Lice Removal Device Comb Vacuum Airflow Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lice removal devices often fail to capture lice effectively, allowing them to escape and potentially reinfest hair, as they either do not trap or kill the lice during the removal process.
Innovation Solution
A lice removal device equipped with a comb unit and a vacuum system that includes arcuate portions for air sealing, a rotatable blade unit, a latch member for angular adjustment, a filter with adhesive material for capturing lice, and a gate valve to ensure airflow and prevent lice escape, all integrated with a fan unit for efficient lice capture and disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard comb device is used to remove lice, then the comb can physically remove lice from hair, but the lice are not captured and can escape to reinfest the hair
Solution Approach 1:
The patent combines a comb unit with a vacuum system into an integrated device. The comb teeth are positioned to engage hair while the vacuum source simultaneously draws air and captured lice into a containment chamber, merging two functions (combing and vacuuming) into one device to ensure lice are captured immediately upon removal
Solution Approach 2:
The patent introduces an intermediary containment chamber that receives lice from the comb teeth via air flow. This intermediate structure prevents direct escape of lice while maintaining the separate functions of combing and containment, solving the reliability issue without overly complicating the device
2Reliability
If a vacuum arrangement is added to the comb to capture lice, then lice capture effectiveness improves, but the device complexity increases
Solution Approach 1:
The device is segmented into distinct functional modules: a comb unit with teeth for mechanical removal, a vacuum source for air flow generation, and a containment chamber for lice storage. This segmentation allows each component to perform its specific function efficiently while maintaining overall device manageability
Solution Approach 2:
The patent uses pneumatic principles by employing a vacuum source to create air flow that carries lice from the comb teeth into the containment chamber. This pneumatic transport mechanism provides reliable lice capture without requiring complex mechanical trapping structures
3Reliability
If the comb is formed as an attachment to a vacuum hose, then lice can be drawn into a containment chamber, but the structure becomes more complex and harder to operate
Solution Approach 1:
The comb unit serves multiple functions: it mechanically engages and removes lice from hair through its teeth, and simultaneously acts as an air intake structure for the vacuum system. The containment chamber both receives lice and serves as a visible indicator of capture effectiveness, providing multi-functionality that simplifies operation
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 device efficiently captures and traps lice, preventing reinfestation by ensuring air flow directs lice into a filter where they are either trapped or killed, enhancing the reliability of lice removal compared to standard comb devices.
Implementation Method 1
a fan unit to draw air into the comb housing and through the main housing
Implementation Method 2
the first and second side members also include respective first and second arcuate portions on sides thereof opposite the teeth, the arcuate portions being provided to seal across the elongate opening in the comb housing such that air is directed to enter the comb unit via the elongate opening
Implementation Method 3
a filter is received in the first aperture of the main housing to capture lice as air is drawn in from the comb housing and through the main housing
Implementation Method 4
a gate valve is provided adjacent the first end of the main housing such that air drawn into the main housing causes the gate valve to open and the gate valve closes when not air is flowing to prevent escape of lice
