Shaving Head Multi-Purpose Retainer for Cleaning and Performance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shaving devices face a challenge in achieving high shaving performance while maintaining ease of cleaning, as complex designs required for high performance complicate the cleaning process of their cutting units.
Innovation Solution
The Multi-Purpose Retainer Principle is implemented in the shaving head, which includes a ring-like skin-supporting tilting member, an external cutting member with an opening structure, an internal cutting member, and a retainer that provides locking, secondary tilting, and anti-floating functions, allowing for easy assembly and disassembly for cleaning while maintaining high shaving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shaving head design is made more complex to achieve high shaving performance, then the shaving performance is improved, but the cleaning complexity increases
Solution Approach 1:
The cutting unit is divided into separable components including the external cutting member, internal cutting member, and retainer that can be easily detached from each other. This segmentation allows each component to be individually cleaned without disassembling the entire shaving head, thereby maintaining high shaving performance while simplifying the cleaning process.
Solution Approach 2:
The retainer is designed as a separate extractable component that can be removed from the cutting unit. This extraction capability allows users to take out the retainer and clean the cutting members independently, reducing cleaning complexity while preserving the complex multi-component structure needed for high shaving performance.
2Reliability
If the cutting unit structure is made more complex to improve shaving performance, then the shaving performance is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The cutting unit incorporates movable and adjustable components including the tilting member that can pivot and the retainer that can be easily attached and detached. These dynamic features allow the complex cutting unit to be quickly disassembled for cleaning and reassembled for use, maintaining high shaving performance while improving ease of cleaning.
Solution Approach 2:
The retainer includes built-in locking and unlocking mechanisms that allow users to easily disassemble and reassemble the cutting unit without requiring tools or complex procedures. This self-service design enables users to maintain the complex cutting unit structure needed for high performance while keeping cleaning simple and accessible.
3Reliability
If multiple components are added to the cutting unit to achieve high shaving performance, then the shaving performance is improved, but the number of parts increases making cleaning more difficult
Solution Approach 1:
The retainer is designed as a multi-functional component that simultaneously provides locking, positioning, and easy release functions. This universality allows the complex cutting unit with multiple parts to be managed through a single versatile component, maintaining high shaving performance while reducing the practical complexity of cleaning by consolidating multiple functions into one easily manipulated part.

AI summary
The invention relates to a shaving head comprising at least one cutting unit (7, 7A, 7B). The cutting unit comprises a ring-like skin-supporting tilting member, being tillable relative to a shaving head main body (4, 8) about a first tilting axis, an external cutting member, an internal cutting member, and a retainer. According to the invention, the retainer is a multi-purpose retainer in that it provides simultaneously a locking function, a secondary tilting function and an anti-floating function. By virtue of the multi-purpose retainer, the shaving device delivers a high shaving performance and is also easy to clean.
