Adjustable Buckle for Ski Pole Wrist Strap Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buckles for wrist straps on sporting poles are not adjustable, leading to unsuitable wrist and hand positions and difficulties in quickly regaining control of the pole after losing grip.
Innovation Solution
A buckle with two opposing elements and locking means that allow the tape to be fixed at different positions, enabling adjustable distance between the wrist strap and handgrip, and featuring hinge and hooking mechanisms for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the tape is permanently associated with the inside of the buckle, then the buckle structure is simple, but it is impossible to vary the mutual distance between the wrist strap and the handgrip
Solution Approach 1:
The buckle is divided into two separate elements: a first element and a second element. The tape can be positioned between these elements at different locations, enabling adjustment of the wrist strap distance from the handgrip. This segmentation allows the tape-buckle connection to be variable rather than permanent, resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The buckle transitions from a static, permanently fixed structure to a dynamic, adjustable structure. The two elements can be moved relative to each other along the tape, allowing the user to change the distance between the wrist strap and handgrip based on different usage conditions and personal preference.
2Ease of operation
If the distance between wrist strap and handgrip is fixed, then the buckle design is simple, but the user may be obliged to hold wrist and hand in an unsuitable position
Solution Approach 1:
By separating the buckle into two elements with the tape running between them, the design enables adjustable positioning. Users can set the optimal distance for their wrist and hand position, improving ease of operation while accepting increased structural complexity.
3Speed
If the distance between hand and handgrip is unsuitable, then the buckle structure remains simple, but the user cannot rapidly regain hold after losing control
Solution Approach 1:
The dynamic adjustment capability allows users to optimize the wrist strap distance for rapid control recovery. By enabling variable positioning rather than a fixed simple structure, users can achieve faster regaining of control while accepting the complexity of the adjustment mechanism.

AI summary
The invention is a buckle (1; 100; 200) for connecting a wrist strap (P) to the handgrip (M) of a pole (P) for sporting activities such as skiing, trekking and the like. Said buckle (1; 100; 200) comprises a body (2; 102; 202) consisting of an outer jaw (3; 103; 203) and an inner jaw (4; 104; 204) between which it is possible to identify locking means (5; 105; 205) suited to cooperate with a tape (F) forming part of the wrist strap (P) and arranged in different positions between the outer jaw (3; 103; 203) and the inner jaw (4; 104; 204) in order to retain the wrist strap (P) at different distances from the handgrip (M).
