Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Installing and replacing light bulbs, especially in hard-to-reach locations, is cumbersome due to the need for rotating them multiple turns to engage threaded or bayonet-style couplings.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded or bayonet-style couplings are used to secure light bulbs to sockets, then the connection is secure and reliable, but the installation and removal process becomes cumbersome and time-consuming, especially in hard-to-reach locations
Solution Approach 1:
The patent replaces the traditional mechanical threaded or bayonet-style coupling system with a magnetic coupling system. The magnetic adapters use magnetic attraction forces to secure the light bulb to the socket, eliminating the need for manual rotation and mechanical threading. This substitution maintains secure connection (reliability) while dramatically simplifying the installation and removal process (ease of operation), especially in hard-to-reach locations.
Solution Approach 2:
The patent changes the fundamental coupling parameter from mechanical interlocking (threads, slots, and pins) to magnetic field interaction. By introducing magnetic fields as the coupling mechanism, the system achieves both secure attachment and ease of operation. The magnetic force can be easily overcome by simple pulling motion, making bulb replacement convenient while maintaining reliable connection during operation.
2Reliability
If multiple turns of rotation are required to engage threaded couplings, then the connection is secure, but the installation time and effort increase significantly
Solution Approach 1:
The patent replaces the time-consuming mechanical rotation process with a simple magnetic attraction process. The magnetic adapters automatically align and secure the light bulb to the socket through magnetic force, eliminating the need for multiple rotational turns. This reduces installation time from potentially minutes to seconds, while maintaining secure connection through the magnetic coupling mechanism.
3Device complexity
If conventional coupling systems are used, then the structure remains simple, but the usability and convenience deteriorate in difficult-to-reach locations
Solution Approach 1:
The patent introduces magnetic coupling mechanisms that dramatically improve usability in hard-to-reach locations while adding only moderate complexity to the overall system. The magnetic adapters can be easily attached to standard light bulb bases and sockets, and the magnetic attraction provides secure holding without requiring precise alignment or manual manipulation in difficult-to-reach areas. The simplicity of the magnetic interaction outweighs the added complexity of the adapter components.

AI summary
A system and method is provided for easily and securely coupling objects together. In some examples, a coupling mechanism enables a user to install, remove, or replace conventional light bulbs (116) in conventional light bulb sockets (114), without the need to rotate the light bulb (116) several revolutions. A coupling mechanism uses a first adapter (112) threaded onto a conventional light bulb (116) and a second adapter (110) threaded onto a conventional light bulb socket (114). The first and second adapters (112, 110) use a combination of mechanical and magnetic coupling techniques to secure the light bulb (116) to the socket (114).
