Multi-Purpose Tool Ratcheted Clamping for Medical Tubes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-functional scissors and tools lack the capability to clamp medical fluid tubes and hold IV hubs effectively, failing to provide incremental pressure through ratchets, and do not integrate features for opening gas cylinder valves, storing tape, or gripping and opening medication bottles.
Innovation Solution
A multi-purpose tool with a first and second shear, each with finger grips, tines, and cutting edges, forming openings for holding articles, and ratchets for clamping, along with additional features like a ruler, oxygen key, bottle opener, screw driver tip, light source, and carabiner for various medical tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing multi-functional scissors are used for cutting and basic holding, then the structure remains simple and easy to use, but the capability to clamp medical fluid tubes and hold IV hubs with incremental pressure is lacking
Solution Approach 1:
The scissor tool is designed to perform multiple functions including cutting, clamping medical tubes, holding IV hubs, opening bottles, and measuring. The tines are shaped to accommodate different objects, and additional features like ratchets, bottle openers, and rulers are integrated into the structure, allowing a single tool to replace multiple separate instruments.
Solution Approach 2:
The scissor is divided into functional segments: cutting edges for shearing, ratcheted surfaces for clamping with incremental pressure, curved inner surfaces for holding IV hubs, and integrated bottle openers. Each segment performs a specific function, allowing the tool to handle diverse medical tasks while maintaining a manageable structure.
2Adaptability or versatility
If existing multi-functional tools include various features like gas cylinder wrenches and pill slicers, then the versatility increases, but the ability to provide incremental pressure for clamping and holding specific medical articles is insufficient
Solution Approach 1:
The ratcheted surfaces on the tines provide periodic engagement as the scissor blades close, creating incremental pressure increases. Each ratchet tooth engages sequentially, allowing controlled, stepwise application of clamping force that can be maintained without continuous user pressure, improving reliability for holding medical articles.
3Adaptability or versatility
If the scissor design includes only basic cutting functionality, then the structure remains simple, but additional capabilities for opening, storing, and measuring are not provided
Solution Approach 1:
Multiple functions are merged into the scissor structure: bottle openers are integrated into the tine surfaces, rulers are attached to the handles, and storage compartments are incorporated into the overall design. This consolidation allows the tool to perform cutting, opening, measuring, and storage functions without requiring separate instruments, though it does increase structural complexity.

AI summary
A multi-purpose tool operated by a user for storing, opening, cutting, clamping and holding of articles is provided. The multi-purpose tool includes a first shear, a second shear movably coupled to the first shear at a pivot point and a ratchet extending from each finger grip. Each shear includes a finger grip, cutting edges, tines and gripping tips. Further, the multi-purpose tool includes ratchet extending from respective finger grips. Each ratchet having a plurality of ratchet teeth defined therein, the ratchets extending towards each other. The first cutting edge and the second cutting edge are adapted for extending around the article in a firm grip by engagement of the ratchets in order to clamp the article between the first cutting edge and the second cutting edge.
