Closed-Loop Razor Cartridge Clip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strip-shaped razor cartridge clips are cumbersome to fix, prone to damage, and can easily release, posing safety risks during shaving due to their ease of bending and susceptibility to external forces.
Innovation Solution
A razor cartridge with closed-loop clips that are fixed to the blade housing through a process involving deformation, eliminating the need for bending or inserting legs into holes, and providing a secure attachment that prevents separation of the shaving blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional strip-shaped clip is used, then the clip can be easily processed by bending or cutting, but the clip is easy to be arbitrarily opened by users and easily damaged by external forces
Solution Approach 1:
The patent inverts the conventional open-ended strip shape into a closed-loop configuration. The clip is formed as a continuous loop with no ends, transforming the structure from something that can be easily opened to something that cannot be arbitrarily separated. This inversion maintains manufacturability through forming processes while dramatically improving reliability by preventing user-induced opening and enhancing resistance to external forces.
2Ease of manufacture
If the conventional strip-shaped clip is used, then the clip can be fixed to the blade housing, but the fixing process is cumbersome requiring bending of legs or insertion into through-holes
Solution Approach 1:
The patent extracts and eliminates the complex leg structures and through-holes from the conventional design. The closed-loop clip achieves fixation through its continuous loop configuration that can be deformed and expanded to engage with the blade housing, removing the need for separate bending operations or insertion steps. This simplifies the overall fixing process while maintaining secure attachment capability.
Solution Approach 2:
The closed-loop clip utilizes dynamic deformation capability to transition from a compressed state during assembly to an expanded state during operation. The clip can be elastically deformed to fit through opening in the blade housing and then naturally expands to its original shape, creating a secure snap-fit connection without requiring complex manual manipulation or additional fastening steps.
3Ease of operation
If the conventional strip-shaped clip is used, then the clip can hold the shaving blade, but the shaving blade is susceptible to be separated from the blade housing
Solution Approach 1:
The patent inverts the open-ended strip structure into a closed-loop configuration that completely encircles the blade housing. This continuous loop structure provides 360-degree engagement around the housing, preventing any separation points that would allow the blade to detach. The closed configuration transforms the holding mechanism from a linear constraint to a circumferential constraint, dramatically improving attachment security.
