Rotary Spindle Deodorant Dispenser for Modular Refill Packs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current deodorant dispensers have complex mechanical systems with many components, leading to high production and logistical costs, and are often not redesigned for years, while also being made of plastic, which faces environmental scrutiny.
Innovation Solution
A deodorant dispenser with a rotary body and spindle system that allows for easy filling and refilling with a solid deodorant mass, using a rotary body and spindle system for ascending or descending movement, and a refill pack design that can be easily integrated, reducing component complexity and enabling multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex mechanical system with multiple components is used in deodorant dispensers, then the dispensing function is reliable, but the production cost and device complexity increase
Solution Approach 1:
The deodorant dispenser is divided into distinct functional modules: a reusable dispenser body and replaceable refill packs. Each refill pack contains its own deodorant mass and application mechanism, allowing the complex dispensing function to be segmented into simpler, interchangeable units. This reduces the complexity of the main dispenser body while maintaining reliable dispensing through the modular refill packs.
Solution Approach 2:
The dispenser body is designed with universal features that can accommodate different refill pack types. The rotary body and coupling mechanism serve multiple functions: they secure the refill pack, enable rotation for deodorant application, and provide a interface for refilling. This multi-functionality reduces the need for additional specialized components.
2Ease of manufacture
If deodorant dispensers are made of plastic, then manufacturing is easy and cost-effective, but environmental sustainability deteriorates
Solution Approach 1:
The refill packs are designed to be replaceable and potentially recyclable. After the deodorant mass is consumed, the refill pack can be removed from the dispenser body. The system enables separation of the deodorant mass from the packaging, facilitating recycling or proper disposal of different materials, thereby reducing environmental impact while maintaining ease of manufacture through standardized plastic components.
3Adaptability or versatility
If deodorant dispensers are redesigned frequently, then product adaptability improves, but production costs and logistical complexity increase
Solution Approach 1:
By segmenting the dispenser into a permanent body and replaceable refill packs, the system allows adaptability to be achieved through refill pack variations rather than redesigning the entire dispenser. Different refill pack types can be introduced without changing the main dispenser body, reducing production costs and logistical complexity while maintaining product adaptability.
Solution Approach 2:
The dispenser body incorporates universal coupling mechanisms and rotary interfaces that work with multiple refill pack designs. This universality allows the same dispenser body to accommodate various deodorant formulations, packaging types, and refill mechanisms, enabling product adaptability without requiring costly redesigns of the entire system.
4Adaptability or versatility
If a rotary body with coupling mechanism is used, then refillability is enabled, but device complexity increases
Solution Approach 1:
The coupling mechanism is merged with the rotary body structure, where the coupling elements are integrated into the rotary interface itself. This combination eliminates the need for separate coupling devices and simplifies the mechanical system while maintaining the refill capability. The rotary motion simultaneously secures and positions the refill pack.

AI summary
A deodorant dispenser includes a container and a rotary body with a first coupling. A refill pack filled with a deodorant composition for the deodorant dispenser includes a refill container, a refill spindle, and a refill elevator that is movable up and down on an outer thread of the refill spindle. The refill spindle has a second coupling 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.
