Reusable Deodorant Housing with Interchangeable Cartridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deodorant products contribute significantly to landfill waste due to their plastic components and the need for individual containers, leading to cluttered bathroom spaces and limited user preferences.
Innovation Solution
A reusable deodorant system with interchangeable cartridges that can be easily swapped, allowing multiple users to share or vary deodorant products, made from injection molded plastic or metallic materials with a sliding piston and actuator mechanism for extended or retracted deodorant access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional deodorant products use individual plastic containers, then each user can have their own personalized deodorant, but this leads to significant landfill waste and crowded bathroom spaces
Solution Approach 1:
The deodorant product is divided into two segments: a reusable housing that remains and a replaceable cartridge that is discarded. This segmentation allows the functional part (deodorant) to be replaced while the structural part (housing) is reused, reducing waste while maintaining user variety
Solution Approach 2:
The reusable housing is designed to accept multiple different cartridges with various deodorant formulations, scents, and types. This universal interface allows one housing to serve multiple functions and accommodate different user preferences without needing separate containers for each
2Adaptability or versatility
If conventional deodorant products use individual plastic containers, then each user can have their own personalized deodorant, but this results in crowded medicine cabinets and bathroom drawers
Solution Approach 1:
The universal housing design allows multiple cartridges to be shared across different users through a single container. This eliminates the need for separate containers for each user, significantly reducing the space required in medicine cabinets and bathroom drawers while still supporting diverse deodorant preferences
3Ease of manufacture
If deodorant cartridges are made disposable, then manufacturing and manufacturing simplicity is improved, but this increases landfill waste
Solution Approach 1:
The product is segmented into a permanent housing and a disposable cartridge. The housing is manufactured once and reused, while only the smaller cartridge is disposed of after use. This reduces overall waste compared to disposing of entire containers while maintaining manufacturing simplicity for the cartridge portion
Solution Approach 2:
The system enables recovery and reuse of the housing component while the cartridge is discarded after use. This selective discarding approach minimizes waste by retaining the valuable, expensive housing structure and only disposing of the consumable deodorant cartridge

AI summary
A deodorant system includes a substantially hollow, elongated housing open at either one or two opposing ends. The housing includes a peripheral wall that has at least one slot therethrough, the peripheral wall preferably including a front wall, a rear wall, and two opposing side walls that each includes one of the slots. A piston is slidably retained within the housing and has a cartridge attachment mechanism on a first and optionally a second side thereof. An actuator projects through each slot of the housing and is selectively positionable along the slot to position the piston within the housing. An interchangeable deodorant cartridge has a rigid base with a cooperative cartridge attachment mechanism on a bottom side thereof for attaching to the cartridge attachment mechanism of either one or two sides of the piston. A top side of the rigid base is fixed with a deodorant material.
