Slam Latch Cam Lock Adapter Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locks, such as fixed cam and dead-bolt locks, can be damaged when users slam doors or drawers shut, causing damage to the lock and the surrounding furniture.
Innovation Solution
A combination slam latch and cam lock adapter module that includes a housing with a mating end for engaging the lock's driving element, a retractable slam bolt with an inclined surface, and a resilient element to urge the slam bolt outward, along with retention elements to limit its travel, allowing for automatic relocking of the enclosure upon closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fixed cam locks or dead-bolt locks are used, then the lock provides secure closure, but the lock and furniture can be damaged when the door or drawer is slammed shut
Solution Approach 1:
The adapter module serves as an intermediary component between the lock and the drawer/door. It includes a slam latch element with a resilient element (spring) that absorbs the impact energy when the drawer is slammed shut, preventing direct transmission of harmful forces to the lock and furniture while still maintaining secure closure functionality
Solution Approach 2:
The resilient element (spring) is pre-installed in the adapter module to cushion against potential slamming forces before they reach the lock. This beforehand cushioning mechanism absorbs shock and prevents damage to both the lock and surrounding furniture when accidental slamming occurs
2Strength
If the lock is designed to be robust and damage-resistant, then the lock can withstand slamming forces, but the structural complexity and size of the lock increase
Solution Approach 1:
The system is segmented into separate functional components: the original lock remains simple and unchanged, while the adapter module contains the complex resilient element and slam latch mechanism. This segmentation allows the lock to stay structurally simple while the adapter provides the necessary strength and damage resistance
Solution Approach 2:
The adapter module acts as an intermediary that absorbs complex shock-absorbing mechanisms away from the simple lock body. The resilient element and retention elements in the adapter handle the complexity of withstanding slamming forces, while the lock itself remains structurally simple and easy to manufacture
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adapter module prevents damage to the lock and furniture by ensuring secure closure without slamming, allowing for repeated use without compromising the lock's integrity.
Implementation Method 1
such resilient element may comprise a pair of compression mounted springs
Implementation Method 2
a resilient element with one end thereof secured relative to such housing and with the other end thereof engaging such slam bolt for urging such slam bolt

AI summary
A self-contained combination latch and cam lock adapter module affixes to the rear of any lock (keyed or non-keyed) that has a requisite mating feature. The module is alignable in any of four positions (up, down, left, and right) on the back of the lock for latching in any installed position. The module allows a user to slam closed an associated door or drawer without having to rotate the lock into a locked position. The module retrofits in the field by removing and replacing an existing fixed cam. In one embodiment, a mating part is rotationally spring-loaded so that when the key or knob is turned and then released, the module automatically returns to its locked position, ready to be shut.
