Pivoting Razor Cartridge Coupling With Protected Connector Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor assemblies face issues with the exposure of the coupling portion, leading to potential damage and difficulty in accurately coupling the razor handle and cartridge, along with increased risk of unintended detachment during shaving.
Innovation Solution
A razor assembly design that minimizes the exposure of the coupling portion by pivotally coupling the razor cartridge to the handle, featuring a restoring force providing portion to protect the coupling mechanism and enhance coupling accuracy, with a recognizable direction indicator and a lower resting angle for improved shaving performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the coupling portion is exposed for easy coupling, then the coupling operation becomes easier, but the coupling portion becomes vulnerable to external impact and damage
Solution Approach 1:
The coupling portion is nested within the housing structure, specifically positioned in a coupling cavity that provides protection from external impact while maintaining accessibility for coupling operations. The housing acts as a protective shell that encloses the vulnerable coupling portion.
Solution Approach 2:
A protective cover or housing structure serves as an intermediary element between the coupling portion and external environment. This intermediary structure allows coupling operations to proceed while shielding the coupling portion from harmful external impacts.
2Ease of operation
If the coupling mechanism is simplified for easy coupling, then the coupling operation becomes easier, but the risk of unintended detachment increases
Solution Approach 1:
The coupling mechanism is divided into distinct functional segments: a coupling portion for easy engagement, a locking mechanism for securing the connection, and a restoring force providing portion for maintaining stability. This segmentation allows each component to perform its specific function optimally.
Solution Approach 2:
A restoring force providing portion (such as a spring mechanism) is incorporated to preemptively counteract forces that might cause unintended detachment. This preliminary anti-action ensures that the coupling remains stable during shaving operations without complicating the coupling process.
3Duration of action of stationary object
If the coupling portion is protected from exposure, then durability is improved, but the user may have difficulty recognizing the coupling direction
Solution Approach 1:
Visual indicators such as color-coded markings or contrasting colors are applied to the housing and coupling portion to indicate the correct coupling direction. These visual cues remain visible even when the coupling portion is protected within the housing structure.
Solution Approach 2:
Asymmetric features or markings are incorporated into the housing design that clearly indicate the correct orientation for coupling. The asymmetric design makes it visually obvious which direction the coupling portion should face, eliminating confusion while maintaining protection.

AI summary
A razor assembly may include at least one blade formed with a cutting edge. The razor assembly may also include a blade housing accommodating the at least one blade in a longitudinal direction, and a connector disposed on one side of the blade housing. The razor assembly may further include a razor handle connected to the blade housing so that the blade housing can pivot, the razor handle including a coupling portion configured to couple with the connector. The razor assembly may further include a restoring force providing portion configured to provide a restoring force against pivoting of the blade housing, the restoring force providing portion being configured to cover at least a portion of the coupling portion from above the coupling portion.
