Hunting Knife Integrated Tick Extraction Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tick removal methods, such as tweezers, often leave the tick's mouth in the skin, risking infection and fail to accommodate ticks of varying sizes, while also being inconvenient for outdoor use.
Innovation Solution
A multifunctional hunting or survival knife with a tick extraction device housed in the handle, featuring interchangeable slots for different tick sizes, allowing safe removal without compression and easy storage and retrieval.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional tweezers are used for tick removal, then the device is simple and easy to carry, but the tick's rostrum often remains embedded in the skin and the tick body may be compressed
Solution Approach 1:
The tick removal device is segmented into multiple functional components: a V-shaped slot for gripping the tick body, a curved edge for severing the rostrum, and a notched tip for extracting the rostrum. This segmentation allows each component to perform its specific function independently, ensuring complete removal without requiring complex user technique.
Solution Approach 2:
The device introduces an intermediary structure (the V-shaped slot with curved edge and notched tip) that mediates between the user's gripping action and the tick's body. This intermediary structure guides the user's actions and ensures proper mechanical interaction with the tick, eliminating the need for specialized technique.
2Measurement precision
If tweezers with small opening are used to grip small ticks, then the gripping precision is improved, but the tick body is compressed increasing infection risk
Solution Approach 1:
The V-shaped slot provides a localized gripping area with specific geometry (angle and depth) that matches the tick's body shape. This local quality ensures accurate positioning of the tick within the slot without requiring the entire tweezer opening to be small, thus avoiding compression while maintaining grip precision.
3Adaptability or versatility
If a single-slot tick remover is used, then the device structure is simple, but it cannot accommodate ticks of different sizes
Solution Approach 1:
The device incorporates multiple V-shaped slots with different dimensions within a single tool head, allowing one device to serve multiple functions for different tick sizes. This multi-functionality approach maintains relative simplicity while achieving adaptability across various tick species and sizes.
4Adaptability or versatility
If tick removal device is carried separately outdoors, then the functionality is available, but the risk of losing the device increases
Solution Approach 1:
The tick removal device is merged with a knife by integrating it into the knife handle, creating a single unified tool. This combination ensures that the tick removal functionality is always available when the knife is present, eliminating the risk of losing a separate tick remover while outdoors.
