Coded Lock Inner Wheel Mechanism for Self-Service Password Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coded locks often require professional unlocking when the password is forgotten, leading to time wastage and safety concerns due to complex retrieval processes.
Innovation Solution
A password-retrieving apparatus for coded locks featuring a combined elastic and inner wheel mechanism, driven by a lock cylinder and toggling disk, allowing users to retrieve the password using a spare key without professional assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional unlocking is used to retrieve the password, then the lock can be unlocked, but it wastes time and money
Solution Approach 1:
The patent implements a self-service password retrieval mechanism where the user can independently retrieve their password by inserting a spare key into the lock cylinder and rotating it. This eliminates the need for professional unlocking services, allowing users to resolve password issues immediately without time loss or additional costs.
2Reliability
If professional unlocking is used to retrieve the password, then the lock can be unlocked, but it incurs additional costs
Solution Approach 1:
The patent implements a self-service password retrieval mechanism where the user can independently retrieve their password by inserting a spare key into the lock cylinder and rotating it. This eliminates the need for professional unlocking services, allowing users to resolve password issues immediately without time loss or additional costs.
3Ease of operation
If the password retrieval process is made simple, then user convenience is improved, but the structure may become more complex
Solution Approach 1:
The patent makes the lock cylinder serve multiple functions: it acts as both the normal unlocking component and the password retrieval mechanism. By rotating the lock cylinder with a spare key, the user triggers a sequence that rotates the inner wheel to display the password. This multi-functionality simplifies the overall structure while enabling easy password retrieval.
Solution Approach 2:
The patent employs a nested structure where the inner wheel is positioned within the lock cylinder assembly. The inner wheel contains the password display components and is rotated by the lock cylinder mechanism. This nested arrangement allows the password retrieval function to be integrated within the existing lock structure without adding significant external complexity.
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
Enables simple and cost-effective password retrieval by rotating the lock cylinder, reducing the need for professional help and minimizing structural complexity while ensuring accuracy.
Implementation Method 1
mounted between a lock shell and a lock cover through a big spring; the lock body moves relatively under the action of a big spring
Implementation Method 2
a small spring is arranged between the adjusting rod and a lock cover; the adjusting rod moves inwards under the action of the small spring
