Pole Wrist Strap Locking Mechanism for One-Handed Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wrist strap fastening devices for sports equipment require complex operations, often needing two hands or dexterity, are difficult to manufacture, and prone to malfunction, especially when gloves are worn.
Innovation Solution
A ground support device with a handle and wrist strap featuring a simple, one-handed operable locking element that moves between locked and unlocked positions, using a single piece locking mechanism with elastic retention and accessible surfaces for easy operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If complex removable fastening devices are used between the wrist strap and the stick, then the wrist strap can be detached while keeping the strap on the hand, but the fastening devices require two hands to operate or considerable dexterity, making them difficult to use when wearing gloves or with numb fingers
Solution Approach 1:
The locking element is divided into distinct functional parts: a body for engagement, a retaining element with an elastic portion for locking action, and a bearing surface for user actuation. This segmentation allows each part to perform its specific function efficiently while maintaining overall simplicity.
Solution Approach 2:
The elastic portion automatically returns the retaining element to its locked position after being actuated, eliminating the need for additional mechanisms to reset the locking system. The system serves itself by using the stored elastic energy to maintain the locked state.
2Reliability
If complex removable fastening devices with numerous parts are used, then the wrist strap can be securely attached, but the devices become difficult to manufacture and assemble, and increase the risk of malfunction during use
Solution Approach 1:
The locking element integrates multiple functions into a single component: the body provides structural support, the retaining element performs the locking action, and the elastic portion provides both the locking force and the return mechanism. This merging reduces the total number of parts while maintaining reliability.
Solution Approach 2:
The locking element serves multiple purposes: it secures the wrist strap to the stick, provides a one-handed actuation mechanism, and automatically maintains the locked position through its elastic portion. This multi-functionality eliminates the need for separate components for each function.
3Reliability
If traditional fastening devices are used, then the wrist strap can be attached to the stick, but the user must manipulate the fastening with two hands or significant dexterity, which is problematic when wearing gloves or with numb fingers
Solution Approach 1:
The bearing surface is specifically designed with appropriate friction characteristics and geometric shape to be easily actuated by a single thumb or finger. The local properties of this surface (its shape, material, and position) are optimized for operation under gloves or with reduced dexterity, while the rest of the locking element maintains its structural integrity for secure attachment.
