Adapter Ejector Pin Safety Mechanism for Illuminating Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional illuminating devices lack safety protection, leading to potential electric shocks due to direct electrical connections during user misoperation.
Innovation Solution
An adapter with an ejector pin and operating member that blocks or releases the power supply connection, ensuring safe electrical engagement and disengagement, preventing accidental start-ups and electric shocks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the adapter uses direct electrical connection between conductive terminal and power supply module, then the device structure is simple and easy to operate, but user safety deteriorates due to potential electric shocks
Solution Approach 1:
The patent introduces an ejector pin as an intermediary component between the power supply module and the adapter. This ejector pin acts as a safety mediator that physically prevents direct electrical connection unless properly ejected, thereby reducing electric shock risk while maintaining ease of operation through a simple ejection action
Solution Approach 2:
The patent applies preliminary anti-action by using the ejector pin to block the connection interface before power supply. The ejector pin must be actively ejected to allow connection, creating a preliminary safety barrier that prevents accidental or misoperative direct connection, thus addressing the harmful factor before it can occur
2Object-affected harmful factors
If the adapter includes safety protection mechanisms like ejector pin, then user safety is improved, but device complexity increases
Solution Approach 1:
The patent segments the safety function from the main adapter body by using a separate, movable ejector pin component. This segmentation allows the safety mechanism to be added without fundamentally redesigning the entire adapter structure, minimizing the increase in device complexity while maintaining effectiveness
Solution Approach 2:
The ejector pin is designed as a dynamic component that can move between blocked and ejected positions. This dynamic design allows the safety mechanism to transition from an active blocking state to a passive allowed state, providing safety protection without requiring complex control systems or multiple components

AI summary
An adapter, a light source device employing the same, and an illuminating device employing the same are provided. The adapter includes a main body, an ejector pin movably connected with the main body, and an operating member disposed between the ejector pin and the main body. The main body includes: a power supply mounting part, a light source mounting part, and a conducting wire extended from the power supply mounting part to the light source mounting part. The ejector pin is operationally moved to a blocking position for preventing the power supply mounting part from being matched with the power supply module and a release position for releasing the power supply mounting part to be matched with the power supply module. The operating member is operationally moved on the main body to an ‘on’ position and an ‘off’ position.
