Hidden Switch Lamp via Threaded Illumination Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LED lamps with visible switches on the base or outer surface are aesthetically unpleasing and difficult to place on flat surfaces, and resilient piece-based switches have a limited lifespan.
Innovation Solution
A lamp design featuring a hidden switch mechanism where the illumination assembly is secured to the lamp body via screw threads and projections, using lateral deposit technology for durable electrodes, allowing for manual control through clockwise and counterclockwise rotation to turn the lamp on and off.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an on/off switch is provided on the base or outer surface of the lamp body, then the lamp can be manually controlled, but the lamp cannot be placed on a flat surface or the appearance is aesthetically unpleasing
Solution Approach 1:
The switch mechanism is nested within the lamp body structure. The illumination assembly is inserted into the lamp body, and the switch function is integrated into the insertion/removal action itself, rather than having a separate switch component on the exterior surface.
Solution Approach 2:
The switch function is extracted from the traditional location (base or outer surface) and integrated into the illumination assembly itself. The act of inserting or removing the illumination assembly performs the switching function, eliminating the need for a visible external switch.
2Shape
If the on/off switch is provided in a cavity on the base, then the lamp can be placed on a flat surface, but it is difficult to manually move the on/off switch
Solution Approach 1:
The system performs the switching function automatically through the insertion and removal of the illumination assembly. The mechanical action of assembling or disassembling the lamp components itself activates or deactivates the light source, eliminating the need for a separate manual switch operation.
Solution Approach 2:
The switching function is merged with the assembly/disassembly action. The electrical connection is established or broken simultaneously with the mechanical insertion or removal of the illumination assembly, combining two functions into one action.
3Device complexity
If a resilient piece based switch is used in the lamp body, then the switch can be integrated internally, but the switch has a limited useful life
Solution Approach 1:
The resilient piece-based mechanical switch is replaced with a contactless electrical connection system. The illumination assembly contains electrodes that establish electrical contact with corresponding contacts in the lamp body through the screw connection, eliminating the need for resilient mechanical components with limited lifespans.
Solution Approach 2:
The switching mechanism transitions from a mechanical resilient piece system to an electrical contact system. The connection method changes from mechanical deflection of resilient pieces to direct electrical contact through threaded screw connections, fundamentally changing the operational parameters and extending service life.

AI summary
A lamp includes a lamp body; and an illumination assembly including a lamp shade assembly including a shade and a seat; and a lamp board. The seat is threadedly secured to the lamp body. The lamp board is secured to a lower end of the seat and laterally extends out of the seat. The lamp board serves as a bottom of the seat. The lamp board includes two first electrodes fastened on a bottom and a plurality of second electrodes adjacent to an edge. The first and second electrodes are electrically connected to positive and negative terminals of a control circuit of the lamp board respectively. The first and second electrodes are positive and negative terminals of a light source respectively. A clockwise rotation of the illumination assembly threadedly secures to the lamp body and turns on the light source.
