Hand Grip Sport Strap V-Area Design for Adjustable Wrist Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hand gripping devices for sports and weight lifting cause discomfort and use issues due to full wrist encirclement and lack of adjustability, leading to inadequate grip strength and control.
Innovation Solution
A hand grip sport strap design that contacts only the back of the hand about 180° below the wrist joint, featuring a 'V' area with adjustable non-slip material and braided elastic for secure grip and easy adjustment, available in multiple sizes to fit various users, allowing for easy application and release of objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the strap material encircles the wrist joint 360° as in conventional designs, then the grip strength is improved, but the comfort in the wrist area deteriorates and the device becomes difficult to adjust
Solution Approach 1:
The strap is segmented into two distinct functional zones: a 360° encircling portion that provides grip strength, and a 180° contact portion with the V-area that provides comfort and adjustability. This segmentation allows each zone to perform its specific function without the drawbacks of the other.
Solution Approach 2:
Different portions of the strap have different qualities: the encircling portion is designed for strength and security, while the V-area portion is designed for comfort and adjustability. The V-area specifically has non-slip material for control and a curved seam for anatomical comfort.
2Reliability
If the strap is tightly secured around the wrist as in conventional designs, then the grip control is improved, but the ease of operation and adjustability deteriorates
Solution Approach 1:
The strap transitions from a static, fixed-tightness design to a dynamic, adjustable design. The V-area allows the user to easily adjust the tightness and position of the strap during use, enabling the device to adapt to different grip requirements and comfort levels.
Solution Approach 2:
The user can independently adjust the strap's tightness and position using the V-area without requiring assistance or complex mechanisms. The non-slip material and curved seam design enable the user to make adjustments while maintaining grip control.
3Ease of manufacture
If a single size strap is used for all users, then the manufacturing cost is reduced, but the adaptability to different hand sizes deteriorates
Solution Approach 1:
The V-area design with its curved seam and non-slip material creates a universal interface that adapts to different hand sizes and shapes. The adjustable nature of the V-area allows a single strap size to serve multiple user groups (men, women, different hand sizes) effectively.
4Strength
If the strap material provides high friction for secure grip, then the grip strength is improved, but the ease of adjustment before or during the event deteriorates
Solution Approach 1:
The non-slip material is applied specifically in the V-area where adjustment is needed, while other portions of the strap maintain their original friction characteristics for secure gripping. This localized application of high-friction material provides both adjustability and grip strength.
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
Enhances grip strength and control with reduced wrist fatigue, providing durable, comfortable, and adjustable support for a wide range of users and activities, including weight lifting and other sports, while ensuring the strap remains secure when not in use.
Implementation Method 1
The material covering the strap material in the 'V' area provides a durable wear surface with just enough slip so the hand and fingers can make any adjustment needed
Implementation Method 2
The 'V' area has a natural curve because of the way the two ends of the strap material are sewn together

AI summary
A hand gripping sport strap used to grip a bar or handle. One piece of strap material with two ends. Each end has two sides. The two ends are overlapped, forming a perpendicular right angle with each end placed in line with one side of the other end and secured. A 90° angle tip is formed with both ends and two sides of strap material. This tip made with two layers of strap material is now cut off making an adjustment area. The inside and outside of this adjustment area is then covered with a high-wear resistant and non-slip material, now referred to as the V area when completed. A loop of strap material created by bringing the two ends together will go on the back of the hand with the V area positioned in the palm of the hand after the hand and all five fingers are put through the loop of the strap material.
