Pocket Knife Integrated Tick Remover Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional pocket knives lack an integrated tick remover that is compatible with their design, making it difficult to efficiently remove ticks while outdoors.
Innovation Solution
A multifunctional pocket knife design incorporating a flat tick-removal instrument that pivots about link pins, featuring a planar element with a 'V'-shaped cleft for tick extraction, a return spring for immobilization, and optional features like elastically deformable material and a gripping member for easy deployment and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a tick remover is integrated into a pocket knife, then tick removal functionality is added, but device complexity increases
Solution Approach 1:
The tick remover is designed as a multi-functional element that can be integrated into the existing pocket knife structure. The planar element serves both as a structural component of the knife and as a functional tick removal tool when deployed, allowing one object to perform multiple functions without significantly increasing overall complexity
Solution Approach 2:
The tick remover is nested within the pocket knife handle structure, utilizing the existing stowage space and link pin mechanism. When not in use, the tick remover is concealed within the handle; when needed, it pivots outward for use, then returns to its nested position automatically via spring mechanism
2Adaptability or versatility
If a tick remover is added to the pocket knife, then the number of tools increases, but the handle size increases
Solution Approach 1:
The tick remover utilizes the longitudinal dimension of the handle by extending along the longitudinal axis when deployed. The planar element is positioned to extend from the stowage space outward, using the length of the handle rather than increasing its width or thickness, thus adding functionality without significantly increasing the handle's cross-sectional dimensions
3Adaptability or versatility
If a tick remover is integrated into the pocket knife, then tick removal capability is provided, but ease of operation is reduced
Solution Approach 1:
The tick remover incorporates a spring mechanism that automatically returns the planar element to its stowage position within the handle after use. This self-returning feature reduces the operational steps required by the user, as they only need to deploy the tool outward for use, and it automatically retracts afterward without requiring manual manipulation to reset

AI summary
The multifunctional pocket knife (1) is composed of a handle (2) formed by two joined-together flanks (3, 3′) that provide at least one stowage space (4) for tools that each pivot about link pins (5, 5′) arranged at each end of the handle (2). It is characterized in that it comprises a planar tick-removal instrument (6) that pivots about one of said link pins (5, 5′) and that extends along the longitudinal axis of the pocket knife.Tick-removal instrument (6) designed to be incorporated into a multifunctional pocket knife (1).
