Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving heads do not effectively adapt to uneven skin surfaces, leading to inefficiencies in hair removal and potential discomfort.
Innovation Solution
A shaving head with movable cutting members and an actuator member that retracts cutting edges in response to pressure, utilizing a pressure sensor element and cantilever elements to adjust exposure based on skin contours.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cutting members are kept at fixed exposure level, then device structure is simple, but shaving performance on uneven skin surfaces deteriorates
Solution Approach 1:
The cutting members are designed to be movable rather than fixed, allowing them to dynamically adjust their exposure level in response to skin surface variations. The actuator member enables this dynamic adjustment by retracting or extending cutting members based on detected skin contours, resolving the contradiction between maintaining simple structure and achieving adaptability to uneven surfaces.
Solution Approach 2:
The actuator member functions as a feedback mechanism that detects skin surface conditions and automatically adjusts cutting member exposure accordingly. This closed-loop system allows the shaving head to adapt to uneven skin surfaces without requiring complex manual adjustment mechanisms, thereby improving adaptability while controlling structural complexity.
2Object-affected harmful factors
If cutting members are retracted to avoid skin irritation, then comfort is improved, but hair removal efficiency deteriorates
Solution Approach 1:
The cutting members dynamically adjust their exposure level based on real-time skin surface conditions detected by the actuator member. When encountering skin irregularities or areas prone to irritation, the cutting members are automatically retracted. On flat skin surfaces, they extend to full exposure for optimal hair removal efficiency. This dynamic adjustment resolves the contradiction by allowing the system to optimize both comfort and efficiency根据不同 skin conditions.

AI summary
The present disclosure pertains to a shaving head comprising a frame and one or more cutting members arranged between a leading longitudinal side and a trailing longitudinal side of the frame. One or more of the cutting members are movable in a direction orthogonal to a shaving plane. The shaving head comprises an actuator member, which is configured to retract one or more cutting members relative to the shaving plane in response to a pressure exerted on the actuator member.
