Money Storage Detachment Interlock to Prevent Base Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional banknote handling devices allow storage detachment in a single direction, risking damage if improperly detached.
Innovation Solution
A money storage device with a base, switch, and restrictor that ensures detachment through a controlled procedure by disconnecting the storage from the base before detachment, using mechanical and electrical connections, and restricting movement with switches and locks to prevent damage to the base.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the storage is connected to the base with a simple mechanical connection, then the ease of operation is improved, but the reliability deteriorates due to risk of damage from improper detachment
Solution Approach 1:
The patent applies preliminary action by requiring the operator to first disconnect the storage from the base through a controlled procedure before attempting detachment. The switch must be operated to disconnect the connection before the storage can be removed, preventing damage by ensuring proper sequence of operations.
Solution Approach 2:
The patent implements feedback through the switch mechanism that provides tactile or positional feedback to indicate whether the storage is properly connected or disconnected. This feedback guides the operator through the correct detachment procedure, reducing the risk of damage from improper handling.
2Reliability
If a control procedure with switch and restrictor is added, then the reliability is improved by preventing damage, but the device complexity increases
Solution Approach 1:
The patent merges the switch and restrictor into an integrated control mechanism where the switch both disconnects the electrical/mechanical connection and activates the restrictor to prevent unintended detachment. This consolidation reduces complexity compared to having separate independent mechanisms.
Solution Approach 2:
The restrictor acts as an intermediary element between the storage and base, providing a mechanical barrier that prevents direct detachment until the switch is operated. This intermediary component simplifies the overall control logic by adding a single protective mechanism rather than multiple complex control systems.
3Ease of operation
If the storage can be detached in any direction, then the ease of operation is improved, but the object-generated harmful factors worsen due to potential damage to base
Solution Approach 1:
The patent applies preliminary anti-action by using the restrictor to prevent harmful detachment movements before they can cause damage. The restrictor mechanically blocks the storage from being pulled away from the base in unauthorized directions, countering potential damaging actions before they occur.

AI summary
A money storage device includes: a storage; a base that supports the storage; a switch that switches between connection and disconnection between the storage and the base; and a first restrictor that restricts detachment of the storage from the base with the storage connected to the base and to release restriction of the detachment of the storage in a case where the switch disconnects the storage and the base from each other.
