Solution Overview

Problem

Existing tick removal devices are either expensive, difficult to use in hard-to-reach areas, prone to accidental injury, or inconvenient for daily carry due to size and design limitations, and lack effective protection mechanisms.

Innovation Solution

A tick removal device designed as an elongate stick with a beveled front end and a conically narrowing receiving slot, featuring a movable shell for protection and easy handling, produced through injection molding, which minimizes the risk of injury and allows safe storage, and optionally includes a light source and pressureless medicinally active liquid cartridge.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If tick removal devices are made small and portable for daily carry, then ease of operation is improved, but safety and protection mechanisms are compromised

Engineering Contradiction:
ImproveportabilityVSAvoidaccidental injury risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The device incorporates a movable protective cap that can be dynamically positioned to cover or expose the working tip. The cap is retained by a spring-loaded mechanism that automatically secures it during storage but allows easy removal during use, providing dynamic protection against accidental injury while maintaining portability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device is divided into distinct functional segments: a protective cap, a spring mechanism, a handle, and a working tip with extraction elements. This segmentation allows the protective cap to be independently positioned and removed, enabling safe storage when not in use while maintaining ease of operation when deployed.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If spring elements are included for automatic cap retention, then protection mechanism is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveprotection mechanismVSAvoidspring element inclusion
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The spring mechanism is designed to be pre-compressed during assembly and to automatically retain the protective cap without requiring additional power sources or complex control systems. The spring provides continuous elastic force to maintain cap retention, enabling the device to self-regulate its protection state based on whether the cap is in place.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the device is made compact for pocket storage, then ease of operation is improved, but the effectiveness in hard-to-reach areas deteriorates

Engineering Contradiction:
Improvestorage convenienceVSAvoidaccessibility to hard-to-reach areas
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The device incorporates an extendable shaft mechanism that allows the working tip to be projected forward from the compact handle body. This dimensional extension enables the tip to reach into hard-to-access areas such as ears or dense fur, while the collapsed configuration maintains compactness for pocket storage.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Adaptability or versatility

If multiple functional elements are integrated into one device, then device versatility is improved, but manufacturing cost and complexity increase

Engineering Contradiction:
Improvemulti-functionalityVSAvoidintegrated components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The device merges multiple tick removal mechanisms (pincer elements, loop elements, and extraction elements) into a single integrated tip structure. These elements are positioned at different locations on the tip and can be selectively engaged with the tick body, providing multi-functional capability while maintaining a unified compact design that simplifies manufacturing.

Inventive Principle:
Principle #5Merging (Combining)
