Self-Locking Cashbox Anti-Theft Plate Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cash storage equipment lacks enhanced security features to prevent unauthorized access and theft, despite existing locking mechanisms.
Innovation Solution
A self-locking cash deposit equipment with a cashbox featuring an anti-theft plate and anti-theft plate locking mechanism, allowing cash to be inserted and stored securely by switching between locking and unlocking states, ensuring the anti-theft plate can only be moved to an opening position when the locking mechanism is in an unlocking state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional locking mechanism is used to allow cashbox removal for cash insertion, then ease of operation is improved, but security is worsened due to potential unauthorized removal
Solution Approach 1:
The anti-theft plate is pre-positioned to cover the opening, and the locking mechanism is pre-configured to prevent removal. The system performs preliminary security establishment before any cash insertion operation, ensuring the cashbox cannot be unauthorizedly removed while still allowing legitimate operations through proper authentication
Solution Approach 2:
The anti-theft plate acts as an intermediary element between the opening and the external environment. It mediates access by being movable to allow cash insertion when unlocked, yet remains in a blocking position to prevent unauthorized removal, thus resolving the contradiction between ease of operation and security
2Reliability
If an anti-theft plate is added to cover the opening for enhanced security, then reliability is improved, but device complexity is worsened
Solution Approach 1:
The anti-theft plate locking mechanism is merged with the existing cashbox structure. The locking mechanism integrates the anti-theft plate control, latch members, and spring elements into a unified system that works together to provide security without requiring completely separate independent components, thus reducing overall device complexity while maintaining enhanced security
Solution Approach 2:
The anti-theft plate serves multiple functions: it covers the opening to prevent unauthorized access, acts as a barrier to cashbox removal, and works with the locking mechanism to control access. This multi-functionality reduces the need for additional separate security components, thereby limiting the increase in device complexity
3Ease of operation
If the anti-theft plate is made movable to allow cash insertion, then ease of operation is improved, but security is worsened due to potential unauthorized opening
Solution Approach 1:
The anti-theft plate is designed as a dynamic component that can change its state between locked and unlocked positions. When locked, it provides security by blocking access; when unlocked through proper authentication, it moves to allow cash insertion. This dynamic behavior resolves the contradiction by providing both security and operational ease at different times in the same system
Solution Approach 2:
The locking mechanism incorporates feedback through the spring element that automatically returns the anti-theft plate to its secured position after cash insertion. The system provides feedback control ensuring that the plate only moves when properly authenticated and automatically resets to protect against unauthorized opening, thus maintaining security while enabling operation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The equipment provides enhanced security by preventing unauthorized removal of the cashbox and ensuring cash can be safely stored, with the anti-theft plate automatically closing after use, requiring a legitimate key for operation.
Implementation Method 1
a first extension spring connected between the first latch member and the box body. The first extension spring is configured to exert a restoring force on the first latch member
Implementation Method 2
a first latch member that includes a first main body pivotally connected to the box body about a first pivot point

AI summary
A cashbox includes a box body with a first opening, an anti-theft plate with a second opening, and an anti-theft plate locking mechanism mounted to the box body and including a first latch member that includes a first main body pivotally connected to the box body and a latch portion extending from the first main body. The anti-theft plate is movable to an opening position, where the second opening communicates with the first opening. The anti-theft plate locking mechanism is switchable between a locking state, where the latch portion prevents the first opening from moving to the opening position, and an unlocking state, where the latch portion allows the anti-theft plate to move to the opening position.
