Elastic Hand Loop for Adjustable Grip Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand holding devices for stick handles, such as ski poles and Nordic walking sticks, are limited in their ability to accommodate both lateral and overhead gripping positions, particularly due to the short distance between the holding mandrel and the hand holding device, making it difficult for users to switch between grip positions effectively on varying terrain.
Innovation Solution
A hand holding device with an elastic strip that self-locks onto the stick handle, allowing for adjustable length and comfortable gripping from both lateral and overhead positions, featuring a first elastic strip on the outer surface and a non-elastic strip on the palm side, along with a second strip connecting the thumb and fingers, enabling efficient grip changes based on terrain or movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional hand holding device with fixed length is used, then the structure is simple, but the user cannot effectively switch between lateral and overhead grip positions on varying terrain
Solution Approach 1:
The hand holding device incorporates an elastic strip that can dynamically change its length and configuration. The elastic strip includes a first region that can be extended or compressed, allowing the device to adapt between lateral and overhead grip positions. This dynamic flexibility enables the coupling element to maintain proper positioning relative to the user's hand regardless of the gripping orientation, thereby resolving the contradiction between adaptability and structural simplicity.
Solution Approach 2:
The invention changes the physical parameter of the strip's elasticity and length. By incorporating an elastic strip with a first region that can change its length, the device allows the distance between the coupling element and the hand to be adjusted. This parameter change enables the same device to function effectively in both lateral and overhead grip positions, achieving versatility without requiring multiple separate devices or complex mechanisms.
2Reliability
If the distance between the holding mandrel and hand holding device is reduced, then the attachment is secure, but the user experiences discomfort when gripping from overhead positions
Solution Approach 1:
The elastic strip provides a dynamic solution that maintains secure attachment while accommodating overhead grip positions. When the user grips from above, the elastic strip can extend or reconfigure, increasing the effective distance between the coupling element and the hand. This dynamic adjustment ensures that the attachment remains secure during lateral grips while providing sufficient flexibility and comfort for overhead positions, thereby resolving the contradiction between attachment security and operational comfort.
3Adaptability or versatility
If an elastic strip is added to allow grip position changes, then adaptability improves, but the device complexity increases
Solution Approach 1:
The elastic strip is designed with differentiated local qualities: a first region with elastic properties for adaptability, and potentially a second region with different characteristics for structural support. This local differentiation allows the strip to provide the necessary flexibility for grip position changes while maintaining overall structural integrity. By concentrating the elastic properties in specific regions rather than throughout the entire strip, the design achieves adaptability with minimal increase in overall device complexity.
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
Enables comfortable and practical gripping from both lateral and overhead positions, distributing load effectively and allowing for easy transition between grip styles without compromising comfort or security, enhancing user experience on different terrains.
Implementation Method 1
the first strip is designed to be elastic at least in some areas. The elasticity of the first strip to which the coupling element is attached allows a user to grip the handle head of the stick from above
