Adjustable Facial Shaving Guide with Lateral Turnbuckle Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hair trimming devices for facial hair are not adjustable to individual beard patterns, making it difficult to trim without obstruction and are often complex and expensive to manufacture.
Innovation Solution
An adjustable facial shaving guide with a mouthpiece, a rigid base, and guide members that can be laterally adjusted using turnbuckles, allowing for precise trimming of the beard without obstruction, and is simple and cost-effective to produce.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed template is used for facial hair trimming, then the device structure is simple, but it cannot be adjusted to individual beard patterns
Solution Approach 1:
The patent applies the dynamics principle by making the guide members adjustable rather than fixed. The guide members can be moved laterally along the base and secured at different positions using turnbuckles, allowing the device to adapt to various beard patterns and facial contours while maintaining a relatively simple overall structure.
2Ease of operation
If a rigid fixed guide is used, then the manufacturing cost is low, but the user's view in the mirror is blocked
Solution Approach 1:
The guide members are designed to be laterally adjustable along the base, allowing users to position them optimally for trimming while maintaining an unobstructed view in the mirror. This dynamic positioning capability eliminates the need for large, fixed guides that would block the user's view.
3Adaptability or versatility
If multiple guide members are added for adjustability, then individual beard adaptation improves, but manufacturing complexity increases
Solution Approach 1:
The device is segmented into a base and multiple independent guide members. Each guide member can be independently adjusted and secured, allowing for customized trimming patterns. This segmentation enables adaptability without requiring a completely complex integrated structure.
Solution Approach 2:
The guide members incorporate lateral adjustability with turnbuckle mechanisms, allowing each member to be independently positioned and secured. This dynamic adjustment capability provides beard pattern adaptability while using simple, manufacturable components.

AI summary
A guide for trimming the beard of a person with a razor is disclosed. A mouth piece has a proximal end adapted for gripping with a mouth of the person, and a distal end. A rigid base is fixed at a proximal side thereof to the distal end of the mouth piece. The base further comprises a distal side, at least one peripheral edge connecting the proximal side, and in one embodiment at least one guide adjustment means. A pair of guide members each have a continuous outer side, an inner side, and at least one peripheral edge connecting the outer and inner sides. Each guide member further includes at least one adjustment post engaged with the at least one guide adjustment means of the base. The guide adjustment means is adapted to adjust the lateral position of each guide member with respect to the base. With the mouth piece held by the mouth of the person, the at least one guide adjustment means of the base may be actuated to adjust the lateral position of each guide member to a desired location on a face of the person. The person is then able to trim the beard with the razor only on the areas of the face not shielded by the guide.
