Solution Overview

Problem

Existing solutions for storing safety razors with shaving blade cartridges do not ensure immediate readiness for use while maintaining sanitary and dry conditions, and often require manual handling that risks accidental cuts.

Innovation Solution

A spring-biased container design that retains a razor blade cartridge with an attached handle, partially within and partially extending out, allowing for immediate use by overcoming the spring bias, and includes an antiseptic or desiccant pill container to maintain sanitary and dry conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the razor blade cartridge is entirely retained within the container, then the blade remains protected and sanitary, but the razor is not ready for immediate use

Engineering Contradiction:

Improvesanitary condition of bladeVSAvoidreadiness for use

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The container is divided into two functional zones: a sealed interior chamber for storing the razor blade cartridge in sanitary conditions, and an exterior handling area where the handle is accessible. The container lid acts as a segmented barrier that separates the sterile interior from the external environment during opening/closing operations.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The razor handle is pre-positioned with its distal end extending through the container wall into the exterior handling area. This preliminary positioning allows the razor to transition from stored to ready state simply by opening the lid, without requiring additional manual manipulation inside the container.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If the handle is entirely within the container, then the blade remains sealed and protected, but the razor cannot be immediately used

Engineering Contradiction:

Improveprotection from contaminationVSAvoidimmediate usability

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The handle extends through the container wall in a direction perpendicular to the lid opening motion. This spatial arrangement in another dimension allows simultaneous achievement of sealed storage (when lid is closed) and immediate usability (when lid is open), as the handle is already positioned for grasping outside the container.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Reliability

If manual handling is required to remove the razor, then the razor can be stored securely, but accidental cuts may occur

Engineering Contradiction:

Improvesecure storageVSAvoidrisk of accidental cuts

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The container lid serves as an intermediary mechanism that mediates between the sealed storage state and the usage state. Opening the lid exposes the razor handle in a controlled manner without requiring fingers to reach inside the container, thus eliminating the risk of accidental cuts while maintaining secure storage when closed.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Reliability

If the container is spring-biased closed, then the razor remains sealed, but force is required to open it

Engineering Contradiction:

Improvesealed conditionVSAvoidforce to open container

Core Design Contradiction:

ReliabilityVSForce

Solution Approach 1:

The spring mechanism provides dynamic sealing pressure that automatically maintains the closed sealed state. The spring force is continuously applied to keep the lid closed, ensuring the razor remains protected, while allowing controlled opening when sufficient force is applied to overcome the spring bias.

Inventive Principle:

Principle #15Dynamics

AI summary

A container that retains a razor blade cartridge within the container with a handle attached to the razor blade cartridge with the handle partially within the container and partially extending out of the container. The container is a spring biased container to keep it closed and it is necessary to provide a force that overcomes the spring force and open the container so that the handle and attached razor blade cartridge can be removed from the container which then snaps shut due to the closing spring force, the safety razor with razor blade cartridge and handle are ready for immediate use. Antiseptic and/or desiccant can be retained in the container.
