Mini Pump Nozzle Anti-Sliding Element Dual Material Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mini pump nozzle devices and handheld portions require complex bi-color injection molding processes, increasing manufacturing costs and complexity due to the need for different hardness materials and simultaneous thread formation, which complicates the production process.
Innovation Solution
A mini pump design featuring a handheld portion and anti-sliding element made from resins with different hardnesses, where the anti-sliding element is softer and manufactured via injection molding, eliminating the need for bi-color injection molding machines and simplifying the production process by allowing sequential fabrication and secure attachment to the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If bi-color injection molding is used to manufacture the handheld portion and anti-sliding element with different hardnesses, then the comfort and anti-sliding performance are improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent divides the handheld portion and anti-sliding element into separate components manufactured independently through injection molding, then assembles them together. This segmentation allows each part to be made from optimal single-material resins with different hardnesses without requiring complex bi-color molding equipment, thus maintaining comfort and anti-sliding performance while simplifying the manufacturing process.
Solution Approach 2:
The patent combines the handheld portion and anti-sliding element into a single integrated assembly that functions as one unit during use. The anti-sliding element is disposed on the head and partially received in the groove of the handheld portion, creating a unified structure that provides both comfort and grip functionality while being manufactured through separate but coordinated injection molding processes.
2Adaptability or versatility
If bi-color injection molding machine with rotary drive is used for simultaneous molding and thread formation, then multiple functions are achieved, but extra power is required and manufacturing cost increases
Solution Approach 1:
The patent separates the molding process from the thread formation process. The handheld portion and anti-sliding element are first molded independently using standard injection molding machines, then threads are formed separately on the molded parts. This segmentation eliminates the need for a complex bi-color injection molding machine with rotary drive that combines multiple functions, thereby reducing power consumption and manufacturing cost.
Solution Approach 2:
The patent performs the injection molding of the handheld portion and anti-sliding element as preliminary actions before thread formation. By completing the molding process first and then adding threads through a separate operation, the patent avoids the need for simultaneous multi-function operations during molding, reducing the power requirements and complexity of the manufacturing equipment.
3Ease of operation
If softer resin is used for the anti-sliding element, then user comfort and grip are improved, but the material selection and manufacturing process become more complex
Solution Approach 1:
The patent segments the anti-sliding element as a separate component that can be manufactured from softer resin through standard injection molding. This segmentation allows the use of appropriate soft materials for the anti-sliding portion without complicating the overall manufacturing process, as each component can be optimized independently for its specific functional requirements.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances user safety by preventing the mini pump from sliding during operation and reduces production costs and complexity by eliminating the need for bi-color injection molding, while maintaining comfort and functionality.
Implementation Method 1
the soft rubber material of the anti-sliding element could prevent a sliding of the pump on the user's hand
Implementation Method 2
the anti-sliding element and the handheld portion are respectively manufactured via injection-molding

AI summary
A mini pump having a body includes a head, a handheld portion extending from the head and having a groove, a nozzle device having a cover element, a nozzle and an anti-sliding element. The anti-sliding element is disposed on the head and partially received in the groove. The cover element engages the anti-sliding element to the cylinder and prevents the nozzle from coming off the body. The handheld portion and the anti-sliding element are made of resins with different hardnesses. The material of the handheld portion of the body is tougher than that of the anti-sliding element of the nozzle device.
