Lock Assembly Baffle Structure for Debris-Resistant Tamper Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locking systems are vulnerable to tampering due to debris being deposited within the housing, compromising their security.
Innovation Solution
A lock system comprising a cover, lock assembly, and baffle, where the baffle's unique cross-sectional dimensions and movable engagement with the lock mechanism and cover inhibit the intrusion of debris, creating a barrier that prevents unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the lock assembly housing is open and accessible, then the lock mechanism can be installed and maintained, but debris can be deposited within the housing compromising security
Solution Approach 1:
The baffle acts as an intermediary component between the lock mechanism and the external environment. It includes a first aperture that allows the lock mechanism to be inserted during installation, and a second aperture that is smaller than the lock mechanism's cross-sectional dimension, preventing debris from entering while allowing the lock mechanism to pass through during installation
Solution Approach 2:
The baffle is segmented into multiple functional apertures: a first aperture for installation purposes that is larger than the lock mechanism, and a second aperture for operational purposes that is smaller than the lock mechanism. This segmentation allows the same component to serve both installation and protection functions
2Object-affected harmful factors
If a protective barrier is added to prevent debris entry, then security is improved, but device complexity increases
Solution Approach 1:
The baffle serves multiple functions simultaneously: it acts as a protective barrier preventing debris entry through the smaller second aperture, while also serving as an installation guide for the lock mechanism through the larger first aperture. This multi-functionality reduces the need for additional separate components
Solution Approach 2:
The protective barrier function and the installation guide function are merged into a single baffle component. The baffle combines the debris prevention feature with the installation facilitation feature, eliminating the need for separate protective covers and installation guides

AI summary
A lock system includes a cover, a lock assembly, and a baffle. The cover includes a first aperture defining a first cross-sectional dimension. The lock assembly includes a lock mechanism defining a second cross-sectional dimension. The baffle includes a base and at least one leg. The base includes a second aperture defining a third cross-sectional dimension smaller than the first cross-sectional dimension and larger than the second cross-sectional dimension. In an assembled configuration, the base engages the cover, the at least one leg engages the lock assembly, and the lock mechanism is disposed within the first aperture and the second aperture.
