Straight Razor With Disposable Blade Head And Fast Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional straight razors pose hygiene concerns and are time-consuming to disinfect or replace, while disposable options lack the elegance and sturdiness preferred by professionals.
Innovation Solution
A straight razor design featuring a permanent handle and shank with a disposable razor blade head, incorporating a fast release mechanism for easy single-handed replacement, adjustable weight, and a variety of blade heads for versatility, made from degradable materials for enhanced hygiene and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional straight razor with a permanent blade is used, then elegance and sturdiness are maintained, but hygiene concerns arise and time-consuming disinfection or replacement is required
Solution Approach 1:
The razor is divided into separate components: a permanent handle and a disposable blade holder assembly. This segmentation allows the blade holder to be replaced independently, eliminating the need to disinfect the entire razor and enabling quick blade changes while maintaining the permanent handle's elegance and sturdiness
Solution Approach 2:
The blade holder is designed as a disposable component that is discarded after use, eliminating hygiene concerns associated with permanent blades. This disposable approach ensures hygiene without requiring time-consuming disinfection processes, as each new blade holder is pre-packaged and sterile
2Reliability
If a disposable straight razor is used, then hygiene is improved, but elegance and sturdiness are compromised
Solution Approach 1:
The razor system is segmented into a permanent handle (providing sturdiness and elegance) and a disposable blade holder (providing hygiene). This allows each component to be optimized for its specific function: the handle for durability and the blade holder for卫生
Solution Approach 2:
The blade holder assembly combines multiple materials and components (blade, housing, connector elements) to create a composite structure that provides both hygiene through disposability and sufficient sturdiness for effective shaving, while the permanent handle uses high-quality materials for long-term durability
3Adaptability or versatility
If a blade replacement mechanism is added, then hygiene and versatility are improved, but device complexity increases
Solution Approach 1:
The connector incorporates a spring-loaded locking mechanism that dynamically adapts during blade insertion and removal. The spring provides automatic engagement and disengagement forces, enabling easy blade replacement without complex manual operations while maintaining secure attachment during use
Solution Approach 2:
The spring-loaded locking mechanism is self-actuating, requiring minimal user input for blade replacement. The spring automatically engages the locking elements during insertion and releases them during removal, reducing the need for complex user-operated mechanisms while ensuring reliable blade attachment

AI summary
A straight razor (10) comprising a permanent handle (12) and a shank (14) that are interconnected through a pivotal fixating element (24) and a disposable razor blade head (16) that includes a razor blade (62) embedded to a housing (60). The disposable razor blade head (16) is reversibly connected to the shank (14) and may be released by a fast release mechanism (30, 32, 34) after each use and be replaced by a new razor blade head.
