Solution Overview

Problem

Existing devices for removing small ticks (nymphs) from the skin are risky and ineffective, as they often tear off the tick's body or require risky gripping mechanisms, making it difficult to remove larvae and nymphs without causing injury or stress.

Innovation Solution

A device called the Tick Rotator, featuring a rotatable brush attachment with a centrally recessed hair arrangement, gently rotates the tick to dislodge it without grasping, using a slow and continuous rotation mechanism powered by an electric motor.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If gripping mechanisms (tweezers, loop, card, or pliers) are used to remove ticks, then the tick can be grasped and pulled out, but the tick's body may be torn off or crushed, leaving the biting apparatus impaled in the skin

Engineering Contradiction:

Improveease of tick removalVSAvoidrisk of tick body tearing

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a specialized brush as an intermediary tool between the user and the tick. Instead of directly grasping the tick with tweezers or loop, the brush with its soft bristles gently contacts and rotates the tick, causing it to detach naturally. This intermediary approach eliminates the risk of crushing or tearing the tick's body while still achieving effective removal.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional mechanical grasping system (tweezers, forceps, loop) with a rotational brushing system. Instead of applying direct pulling force through grasping, the device uses gentle rotational motion of soft bristles to stimulate the tick's natural detachment mechanism, substituting a potentially harmful mechanical grasp with a safer rotational contact.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If looping or lever mechanisms are used for tick removal, then adult ticks can be removed, but small ticks (nymphs and larvae) cannot be effectively grasped or removed

Engineering Contradiction:

Improveapplicability to different tick sizesVSAvoiddifficulty in grasping small ticks

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a universal removal mechanism that works across all tick sizes and developmental stages. The rotational brush mechanism does not rely on grasping, which is difficult for small ticks, but instead uses gentle rotation that stimulates natural detachment regardless of tick size. This makes the device equally effective for larvae, nymphs, and adult ticks.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent enables the tick to remove itself through natural detachment mechanisms. By gently rotating the brush against the tick's body, the device stimulates the tick's own physiological response to detach and crawl away. This self-service approach eliminates the need for the user to precisely grasp small, difficult-to-capture ticks, allowing even tiny larvae to be removed effectively.

Inventive Principle:

Principle #25Self-service

3Productivity

If conventional gripping tools are used, then the tick can be pulled out, but the skin may be pinched or subjected to additional stress

Engineering Contradiction:

Improvetick removal efficiencyVSAvoidskin irritation and stress

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the tick's natural attachment mechanism into a benefit for removal. Instead of fighting against the tick's barbed mouthparts through forceful pulling, the gentle rotational brush stimulates the tick's natural detachment behavior. The tick's own physiological response, normally used for maintaining attachment, is leveraged to facilitate easy, painless removal without pinching or stressing the skin.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

4Reliability

If rotation is used for tick removal, then the tick can be gently stimulated to detach, but a precise mechanism for positioning and rotating the tick is needed

Engineering Contradiction:

Improvegentle tick removal without injuryVSAvoidcomplexity of positioning mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a flexible brush head with soft bristles that can conform to the skin surface and gently contact the tick. This flexible contact surface allows for easy positioning without requiring precise mechanical alignment mechanisms. The brush can be simply placed over the tick and rotated, with the flexible bristles adapting to the contours of the skin and tick, eliminating the need for complex positioning systems.

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

The invention relates to a device for removing ticks from the skin of a human being or an animal, comprising: a housing having a handle formed thereon; a rotatable brush attachment; and a receptacle for receiving the brush attachment. The brush attachment has a hair matrix with bristles selected from a group including synthetic hair and natural hair, the hair matrix of the brush attachment having a recess in the center for placing the body of a tick.
