Lice Comb System with Nested Detangling and Heating Tines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lice combs are difficult to use in tangled hair, causing pain and do not effectively kill lice, as they only remove lice and eggs without a mechanism for eradication.
Innovation Solution
A dual-comb system with an inner row of closely spaced lice-removing tines and an outer row of detangling tines, where the inner comb can be heated to kill lice, and the outer comb's design reduces pressure on the scalp by using rounded tips and a snap-fit mechanism for easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fine-tooth lice comb is used to remove lice, then lice removal effectiveness is improved, but the comb becomes difficult to run through tangled hair causing pain
Solution Approach 1:
The comb is divided into two distinct functional sections: an outer comb with widely spaced detangling tines and an inner comb with closely spaced lice-removing tines. This segmentation allows each section to perform its specialized function independently, enabling the comb to both detangle hair and remove lice effectively without compromising ease of operation or lice removal effectiveness
Solution Approach 2:
The inner comb is nested within the outer comb structure, with the inner comb's handle receiving into a slot in the outer comb handle. This nested configuration allows the closely spaced lice-removing tines to be protected and positioned within the broader detangling tine structure, enabling sequential action where detangling occurs first followed by lice removal
2Reliability
If sharp metal tines are used to remove lice, then lice removal effectiveness is improved, but pain is caused when pressed into the scalp
Solution Approach 1:
Different tine properties are applied to different functional zones: the outer comb tines have rounded tips for gentle detangling, while the inner comb tines have sharp points for effective lice removal. This local differentiation ensures that scalp contact occurs only with gentle rounded surfaces, eliminating pain while preserving lice removal effectiveness
Solution Approach 2:
The outer comb with rounded detangling tines acts as a cushioning layer that contacts the scalp first during combing. This beforehand cushioning prevents direct contact between sharp lice-removing tines and the scalp, eliminating pain before it can occur while maintaining lice removal effectiveness
3Device complexity
If a single comb design is used, then device complexity is reduced, but the ability to both detangle hair and remove lice effectively is compromised
Solution Approach 1:
Two separate comb functions (detangling and lice removal) are merged into a single integrated comb system. The outer comb with widely spaced tines handles detangling, while the inner comb with closely spaced tines handles lice removal. Both functions operate within one device, providing dual functionality without requiring separate combs
Solution Approach 2:
The comb system achieves multi-functionality by incorporating both detangling and lice-removing capabilities in a single device. The outer comb provides detangling function while the nested inner comb provides lice removal function, making the comb universally applicable for both hair preparation and lice eradication
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 dual-comb system effectively detangles hair while removing lice with reduced discomfort and ensures lice eradication by heating the inner tines, addressing the limitations of existing lice combs.
Implementation Method 1
the inner comb may be heated to a temperature sufficient to kill the lice

AI summary
In one embodiment, A lice removal comb system includes an inner comb and an outer comb. The inner comb may include a row of lice-removing tines and a handle. The outer comb may include a first row of hair-detangling tines, a second row of hair-detangling tines, a handle, and a slot formed in the outer comb, between the first and second rows of hair-detangling tines. The outer comb may be configured to removably receive the inner comb such that the row of lice-removing tines is disposed between the first and the second rows of hair-detangling tines.
