Cash Box Closing Unit With Plate-Shaped Opener for Smooth Shutter Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash box mechanisms with jalousie-shaped shutters face issues with reliable and comfortable opening and closing due to large radius paths, leading to potential sticking and uncomfortable handling.
Innovation Solution
A cash box design incorporating a jalousie part and a plate-shaped part with engaging elements that automatically open and close, reducing friction and force required for operation, ensuring reliable and comfortable handling by engaging with device elements for automated teller machines or similar devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the shutter is moved along a path with a relatively large radius to ensure safe engagement between the cavity and the protrusion, then the reliability of opening and closing is improved, but the complexity of the mechanism increases and the shutter can easily get stuck
Solution Approach 1:
The shutter is divided into two functional parts: a jalousie-shaped portion for closing the opening and a plate-shaped portion with an engaging element for automated engagement. This segmentation allows each part to perform its specific function efficiently, reducing overall mechanism complexity while maintaining reliability
Solution Approach 2:
A plate-shaped intermediate element with an engaging element serves as a mediator between the shutter and the device chassis. This intermediary component simplifies the engagement mechanism by providing a dedicated interface that reduces the radius of movement required for reliable engagement
2Reliability
If the shutter is moved along a path with a relatively large radius to ensure safe engagement, then the reliability of opening and closing is improved, but the ease of operation deteriorates due to uncomfortable handling
Solution Approach 1:
The plate-shaped portion with the engaging element acts as an intermediary that reduces the movement radius required for reliable engagement. This allows the shutter to be moved along a smaller radius path while maintaining safe engagement, significantly improving ease of operation and handling comfort
Solution Approach 2:
By separating the shutter into a jalousie-shaped portion and a plate-shaped portion with engaging element, the design enables independent optimization of each component's function, allowing the engaging element to interact with the chassis protrusion over a shorter distance while the jalousie portion maintains its closing function

AI summary
The invention relates to a cash box (10) which comprises a housing (12) with an opening (16) for supplying notes of value to a storing compartment for storing notes of value and/or for removing notes of value from the storing compartment. Moreover, the cash box (10) has a closing unit (18) that comprises a jalousie part (32) and a plate-shaped part (34). The plate-shaped part (34) has a first engaging element (38) which is shaped in such a manner that, when the cash box (10) is being inserted in a device (102) for handling notes of value, the first engaging element (38) engages with the second engaging element (126) of the device (102) so that the closing unit is moved from a closing position to an open position. Moreover, the invention relates to a device (102) for handling notes of value.
