Bicycle Grip With Oblique Plug And Bayonet Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bicycle grips with end caps are limited in their adaptability, as they are designed to fit only angled handles and do not protect the gripping part from damage, and lack a universal plug for attaching accessories like rear-view mirrors.
Innovation Solution
A sleeve with a receiving area at an oblique angle to the central axis, allowing a plug to be inserted and secured via a bayonet lock, enabling compatibility with both angled and straight handles, and providing protection and easy attachment of accessories.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the end cap is adapted to the angled shape of the sleeve, then it can be inserted into the angled sleeve, but it can only be used for handles with angled cuts and not for other handles
Solution Approach 1:
The patent applies universality by designing a single plug with a cylindrical receiving area that can accommodate both angled and straight handles. The plug's receiving area is designed with an oblique central axis that allows it to fit angled sleeves, while the cylindrical shape also permits insertion into straight-cut sleeves, making one plug design universally compatible with different handle types.
2Object-affected harmful factors
If the end cap is designed to fit the angled sleeve, then it matches the handle shape, but it does not protect the gripping part from damage
Solution Approach 1:
The patent applies asymmetry by designing the plug's central axis of the receiving area to be oblique rather than perpendicular to the sleeve's central axis. This asymmetric orientation allows the plug to extend beyond the sleeve's end in a direction that provides protective coverage for the gripping part, while still maintaining compatibility with the angled sleeve geometry.
3Adaptability or versatility
If a single plug is designed to work with both angled and straight handles, then versatility is improved, but the connection reliability may be compromised
Solution Approach 1:
The patent applies self-service through the bayonet lock mechanism, where the plug automatically locks into the sleeve upon insertion and rotation. The locking elements engage automatically without requiring additional fastening steps, providing a reliable self-securing connection that maintains stability regardless of whether the handle is angled or straight.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for a universally usable system where a single plug can be attached to both angled and straight handles, protecting the sleeve from damage and facilitating easy accessory attachment.
Implementation Method 1
The plug is positively connected to the sleeve, in particular via a bayonet lock
Implementation Method 2
By tightening the clamp, the grip can be frictionally secured to the handlebar

AI summary
The disclosure relates to a grip (1) for a bicycle handlebar, comprising a sleeve (10) that can be slid onto the handlebar. The sleeve (10) defines a central axis mH that coincides with the central axis of the bicycle handlebar. A plug (20) serving as an end cap or earpiece receptacle is inserted into the sleeve (10). For this purpose, the sleeve (10) includes a receiving area (12) for the plug (20). A central axis mA of the receiving area (12) is set at an oblique angle α to the central axis mH.
