Fluid Dispensing Pump Lock With Integrated Telescopic Safety Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid substance dispensing devices suffer from damage and malfunction due to impacts during transportation or use, particularly when a removable safety element is absent, leading to pump protection issues and potential loss of the safety element.
Innovation Solution
A fluid substance dispensing device with an integrated safety system comprising a base and a mobile ring that automatically activates and deactivates based on the position of the dispensing button, ensuring protection against impacts by preventing the mobile ring from lowering, thus integrating the safety system as an integral part of the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable safety element is used to protect the pump from impacts, then the pump is protected during transportation or use, but the safety element may come off during severe drop tests, leaving the pump without protection
Solution Approach 1:
The safety element is integrated into the pump structure by forming it as a continuous piece with the pump body, eliminating the removable component that could detach. This merging ensures the safety protection remains permanently attached to the pump throughout its service life.
Solution Approach 2:
The safety element is pre-formed as an integral part of the pump during manufacturing, so no separate assembly or attachment step is needed. The safety protection is already in place before the pump enters service, ensuring immediate protection without risk of detachment during use.
2Reliability
If a removable safety element is used, then the pump can be protected, but the user must remove the safety element before using the device and normally the element is thrown away or can be lost
Solution Approach 1:
The safety element is merged with the pump body as a single integrated component, eliminating the need for users to remove or handle separate safety elements. This integration removes the operational complexity and loss risk associated with removable safety components.
3Ease of operation
If the safety element is removed, then the user can operate the device, but in the event of falls when the safety element is absent, the device may break or experience malfunctions
Solution Approach 1:
The safety element is combined with the pump body, ensuring protection is always active during operation. This eliminates the scenario where the safety element is removed, thereby preventing the risk of device breakdown or malfunction during falls or impacts.

AI summary
A fluid substance dispensing device comprising a manually operated pump (1) equipped with a cup-shaped body (2), inside which a communicating compression chamber (3) is formed at least during a filling step achieved by means of a first filling valve element (4) and a stem (5A) which is coupled with a dispensing button (6) so that the movement of the stem (5A) towards the cup-shaped body (2) reduces the volume of the compression chamber by pushing any substance present in the compression chamber through a cavity (5B) in the said stem (5A) - and a ring nut (7) for fastening at least the cup-shaped body (2) to a container (20) to which the pump (1) can be coupled and which can contain said substance (S), the dispensing button (6) being configured to rotate at least between a first unlocked position in which it is allowed a free stroke, and a second locked position in which at least one part thereof (9, 6A) encounters a stop (10, 12A) on the pump (1) and travel of the dispensing button (6) towards the cup-shaped body is prevented; between the dispensing button (6) and the ring nut (7) or between the dispensing button (6) and the cup-shaped body (2), there is a safety system (13) formed of at least a base (11) and a mobile ring (12) which translates telescopically with respect to the base (11) so that, when the dispensing button (6) is rotated to the locked position, the mobile ring (12) is extended with respect to the base (11) and at least a first part of the base (11A) encounters a portion (12A) of the mobile ring (12) so as to prevent the mobile ring (12) lowering towards the base (11), a second part of the mobile ring (12) encountering a flange (6A) or a step on the dispensing button (6) and thereby preventing the dispensing button (6) from lowering, and when the dispensing button (6) is rotated to the unlocked position the mobile ring (12) is lowered telescopically with respect to the base (11), leaving the dispensing button (6) free to travel.
