Interlocking Razor Cartridge Case for Integrated Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing manufacturing of razor cartridges involves separate production of protective cases and dispensers, leading to increased plastic usage and costs, while environmental regulations aim to reduce plastic consumption.
Innovation Solution
A razor cartridge protective case design that integrates both protective and dispenser functions, allowing interconnection of multiple cases to minimize plastic use and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If protective cases and dispensers are produced separately, then each component can be optimized for its specific function, but the overall manufacturing cost increases and plastic material usage increases
Solution Approach 1:
The patent combines the protective case and dispenser into a single integrated cartridge assembly. The protective case serves dual functions: protecting the razor blades during transport and storage, and acting as the dispenser housing that holds multiple cartridges. This merging eliminates the need for separate protective case and dispenser components, reducing manufacturing cost and plastic usage while maintaining protective and dispensing functions.
Solution Approach 2:
The protective case is designed to perform multiple functions: it protects the razor cartridges from damage, serves as the outer housing for the dispenser, and provides the structural framework for the entire product. This multi-functionality reduces the total number of components needed and simplifies the overall structure while maintaining all necessary functions.
2Ease of manufacture
If separate protective cases and dispensers are used, then each can be independently manufactured, but the total plastic material usage increases
Solution Approach 1:
By merging the protective case and dispenser into a single integrated structure, the patent eliminates duplicate plastic components. The protective case becomes the dispenser housing, removing the need for separate plastic parts for each function and thereby reducing total plastic material usage.
Solution Approach 2:
The integrated design allows the entire cartridge assembly (protective case + dispenser + cartridges) to be used as a single disposable unit. After use, the entire assembly can be discarded together, eliminating the need for separate disposal of multiple plastic components and reducing overall plastic waste.
3Reliability
If multiple separate protective cases are used to hold cartridges, then each cartridge is individually protected, but the overall device complexity and cost increase
Solution Approach 1:
The patent merges multiple protection functions into a single protective case structure. Instead of using separate protective cases for each cartridge, the integrated design provides a unified protective housing that contains and protects multiple cartridges simultaneously, reducing the number of components while maintaining protection effectiveness.
Solution Approach 2:
The dispenser cartridges are nested within the protective case housing. The protective case serves as the outer container that holds multiple inner cartridges, creating a nested structure where smaller components are placed within a larger protective structure. This nesting approach provides individual protection for each cartridge while using a single outer protective case.

AI summary
Proposed is at least one razor cartridge protective case each including a receiving space configured to receive at least a portion of a razor cartridge extending in a longitudinal direction. Each cartridge protective case may include a front wall disposed at a front of the receiving space. Each case may also include a rear wall disposed at a rear of the receiving space and configured to be opposed to the front wall in a lateral direction. One of the front wall and the rear wall may include one or more first coupling portions. The other one of the front wall and the rear wall may include one or more second coupling portions. The first coupling portion may be detachably coupled to the second coupling portion of an another razor cartridge protective case along a height direction.
