Solution Overview

Problem

Traditional door locks are often insecure and can be easily defeated, failing to effectively prevent unwanted or unauthorized entry into a room.

Innovation Solution

A door securing apparatus comprising a mounting member, a pivoting arm extension, and a door-contacting member, where the pivoting arm extension is secured to the mounting member with a pivot-securing member, allowing the door to be locked in a closed position by applying pressure to the door frame, preventing it from opening without removal of the pivot-securing member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional door locks are used, then the door can be locked, but they are insecure and can be easily defeated

Engineering Contradiction:
ImprovesecurityVSAvoidcomplexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The door securing apparatus is divided into distinct functional components: a mounting member for attachment to the door frame, a pivoting arm extension that provides the securing action, and a pivot-securing member that acts as the locking mechanism. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity and high security.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a secure locking mechanism is implemented, then unauthorized entry is prevented, but the device becomes more complex

Engineering Contradiction:
ImprovesecurityVSAvoidease of use
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The pivoting arm extension automatically engages with the door when the door is closed, and the pivot-securing member automatically locks into place without requiring manual intervention. The system secures itself through the natural closing motion of the door, eliminating the need for complex manual locking operations while maintaining high security.

Inventive Principle:
Principle #25Self-service

3Reliability

If the pivoting arm extension is secured to the mounting member, then the door is secured in closed position, but the door cannot be opened without removing the pivot-securing member

Engineering Contradiction:
ImprovesecurityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The pivoting arm extension is designed to be dynamically secured to the mounting member through the pivot-securing member, allowing it to pivot when the door closes and then lock into a fixed position. This dynamic-to-static transition provides secure locking while maintaining a simple mechanical structure without complex mechanisms.

Inventive Principle:
Principle #15Dynamics
