Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product dispensers are not superior in function, costly to manufacture, and difficult to recycle.
Innovation Solution
A dispensing container design featuring a product tube with internal threads and a ram tube with a product support platform, allowing easy dispensing by twisting, and constructed from materials like aluminum for cost-effectiveness and recyclability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional dispensing container design is used, then manufacturing cost is reduced, but manufacturing efficiency and recyclability are worsened
Solution Approach 1:
The dispensing container is divided into separate functional components: a product tube with internal threads, a ram tube with external threads, and a product support platform. This segmentation allows each component to be manufactured independently using optimized processes and facilitates easier recycling of individual parts.
Solution Approach 2:
The ram tube is inserted into the product tube, and the product support platform is mounted on the distal end of the ram tube. This nested arrangement creates a compact structure while maintaining simple manufacturing processes for each individual component.
2Ease of manufacture
If traditional dispensing container design is used, then design simplicity is maintained, but recyclability is worsened
Solution Approach 1:
By dividing the container into separable components with standardized threaded connections, each part can be easily removed and recycled independently. The product tube, ram tube, and platform can be separated for material recovery without requiring complex disassembly procedures.
Solution Approach 2:
The threaded connection design allows for easy separation of components at the end of product life, enabling efficient recovery and recycling of materials such as aluminum or plastic tubes and platforms.
3Adaptability or versatility
If innovative dispensing mechanism is added, then functionality is improved, but manufacturing cost is worsened
Solution Approach 1:
The threaded connection between the ram tube and product tube enables the consumer to easily assemble and disassemble the dispenser themselves. This self-service assembly eliminates the need for complex manufacturing and assembly equipment, reducing manufacturing costs while providing innovative dispensing functionality through simple rotational movement.
Solution Approach 2:
The traditional complex mechanical dispensing mechanisms are replaced with a simple threaded connection system that uses basic rotational mechanics. This substitution maintains effective dispensing functionality while dramatically simplifying the manufacturing process and reducing costs.

AI summary
A dispensing container has a product tube that has a top opening and a bottom opening. An internal thread is formed on an inner surface of the product tube. A ram tube has a threaded exterior surface that extends from a proximal end and a distal end. A product support platform is mounted on the distal end of the ram tube. The threaded exterior surface of the ram tube threadedly engages the internal thread of the product tube, such that rotation of the ram tube advances the product support platform and dispenses cosmetic product from the top opening of the product tube.
