Piezoelectric Tick Removal Instrument
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tick removal devices often fail to ensure complete extraction of the tick without leaving rostral parts in the skin, risk compressing the tick and causing toxic product injection, and may be bulky, require batteries, or pose hygiene risks due to incomplete sealing and potential for tick drop.
Innovation Solution
A compact, battery-free instrument with movable parts forming a closed volume to hold the tick without compression, utilizing a piezoelectric generator to deliver a lethal electric shock for quick and hygienic tick removal, ensuring no rostral parts are left behind and preventing toxic product release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional forceps are used to extract the tick, then the tick can be removed from the skin, but compression is applied to the tick causing toxic product injection
Solution Approach 1:
The patent replaces the conventional mechanical compression-based extraction with an electrical neutralization system. A piezoelectric generator produces high voltage that creates an electric arc to neutralize the tick's nervous system, allowing removal without mechanical compression that would force toxic products into the host.
Solution Approach 2:
The invention changes the physical parameter from mechanical force to electrical voltage. By applying a high voltage electric arc (at least 17,000 volts) to the tick's head, the tick is neutralized electrically rather than mechanically compressed, preventing toxic product injection while ensuring complete rostrum removal.
2Productivity
If conventional forceps are used to extract the tick, then the tick can be removed, but part of the rostrum may remain in the skin
Solution Approach 1:
The patent applies preliminary electrical neutralization to the tick's head before extraction. By delivering the electric arc to the tick's head region first, the rostrum is weakened and detached from the skin, ensuring complete removal during subsequent extraction without leaving fragments behind.
3Reliability
If electrocuting clamps are used to kill the tick, then the tick is neutralized, but the device is bulky and requires a battery power supply
Solution Approach 1:
The patent employs a piezoelectric generator that converts mechanical energy from the user's hand operation directly into electrical energy. The generator contains no battery or external power supply, making the device compact and self-powered through the user's own mechanical input during normal operation.
4Reliability
If electrocuting clamps are used to kill the tick, then the tick is neutralized, but there is risk of electric shock to the animal
Solution Approach 1:
The patent confines the electrical effect to a localized region. The electric arc is generated between two electrodes positioned to contact only the tick's head within the chamber, ensuring the electrical neutralization is applied locally to the tick without affecting the surrounding host animal.
Solution Approach 2:
The patent uses the chamber structure as an intermediary that isolates the electrical effect. The chamber walls and electrode arrangement create a contained environment where the electric arc is restricted to the tick, preventing direct electrical contact with the host animal while still achieving effective neutralization.
5Reliability
If a bell-shaped instrument is used to cover the tick, then the tick can be neutralized with化学物质 or vacuum, but the device is difficult to implement and requires sealing and complex systems
Solution Approach 1:
The patent replaces the complex chemical injection or vacuum systems with a simple piezoelectric generator and electrode arrangement. The chamber serves only as a containment structure, while the piezoelectric mechanism provides a mechanically simple yet effective means of tick neutralization without requiring seals, pumps, or chemical reservoirs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The instrument effectively removes ticks with their rostrum intact, avoiding toxic product dissemination and ensuring hygiene by delivering a lethal electric shock within a closed volume, maintaining the tick's natural detachment without animal risk or product release.
Implementation Method 1
a piezoelectric generator adapted to deliver to the neutralization means an electric voltage causing a lethal electric shock for the tick
Implementation Method 2
The piezoelectric generator supplies two electrical conductors arranged on either side of the passage, the conductors being adapted to produce an electric arc when the organs form the closed volume

AI summary
This instrument, for removing ticks that are fixed to the skin of an animal or of a human being, comprises two parts that are movable relative to one another, each part comprising a member (9, 16) that is designed to define, with the other member (16, 9), a closed volume (18) in which the body and the head (19) of a tick (20) are held without compression. This volume (18) is provided with a neutralizing means connected to a piezoelectric generator designed to deliver, to the neutralizing means, an electrical voltage that produces an electric shock lethal to the tick.
