Variable-Angle Razor Head for Precise Edge Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shaving razors lack precision due to obstructive guards, leading to uneven and imprecise shaving lines, which is a challenge for skilled artisans and individuals seeking intricate hair shaping.
Innovation Solution
A dual-sided shaving razor with a modular head that allows adjustable blade angles through deformation by a support structure, enhancing visibility and precision by applying pressure to the blade's edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If guards are used in safety razors to protect the user, then safety is improved, but precision and visibility of the blade edge deteriorate
Solution Approach 1:
The head is divided into two separate sides: a first side with a first guard and a second side with a second guard. Each guard is independently configured with different characteristics (thickness, curvature, opening size) to optimize for different shaving needs while maintaining safety on both sides.
Solution Approach 2:
Each guard is designed with specific local properties: the first guard has a first thickness and first curvature optimized for one type of shave, while the second guard has a second thickness and second curvature optimized for another type. This allows each side to have tailored characteristics for precision while maintaining protective function.
2Reliability
If thick guards are used to protect the user, then safety is improved, but visibility and precision of cutting edges deteriorate
Solution Approach 1:
The protective function is segmented into two guards with different optical properties. The first guard has a first opening configured to expose the first cutting edge, while the second guard has a second opening configured to expose the second cutting edge, allowing each side to optimize visibility for its intended use.
Solution Approach 2:
Each guard is designed with local optical characteristics: the first guard has a first opening size and shape optimized for visibility of the first cutting edge, while the second guard has a second opening size and shape optimized for visibility of the second cutting edge, enabling precision work on both sides.
3Device complexity
If a single blade angle is used, then device simplicity is maintained, but adaptability to different shaving needs deteriorates
Solution Approach 1:
The blade is divided into two cutting edges with different angular orientations. The first cutting edge is oriented at a first angle relative to the reference plane, while the second cutting edge is oriented at a second angle relative to the reference plane, allowing the user to select the appropriate edge for different shaving needs without changing the basic razor structure.
Solution Approach 2:
The two cutting edges are deliberately designed with asymmetric angular orientations relative to the reference plane. This asymmetry provides different shaving characteristics (e.g., one edge for closer shaves, another for longer hair) while maintaining a symmetric dual-sided head structure for overall simplicity.
4Manufacturing precision
If guards with large openings are used to improve visibility, then precision is improved, but user protection deteriorates
Solution Approach 1:
The protective function is segmented into two guards with different opening characteristics. The first guard has a first opening configured to expose the first cutting edge while providing protection, and the second guard has a second opening configured to expose the second cutting edge while providing protection, allowing each side to optimize the balance between visibility and safety.
Solution Approach 2:
Each guard is designed with local protective properties: the first guard has a first thickness and first opening size optimized for the first cutting edge's usage, while the second guard has a second thickness and second opening size optimized for the second cutting edge's usage, enabling each side to achieve appropriate protection levels for its specific function.

Function Achieved in This Case
Enables precise and efficient shaving maneuvers, allowing users to create intricate patterns and enhance their grooming experience.
Implementation Method 1
coupling the gripping member to the head causes the support structure to compress against the blade deforming the first cutting edge and the second cutting edge of the blade to substantially match the first angular orientation and the second angular orientation of the head respectively

AI summary
A shaving implement having a head, a blade, a support structure, and a gripping member. The blade having a first and second cutting edge deformed by a compressive force between the head and a support structure. The angle of deformation being dependent on the angular orientation of a first and second side of the head, where both angles of deformation are distinct from each other. The compression of the blade being dependent on a compression by a user who acts upon the gripping member to move the support structure towards the head until the blade is substantially clamped between the head and the support structure. When not in use, the shaving implement may be positioned upright on a base of the gripping member.
