Flexible Grasping Collar for Wet Bottle and Syringe Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cylindrical objects such as bottles and hypodermic syringes are prone to slipping and tilting due to their geometry, leading to instability, especially when wet, which poses hazards during medical procedures and handling of liquids, and existing solutions do not provide adequate non-slip solutions for secure gripping and positioning.
Innovation Solution
A multi-functional grasping device featuring a flexible collar with strategically designed slits and cavities for finger reception, providing secure grip and positioning, and a bottle support system with pliable ribs that can deform to grip bottles at various angles, preventing rolling and tilting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a smooth cylindrical surface is used for bottle supports, then the device structure is simple, but the gripping reliability deteriorates causing slippage
Solution Approach 1:
The bottle support features localized gripping elements (ribs, flanges, or textured surfaces) at specific contact points rather than uniform surface treatment. These localized features provide high-friction grip zones while maintaining overall structural simplicity, resolving the contradiction between simple design and reliable gripping.
Solution Approach 2:
The bottle support employs asymmetric geometries such as non-circular cross-sections, uneven rib distributions, or biased flange positions that create stable resting positions and prevent rolling. This asymmetric design provides reliable gripping and stability without requiring complex mechanisms, balancing structural simplicity with functional reliability.
2Ease of manufacture
If a cylindrical geometry is used for bottles, then the manufacturing is easy, but the stability deteriorates causing rolling and tilting
Solution Approach 1:
The bottle incorporates asymmetric features such as non-circular base geometries, uneven shoulder profiles, or integrated stabilization ribs that create stable resting positions. These asymmetric modifications maintain ease of manufacturing through simple molding or forming processes while effectively preventing rolling and tilting during handling and storage.
3Ease of operation
If wet hands are used for gripping, then the ease of operation is maintained, but the gripping reliability deteriorates due to reduced friction
Solution Approach 1:
The grasping device incorporates localized high-friction surfaces, textured grip zones, or compliant gripping elements at contact points. These localized features maintain high gripping reliability even when hands are wet, while requiring minimal gripping force and allowing easy operation without dry hands.
Solution Approach 2:
The bottle support utilizes flexible or compliant materials that can deform to conform to the bottle surface and maintain secure contact. This flexibility ensures reliable gripping through friction and adhesion even when hands are wet, while requiring minimal gripping force for easy operation.
