Rotating Bulb Adaptor for Threaded and Bayonet Sockets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulb adaptors are limited in that they can only accommodate either threaded or bayonet bulbs, making them inconvenient to use when the corresponding type of bulb is not available.
Innovation Solution
A bulb adaptor with a rotating mechanism and dual connecting members that allows it to be used with both threaded and bayonet bulbs by switching between electrical contact positions, enabling secure connection and lighting of either type of bulb.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bulb adaptor is designed for a specific bulb type (threaded or bayonet), then the connection reliability for that bulb type is improved, but the adaptability to different bulb types deteriorates
Solution Approach 1:
The adaptor incorporates two separate connecting members (first connecting member with threaded structure and second connecting member with bayonet structure) within a single device, enabling it to accommodate both threaded bulbs and bayonet bulbs. The rotating mechanism allows switching between the two connecting members, making the adaptor universal for different bulb types while maintaining reliable connections for each type.
Solution Approach 2:
The rotating mechanism enables dynamic switching between the first connecting member and the second connecting member. By rotating the adaptor body, the user can bring either the threaded connecting member or the bayonet connecting member into the working position, allowing the adaptor to adapt its configuration based on the bulb type being installed.
2Device complexity
If a single adaptor design is used for both threaded and bayonet bulbs, then the device complexity is reduced, but the ease of operation deteriorates due to switching mechanisms
Solution Approach 1:
The rotating mechanism provides a simple dynamic switching action between the two connecting members. The user can easily rotate the adaptor body to bring the appropriate connecting member into position, making the switching operation intuitive and convenient rather than complex.

AI summary
A bulb adaptor is provided which includes a mounting housing, a rotating mechanism, a first connecting member and a second connecting member. The mounting is provided with threads. The first connecting member includes a convex first live contact part and two first metal connecting parts. The second connecting member includes a convex second live contact part, a neutral contact part and two second metal connecting parts. The second connecting member is arranged crosswise with the first connecting member. The rotating mechanism includes a rotating member and a convex part. The convex part has a first position and a second position. The first position is where the convex part is in electrical contact with the two first metal connecting parts, and the second position is where the convex part is in electrical contact with the two second metal connecting parts. The rotating member is slidably connected with the mounting housing.
