Floor-Mounted Door Lock Wedge Mechanism for Forced Entry Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door locks do not effectively prevent unauthorized entry into rooms, especially in emergency situations, as they lack a secure mechanism to prevent forced entry through the door.
Innovation Solution
A door lock system comprising a base, a wedge, and two pins that interact with the floor to secure the door in place, utilizing a magnetic field to bias the pins for easy engagement and storage, providing enhanced stability and immobility against unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional door lock is used, then the door can be locked, but it cannot effectively prevent forced entry or transform the room into a safe space during emergencies
Solution Approach 1:
The door lock system is divided into separate functional components: a base that interfaces with the door, a wedge that interfaces with the floor, and pins that connect them. This segmentation allows each component to perform its specific function optimally - the base provides mounting, the wedge provides mechanical advantage for forcing the door shut, and the pins provide secure attachment to the floor, together creating a reliable safe room system
Solution Approach 2:
The door lock system is pre-positioned in the floor at strategic locations before an emergency occurs. The base is permanently mounted to the floor, and the pins are ready for immediate insertion. When an emergency occurs, users simply need to insert the pins through the base into the floor and engage the wedge, transforming the room into a safe space within seconds without requiring complex assembly or significant effort
2Reliability
If a door lock system with pins and base is used, then the door can be securely fastened to the floor, but the device becomes more complex
Solution Approach 1:
The door lock system merges multiple functions into a single integrated device. The base combines mounting features, pin receptacles, and wedge engagement mechanisms. The pins serve dual purposes as both structural connectors and positioning elements. The wedge combines door forcing capability with locking function. This merging reduces the number of separate components needed while maintaining reliable door-to-floor securing capability
Solution Approach 2:
The door lock base is designed as a universal component that can be mounted in various floor configurations and works with different door types. The pins can be inserted at different angles and positions to accommodate various floor materials and door orientations. The wedge can engage with different floor surfaces. This multi-functionality allows a single device design to provide reliable securing across diverse installation scenarios without requiring multiple specialized components
3Ease of operation
If the door lock is designed to be quickly deployable, then it can be easily operated during emergencies, but it may lack stability and immobility
Solution Approach 1:
The base is pre-perforated with holes at optimal positions and angles for pin insertion, and the wedge is pre-positioned in the base. This preliminary preparation allows users to quickly deploy the system during emergencies by simply inserting the pins into the pre-positioned holes and engaging the wedge, achieving rapid deployment without compromising the stability of the final installed configuration
Solution Approach 2:
The pin insertion holes in the base are strategically positioned at locations that maximize structural stability and resistance to dislodgment forces. The holes are placed to create optimal leverage points and distribution of mechanical loads. The wedge is positioned to engage with floor structures that provide maximum anchoring strength. This local optimization of hole positions and component placement ensures quick deployment while maintaining high stability and immobility

Function Achieved in This Case
The door lock system transforms a room into a safe space by securely fastening the door to the floor, preventing unauthorized entry and enhancing occupant safety during emergencies with minimal effort, thus averting potential injuries or fatalities.
Implementation Method 1
The magnet imparts a magnetic field above the base engaging end to selectively bias the pins to the base

AI summary
A door lock has a base, a wedge, and two pins. The base has an engaging end that has two holes and is wider than a base abutting end. The wedge extends upwardly from the. The two pins are configured to pass through the base holes and apertures in a floor surface to secure the base to the floor surface. An outermost edge of each of the base holes is laterally outside opposite sides of the wedge. In another embodiment, a door lock includes a base, a wedge, two pins, and a magnet. The base has an engaging end has two holes and is wider than a base abutting end. The pins are configured to pass through the base holes and apertures in the floor surface to temporarily secure the base to the floor surface. The magnet selectively biases the pins to the base when the base is not engaged.
