Refillable Deodorant Dispenser With Spindle-Elevator Cartridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deodorant dispensers are complex mechanical systems with many components, leading to high manufacturing and logistical costs, and are often not redesigned frequently due to plastic packaging concerns, which are environmentally unsustainable.
Innovation Solution
A deodorant dispenser with a rotating body and spindle system that allows for initial filling and refilling through a continuous opening, using a spindle and elevator mechanism for easy refilling with a refill pack, reducing component count and enabling flexible manufacturing options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanical system with multiple components is used for deodorant dispenser, then the dispensing function is reliable, but the manufacturing cost and logistical complexity increase significantly
Solution Approach 1:
The deodorant dispenser is divided into two main segments: a reusable outer housing and a replaceable inner cartridge. The cartridge contains the deodorant mass and essential mechanical components (rotating body, spindle, elevator), while the housing provides structural support and sealing. This segmentation allows the complex mechanical system to be simplified into modular units that can be manufactured separately and assembled, reducing overall manufacturing complexity and cost while maintaining reliable dispensing function.
2Ease of manufacture
If plastic packaging is used for deodorant dispenser, then the manufacturing cost is low and the structure is simple, but the environmental sustainability deteriorates
Solution Approach 1:
The invention implements a refillable system where the outer housing is designed to be reused multiple times, while only the inner cartridge containing the deodorant mass is discarded after use. This approach recovers and reuses the plastic housing component, significantly reducing plastic waste compared to single-use dispensers. The housing can be refilled with new cartridges, extending its lifecycle and reducing the overall environmental impact of plastic packaging.
3Object-affected harmful factors
If the deodorant dispenser is designed to be refillable, then the environmental friendliness improves, but the device complexity increases due to additional refilling mechanisms
Solution Approach 1:
Instead of designing a complex refilling mechanism that fills the dispenser from the outside, the invention inverts the approach by allowing the user to remove the entire inner cartridge and replace it with a new one. The cartridge is designed to be easily removable and replaceable, simplifying the refilling process from a complex mechanical operation to a simple cartridge replacement action. This inversion maintains environmental friendliness through reusability while minimizing added complexity.
4Ease of operation
If a continuous closable opening is provided for filling, then the refilling process is simplified, but the sealing reliability may deteriorate
Solution Approach 1:
The invention uses a removable inner cartridge as an intermediary element between the user and the outer housing. The cartridge contains the deodorant mass and has its own sealing mechanism that can be reliably closed and opened. This intermediary cartridge simplifies the refilling process by allowing users to simply replace the entire sealed cartridge unit, while the sealing reliability is maintained through the cartridge's dedicated sealing design, which is optimized for repeated opening and closing operations.

AI summary
The invention relates to a deodorant dispenser with a container (10) and a rotary body (20) with a first coupling (21), and to a refill pack, filled with a deodorant composition, for such a deodorant dispenser with a refill container, a refill spindle (32) and a refill elevator (40) that is movable up and down on an outer thread of the refill spindle. The refill spindle has a second coupling (31) which, upon insertion of the refill container into the container of the deodorant dispenser, is connectable, with form-fit engagement and for conjoint rotation, to the first coupling of the rotary body of the deodorant dispenser.
