Innovation Solution
A liftable lighting device with a control assembly, a lamp holder, a lamp body, a first lamp wire assembly, a second lamp wire assembly, a power connection mechanism, and a wire winding mechanism, where the power connection mechanism includes power connection rings and a plate electrode with an elastic sheet group, allowing the lamp body to remain lit and controllable during lifting and at various positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lighting device is made liftable to enable easy cleaning and maintenance, then the ease of operation is improved, but the device can only be powered up at a specific operation position and cannot be lit during lifting
Solution Approach 1:
The patent applies the dynamics principle by making the power connection structure dynamic rather than fixed. The wire winding mechanism allows the lamp holder to move vertically while the elastic sheet group maintains continuous electrical contact with the power connection rings throughout the lifting range. This dynamic connection enables the lighting device to be powered and lit at any position during lifting, not just at a specific operation position, thereby resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The patent changes the parameter of electrical connection from static to dynamic by introducing elastic sheets that can deform and maintain contact during movement. The elastic sheet group's ability to stretch and compress allows continuous electrical connection as the lamp holder moves up and down, enabling lighting functionality at variable positions while maintaining the liftable design for easy maintenance.
2Device complexity
If a fixed power connection structure is used, then the device complexity is reduced, but the lamp holder cannot be lifted while maintaining electrical connection
Solution Approach 1:
The patent uses flexible thin films (elastic sheets) to create a power connection structure that can deform during lifting. The elastic sheet group acts as a flexible conductor that maintains electrical contact between the moving lamp holder and the fixed power connection rings. This flexible connection enables lifting capability while avoiding the need for complex sliding contacts or rotary connectors, thus resolving the contradiction between device complexity and lifting capability.
Solution Approach 2:
The elastic sheet group serves as an intermediary element between the fixed power connection rings and the moving lamp holder. This intermediary component absorbs the mechanical stress of lifting while maintaining continuous electrical connection, simplifying the overall power transmission system compared to direct rigid connections or complex mechanical contacts.

AI summary
A liftable lighting device includes a lamp holder, a lamp body, first and second lamp wire assemblies, a power connection mechanism, and a wire winding mechanism rotatably provided on the lamp holder. The first lamp wire assembly has a first end wound on the wire winding mechanism, and a second end extending away from the lamp holder, with the lamp body suspended thereto. The power connection mechanism includes power connection rings fixedly arranged relative to the lamp holder, and a plate electrode, which has elastic sheet group(s) and is connected to and can rotate with the wire winding mechanism. A control assembly is provided on the lamp holder. The second lamp wire assembly is electrically connected to the power connection rings and the control assembly. The elastic sheet group is electrically connected to the first end of the first lamp wire assembly, and slidably abuts against the power connection rings.
