Safe Unlocking Machine Direction Switch Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safe unlocking machines have a complex structure due to the need for a return mechanism to move the safe body from a retraction position back to its original home position, which complicates the design and operation.
Innovation Solution
A safe unlocking machine with an operation unit that can switch directions based on detection signals, allowing it to move the safe body between a closed and open position, eliminating the need for a separate return mechanism by using a single handle for both movements, and incorporating sensors and solenoids to control the operation direction switching mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring return mechanism is used to move the safe body from retraction position to home position, then the safe body can be returned automatically, but the machine structure becomes complicated
Solution Approach 1:
The patent combines the forward movement function and return movement function into a single operation unit (handle). By rotating the handle in different directions, the safe body can move both forward to the retraction position and return to the home position, eliminating the need for separate return mechanisms like springs.
Solution Approach 2:
The operation unit (handle) is designed to perform multiple functions: it can move the safe body forward when rotated in one direction and move the safe body backward when rotated in the opposite direction. This multi-functionality replaces what would traditionally require separate mechanisms for each direction of movement.
2Device complexity
If a single operation unit is used for both forward and reverse movement, then the machine structure is simplified, but control of movement direction becomes more complex
Solution Approach 1:
The patent incorporates detectors that monitor the position and movement state of the safe body, providing feedback signals to a control unit. The control unit processes this information and generates appropriate control signals to manage the operation direction switching mechanism, ensuring correct directional control despite the simplified mechanical structure.
Solution Approach 2:
The patent introduces an operation direction switching mechanism that acts as an intermediary between the operation unit and the safe body. This switching mechanism translates the rotational direction of the handle into corresponding linear movement directions of the safe body, managing the complexity of directional control separately from the mechanical structure.

Function Achieved in This Case
This simplifies the machine's structure, enhances operability, and reduces the risk of operation errors by allowing a single handle to perform both forward and reverse rotations, ensuring reliable and efficient collection of items from safes.

AI summary
A safe unlocking machine is provided with: an operation direction switching mechanism for selectively switching between a first direction allowance state in which only the operation of an operation unit in the first direction is allowed, and a second direction allowance state in which only the operation of the operation unit in the second direction is allowed; detectors for detecting the action of the safe unlocking machine and generating a detection signal; and a switching controller for controlling an operation direction switching mechanism on the basis of the detection signal from the detectors and thereby selectively setting the direction of movement of the operation unit to the first direction or the second direction.
