Dual-Guide Razor Shaving Head for Long and Short Beards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razors struggle with providing a good shaving effect on long and messy beards, requiring a cumbersome process of combing and trimming before shaving.
Innovation Solution
A razor design featuring comb teeth and guide slots of varying depths and lengths on the shaving head, allowing for efficient combing and guiding of different beard types, with adjustable cutting edges for optimal shaving results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional razors are used for shaving, then the shaving effect is good on short beards, but the operation process becomes cumbersome when beards are long and messy
Solution Approach 1:
The shaving head is segmented into multiple functional zones: a first guide slot for long and messy beards, and a second guide slot for shorter beards. Each zone has comb teeth with specific depth characteristics that segment the shaving process into stages appropriate for different beard lengths, eliminating the need for separate combs and trimmers.
Solution Approach 2:
The shaving head integrates multiple functions into a single device: it combines the combing function for long beards, the guiding function for medium beards, and the shaving function for short beards all in one component. The blade is positioned to work with both guide slots, making the razor universally applicable to all beard types without requiring multiple separate tools.
2Manufacturing precision
If comb and trim are performed before shaving, then the shaving effect improves for long beards, but the operation process becomes more complex
Solution Approach 1:
The patent merges the combing, guiding, and shaving functions into a single integrated shaving head. The first guide slot with deeper comb teeth combines the combing action for long beards directly with the shaving blade, eliminating the need for separate combing and trimming steps while maintaining precise shaving results.
Solution Approach 2:
The first guide slot performs preliminary combing and guiding of long and messy beards before they reach the shaving blade. This preliminary action prepares the beard hair by organizing it into the guide slot, making the subsequent shaving action more precise and efficient without requiring separate pre-treatment steps.
3Adaptability or versatility
If a single guide slot depth is used, then the structure is simple, but it cannot effectively handle different beard lengths
Solution Approach 1:
Different regions of the shaving head have different guide slot depths tailored to specific beard length requirements. The first guide slot has deeper comb teeth for long and messy beards, while the second guide slot has shallower comb teeth for shorter beards. This local differentiation of guide slot depths allows effective handling of various beard lengths while keeping each individual slot's structure simple.

AI summary
Provided are a shaving head of a razor with a cover body, a base and a blade. The cover body is provided with a cover plate arranged opposite to the base and partially covering the base, a blade slot is formed between the cover plate and the base. The base has at least a first side and a second side exposing outside the blade slot, in which the first side is provided with at least two first comb teeth, with a first guide slot formed between the two adjacent first comb teeth; the second side is provided with at least two second comb teeth, with a second guide slot formed between the two adjacent second comb teeth; the first comb teeth is longer than the second comb teeth. The blade slot receives the blade which has a first cutting edge facing the first side and a second cutting edge facing the second side. The first cutting edge and the second cutting edge are both exposed outside the blade slot but do not extend beyond the first side or the second side of the base. The technical solution provided by the present application is that through cooperation of the first guide slot and the second guide slot, various forms of beards can be combed and guided for shaving cleanly by the cutting edges, while the razor and the shaving head have simple structure and is convenient to operate and strongly versatile.
