Solution Overview

Problem

Existing lighting apparatuses lack safety protection, posing a risk of electric shock due to direct user connection, as they do not have mechanisms to prevent misoperation.

Innovation Solution

An adaptor with a push-out part and operating component that blocks or releases the power supply mounting part, turning the conducting circuit on or off to prevent accidental activation, ensuring safe engagement with the power supply module.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the conducting terminal is directly electrically connected with the power supply module, then the lighting apparatus can be activated, but the user is likely to be subjected to an electric shock due to misoperation

Engineering Contradiction:
Improveease of activationVSAvoidelectric shock risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary mechanism (the operating component that controls the push-out part) between the user's action and the electrical connection. This intermediary ensures that electrical connection only occurs when the operating component is in the correct position, preventing direct accidental contact with live terminals while still allowing easy activation through the designated operating component.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent applies preliminary anti-action by designing the push-out part to automatically block the power supply mounting part from being engaged with the power supply module unless the operating component is properly positioned. This preliminary blocking action prevents misoperation before it can cause electric shock, while still allowing easy activation when the correct operating procedure is followed.

Inventive Principle:
Principle #9Preliminary anti-action

2Object-affected harmful factors

If a safety protection device is added to prevent electric shock, then user safety is improved, but the device complexity increases

Engineering Contradiction:
Improveelectric shock protectionVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges the safety protection function with the existing structural components. The push-out part and operating component are integrated into the adaptor's power supply mounting structure, combining the safety blocking function with the mechanical engagement mechanism. This merging approach provides electric shock protection without adding separate, complex safety devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements self-service safety protection where the operating component and push-out part automatically control the engagement state without requiring external control systems. The mechanism self-regulates to ensure safety - when the operating component is not in the correct position, the push-out part automatically blocks engagement, providing safety protection without complex external control.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If the push-out part blocks the power supply mounting part, then misoperation is prevented, but the ease of engagement is reduced

Engineering Contradiction:
Improvemisoperation preventionVSAvoidease of engagement
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the push-out part movable rather than fixed. The push-out part can dynamically switch between blocking and releasing states based on the position of the operating component. This dynamic design prevents misoperation when blocking is needed, while easily allowing engagement when the operating component is properly positioned, thus maintaining ease of operation.

Inventive Principle:
Principle #15Dynamics

AI summary

Embodiments of the present invention disclose an adaptor, a light source device using the adaptor and a lighting apparatus using the adaptor. The adaptor includes a main body, a push-out part, and an operating component. The main body includes: a power supply mounting part, a light source mounting part, and a conducting circuit extending from the power supply mounting part to the light source mounting part; the push-out part is operatively movable to a blocking position for blocking the power supply mounting part from being engaged with the power supply module, and a releasing position for releasing the power supply mounting part to be engaged with the power supply module; the operating component is operatively movable on the main body to an on-position and an off-position; when the power supply mounting part is engaged with the power supply module, by a resisting force from the power supply module, the push-out part moves to the releasing position and maintains in the releasing position, and the operating component moves to the on-position so as to turn on the conducting circuit; when the power supply mounting part is separated from the power supply module, the push-out part moves from the releasing position to the blocking position and meanwhile driving the operating component to move from the on-position to the off-position so as to turn off the conducting circuit. The embodiments of the present invention achieves driving the operating part to move from the on-position to the off-position to turn off the conducting circuit when there is no need of using the lighting apparatus, by moving the push-out part to the blocking position, thus preventing the user from activating the lighting apparatus due to misoperation and resulting in an electric shock, and improving the safety of the lighting apparatus.
