Safe Lock Mechanism with Common Fastening Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional safes are cumbersome, time-consuming to open for security checks, and their locking mechanisms are complex, compromising security; they also lack flexibility in key management and are vulnerable to lock failure or power outages.
Innovation Solution
A lock mechanism with a common fastening member that can be freely mounted and demounted, featuring a false lock and latch system that allows for multiple locking and unlocking methods, including a concealed operating portion to maintain security even if one lock is compromised, and a lightweight, compact design using fiber-reinforced plastic for enhanced usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional safe uses multiple locks for security, then security is improved, but the locking/unlocking operation becomes complicated and time-consuming
Solution Approach 1:
The patent merges multiple lock operations into a single unified operation. The operating portion is designed to simultaneously control multiple latches (first latch and second latch) through one rotational motion, allowing the user to lock or unlock both latches at the same time rather than operating each lock separately. This reduces operational complexity while maintaining multi-lock security.
Solution Approach 2:
The single operating portion serves multiple functions: it can rotate to lock the first latch, rotate to unlock the first latch, rotate to lock the second latch, and rotate to unlock the second latch. This multi-functional design allows one component to perform what previously required multiple separate locking mechanisms, simplifying user interaction while maintaining security through multiple latches.
2Reliability
If a conventional safe uses a sturdy, heavy quadrilateral handle for anti-theft purpose, then security is improved, but the safe becomes cumbersome and harder to carry
Solution Approach 1:
The patent replaces the conventional sturdy, heavy quadrilateral handle with a rounded, curved handle design. The handle features smooth curves and rounded edges rather than sharp angles and heavy construction. This curvilinear design maintains the handle's structural integrity and anti-theft capabilities while significantly reducing its weight and improving ergonomics for carrying.
Solution Approach 2:
The patent changes the physical parameters of the handle, specifically transitioning from a heavy, angular quadrilateral shape to a lighter, rounded shape with optimized dimensions. The handle's cross-sectional area and material distribution are adjusted to maintain strength-to-weight ratio, providing adequate security protection while reducing overall weight for easier portability.
3Reliability
If a conventional safe uses complex locking mechanisms for security, then security is improved, but the opening time for security checks increases
Solution Approach 1:
The patent implements preliminary action by positioning the latches and operating portion such that the unlocking operation is pre-configured for rapid execution. The latches are arranged to be simultaneously engaged and disengaged through a single rotational motion of the operating portion, eliminating the need for sequential unlocking steps. This preliminary arrangement of components enables quick opening when security checks are required.
Solution Approach 2:
The patent segments the locking mechanism into distinct functional components (first latch, second latch, operating portion) that can independently operate but are coordinated through a single user action. This segmentation allows each latch to be controlled separately for security purposes while being operable simultaneously for rapid opening, reducing the time required for security inspections.
4Ease of manufacture
If a conventional safe uses fixed locks that cannot be easily changed, then manufacturing simplicity is improved, but adaptability and key management flexibility are reduced
Solution Approach 1:
The patent implements a dynamic lock system where the operating portion and latches can be easily replaced or reconfigured. The connection between the operating portion and latches is designed to allow for simple removal and installation, enabling users to change locks, keys, or operating mechanisms as needed. This dynamic design provides adaptability for key management and security updates while maintaining manufacturing simplicity through standardized components.

AI summary
A conventional safe proper becomes useless when unable to be locked or unlocked, thereby causing a waste of resources. Locks capable of being locked/unlocked are provided to unfasten a common fastening member, so as to open a door or lid from the body, allow each lock to be freely mounted on and dismounted from a lock mounting portion, and dispose a false lock on each lock. An operating means of locking/unlocking any one of the locks is provided to enable persistent use of a common latch disposed at an identity opening of a safe proper.
