Pivotable Wrist Strap Disconnect for Pole Grip Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional grip devices for poles, such as those used for skiing or hiking, can cause wrist or hand injuries when the user falls or the pole is stuck, as the pole remains strapped to the wrist, leading to potential harm.
Innovation Solution
A grip device with a wrist strap unit featuring a connecting member that is pivotable between locked and unlocked positions, allowing for secure attachment during use and automatic release when the user loses grip or the pole is stuck, preventing injuries by disconnecting from the wrist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wrist strap is fixed to the grip body, then the grip firmness is improved, but the risk of wrist or hand injuries increases when the user falls or the pole is stuck
Solution Approach 1:
The connecting member is designed to be pivotable between a locked position (providing secure attachment) and an unlocked position (allowing release). The tail part can rotate relative to the head part, enabling the wrist strap to dynamically transition from a constrained state that ensures grip firmness to a released state that prevents injuries during falls or pole entrapment
Solution Approach 2:
The connection state of the wrist strap is changed from fixed to variable. By allowing the connecting member to pivot between locked and unlocked positions, the system changes the parameter of connection rigidity, providing both secure attachment during normal use and automatic release capability during emergency situations
2Reliability
If the wrist strap is fixed to the grip body, then the pole retention is improved, but the ease of operation deteriorates when quick release is needed
Solution Approach 1:
The pivotable connecting member enables dynamic operation where the user can easily transition between locked and unlocked states. The tail part's rotational capability allows quick release by simply pivoting the connecting member, providing both secure retention during use and rapid release when needed
3Reliability
If the connecting member is retained in the connecting space, then the security of attachment is improved, but the ability to separate when needed deteriorates
Solution Approach 1:
The connecting member's pivotable design allows it to adapt between two states: retained in the connecting space for secure attachment, and separated from the connecting space for release. The tail part's rotation enables the system to switch between these states based on operational needs
Solution Approach 2:
The connecting member is divided into a head part (engaging with the connecting space) and a tail part (pivotable connection to the wrist strap). This segmentation allows the head part to provide secure retention while the tail part provides the pivoting motion necessary for both locking and releasing the connection

AI summary
A grip device for a pole includes a grip and a wrist strap unit. The grip has a connecting part that defines a connecting space therein, and that has a lower portion and a protruding portion disposed in the connecting space. The wrist strap unit includes a connecting member that engages removably the connecting space, and that has a tail part. The tail part is pivotable between a locked position, where the tail part is adjacent to the lower portion so that the connecting member is retained in the connecting space by the protruding portion, and an unlocked position, where the tail part is away from the lower portion and the protruding portion so that the connecting member is permitted to be separated from the connecting part.
