Tapered Hand Grip Mounting Without Visible Fasteners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for affixing hand grips to tools using different materials face limitations in securing and maintaining the grip effectively, often requiring fasteners that can be cumbersome and unsightly.
Innovation Solution
A deformable handle with recesses and a hand grip featuring angled end surfaces and channels or projections, allowing secure mounting through deformation of handle ends to engage with the grip, preventing removal without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners like rivets or screws are used to affix hand grips to handles, then the hand grip attachment is secure, but the mounting process becomes cumbersome and the appearance is less aesthetically pleasing
Solution Approach 1:
The invention extracts and eliminates the fasteners (rivets, screws, or other fastening elements) from the mounting system. The hand grip is designed with a tapered configuration that fits into a corresponding recess in the handle, creating a secure attachment without requiring any external fastening components. This removes the cumbersome fastening process while maintaining secure attachment.
Solution Approach 2:
The invention merges the hand grip and handle into a unified structure where the tapered hand grip is integrated directly into the handle recess. The channel feature on the hand grip engages with the rib feature on the handle, creating an integrated assembly that eliminates the need for separate fastening components and simplifies the mounting process.
2Reliability
If fasteners are used to affix hand grips to handles, then the attachment is secure, but the surface finish becomes less smooth and aesthetically pleasing
Solution Approach 1:
The invention removes fasteners from the attachment system, eliminating the visual disruption they cause on the handle surface. The tapered hand grip fitting into the recess creates a clean, flush surface that maintains the aesthetic quality of the handle while ensuring secure attachment through the tapered geometry and channel-rib engagement.
3Ease of operation
If hand grips are made of softer materials like wood or plastic, then user comfort is improved, but the attachment to hard metal handles becomes more difficult
Solution Approach 1:
The invention applies different geometric features to different parts of the hand grip and handle interface. The hand grip has a tapered configuration with a channel feature, while the handle has a corresponding recess with a rib feature. This localized geometric differentiation creates effective engagement between the softer hand grip material and the hard metal handle, facilitating secure attachment without requiring fasteners.

AI summary
An apparatus having a handle with a mounted hand grip is described. A first end wall surface of the hand grip is tapered from a base surface to a top surface of the hand grip. A second end wall surface of the hand grip is tapered from the base surface to the top surface of the hand grip. A first end wall of the recess engages the first end wall surface of the hand grip and prevents movement of the first end wall surface away from the base surface of the recess. A second end wall of the recess engages the second end wall surface of the hand grip and prevents movement of the first end wall surface away from the base surface of the recess.
