Movable Base Pan Cash Box for Jam-Free Note Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash boxes with pivotable retraction flaps often result in notes of value being jammed or not withdrawn correctly, leading to errors and the need for manual intervention, as the notes must be moved relative to the base element during removal and insertion into devices.
Innovation Solution
A cash box design featuring a movable base pan that can transition between a retracted and removal position, eliminating the need for notes to be moved relative to the base element, with an integrated pressure unit and side walls to secure and stabilize the notes, and a shutter mechanism that automatically adjusts the base pan's position for secure feeding and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pivotable retraction flap is used to separate the receiving area from the opening, then the notes of value can be protected when the shutter is closed, but the notes of value may be jammed, not withdrawn correctly, or pulled under the stack during movement
Solution Approach 1:
Instead of moving the notes relative to the base element (conventional approach), the patent inverts the approach by moving the base element itself relative to the housing. The base pan with integrated base element translates between retracted and removal positions, carrying the notes with it, thereby eliminating the harmful relative movement between notes and base element that causes jamming and handling errors.
Solution Approach 2:
The patent merges the base element with the base pan, creating an integrated movable assembly. The base element is no longer a separate stationary component but is combined with the base pan to form a single movable unit that translates together with the notes, eliminating relative movement and the associated problems of jamming and misalignment.
2Stability of the object's composition
If the retraction flap is moved to secure the stack deeper into the cassette, then the notes are protected during transport, but the notes must be moved relative to the base element which causes jamming and handling errors
Solution Approach 1:
Instead of moving the notes relative to the base element to achieve secure positioning, the patent inverts the approach by moving the base element with the notes. The base pan translates the entire assembly (base element + notes) to the retracted position during transport, maintaining stability without harmful relative movement, and to the removal position for easy feeding and removal operations.
Solution Approach 2:
The patent introduces dynamic positioning of the base pan between retracted and removal positions. The base pan can dynamically adjust its position based on operational requirements: retracted for stable transport and removal for easy note feeding, with smooth translation between states enabled by the movable base pan design.
3Reliability
If the base pan is made movable to eliminate relative movement of notes, then jamming and handling errors are prevented, but the device complexity increases due to the movable base pan mechanism
Solution Approach 1:
The patent segments the cash box into distinct functional modules: a movable base pan assembly and a fixed housing. The base pan with integrated base element forms an independent movable module that can translate relative to the housing, simplifying the overall design by localizing the movement function to a specific segment rather than requiring complex mechanisms throughout the entire device.
Solution Approach 2:
The movable base pan acts as an intermediary between the fixed housing and the notes. It provides a simple translation mechanism that carries the notes between retracted and removal positions without requiring complex direct manipulation mechanisms, thereby reducing overall device complexity while maintaining high reliability.

AI summary
The invention relates to a cash box (10) comprising a housing (12) and a base tray (16) arranged within the housing, wherein the base tray (16) defines a receiving area (28) for receiving the stack of banknotes (22). The base tray (16) is movable relative to the housing (12) between a removal and a retraction position.
