Banknote Validator Diverter Mechanism for Direct Passage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote validators face a blockage issue due to the diverter mechanism, preventing direct input and dispensing of banknotes or similar media between input/output apertures, and the opposing rotation of drive wheels complicates the transport process.
Innovation Solution
A diverter mechanism with a pivotal gate member and articulated winged members, linked to a motor-driven cam device, allows for two positions that enable unobstructed passage between input/output apertures and corrects the rotation sense of drive wheels to facilitate smooth transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a diverter mechanism is used to route banknotes through an intermediate validation transport branch, then banknote authentication capability is improved, but direct passage between input/output apertures is blocked
Solution Approach 1:
The diverter mechanism employs a motor-driven cam device that dynamically adjusts the position of articulated winged members between two positions: first position allowing direct passage between apertures, and second position routing banknotes through the intermediate validation branch. This dynamic reconfiguration resolves the contradiction by making the system adaptable to different operational modes.
Solution Approach 2:
The transport path is segmented into multiple independent routes: a direct path between input/output apertures and an intermediate validation transport branch. The articulated winged members act as segmentable dividers that can be positioned to open or close specific path segments, allowing selective activation of authentication mode or direct transport mode.
2Adaptability or versatility
If drive wheels rotate in opposite senses to convey banknotes, then bidirectional transport capability is improved, but transport smoothness deteriorates due to rotation conflicts
Solution Approach 1:
The system dynamically adjusts drive wheel rotation directions based on the diverter mechanism position. When the diverter is in the first position enabling direct passage, drive wheels rotate in the same sense for smooth transport. When the diverter routes through the intermediate branch, rotation directions are adjusted accordingly. This dynamic coordination eliminates transport conflicts while preserving bidirectional capability.
3Reliability
If the diverter mechanism blocks the direct path for authentication purposes, then validation reliability is improved, but device complexity increases
Solution Approach 1:
The articulated winged members serve multiple functions: they act as dividers to block paths, guide banknotes along transport routes, and coordinate with drive wheels for smooth transitions. The motor-driven cam device provides centralized control for both positioning the wings and coordinating drive wheel rotation. This multi-functionality reduces overall system complexity despite the added diverter mechanism.

AI summary
A banknote validator (2) comprising: a first banknote input/output aperture (3); a second banknote input/output aperture (4); a banknote transport path (5) interconnecting the first banknote input/output aperture (3) and the second banknote input/output aperture (14); an intermediate validation transport branch (11) disposed between the first and second banknote input/output apertures (3, 4); and a diverter mechanism (12) disposed proximal to an entrance to said intermediate validation transport branch (11); characterised in that the diverter mechanism (12) is moveable between: a first position in which the banknote transport path bypasses the intermediate validation transport branch (11) providing a direct passage between the first and second banknote input/output apertures (3, 4); and a second position in which the banknote transport path is indirect between the first banknote input/output aperture (3) and the second banknote input/output aperture (4) and is via the intermediate validation transport branch (11).
