Razor Handle with Elastic Intermediate Portion for Lateral Pivot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razor handles lack precision and comfort due to their limited movement, primarily allowing only top-to-bottom motion, which hinders a safer and more efficient shaving experience, and do not accommodate lateral movement that could enhance shaving precision and efficiency.
Innovation Solution
A razor handle design featuring a handle body with a front and rear portion, a connecting portion for the cartridge, and a supporting element that allows the front portion to rotate relative to the rear about a first axis, with an intermediate portion made of a more elastic material for additional movement freedom, enabling both pivot and lateral movements for improved shaving precision and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the razor handle comprises a flexible feature allowing top-to-bottom movement, then the shaving comfort is improved, but the precision is insufficient and lateral movement capability is lost
Solution Approach 1:
The razor handle employs a dynamic mechanism allowing the front portion to rotate relative to the rear portion about a first axis (lateral movement) and pivot upwardly and downwardly (vertical movement). This multi-directional dynamic capability enables both precision through lateral adjustment and comfort through vertical movement, resolving the contradiction between precision and comfort.
Solution Approach 2:
The invention adds a lateral movement dimension by allowing rotation about a first axis perpendicular to the longitudinal direction, in addition to the conventional vertical pivot movement. This dimensional expansion provides both precision (via lateral movement) and comfort (via vertical movement), simultaneously addressing both requirements.
2Measurement precision
If the razor handle allows lateral movement for better precision, then the shaving precision is improved, but the structural complexity increases
Solution Approach 1:
The handle body is segmented into a rear portion, an intermediate portion, and a front portion. The intermediate portion includes a first recess and the front portion includes a second recess that receive the elastic element, creating a modular structure. This segmentation allows the lateral movement mechanism to be integrated systematically without excessive complexity.
Solution Approach 2:
An elastic element (flexible feature) is incorporated into the handle body to enable lateral movement of the front portion relative to the rear portion. This elastic component provides the necessary flexibility for precision movement while maintaining a relatively simple overall structure, avoiding the need for complex mechanical linkages.
3Ease of manufacture
If the handle body uses a single rigid material, then the manufacturing is simple, but the movement capability and comfort are limited
Solution Approach 1:
The handle body comprises a first material for the rear and intermediate portions, and a second material for the front portion, where the second material is more elastic than the first. This composite material approach enables the front portion to be more flexible for lateral movement while keeping the rear portion rigid for structural stability, achieving both movement capability and manufacturing feasibility.
Solution Approach 2:
Different portions of the handle body are assigned different material properties: the rear portion uses a rigid first material for structural integrity, while the front portion uses a more elastic second material to enable lateral movement. This local differentiation of material qualities allows the handle to achieve both manufacturing simplicity and operational flexibility.
