Rotating Head Unit for Irregular Surface Shaving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hair removers are limited in their ability to remove body hair from areas with irregularities due to a fixed posture, leading to incomplete shaving and are not easily portable or downsized for convenience.
Innovation Solution
A hair remover with a rotating head unit that can change its direction relative to the main unit, allowing for adjustable cutting angles and a compact design, featuring a drive unit with a motor and transmission system that enables the head unit to rotate and adjust its position to avoid interference with body contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head unit is fixed in a single posture (parallel or perpendicular to extension direction), then the structure is simple, but the hair remover cannot adapt to irregular body surfaces and causes interference with body contours
Solution Approach 1:
The head unit is made rotatable relative to the main unit through a rotating mechanical section, allowing it to dynamically change its orientation angle. This enables the head unit to adapt to irregular body surfaces by adjusting its posture, while the rotation mechanism maintains reasonable structural complexity through compact design
2Productivity
If the head unit protrudes from the main unit to provide cutting function, then the cutting performance is improved, but the device size increases and portability is reduced
Solution Approach 1:
The head unit is designed to be retractable into the main unit when not in use, similar to a nested doll structure. The rotating mechanical section allows the head unit to be positioned within the outer periphery of the main unit, reducing the overall device volume and improving portability while maintaining cutting performance when deployed
3Productivity
If the head unit is positioned to protrude for effective hair cutting, then the cutting efficiency is improved, but the device becomes less portable and harder to carry
Solution Approach 1:
The head unit can dynamically switch between protruding position (for cutting) and retracted position (for portability). The rotating mechanical section enables this dynamic repositioning, allowing the user to extend the head unit only when needed for hair cutting, thereby maintaining cutting efficiency while improving ease of carrying and storage

AI summary
A hair remover including: a main unit having a gripper, a head unit having a blade for removing body hair, and a drive unit for driving the blade. The main unit is provided, in one end thereof, with an extension portion that supports the head unit. The extension portion extends in one direction, referred to as an extending direction, from the one end on the main unit. The hair remover is configured to switch between a first state where a longitudinal direction of the head unit is parallel to the extension direction and a second state where the longitudinal direction of the head unit is perpendicular to the extension direction. The hair remover is configured so that an outer periphery of the head unit is located so as to be flush with or is located within an outer periphery of said the main unit when viewed from the extension direction.
