Dispenser Head Telescopic Movement and Rotation Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensers lack an efficient and adjustable connection between the dispensing tube and head, which affects the dispensing mechanism's functionality, particularly in transitioning between extended and retracted positions.
Innovation Solution
The dispensing head is designed as a non-rotatable continuation section of the dispensing tube with a dispensing closure part, allowing for circumferential and vertical displacement between openings, enabling a snap-in assembly and rotatable adjustment relative to the reservoir, ensuring a flush interaction in the extended position and closure in the retracted position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the dispensing head is firmly connected to the dispensing tube, then the connection is stable and reliable, but the ability to adjust position and achieve flush interaction is limited
Solution Approach 1:
The dispensing head is divided into separate functional components: a dispensing closure part that can rotate relative to the dispensing tube, and a dispensing head part that can be positioned independently. This segmentation allows the connection to maintain reliability through firm coupling while enabling position adjustment through controlled movement of individual segments.
Solution Approach 2:
The connection between the dispensing head and dispensing tube is made dynamic rather than static. The dispensing closure part can rotate to different positions, and the dispensing head part can move between extended and retracted positions, allowing the system to adapt to different operational requirements while maintaining a firm connection.
2Ease of operation
If the dispensing head is rotatable relative to the reservoir, then user control and positioning flexibility are improved, but the complexity of the connection mechanism increases
Solution Approach 1:
The rotational adjustment function is extracted as a separate feature of the dispensing closure part, which can rotate independently relative to the dispensing tube. This allows users to control the dispensing head position without complicating the overall connection mechanism, as the rotation is achieved through a dedicated component rather than a complex integrated system.
Solution Approach 2:
The dispensing closure part serves multiple functions: it provides a firm connection to the dispensing tube, enables rotational adjustment for user control, and maintains alignment with the dispensing opening. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in overall device complexity.
3Reliability
If the dispensing head moves telescopically to the dispensing tube, then flush interaction in extended position and closure in retracted position are achieved, but the complexity of the dispensing head structure increases
Solution Approach 1:
The dispensing head part is designed with a nested structure where the dispensing closure part can rotate within the dispensing head part, which itself can move telescopically relative to the dispensing tube. This nesting allows multiple functions (rotation and telescopic movement) to be achieved within a compact structure, limiting the increase in overall complexity.
Solution Approach 2:
The telescopic movement and rotational adjustment functions are merged into a single integrated dispensing head structure. The dispensing closure part combines both rotational capability and telescopic movement capability, eliminating the need for separate mechanisms for each function and thereby limiting the increase in structural complexity.

AI summary
The invention relates to a dispenser for issuing liquid to paste-like substances, comprising a dispenser head with a dispenser mouth, a supply chamber and a dispenser top section, characterized in that the dispenser head can move relative to the dispenser top section from a dispenser-ready position to a lowered position and vice versa. To achieve favorable transport certainty and/or a non-use position, the invention proposes that the dispenser head be moveable relative to the dispenser top section from a dispenser-ready position to a lowered position and vice versa.
