Removable Hand Grip With Protrusion Insertion Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand grips for handlebars, such as those on baby strollers, are either fixed and difficult to replace or removable but prone to movement and lack stability and comfort.
Innovation Solution
A hand grip design featuring elongated coupling members with protrusions that insert into holes or recesses on the handlebar, providing a secure attachment without screws, allowing for easy removal and customization, and incorporating a cover with a foam or protection layer for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If removable hand grips are attached around a handle bar without open ends, then the grip can be removed for cleaning or customization, but the grip easily rotates or moves with respect to the handlebar
Solution Approach 1:
The coupling mechanism is divided into discrete components: protrusions on the grip and corresponding holes/recesses on the handlebar. This segmentation allows the grip to be divided into removable segments while maintaining stable positioning when assembled, resolving the contradiction between removability and position stability.
Solution Approach 2:
The protrusions are inserted into holes or recesses of the handlebar, creating a nested structure where the grip components fit within the handlebar geometry. This nesting provides stable positioning while maintaining the ability to remove the grip by extracting the protrusions from their recesses.
2Stability of the object's composition
If threads and screws are used to attach the hand grip to the handle bar, then the grip is stable and secure, but the grip is difficult to install for a non-technical person
Solution Approach 1:
The complex threading and screwing operations are extracted and replaced with simple protrusion insertion. The attachment mechanism takes out the need for rotational fastening and instead uses direct linear insertion of protrusions into holes, making installation trivial for non-technical users while maintaining stable attachment.
Solution Approach 2:
The mechanical screw-and-thread system is substituted with a simpler protrusion-into-hole insertion system. This replacement eliminates the need for rotational motion, threading knowledge, and specialized tools, thereby improving ease of operation while maintaining attachment stability through the geometric interlocking of protrusions and recesses.
3Stability of the object's composition
If fixed hand grips are provided on the handle bar, then the grip offers comfort and stability, but the grip cannot be replaced when deteriorated or for customization
Solution Approach 1:
The attachment system transitions from a permanent fixed state to a dynamic state where the grip can be easily moved between attached and removed conditions. The protrusion-hole mechanism allows the grip to be dynamically repositioned or replaced while maintaining stable attachment when in use, enabling both comfort during operation and replaceability when needed.

AI summary
Some embodiments are directed to a hand grip for wrapping around a handlebar. The hand grip includes a first elongated coupling member, a second elongated coupling member, and a cover arranged between the first elongated coupling member and the second elongated coupling member. The first and/or second elongated coupling member include one or more protrusions arranged to be inserted into one or more holes or recesses of the bar. The hand grip can easily be attached to for example a handlebar of a baby stroller, and can easily be removed.
