Handlebar Holder With Elastic Strap Loop For Wristband Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handlebar accessories for wristop computers are cumbersome to fasten and remove, requiring significant force and often lead to material degradation over time due to repeated assembly and disassembly, necessitating frequent replacement.
Innovation Solution
A holder with a stretchable elastic loop and a durable plastic structure featuring a plate-like middle portion, bent outer portions, and recesses for secure attachment to the handlebar, allowing easy installation and minimal wear on the accessory, with a soft mounting pad and friction strips for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If clamps are tightened to the handlebar by screws or adjustable means, then the attachment is secure, but the fastening and removal process becomes tedious and time-consuming
Solution Approach 1:
The holder is divided into a stationary plate-like middle portion and flexible bent outer portions that can independently deform. This segmentation allows the outer portions to flex during attachment/detachment while the middle portion remains fixed, enabling quick release without unscrewing components
Solution Approach 2:
The bent outer portions are designed to be flexible and deformable, allowing them to dynamically adapt during the attachment and removal process. This flexibility enables the holder to be quickly secured to and released from the handlebar without requiring time-consuming screw adjustments
2Reliability
If force is applied to press the accessory onto the handlebar, then the attachment is firm, but significant force is needed for installation and removal
Solution Approach 1:
The bent outer portions are designed to flex and deform under applied force, allowing easy attachment and removal. The elastic material absorbs the force during installation and releases it during removal, significantly reducing the effort needed compared to rigid clamps
Solution Approach 2:
The holder utilizes elastic properties of the material, changing from a rigid structure to a flexible one that can deform. This parameter change allows the holder to be pressed onto the handlebar with minimal force while maintaining firm attachment through elastic recovery
3Reliability
If screws and adjustable means are used for fastening, then the attachment is secure, but the accessory experiences material degradation over time
Solution Approach 1:
The invention replaces the mechanical screw-and-thread system with an elastic deformation-based attachment mechanism. This substitution eliminates the wear and material degradation associated with repeated screwing and unscrewing, significantly extending the accessory's service life
Solution Approach 2:
The attachment mechanism changes from a mechanical threading system to an elastic deformation system. This parameter change eliminates the contact wear and stress concentration points that cause material degradation in screw-based systems, extending the durability of the accessory
4Reliability
If the wristop computer is held by its own wristband strapped around the accessory, then the device is secured, but the fastening process becomes more complex
Solution Approach 1:
The holder integrates both the mounting function (plate-like middle portion for handlebar attachment) and the device securing function (bent outer portions for wristband support) into a single unified structure. This merging eliminates the need for separate fastening components, simplifying the overall system while maintaining secure device attachment
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 provides a simple, secure, and durable fastening system that reduces the force required for installation and removal, minimizes wear on the accessory, and allows for easy replacement of the elastic strap, ensuring long-term functionality and lightweight design.
Implementation Method 1
a band of stretchable material forming an elastic loop
Implementation Method 2
the first recess for the handlebar may be provided with friction strips made of a material that is also softer than the holder

AI summary
The invention relates to arrangements for holding a wristband device attached to a handlebar, such as a bicycle handlebar. The arrangement comprises a holder and a strap of a stretchable material forming an elastic strap loop. The holder comprises a plate-like middle portion having a flat surface on the top side to support the housing of said electronic device, and a first recess on the opposite bottom side for interfacing with a handlebar. It also comprises first and second bent outer portions attached to opposite ends of said middle portion adapted to support at least part of said wristband of said electronic device, and a pair of second recesses formed on the top side of said middle portion at its opposite ends between the middle portion and said outer portions, respectively. The holder is attached to the handlebar with the first recess mating with the handlebar and the elastic strap loop wrapped around the handlebar with a first end fitted in a first recess and the other end of said strap fitted in the second recess of said pair of second recesses.
