Adjustable Door Lock Block for Universal Frame Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking devices face challenges in ensuring secure closure and preventing unauthorized access while allowing easy operation for skilled individuals, as they often require complex adjustments and lack universal compatibility with different door and frame dimensions.
Innovation Solution
A door locking device featuring two opposite bodies with housing grooves for screws, one equipped with a wedge and spring means, and a lock block with actuation mechanisms, allowing for adjustable and secure engagement without modifying the frame structure, enabling stable opening and closing with enhanced security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lock blocks with different dimensions are provided to achieve correct engagement, then security and correct opening are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies parameter changes by making the lock block dimensions adjustable rather than fixed. The lock block can be positioned at different locations along the sliding direction within the engagement groove, allowing the same lock block to engage with different frame positions. This resolves the contradiction by providing multiple engagement configurations without requiring multiple lock blocks of different dimensions, thus maintaining security while reducing device complexity.
2Reliability
If lock blocks with different dimensions are provided to achieve correct engagement, then security and correct opening are improved, but manufacturing cost increases
Solution Approach 1:
The invention reduces manufacturing cost by using a single lock block that can be positioned at different locations along the sliding direction, rather than manufacturing multiple lock blocks with different dimensions. The adjustable positioning mechanism allows one component to replace several, thereby reducing material costs, manufacturing complexity, and assembly requirements while maintaining the same security level.
3Manufacturing precision
If frame modifications are required to define correct engagement area, then locking precision is improved, but adaptability decreases
Solution Approach 1:
The patent applies dynamics by providing a movable and adjustable lock block that can be positioned at different locations along the sliding direction within the engagement groove. This dynamic positioning capability allows the locking device to adapt to different door and frame configurations without requiring permanent modifications to the frame structure, thereby maintaining both locking precision and adaptability.
Solution Approach 2:
The invention enhances universality by designing a lock block that can engage with multiple positions on the frame through adjustable positioning. The same locking device can be used across different door and frame types without requiring frame modifications, making it a universal solution that works with various dimensions and configurations while maintaining precise engagement.
4Reliability
If complex adjustments are required for correct opening, then security is improved, but ease of operation decreases
Solution Approach 1:
The patent applies dynamics by incorporating a movable lock block that can be easily repositioned along the sliding direction within the engagement groove. This dynamic adjustment mechanism allows skilled individuals to operate the door easily by simply moving the lock block to the appropriate position, without requiring complex procedures or tools, thereby maintaining security while improving ease of operation for authorized users.
