Solution Overview

Problem

Existing methods for removing nose and ear hairs, such as tweezers, rotary nose hair clippers, waxing, razors, and scissors, are often painful, time-consuming, and costly, with limitations in efficiency and self-administration.

Innovation Solution

A mechanical hair puller with a plunger, housing, and spring mechanism that allows for quick and painless removal of unwanted hairs by extending the spring to grab and pull out multiple hairs simultaneously, operated by the user's thumb and fingers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tweezers are used to remove hairs, then hair removal is achieved, but the process is time-consuming and painful

Engineering Contradiction:

Improvehair removal efficiencyVSAvoidprocessing time

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent combines multiple hair removal functions into a single device that can remove multiple hairs simultaneously. The housing structure incorporates both a cutting mechanism and a plucking mechanism, allowing the user to address multiple hairs in one operation rather than treating each hair individually with traditional tweezers.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The device segments the hair removal process into distinct functional zones within the housing - a cutting portion for trimming hairs and a plucking portion with protrusions for removing multiple hairs simultaneously. This segmentation allows each component to specialize in a specific aspect of hair removal, improving overall efficiency.

Inventive Principle:

Principle #1Segmentation

2Productivity

If rotary nose hair clippers are used, then hair removal is achieved, but the root is not removed and frequent maintenance is needed

Engineering Contradiction:

Improvehair removal completenessVSAvoidmaintenance frequency

Core Design Contradiction:

ProductivityVSDuration of action of stationary object

Solution Approach 1:

The device merges both cutting and plucking functions into one tool. The cutting portion trims excess hair length while the plucking portion with internal protrusions extracts hairs by the root, providing complete hair removal in a single operation rather than requiring separate treatments.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The housing is segmented into functional zones where the cutting portion handles surface-level trimming and the plucking portion with its protruding elements targets root-level removal. This segmentation ensures both shallow and deep hair removal needs are addressed simultaneously.

Inventive Principle:

Principle #1Segmentation

3Productivity

If waxing is used to remove multiple hairs, then efficiency is improved, but the process is painful and requires professional assistance

Engineering Contradiction:

Improvehair removal efficiencyVSAvoidpain level

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device is designed for self-application, allowing users to comfortably remove their own nose and ear hairs without requiring professional assistance. The ergonomic housing and strategically positioned protrusions enable the user to access hard-to-reach areas independently, eliminating the need for costly professional waxing services.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The device applies a moderate, controlled plucking action through its protrusions rather than the forceful waxing method. This partial action approach removes multiple hairs simultaneously like waxing but with significantly reduced pain and without requiring professional intervention.

Inventive Principle:

Principle #16Partial or excessive action

4Productivity

If razors or scissors are used, then hair removal is achieved, but there is risk of nicks and cuts

Engineering Contradiction:

Improvehair removal efficiencyVSAvoidrisk of injury

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The device uses the housing structure itself as an intermediary guide that directs the cutting and plucking actions. The housing confines and controls the movement of the cutting blade and plucking protrusions, preventing them from accidentally contacting the skin and causing nicks or cuts while still effectively removing hairs.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

This invention relates to the removal of hair including the root, from the nostrils and the ear canals, as well as for some various facial hairs. It is a mechanical device using a tension coil spring attached to a plunger and housing assembly to extend the spring, thereby creating multiple openings between the individual coils of the spring so as to allow multiple hairs to enter the openings, after which the plunger is released and the coils of the spring retract, grabbing the hairs with adequate friction to pull them out. This device is operated by the thumb and two fingers and can remove any unwanted hair, particularly nose and ear hair, within a couple of minutes with almost no pain.
