of a two-wheeled vehicle and in particular of a bicycle, including an essentially cylindrical main body (2) capable of fitting onto a portion of the handlebars (3) that is rectilinear and essentially perpendicular to the frame of the vehicle. The grip (1) also includes a shaft (4) that is integral with the main body (2), forming an angle with the longitudinal axis of the handlebars of between 30° and 60°, and equipped with an abutment (5) at its free end.
