Razor Cartridge Connector Visual Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing razor cartridges and handles often have incompatible connection structures, making it difficult for users to correctly mount the razor handle, which can lead to improper attachment, damage during separation, and safety issues during shaving.
Innovation Solution
The razor cartridge incorporates an indicator within the connecting groove that provides visual mounting information, including the entry position and direction of the razor handle, allowing users to easily align and attach the handle correctly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If no visual indicator is provided in the connecting groove, then the device structure remains simple, but users cannot easily recognize the correct mounting position and direction of the razor handle
Solution Approach 1:
The patent applies visual indicators (such as colored marks, patterns, or symbols) within the connecting groove to indicate the correct mounting position and direction of the razor handle. This allows users to easily recognize the proper orientation through visual cues without adding complex mechanical structures, thereby improving ease of operation while maintaining structural simplicity.
2Loss of information
If the connector structure is made more complex to provide mounting guidance, then mounting information can be provided, but the device structure becomes more complex
Solution Approach 1:
Instead of creating complex mechanical guidance structures, the patent uses visual indicators that copy or represent mounting information in a simplified form. The indicators (such as colored zones, arrows, or symbols) convey the necessary mounting guidance without requiring additional mechanical complexity in the connector structure.
3Loss of information
If visual indicators are added to the connecting groove, then mounting information becomes visible, but the connector structure becomes more complex
Solution Approach 1:
The patent incorporates visual indicators such as colored marks, patterns, or symbols directly into the connecting groove structure. These indicators provide clear mounting information (position and direction) without requiring significant structural modifications, thereby minimizing the increase in device complexity while effectively communicating mounting guidance to users.

AI summary
A razor assembly is proposed. The razor assembly may include a razor handle, at least one razor blade having a cutting edge formed thereon. The razor assembly may also include a blade housing including a razor blade mounting portion in which the razor blade is accommodated in a longitudinal direction, an upper surface on which the razor blade is exposed, and a lower surface opposite to the upper surface. The razor assembly may further include a connector disposed adjacent to the lower surface and including a connecting groove into which the razor handle enters. An indicator providing mounting information of the razor handle may be provided within the connecting groove.
