Dispenser Mounting Arrangement Hiding Pump Body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices with dispensing pumps often require structural modifications and do not aesthetically conceal the pump body, limiting the types of pumps that can be used and compromising appearance.
Innovation Solution
A packaging device featuring a fixing element with a double cylindrical structure, including an internal chimney, allows for secure attachment of various pump types without modifications, while a coaxial cylinder and radial projections or deformable materials ensure a snug fit and concealment of the pump body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional fixing element is used to secure a dispensing device in the bottle neck, then the pump body can be fixed, but the pump body remains visible and aesthetically unpleasing
Solution Approach 1:
The fixing element is designed with a double cylindrical wall structure comprising an outer wall and an inner wall forming an internal chimney. The pump body is nested within the internal chimney, completely hidden from external view. This nesting structure allows the pump to be secured while maintaining aesthetic appearance, as the fixing element itself serves as a cosmetic cover.
Solution Approach 2:
The fixing element is segmented into distinct functional zones: an outer wall for aesthetic appearance and structural support, an internal chimney for pump housing, and a retaining element for secure attachment. This segmentation allows each part to optimize its specific function while working together as a unified cosmetic cover.
2Ease of operation
If a plug-type pump is used, then the pump can be inserted by force into the fastening element, but structural modifications are required to the pump
Solution Approach 1:
The internal chimney is designed with universal dimensions and features (retaining bead, radial projections) that can accommodate multiple pump types including snap-on, crimp-on, and screw-on pumps. The chimney acts as a standardized interface that works with various pump configurations without requiring modifications to the pumps themselves, thereby achieving multi-functionality.
Solution Approach 2:
The internal chimney serves as an intermediary component between the fixing element and the pump body. It provides a standardized mounting interface that mediates between the cosmetic cover structure and various pump types, allowing easy installation without direct modification to the pump designs.
3Ease of manufacture
If the fixing element is designed to completely conceal the pump body, then aesthetic appearance is improved, but the structure becomes more complex
Solution Approach 1:
The cosmetic cover function and the pump securing function are merged into a single fixing element structure. The double cylindrical wall design combines the outer aesthetic shell with the inner mounting chimney, eliminating the need for separate cosmetic covers and simplifying the overall assembly despite the sophisticated appearance.
