Razor Connector Angled Locking Element Universal Handle Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor designs lack flexibility to accommodate different handle designs and materials, limiting customization options and ergonomics, and often require specific connection mechanisms that prevent compatibility with various razor handles.
Innovation Solution
A connector system featuring a retracting shaft with a locking element that expands in an angled direction, allowing for a secure and adaptable connection between a blade assembly and a razor handle of any shape, feature, or material, using a friction-locking connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a blade assembly is removably attached to a razor handle using existing connection mechanisms (snap-fit, threaded, or magnetic), then the blade assembly can be replaced when worn out, but the blade assembly becomes incompatible with razor handles of different models
Solution Approach 1:
The connector is designed with a standardized interface that can be universally applied across different razor handle models. The connector body with its specific geometric features (cylindrical shape, longitudinal groove, engagement protrusions) creates a universal connection system that works with multiple handle designs, allowing the same blade assembly to be compatible with various razor models while maintaining secure attachment and easy replaceability
2Reliability
If razor designs are optimized for specific handle shapes and materials, then the connection mechanism can be secure and reliable, but the design lacks flexibility to accommodate different handle designs and materials
Solution Approach 1:
The connection system is divided into separate functional components: the connector body, the retracting shaft, and the locking element. This segmentation allows each component to be optimized independently - the connector body provides universal compatibility, the retracting shaft enables controlled engagement, and the locking element ensures secure connection. This modular approach maintains connection reliability while adapting to different handle designs and materials
3Strength
If a connector uses a locking mechanism to securely attach the blade assembly, then the connection is robust, but the connector structure becomes more complex
Solution Approach 1:
The locking element is designed to automatically engage and lock when the connector is assembled with the razor handle. The retracting shaft, when actuated, causes the locking element to expand in an angled direction that naturally interfaces with the handle's cavity, creating a self-locking mechanism. This self-service approach provides robust connection strength while minimizing the need for additional complex locking components or assembly steps
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The connector system enables easy replacement of blade assemblies and provides compatibility with various handle designs, enhancing user convenience, flexibility, and customization options while ensuring a secure and robust connection.
Implementation Method 1
The connector is designed to couple the blade assembly to the razor handle by a non-positively locking connection, more specifically by a friction-locking connection
