Tourniquet Windlass Device with Integrated Writing Instrument
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of readily available windlass devices for tourniquets in situations where immediate bleeding control is necessary, as most individuals do not typically carry such devices due to their specialized nature.
Innovation Solution
A dual-function device that serves as an effective windlass for tourniquets and a writing instrument, featuring a housing with knurling and a clip to secure a constricting band, allowing for efficient blood flow restriction, and can be made from materials like stainless steel or anodized aluminum, increasing the likelihood of it being carried by individuals such as EMTs or campers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specialized windlass device is carried for tourniquet use, then bleeding control capability is improved, but device complexity and portability are worsened
Solution Approach 1:
The patent combines a windlass device with a writing instrument (pen or pencil) into a single integrated unit. The housing contains both the writing element and the windlass mechanism, allowing the device to function as both a writing tool and a tourniquet windlass. This merging eliminates the need to carry separate specialized equipment while maintaining full bleeding control capability.
Solution Approach 2:
The device is designed with multiple functions: it can be used as a writing instrument for documentation purposes and as a windlass for applying tourniquets in emergency bleeding situations. The housing, clip, and knurled surface are designed to serve both functions effectively, making the device universally useful in various contexts rather than specialized for a single purpose.
2Adaptability or versatility
If a dual-function device is created, then portability and carrying likelihood are improved, but device complexity is worsened
Solution Approach 1:
The windlass mechanism is integrated into the housing of a writing instrument, combining two functional elements into one compact unit. The clip is attached to the housing to secure both the constricting band and the writing device itself, creating a unified structure that eliminates the need for separate carrying of multiple devices.
3Loss of time
If immediate bleeding control is prioritized, then response time is improved, but availability of windlass device is worsened
Solution Approach 1:
The device is designed to be carried in advance by individuals who may need it for emergency bleeding control. By integrating the windlass function into a commonly carried item like a writing instrument, the necessary equipment is already in place and readily accessible when needed, eliminating delays associated with searching for or retrieving specialized equipment.
