Dual-Axis Lighting Head Drive With Compact Main Unit Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices for imaging devices require increased space for separate mechanisms to drive the head part in horizontal and vertical circular directions, complicating layout and inspection processes.
Innovation Solution
Integration of first and second motors and corresponding power transmission mechanisms within a single driving unit connecting the main unit and the head part, allowing independent horizontal and vertical pivoting without expanding the main unit's space, and enabling unified inspection of the bounce driving mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate driving units for horizontal and vertical circular directions are built in the main unit, then the head part can be driven in both directions, but the space for layout of the main unit increases
Solution Approach 1:
The patent combines both the horizontal circular driving mechanism and vertical circular driving mechanism into a single integrated driving unit. This driving unit connects the main unit and the proximal end of the head part, allowing both driving functions to be performed from one location rather than requiring separate mechanisms in the main unit, thereby reducing the layout space required.
Solution Approach 2:
The patent relocates the driving mechanisms from the main unit to a driving unit that operates at the connection interface between the main unit and head part. This spatial reorganization allows the driving functions to be performed in a different dimensional location, reducing the area requirement of the main unit while maintaining full driving capability.
2Adaptability or versatility
If separate driving units for horizontal and vertical circular directions are used, then both directions can be controlled, but inspection complexity increases due to multiple separate units
Solution Approach 1:
The patent merges the horizontal driving mechanism and vertical driving mechanism into a single integrated driving unit. This consolidation reduces the number of separate mechanisms from two to one, simplifying the overall device structure and making inspection easier while maintaining the ability to control bounce photography in multiple directions.
3Area of stationary object
If the driving unit is integrated with the main unit, then space is saved, but the driving mechanisms may interfere with other components
Solution Approach 1:
The patent extracts the driving mechanisms from the main unit and places them in a separate driving unit that connects the main unit and head part. This extraction isolates the driving mechanisms from other main unit components, preventing potential interference while maintaining space efficiency. The driving unit operates independently at the interface, avoiding conflicts with batteries, circuit boards, and other main unit elements.

AI summary
A lighting device is provided in which a head part is allowed to be driven relative to a main unit in a horizontal circular direction and in a vertical circular direction separately without the need for increasing a space for the layout of the main unit and the like. The lighting device of the present invention includes a driving unit (7) connecting a main unit (3) and a head part (6). The driving unit (7) includes first and second motors, a first power transmission mechanism that rotates the driving unit (7) in a horizontal circular direction (the direction of an arrow F) with the driving force of the first motor, and a second power transmission mechanism that rotates the driving unit (7) in a vertical circular direction (the direction of an arrow B) with the driving force of the second motor. With this configuration, the head part (6) is allowed to be driven relative to the main unit (3) in the horizontal circular direction and the vertical circular direction separately, without the need for increasing a space for the layout of the main unit (3) and the like.
