Adaptive Gripping Tool with Segmented Nodes for Dexterity Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individuals with limited finger strength, dexterity, or motor functions face challenges in gripping and holding objects, and those without hand use struggle to grasp items with their toes, necessitating a tool that can assist in steadying instruments between digits.
Innovation Solution
A gripping tool system comprising a first instrument grip with a connecting node on a planar side and a channel parallel to it, a second instrument grip with a connecting node on a spherical side, and a wedge with ports to receive these nodes, allowing for versatile and adaptable gripping mechanisms using different shapes and materials like rubber or magnetic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional gripping methods are used by individuals with limited finger strength or dexterity, then basic gripping function is attempted, but the ability to hold and steady instruments is insufficient
Solution Approach 1:
The gripping tool is divided into multiple functional segments: a first grip portion for insertion into one digit, a second grip portion for insertion into another digit, and a connecting structure with channels. This segmentation allows each part to perform a specific function while working together to achieve stable instrument holding.
Solution Approach 2:
The instrument is nested within the gripping tool structure, specifically positioned within the channels formed by the first and second grip portions. The connecting nodes and ports create a nested configuration where the instrument is securely held between the digits through the interconnected grip portions.
2Adaptability or versatility
If a simple gripping structure is used, then device complexity is low, but adaptability to different instruments and user needs is limited
Solution Approach 1:
The gripping tool incorporates universal features including multiple channels in each grip portion that can accommodate different instrument types, connecting nodes that can be configured in various ways, and ports that allow for different connection methods. This multi-functionality enables the same basic structure to adapt to diverse instruments and user requirements.
Solution Approach 2:
The connecting structure between the first and second grip portions includes channels and nodes that can be dynamically configured. The instrument can be positioned at different orientations within the channels, and the connecting nodes can be adjusted to create different geometric configurations, providing dynamic adaptability without requiring multiple specialized devices.
