Cash Box Height Limiter for Automatic Note Feeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash boxes face difficulties in automatically feeding notes of value by machine due to lateral height limiters that obstruct the insertion process and cause notes to protrude and get pulled under others, leading to issues in the payment process.
Innovation Solution
A cash box design featuring a single height limiter on the cover that protrudes into a recess in the retaining element, eliminating the need for lateral height limiters, allowing notes to be fed straight in and ensuring secure retention without slipping, with adjustable fingers and recesses for optimal adaptation to note dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lateral height limiters are used to close the gap in the retaining element, then notes of value are prevented from slipping in, but the feeding process becomes more difficult and notes may protrude and get pulled under others
Solution Approach 1:
The patent removes the lateral height limiters from the base unit and integrates the height limiting function into a single height limiter on the cover. This extraction of the obstructing elements (lateral height limiters) eliminates the feeding problem while maintaining retention through the integrated cover-mounted height limiter that engages with the retaining element.
Solution Approach 2:
The patent combines the height limiting function and the gap-closing function into a single integrated height limiter mounted on the cover. This merger eliminates the need for separate lateral height limiters on the base unit, simplifying the feeding process while maintaining secure retention of notes through the engaging finger-recess mechanism.
2Reliability
If multiple height limiters are provided laterally, then the gap in the retaining element is always closed, but the device complexity increases
Solution Approach 1:
The patent merges multiple height limiters into a single integrated height limiter mounted on the cover. This single height limiter incorporates the functionality of multiple separate limiters through its finger elements that engage with corresponding recesses in the retaining element, reducing device complexity while maintaining reliable gap closure.
Solution Approach 2:
The single height limiter on the cover serves multiple functions: it limits the height of the receiving area, closes the gap in the retaining element through its finger engagement, and prevents notes from slipping. This multi-functional design eliminates the need for multiple separate components.
3Adaptability or versatility
If the height limiter is fixed on the base unit, then the receiving area height is limited, but automatic feeding is obstructed
Solution Approach 1:
Instead of mounting the height limiter on the base unit (traditional approach), the patent inverts the mounting location to the cover. This inversion allows the height limiter to be positioned away from the feeding path when the cover is open, enabling automatic feeding without obstruction, while still providing height limitation and adaptability when the cover is closed.

AI summary
The invention relates to a cash box (10, 100, 102) with a receiving area (24) for receiving a stack of banknotes and a first opening (18) that can be closed via a lid (16) for manually inserting and removing banknotes. A height limiter (36) for adjusting the height of the receiving area (24) is provided on the lid (16), wherein this height limiter (36) comprises at least one finger (40, 42) which, at least when the lid (16) is closed, projects into a recess (44, 46) of a retaining element (30).
