Rotational Lamp Head With Modular Rotary Drive
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rotary lamps have complex structures that make them costly and difficult to maintain, requiring professional repair for light source replacement and limiting adaptability due to integrated transmission mechanisms and specific lamp designs, which results in a large and non-universal device.
Innovation Solution
A compact rotary lamp holder with a modular design that includes a housing, motor stator, rotating shaft, lamp cover bracket, and reduction transmission system, allowing for easy replacement of light sources and adaptability to standard lamps, featuring a lead wire post and current pickup base for interchangeable screw-type or bayonet-type lamp holders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmission mechanism is integrated with a specific lamp structure, then the rotary function is achieved, but the adaptability and universality of the lamp are reduced
Solution Approach 1:
The invention divides the rotary lamp system into separate functional modules: a universal rotary drive mechanism and a specific lamp structure. The rotary drive mechanism includes a motor, transmission components, and a rotating platform that can be detached and applied to different lamp types, while the lamp structure (shade, fixture body) remains independent. This segmentation allows the same rotary mechanism to be adapted to various lamp designs without redesigning the entire system.
Solution Approach 2:
The rotary drive mechanism is designed as a universal component that can be applied to multiple types of lamps including pendant lamps, chandeliers, and table lamps. The motor assembly with its transmission mechanism and rotating platform serves multiple functions: providing rotational motion, supporting different lamp weights through adjustable mounting, and enabling easy attachment/detachment of various lamp structures. This universal design eliminates the need for custom rotary mechanisms for each lamp type.
2Ease of operation
If the lamp is designed as a unitary closed type to allow rotation of the lamp cover, then the visual and display effect is improved, but the structural complexity increases and the light source replacement becomes difficult
Solution Approach 1:
The invention segments the lamp into serviceable modules where the light source socket and bulb are accessible from the stationary fixture body, while only the decorative lamp cover rotates on the adjustable platform. This separation allows users to easily replace light sources by simply removing the bulb from the socket without needing to disassemble the entire lamp or deal with rotating mechanical components. The rotary mechanism is isolated to its own compartment with independent mounting.
Solution Approach 2:
The rotary function is extracted as a separate, detachable module that can be independently serviced. The light source replacement function is taken out from the rotating mechanism and placed in the stationary fixture body, allowing these two functions to operate independently. Users can replace bulbs without interacting with the rotary mechanism, and the rotary mechanism can be adjusted or repaired without removing the light source assembly.
3Volume of moving object
If a conventional motor with staggered output shaft and rotational axis is used, then the motor function is achieved, but the device size and structural complexity increase
Solution Approach 1:
Instead of using a conventional motor configuration where the output shaft is staggered from the rotational axis, the invention inverts the approach by aligning the motor's rotational axis directly with the output shaft that drives the rotating platform. The motor is mounted with its axis perpendicular to the lamp cover, and the rotating platform rotates about the same axis, eliminating the need for additional transmission components to correct misalignment. This inverted configuration reduces both size and complexity.
Solution Approach 2:
The invention merges the motor's rotational axis with the rotational axis of the lamp cover, creating a unified rotation system. The motor housing and mounting structure are integrated with the rotating platform support, so that the motor's rotation directly drives the lamp cover rotation without requiring separate transmission shafts or angle correction mechanisms. This merging of axes eliminates unnecessary intermediate components and reduces overall device size.

AI summary
A rotary lamp holder comprising: a housing having a first longitudinal end and a second longitudinal end, the first longitudinal end of the housing having an opening; a motor stator disposed around the inner circumference of the housing; a rotating shaft located in the housing and rotatably mounted relative to the housing, the rotating shaft defining a cavity in communication with the opening of the first longitudinal end of the housing; a motor rotor fixed to the rotating shaft and coaxially disposed with the motor stator; a lamp cover bracket rotatably mounted relative to the housing and extending out of the first longitudinal end of the housing; and a reduction transmission system located in the housing and connected to the rotating shaft and the lamp cover bracket respectively. Since the modular rotary lamp holder according to the present invention is compacter in structure and smaller in size and can completely match any lamp holder and lamp cover in any standardized form, it can completely become a universal substitute for the lamp holder mounted on the ordinary lamps.
