Hybrid Epilator Angular Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid epilator devices lack convenience and flexibility in adjusting epilation efficiency and pain level during hair removal, as they are optimized for a fixed angle and do not effectively manage both plucking and shaving in a single stroke.
Innovation Solution
A hybrid epilator device with a razor blade and an epilation cylinder, featuring a manually operable adjustment mechanism that allows the angular position of the clamping elements to be adjusted, enabling variable epilation efficiency and pain level by moving the razor blade and epilation cylinder relative to the skin surface, ensuring complete hair removal in a single stroke.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the epilation cylinder is optimized for a fixed angle, then the epilation efficiency is maximized, but the device lacks flexibility to adjust pain level and adapt to different skin surfaces
Solution Approach 1:
The mounting structure is made movable relative to the epilation cylinder, allowing the razor blade to be repositioned angularly. This dynamic configuration enables the device to adjust the angle at which the clamping elements contact the skin, thereby varying the epilation efficiency and pain level while maintaining a relatively simple overall device structure.
2Productivity
If the device performs both plucking and shaving in a single stroke, then complete hair removal is achieved, but the control over the ratio of plucked to shaved hairs is limited
Solution Approach 1:
The angular position of the razor blade relative to the epilation cylinder is changed as a controllable parameter. By adjusting this angle, users can control the proportion of hairs that are plucked versus shaved, thereby controlling the pain level while maintaining complete hair removal efficiency in a single stroke.
3Reliability
If the clamping elements are in tight contact with the skin, then epilation efficiency is high, but the device cannot adapt to uneven skin surfaces
Solution Approach 1:
The mounting structure allowing angular adjustment of the razor blade enables the device to adapt its contact angle to uneven skin surfaces. This dynamic adjustment maintains reliable epilation efficiency by ensuring proper engagement of the clamping elements while accommodating variations in skin topography.

AI summary
The present invention is concerned with a hybrid epilator device that comprises at least a razor blade (80) having a sharp edge for cutting hairs, an epilation cylinder (11) comprising at least a pair of clamping elements (12) that during operation are actuated by an actuation system (121, 122, 119, 120) between an open position and a closed position so that hairs can feed into the gap between the pair of clamping elements (12) in the open position and are gripped and plucked out from the skin surface (90) when the pair of clamping elements (12) is in the closed position, and a manually operable adjustment mechanism (110; 19) that has a least a first adjustment and a second adjustment such that in the first adjustment and the second adjustment the skin surface (90) can be simultaneously contacted by the sharp edge of the razor blade (80) and an circumferential area of the epilation cylinder (11), while the angular position (a; a'; a") at which the closed position of the pair of clamping elements (12) is assumed with respect to the skin surface (90) during regular operation is different in the first and second adjustment. This allows switching at least between two different epilation efficiencies of the epilation cylinder (11).
