Connector With Oblique Guide Faces For Controlled Discharge Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connectors for discharge devices require two steps for removal, involving lateral pressure and axial force, which can lead to user injury and aerosol formation due to abrupt pull-off, causing contamination and safety risks.
Innovation Solution
A connector with obliquely oriented guide faces on opposite side faces that, when pressed together, slide radially to generate an axial force for controlled removal without abrupt separation, using a holding arrangement that can be released with manual pressure, reducing the need for axial force and minimizing risk of injury or contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional holding arrangement is used to secure the accessory on the discharge device, then the accessory is firmly held during operation, but removal requires two steps (lateral pressure followed by axial force) which can cause abrupt pull-off and safety risks
Solution Approach 1:
The guide faces are pre-positioned on the connector to perform the release action automatically when lateral pressure is applied. The oblique guide faces are already oriented to convert radial motion into axial motion, so no additional axial force step is needed during removal.
Solution Approach 2:
The oblique guide faces act as an intermediary mechanism between the lateral pressing action and the axial release motion. They mediate the force transformation, converting the simple lateral pressure into controlled axial detachment without requiring direct axial force application.
2Ease of operation
If two-step removal process is used (lateral pressure then axial force), then the holding arrangement can be released, but the abrupt pull-off may cause user injury and aerosol formation
Solution Approach 1:
The guide faces are pre-configured to perform the safe release function. When lateral pressure is applied, the oblique guide faces automatically initiate the axial detachment motion in a controlled manner, preventing abrupt pull-off before it can cause harm.
Solution Approach 2:
The oblique guide faces cushion the release process by gradually converting lateral force into axial motion. This progressive force transformation acts as a buffer, preventing the sudden jerky motion that would otherwise cause injury or aerosol formation.
3Ease of operation
If lateral pressure is applied to release the holding arrangement, then the accessory can be detached, but axial force must still be applied to overcome adhesive and friction forces
Solution Approach 1:
The oblique guide faces serve as a mechanical intermediary that transforms the applied lateral force into axial detachment force. This force transformation eliminates the need for the user to directly apply axial force, as the guide faces generate the necessary axial component automatically.
Solution Approach 2:
The solution moves the release operation from a two-dimensional sequence (lateral then axial) to a single-dimensional action (lateral pressure only). The oblique guide faces handle the dimensional transformation, converting radial input into axial output automatically.
4Reliability
If the connector is designed with a holding arrangement for secure attachment, then reliable connection is achieved, but the removal process becomes complex requiring multiple manipulations
Solution Approach 1:
The guide faces are integrated directly into the connector structure that also contains the holding arrangement. This merging of the release mechanism into the connector body eliminates the need for separate release components or multi-step procedures, simplifying the overall removal process.
Solution Approach 2:
The connector structure serves multiple functions: the holding arrangement provides secure attachment, while the integrated guide faces provide the release function. This multi-functionality reduces the number of separate components and simplifies the removal operation to a single manipulation.
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
The connector allows for safe and controlled removal from the discharge device with a single manipulation, reducing the risk of injury and aerosol formation, ensuring a guided and jolt-free detachment process.
Implementation Method 1
Two guide faces (9) which are oriented obliquely with respect to the longitudinal direction (L) of the discharge device (1) in the direction of the latter are provided on two opposite side faces (16, 17) of the connector (6)

AI summary
The invention relates to a discharge device (1) comprising a tank housing (3) having at least one outlet (4) at one end and having a drive means at the opposite end. A connector (6) can be placed over the outlet (4) on the discharge device. The connector comprises a releasable mounting device that can be released by manual pressure on two opposite side surfaces of the connector. One guide surface (9) is provided on each of the two opposite side surfaces, each being oriented diagonally to the longitudinal axis (L) of the discharge device (1) and spaced in the direction of the discharge device. The connector is placed over the outlet on the discharge device in a mounting position. The guide surfaces (9) are moved radially toward each other in a released position by pressure (F) on the side surfaces. The guide surfaces thereby slide on an edge (15) of the discharge device (1), and the force is diverted to the edge (15), so that the connector (6) is axially displaced away from the drive direction in the released position.
