Banknote Deposit Device with Clamping Transport and Slit Shutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote deposit apparatuses have a large opening that poses a risk of banknotes being picked out from the storing box, compromising their security and integrity.
Innovation Solution
A banknote deposit apparatus with a clamping and transporting mechanism that stacks banknotes in a forwardly inclined position and transports them parallel to their surfaces, using a slit opening and shutter unit to securely store them, and a control unit to manage the storage and counting modes, ensuring the banknotes are securely stored and can be counted efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large opening is provided between the banknote escrow unit and the banknote storing cassette to allow banknotes to be let down, then the banknote transport function is improved, but the thief-proof property deteriorates as banknotes may be picked out through the opening
Solution Approach 1:
The opening is segmented into a slit opening with limited width, and a shutter unit is introduced to control access. The shutter unit divides the opening into an open state (allowing transport) and closed state (preventing pickup), resolving the contradiction between transport ease and security.
Solution Approach 2:
The shutter unit transforms the static large opening into a dynamic controlled aperture. It can switch between open and closed states based on operational requirements, allowing the system to adapt between transport mode (open) and security mode (closed).
2Reliability
If a shutter unit is introduced to control the opening for security purposes, then the thief-proof property is improved, but the device complexity increases
Solution Approach 1:
The shutter unit serves multiple functions: it acts as a security barrier, a transport guide, and an operational control mechanism. By consolidating these functions into a single component, the overall device complexity is minimized while achieving the security improvement.
Solution Approach 2:
The shutter unit acts as an intermediary element between the opening and the banknotes. It mediates the interaction by allowing controlled passage during transport while blocking access during storage, thereby achieving security without requiring complex barrier systems.
3Reliability
If the opening is kept closed to prevent banknote pickup, then the thief-proof property is improved, but the banknote counting function deteriorates as banknotes cannot be taken out
Solution Approach 1:
The shutter unit enables dynamic switching between closed (security) and open (counting) states. During storage, it remains closed to prevent pickup; during counting operations, it opens to allow banknotes to be removed, thus resolving the contradiction between security and operational accessibility.
Solution Approach 2:
The shutter unit operates periodically, remaining closed during storage periods and opening during counting periods. This periodic action allows the system to maintain security most of the time while providing periodic access for counting operations.
