Attachment Comb Sloped Clamping Plane Adjustable Hair Length
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hair cutting devices and combs are often configured for a fixed hair cutting length, requiring complex mechanisms for adjustable settings, which are not straightforward to adjust.
Innovation Solution
A releasable attachment comb with a support frame, clamping elements, and comb teeth, featuring a sloped clamping plane and locating notches that allow the cutting element to be slid to different positions for varying hair lengths, facilitated by displaceable clamping elements and a pinch and snap mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed length attachment comb is used, then the device structure is simple, but the adaptability for different hair lengths is limited
Solution Approach 1:
The attachment comb employs a dynamic clamping mechanism where the clamping elements can be displaced between a first position (for securing the cutting element) and a second position (for releasing it). This dynamic positioning allows the comb to adapt to different cutting lengths by enabling the user to slide the cutting element to different locations along the comb teeth while maintaining a relatively simple overall structure.
Solution Approach 2:
The comb structure is segmented into multiple functional components: comb teeth with varying lengths, clamping elements with locating notches, and a support frame. The locating notches are segmented along the comb to define discrete positioning locations, allowing the cutting element to be secured at different heights. This segmentation provides multiple cutting length options without requiring a completely different comb for each length.
2Adaptability or versatility
If multiple fixed length combs are provided, then all hair lengths can be covered, but the device complexity and number of parts increases
Solution Approach 1:
The attachment comb is designed as a universal multi-functional device that can accommodate cutting elements for various hair lengths. By incorporating comb teeth of different lengths and a displacement mechanism, a single comb can perform the function of multiple fixed-length combs. The user can adjust the cutting length by displacing the clamping elements and repositioning the cutting element along the comb, eliminating the need to carry or store multiple separate combs.
3Manufacturing precision
If a complex adjustment mechanism is used, then precise hair length control is achieved, but the ease of operation is reduced
Solution Approach 1:
The clamping elements are designed to be manually displaceable by the user without requiring additional tools or complex mechanisms. The locating notches automatically engage with corresponding features on the cutting element to maintain precise positioning once the desired length is selected. This self-service design allows the user to independently adjust and secure the cutting length by simply displacing the clamping elements and repositioning the cutting element, achieving both precision and ease of operation.

AI summary
A releasable attachment comb coupled to a cutting head of a hair cutting device providing an adjustable hair cutting length. The attachment comb comprising clamping elements disposed at opposite ends of a support bar a set of comb teeth arrayed along the support bar between the clamping elements. Locating/retaining notches provided on opposing inner faces of the clamping element defining a series of clamping positions to receive and lock a cutting element of the cutting head. The locating notches arranged on the opposed inner faces of the clamping elements defining between them a sloped clamping plane for the cutting element. The notches defining clamping positions at multiple points along the sloped plane. The clamping elements adapted to be displaceable away from one another so as to displace the respective notches of each clamping element away from one another, thereby permitting release and advancement of a received cutting element from one clamping position to another.
