Plaster Dispenser Form Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Plaster dispensers lack effective security measures to prevent unauthorized removal of the refill unit, allowing unauthorized access and potential misuse.
Innovation Solution
A form-fitting form lock mechanism is integrated into the dispenser housing, where a first form-locking part on the receiving box engages with a second resilient form-locking part inside the dispenser, securing the plaster refill unit against unauthorized removal and allowing authorized access with a key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the plaster refill unit is made freely accessible in the dispenser housing, then ease of operation is improved, but security against unauthorized removal deteriorates
Solution Approach 1:
The form lock mechanism transitions between locked and unlocked states dynamically. The resilient second form-locking part can be deflected by the form key to release the engagement, allowing authorized removal while maintaining security during normal operation.
Solution Approach 2:
The form key acts as an intermediary tool that mediates between the user and the form lock mechanism. It provides the necessary action to deflect the resilient form-locking part and release the plaster refill unit without requiring direct access to the engagement components.
2Reliability
If a form lock mechanism is added to prevent unauthorized removal, then security is improved, but device complexity increases
Solution Approach 1:
The form lock mechanism is merged with the existing structural components of the dispenser housing. The first form-locking part is integrated into the receiving box, and the second form-locking part is incorporated into the dispenser housing, combining security functionality with structural elements.
Solution Approach 2:
The form key is designed to be inserted into a recess in the dispenser housing, nesting the key within the housing structure. The form key engages with the form lock mechanism that is itself nested within the housing, creating a compact integrated system.
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 form lock effectively prevents unauthorized removal of the plaster refill unit while allowing authorized individuals to access and replace it, maintaining the dispenser's accessibility and security.
Implementation Method 1
a second form-locking part (14b) which is arranged resiliently in the interior (13) of the dispenser and engages in a form-fitting manner with the first form-locking part (14a)

AI summary
The invention relates to a plaster dispenser (1) with a dispenser housing (2) and at least one plaster refill unit (3) arranged in the dispenser housing (2). The plaster refill unit (3) has a receiving box (4) and at least one plaster bundle (7) which is fixed in an interior compartment (6) of the receiving box (4) and comprises several individual plasters (8) that can be removed from the plaster refill unit (3) at an open dispensing side (10) of the receiving box (4) in the dispensing direction (12). The at least one plaster refill unit (3) is arranged in an interior compartment (13) of the dispenser housing (2) so as to be removable from it in the dispensing direction (12). According to the invention, the at least one plaster refill unit (3) is detachably fixed in the interior compartment (13) of the dispenser housing by at least one positive locking mechanism (14).In this arrangement, a first form-locking part (14a) formed on the receiving box (4) and a second form-locking part (14b) spring-loaded in the dispenser interior (13) interlock perpendicular to the dispensing direction (12). As a result, the plaster refill unit (3) cannot be removed from the dispenser interior (13) when the form-lock (14) is closed, and can be removed when the form-lock (14) is open.
