Razor Handle Cartridge Holder Surrounding Clip for Shock Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional razors with exposed lower housings are prone to damage from external shocks, leading to instability and difficulty in attaching and detaching cartridges.
Innovation Solution
A razor handle assembly with a cartridge holder that surrounds the holder clip, featuring a plunger for elastic support and a latch mechanism for easy attachment and detachment, providing shock protection and improved durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lower housing is exposed to the outside and surrounds the holder, then the structure is simple and easy to manufacture, but the holder clip is vulnerable to external shock and may break
Solution Approach 1:
The invention divides the protective function into two separate components: the lower housing and the cartridge holder. The cartridge holder is designed as a distinct protective structure that surrounds the holder clip, separating the protection function from the lower housing. This segmentation allows the holder clip to be protected without requiring the lower housing to be overly complex.
Solution Approach 2:
The cartridge holder is positioned inside the lower housing structure, creating a nested arrangement where the cartridge holder (inner protective element) is surrounded by the lower housing (outer protective element). This nesting provides multiple layers of protection for the holder clip while maintaining structural simplicity.
2Device complexity
If the holder clip is exposed without surrounding protection, then the structure is simple, but the holder clip breaks easily under external shock
Solution Approach 1:
The cartridge holder provides localized protection specifically around the holder clip area, rather than requiring the entire lower housing to be reinforced. This local quality approach strengthens the vulnerable holder clip region without significantly increasing the complexity of the overall device structure.
3Reliability
If the cartridge holder surrounds the holder clip, then the holder clip is protected from external shock, but the attachment and detachment of cartridges becomes more complex
Solution Approach 1:
The cartridge holder is designed with dynamic characteristics that allow it to pivot relative to the lower housing. This pivoting motion enables the cartridge to be easily attached and detached without requiring complex locking mechanisms, while still providing protective surrounding structure for the holder clip.
4Stability of the object's composition
If the cartridge holder is rigidly fixed, then the structure is stable, but the cartridge cannot be easily attached and detached
Solution Approach 1:
The pivot connection between the cartridge holder and lower housing creates a dynamic joint that provides stability during normal use while allowing controlled movement for cartridge attachment and detachment. This dynamic connection resolves the contradiction between rigidity and operability.

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 design enhances the razor's durability by protecting the holder clip from external shocks and simplifies the attachment and detachment of cartridges, reducing the risk of breakage and making the process more user-friendly.
Implementation Method 1
a plunger which elastically supports the fastening bar and provides a restoring force for restoring the cartridge holder to a home position

AI summary
A razor handle assembly includes a gripping part gripped by a user, and a connecting part provided at one end of the gripping part to fix the cartridge. The connecting part includes a cartridge holder to which the cartridge is detachably coupled, and a holder clip which supports the cartridge holder. The cartridge holder is coupled to surround the outer side of an end portion of the holder clip.
