Automatic Reset Lock Mechanism via Magnetic Wheel Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional combination locks do not automatically reset the dial combination after being unlocked and locked, leading to potential leakage of the correct combination code due to user forgetfulness.
Innovation Solution
An automatic messy code character wheel lock mechanism that utilizes a character wheel shaft with movable bushings and magnets to automatically reset the combination code to an incorrect setting after each use, ensuring security by preventing accidental exposure of the correct code.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock displays the correct combination code when unlocked and locked, then the user can see the combination code, but the correct combination code may leak out due to user forgetfulness to reset the dials
Solution Approach 1:
The lock automatically resets the character wheels to a random incorrect combination code immediately after each locking operation, before any potential leakage can occur. This preliminary reset action eliminates the security vulnerability where the correct code might be exposed if the user forgets to reset the dials manually.
2Reliability
If the user manually resets the dials after locking, then the combination code is changed, but the operation becomes inconvenient and may be forgotten
Solution Approach 1:
The lock system performs the reset operation automatically without requiring user intervention. The character wheels are self-resetting through a mechanical mechanism that randomizes the combination code after each lock cycle, eliminating the need for manual dial resetting and ensuring the code is always changed.
3Extent of automation
If automatic reset mechanism is added to the lock, then the combination code is automatically changed, but the device complexity increases
Solution Approach 1:
The patent uses a magnetic field-based detection system instead of complex mechanical sensors to detect the lock state. Magnets embedded in the character wheels interact with magnetic sensors on the lock case, enabling automatic detection of wheel positions and triggering the reset mechanism through electromagnetic fields rather than complex mechanical linkages.
