Ergonomic Hand Grip with Contoured Surfaces for Posture Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand grip elements do not effectively promote a natural and physiological alignment of the hands and forearms, leading to poor posture and reduced vitality during activities like walking and running.
Innovation Solution
A hand grip element with an elongated body featuring multiple shaped surfaces to support the hand's regions, including the thenar eminence, palm, thumb, middle finger, ring finger, and index finger, designed to promote an upright and relaxed posture by aligning the hands and forearms naturally, with features like inward and outward curvatures and a specific width extension to accommodate the fingers comfortably.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional hand grip elements are used, then the hand can be held in a fixed position, but the hand and forearm do not achieve natural alignment and posture deteriorates
Solution Approach 1:
The hand grip element features multiple differently shaped surfaces (first shaped surface with curved subregion for ball of hand, second shaped surface for palm, third shaped surface for thumb, fourth shaped surface for middle finger, fifth shaped surface for ring finger, sixth shaped surface for index finger) that provide localized support to specific regions of the hand and fingers, enabling natural alignment while maintaining positional stability
Solution Approach 2:
The hand grip element incorporates multiple curved surfaces including an outwardly curved second shaped surface for palm support, an inwardly curved third shaped surface for thumb support, and outwardly curved fourth and fifth shaped surfaces for finger support, which conform to the natural contours of the hand and promote physiological alignment
2Ease of operation
If the hand grip element has multiple shaped surfaces for finger support, then finger alignment is improved, but the device complexity increases
Solution Approach 1:
The hand grip element combines multiple finger support functions into a single integrated body structure, where the first through sixth shaped surfaces are formed as continuous contours on one piece, providing comprehensive finger alignment without requiring separate components for each finger
3Object-affected harmful factors
If the hand grip element is designed for natural posture alignment, then vitality and performance improve, but the ease of manufacture decreases
Solution Approach 1:
The hand grip element is designed with ergonomic contours that adapt to the natural dynamics of hand positioning during movement, allowing the hand to assume a physiological alignment that promotes vitality and performance while the fixed structure remains manufacturable through conventional molding processes

AI summary
A grip element having an elongate grip body with a first end region and a second end region. The grip body has a first surface near the second end region, with a curved subregion for supporting a subregion of the ball of the human hand, and an outwardly curved second surface supporting a subregion of the palm, and an inwardly curved third surface adjacent to the first surface and supporting the extended thumb, and an outwardly curved fourth surface lying substantially opposite the third surface and supporting the middle finger, adjacent to which fourth surface an outwardly curved fifth surface is provided for supporting the ring finger. The grip body has a sixth surface to support the index finger. The sixth surface, starting from a subregion of the second surface spaced apart from the second end region of the grip body, extends in the direction to the first end region and runs longitudinally along the grip body.
