Problem
The replacement of lampshades in ceiling fans with integrated lighting is cumbersome for non-professionals due to the need to disconnect and reconnect electrode wires, making it inconvenient and difficult.
Innovation Solution
A lampshade structure with contact electrodes and elastic contact members that allow for easy connection and disconnection to an external power source through arc-shaped grooves, guided by guide posts and elastic contact members for precise alignment and secure locking, enabling quick assembly and disassembly without wire separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode wire is separated from the power wire for lampshade replacement, then the electrical connection is maintained, but the replacement operation becomes cumbersome and difficult for non-professionals
Solution Approach 1:
The invention divides the electrical connection system into separate modular components: a male connector fixed to the power wire and a female connector integrated with the lampshade. This segmentation allows the lampshade to be replaced independently without handling wire separations, as the female connector simply detaches from and reattaches to the male connector through a simple insertion motion.
Solution Approach 2:
The invention introduces connector components as intermediaries between the power wire and the lampshade. The male and female connectors serve as mediating elements that facilitate electrical connection without requiring direct wire-to-wire connections, thereby simplifying the replacement process while maintaining reliable electrical contact.
2Reliability
If the lampshade structure uses traditional wire connection methods, then electrical connection is achieved, but the device complexity increases for non-professional users
Solution Approach 1:
The invention employs simple, inexpensive connector components that can be easily manufactured and replaced. The male and female connectors are designed as basic electrical contact elements without complex mechanisms, making the overall system simple despite the modular approach. This simplicity reduces the perceived complexity for non-professional users while maintaining reliable electrical connections.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates simple and precise installation and removal of lampshades, ensuring secure electrical connections and reducing the complexity of replacing lampshades in ceiling fans with integrated lighting.
Implementation Method 1
A plurality of elastic contact members are elastically located at the bottom of the lamp holder... the elastic contact members are elastically pushed to exert a downward pressure applied on the top of the insulating plate
Implementation Method 2
The two contact electrodes are simultaneously moved along the corresponding arc-shaped grooves to contact the electrically-conductive elements, thereby supplying power to the circuit board

AI summary
A lampshade structure includes a lampshade housing and a base. A circuit board is accommodated in an accommodation room of the lampshade housing. The circuit board is connected to two contact electrodes. The base has a lamp holder and a lamp disk. The lamp holder has two arc-shaped grooves for insertion of the contact electrodes. The arc-shaped grooves each have a large-diameter end and a small-diameter end. An electrically-conductive element connected to an external power source is embedded in the small-diameter end. During installation, a guide post in the accommodation cavity room is moved along a guide groove on the outer peripheral wall of the lamp disk, and each contact electrode is energized by contacting the corresponding electrically-conductive element after sliding the guide post into place, so as to achieve quick installation and disassembly.
