Triangular Hand Strap with Non-Slip Protrusions for Sports Poles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand straps for sports poles fail to provide a stable grip, allowing the strap to rotate around the wrist and making it difficult for athletes to regain hold on the handle after releasing their grip, even with additional thumb straps that use snap fasteners for quick release.
Innovation Solution
A hand strap with a substantially triangular shaped band and non-slip protruding elements that integrate with the athlete's hand, using Velcro and snap fasteners to secure the strap to the wrist and thumb, preventing rotation and ensuring alignment with the handle for easy re-grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hand strap is made as a flexible ring surrounding the hand, then it allows easy insertion and basic grip support, but it rotates freely around the wrist when grip is released
Solution Approach 1:
The hand strap is divided into multiple functional segments: a wrist-engaging portion with protruding elements for preventing rotation, a thumb strap portion with fastening means for securing the thumb, and connection means linking these portions. This segmentation allows each part to perform its specific function independently while working together to solve the overall problem of grip stability.
Solution Approach 2:
The hand strap employs asymmetric design elements including protruding elements on one side of the wrist portion and a specifically oriented thumb strap that wraps around the thumb in a defined direction. This asymmetry prevents the strap from rotating symmetrically around the wrist, as the protruding elements create directional engagement that resists rotation in both directions.
2Stability of the object's composition
If a thumb strap with snap fastener is added to prevent rotation, then grip stability improves during sport, but quick release capability is lost when the fastener is released
Solution Approach 1:
The thumb strap is pre-configured to wrap around the thumb in a specific direction, and the fastening means is positioned to engage automatically when the thumb is inserted. This preliminary arrangement ensures that once the thumb is placed in the strap, the anti-rotation function is immediately activated without requiring additional adjustment or tightening actions by the user.
Solution Approach 2:
The hand strap transitions from a static flexible ring to a dynamic system with movable fastening means that can be engaged or disengaged. The thumb strap portion can be adjusted to different positions on the thumb, and the fastening means can be quickly engaged or released, allowing the strap to adapt between secured and released states based on operational needs.
3Stability of the object's composition
If the strap is secured tightly to prevent rotation, then stability improves, but the strap becomes difficult to adjust and remove
Solution Approach 1:
The hand strap is designed to be self-adjusting through the interaction of its components: the protruding elements automatically engage with the wrist when the strap is pulled on, and the thumb strap naturally positions itself around the thumb. The fastening means requires minimal user intervention to engage or disengage, allowing the strap to secure itself while maintaining simplicity.
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 hand strap provides a more stable and secure grip on the handle, allowing athletes to easily and quickly re-establish their hold, enhancing performance and safety during sports activities.
Implementation Method 1
non-slip protruding elements which project from the surface of the shaped band towards the hand or glove of the athlete wearing the hand strap, the purpose of which is to prevent any rotation of the hand strap
Implementation Method 2
Velcro and snap fasteners to secure the strap to the wrist and thumb
