Multi-Position Axial Engagement for Pump Fixing Rings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening devices for fluid dispensers lack modularity in axial positioning, restricting flexibility in accommodating different container configurations, as they typically allow only a single axial position for the hoop relative to the ring.
Innovation Solution
A fastening device with a covering hoop and fixing ring that includes multiple mutual engagement elements, allowing the hoop to be axially offset and locked in distinct positions, formed by either the hoop or the ring, enabling flexible axial alignment based on container configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single axial position is used for the hoop on the ring, then the structure is simple, but the adaptability to different container configurations is limited
Solution Approach 1:
The retention system is segmented into multiple discrete engagement elements (protrusions and corresponding recesses) distributed at different axial positions on the ring and hoop. This segmentation allows the hoop to be retained at multiple distinct axial positions, providing adaptability to different container configurations while maintaining a relatively simple overall structure through modular engagement points.
2Manufacturing precision
If the hoop is pressed more or less on the ring to modify axial position, then the axial position can be adjusted, but the positioning is not stable and precise
Solution Approach 1:
The system transitions from a static single-position retention to a dynamic multi-position retention system. The hoop can be easily adjusted to different axial positions by engaging with different protrusion-recess pairs during assembly, and once engaged, each position provides stable and precise positioning through the mechanical interlocking of the engagement elements.
3Adaptability or versatility
If multiple mutual engagement elements are introduced, then axial positioning flexibility is improved, but the device complexity increases
Solution Approach 1:
The multiple engagement elements serve multiple functions: they provide axial positioning flexibility, ensure stable retention at each position, and maintain structural integrity. The protrusions and recesses are designed to work together as a universal retention mechanism that can accommodate various container configurations while keeping the overall device design unified and systematic rather than adding disparate components.

AI summary
The invention relates to a fixing device for fixing a distribution element (4), such as a pump or a valve, to the neck of a recipient (31). Said device comprises a fixing ring (1) provided with means for fixing (12) the distribution element to the neck of the recipient and stop means (13), and an outer band (2) which axially engages from top to bottom around the ring (1). Said outer band comprises adhesion means (25) which co-operate with the stop means in order to form means for axially holding the band on the ring. The inventive fixing device is characterised in that the holding means comprise a plurality of mutually engaging elements defining distinct axial engagement positions for adhering the band to the ring.
