Cutting Attachment Comb Surface for Stable Skin Sliding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting device attachments do not adequately improve the sliding properties of the skin contact surface, leading to inconsistent hair cutting lengths.
Innovation Solution
The attachment features a comb part with a skin contact surface and a pair of sandwiching walls, including an uneven part to enhance sliding properties, allowing for a more stable and uniform cutting process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the skin contact surface is made smooth for comfortable sliding, then the sliding comfort is improved, but the attachment may unintentionally move during use
Solution Approach 1:
The skin contact surface is designed with different local properties: most of the surface remains smooth for comfort, while specific localized regions contain uneven parts that provide anti-slip functionality. This allows the surface to simultaneously deliver sliding comfort and prevent unintentional movement.
Solution Approach 2:
The uneven parts act as intermediary elements between the smooth skin contact surface and the attachment body, providing a mechanical interlocking mechanism that prevents slippage while maintaining overall surface smoothness for comfort.
2Reliability
If the skin contact surface is made uneven to prevent slippage, then the attachment stability is improved, but the sliding comfort deteriorates
Solution Approach 1:
Rather than making the entire skin contact surface uneven, the invention introduces uneven parts only in specific localized regions. This ensures that the majority of the surface remains smooth for comfort, while the localized uneven portions provide sufficient anti-slip functionality.
3Ease of manufacture
If the attachment structure is simplified for easy manufacturing, then the manufacturing cost is reduced, but the ability to ensure consistent cutting length is compromised
Solution Approach 1:
The uneven parts are designed as simple localized features that can be easily integrated into the attachment manufacturing process without requiring complex tools or techniques, while still providing the functional benefit of preventing slippage and ensuring consistent cutting length.

AI summary
An attachment for a cutting device further improves the sliding properties of the skin contact surface on the skin. Such a cutting device to which the attachment is also included in the present disclosure. The attachment according to the present disclosure includes a base, a comb part with which the base is provided and which protrudes in second directions intersecting first directions, and a pair of sandwiching walls with which the base is provided and which sandwich the cutting device from both sides in third directions intersecting the first directions and the second directions. Here, the comb part includes a facing surface positioned on one side in the first directions to face a blade part and a skin contact surface positioned on the other side in the first directions to come into contact with skin. The skin contact surface is provided with an uneven part.
