Recessed Lock Frame Structure to Block Carded Latch Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door and window lock systems are vulnerable to unauthorized access through simple methods, such as using flexible cards or sheets to manipulate the latch, and existing security enhancements either project from the frame, causing accidents or are complex and costly.
Innovation Solution
A lock frame with a recessed interposition means that deploys to block unauthorized access by integrating into the door or frame, using a resilient mechanism activated by the door's closing motion, and includes grooves and flared ends to prevent card manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional accessories project from the frame to prevent card access, then security is improved, but the risk of accidents and damage increases
Solution Approach 1:
The anti-carding element is nested within a recess of the frame, specifically within a cavity formed between the outer face of the reinforcement plate and the inner face of the frame. This nesting approach allows the security element to be concealed rather than projecting outward, preventing both card manipulation and accidental contact while maintaining its security function.
Solution Approach 2:
The reinforcement plate acts as an intermediary component that creates a recess structure. By positioning the anti-carding element within this recess formed by the reinforcement plate, the design mediates between the need for security and the need to avoid harmful effects, allowing the security element to be effective without projecting from the frame surface.
2Reliability
If automated latch immobilization systems are used, then security is improved, but installation complexity and cost increase
Solution Approach 1:
The anti-carding element is passively activated by the door closing motion itself. As the door closes, the movement automatically causes the anti-carding element to rotate into its blocking position, preventing card insertion without requiring any external power source, control system, or complex installation infrastructure.
Solution Approach 2:
The anti-carding element transitions from a static component to a dynamic one that rotates automatically with door movement. This dynamic behavior allows the element to be in different positions (retracted during opening, blocking during closing) without requiring complex control mechanisms, simplifying the overall system while maintaining security.
