Bottom-Opening Password Lock With Integrated Code Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bottom opening password locks have security issues due to password changes when incorrect codes are entered and a complex assembly process with numerous parts.
Innovation Solution
A simplified structure with a locking mechanism comprising a first and second bolt, a bolt pin, and a bolt spring, along with a shackle and password assembly featuring clutch sleeves, password wheels, and a code adjusting block, allowing for secure and easy assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a code adjusting block is used to adjust the code in existing password locks, then the password can be changed, but the lock has a large number of parts and a complex assembly process
Solution Approach 1:
The patent combines the code adjusting block with the password wheel assembly, making the code adjustment function integrated into the existing password wheel structure rather than a separate mechanism. This merging reduces the number of independent parts and simplifies the assembly process while maintaining the ability to adjust passwords.
Solution Approach 2:
The password wheels serve multiple functions: they are used for entering the password during normal operation and also serve as the adjustment mechanism for changing the password. The code adjusting block is integrated with the password wheel structure, allowing the same components to handle both password entry and password modification, thereby reducing overall device complexity.
2Reliability
If multiple components are used in the locking mechanism, then the locking function is achieved, but the assembly process becomes complex and performance becomes unstable
Solution Approach 1:
The patent integrates the locking mechanism components (locking block, spring, and related structures) into a compact arrangement where fewer independent parts are needed. The locking block works in conjunction with the password wheel assembly in a unified structure, reducing the total number of components while maintaining reliable locking functionality.
Solution Approach 2:
The locking mechanism is segmented into functional modules (locking block, spring mechanism, password wheel assembly) that can be assembled in a standardized sequence. This modular segmentation allows for simpler assembly procedures and improves performance stability by reducing the number of interfaces between components.

AI summary
A bottom opening password lock comprises a lock case and a liner arranged in the lock case as well as a shackle connected with a top of the lock case, a lower cover is arranged on a lower side of the liner, and a locking mechanism and a password assembly are installed between the liner and the lower cover; the locking mechanism comprises a first bolt and a second bolt which are arranged correspondingly as well as a bolt pin arranged between the first bolt and the second bolt, and a bolt spring is installed on the bolt pin; the shackle is pressed down to make the forcing push head push clutch sleeves to move axially, thus the clutch sleeves and password wheels can be separated to realize code adjusting. The utility model is simple in structure and convenient to use.
