Solution Overview

Problem

Existing razor cartridge dispensers are inefficient in retaining, dispensing, and accepting cartridges with both blade and handle connection portions, often requiring large sizes and complex mechanisms, and do not effectively minimize size while ensuring easy access and storage.

Innovation Solution

A razor cartridge dispenser featuring first and second cooperating members joined by a hinge, allowing for a nested configuration that reduces overall height, with compartments designed to accommodate cartridges in a clamshell format, using snap locks or other closure mechanisms to ensure secure storage and easy access, and incorporating ramped walls to prevent blade catchment during removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If traditional separate compartment dispensers are used to store razor cartridges, then each cartridge can be individually retained, but the dispenser requires large size and complex structure to accommodate both blade and handle connection portions

Engineering Contradiction:
Improvenumber of cartridges storedVSAvoiddispenser size
Core Design Contradiction:
Quantity of substanceVSVolume of moving object

Solution Approach 1:

The dispenser utilizes a nested configuration where the handle connection portion of one cartridge is positioned within the space above the blade portion of an adjacent cartridge. This nesting arrangement allows both the blade and handle connection portions to be accommodated in a compact stacked configuration, reducing the overall dispenser volume while maintaining the ability to store multiple cartridges individually.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If dispensers extend walls above handle connection portion to provide coverage, then cartridges are securely retained, but the dispenser size increases and access becomes more difficult

Engineering Contradiction:
Improvecartridge retention securityVSAvoiddispenser height
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The dispenser merges the functions of retention and coverage by using the handle connection portion of one cartridge to provide coverage for the blade portion of the adjacent cartridge. This combining of functions eliminates the need for separate extended walls above each handle connection portion, maintaining secure retention while reducing overall dispenser height.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If complex latch mechanisms are used to engage handle connection portions, then cartridges are securely held, but the dispenser structure becomes more complex and operation more difficult

Engineering Contradiction:
Improvecartridge holding securityVSAvoidlatch mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The dispenser employs a self-retaining mechanism where the positioning of cartridges against the rear wall and the nested arrangement of handle connection portions create automatic retention. The cartridges are held securely by the geometric constraints of the nested configuration and rear wall engagement, eliminating the need for complex active latch mechanisms while maintaining reliable holding security.

Inventive Principle:
Principle #25Self-service
