Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional banknote handling devices allow storage detachment only in one direction, risking damage if improperly detached.

Innovation Solution

A money storage device with a base, switch, and restrictors that ensure appropriate detachment by restricting and releasing the connection between the storage and base, using mechanical and electrical connections, and a lock mechanism to control detachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If the storage is mechanically connected to the base for stable support, then the stability and support function is improved, but the risk of damage during improper detachment increases

Engineering Contradiction:

Improvestability of storage connectionVSAvoiddamage risk during detachment

Core Design Contradiction:

Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The switch performs a preliminary disconnection action before the storage is detached. When the switch is activated, it disconnects the electrical connection between the storage and base beforehand, ensuring that if detachment occurs, only the mechanical connection is broken without damaging electrical components. This preliminary protective action prevents harmful damage while maintaining stable connection during normal operation.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If the storage is easily detachable for maintenance and access, then the ease of operation is improved, but the risk of accidental damage increases

Engineering Contradiction:

Improveease of storage detachmentVSAvoiddamage risk during detachment

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The switch acts as an intermediary mechanism between the storage and base. It provides a controlled disconnection interface that allows easy detachment through activation, while simultaneously protecting against accidental damage by ensuring proper disconnection sequence. The intermediary switch mediates the interaction, making detachment easy when intended while preventing damage when not intended.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If a lock mechanism is added to control detachment procedure, then the reliability of proper detachment procedure is improved, but the device complexity increases

Engineering Contradiction:

Improvereliability of detachment procedureVSAvoidcomplexity of connection mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The switch combines multiple functions into a single component: it serves as both the electrical connection interface and the detachment control mechanism. By merging the electrical disconnection and mechanical detachment control into one integrated switch, the reliability of the detachment procedure is improved without significantly increasing device complexity. The unified switch ensures proper procedure while maintaining simplicity.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A money storage device (4) includes: a storage (5); a base (42) that supports the storage; a switch (6) that switches between connection and disconnection between the storage and the base; and a first restrictor (7) 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.
