Thread-Holding Chuck for Hygienic Epilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current threading tools and devices lack adequate protection against contamination from the technician's saliva and skin cells during epilation, particularly in heightened hygiene awareness periods.
Innovation Solution
A device with a thread-holding chuck and attachment system that provides a third point of control for thread tensioning, replacing the mouth anchor with a user-worn element such as a neck strap, headband, or face shield, ensuring contamination prevention while maintaining tactile feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the technician uses mouth as anchor point for thread tensioning, then control over thread tension is improved, but contamination risk from saliva and skin cells increases
Solution Approach 1:
The patent introduces a mouthguard device as an intermediary between the technician's mouth and the thread. The mouthguard includes a threaded insert that receives the epilation thread, allowing the technician to maintain mouth-based tensioning control while preventing direct contact between saliva and the thread. This intermediary structure resolves the contradiction by enabling control function while blocking contamination pathways.
Solution Approach 2:
The invention extracts the contaminating element (mouth/saliva) from direct contact with the thread by introducing a protective barrier. The mouthguard separates the functional aspect (tension control through threading) from the harmful aspect (saliva exposure), allowing the beneficial control mechanism to remain while removing the contamination risk.
2Measurement precision
If hands are used for thread manipulation, then dexterity and precision are improved, but hygiene protection is compromised during pandemic conditions
Solution Approach 1:
The mouthguard acts as a mediator that allows the technician to maintain hand-based thread manipulation while protecting against contamination. By providing a mouth-based anchor point that doesn't require direct hand-to-mouth contact, the device enables precise control through the thread while maintaining hygiene barriers during pandemic conditions.
