Solution Overview
Problem
Existing lighting setups in video, film, and television studios face challenges with reflectors, requiring multiple tripods and labor-intensive setups to manage light absorption and reflection, leading to significant material, space, and time expenditures.
Innovation Solution
A combination device that integrates a shielding flag with a reflector, using a tripod adapter to reduce the number of tripods needed and simplify setup, allowing for flexible positioning and adjustment of reflectors and flags.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If multiple separate tripods are used to support shielding flags around reflectors, then light management effectiveness is improved, but material expenditure and setup complexity increase significantly
Solution Approach 1:
The patent combines multiple separate shielding flags and their supporting tripods into a single integrated reflector device. The shielding structure is merged with the reflector body, eliminating the need for separate flag tripods while maintaining effective stray light control around the reflector.
Solution Approach 2:
The integrated reflector device performs multiple functions simultaneously: it provides the primary reflecting surface for light direction, incorporates shielding structures to control stray light, and includes positioning mechanisms for adjustable orientation. This multi-functionality replaces what previously required multiple separate devices.
2Object-affected harmful factors
If separate shielding flags are positioned around reflectors, then stray light is effectively blocked, but labor expenditure and setup time increase
Solution Approach 1:
The shielding structures are integrated into the reflector device as a unified assembly. This merging allows the entire unit including shielding elements to be positioned and adjusted as one component, dramatically reducing the time required compared to manually setting up multiple separate flags and their tripods.
Solution Approach 2:
The integrated reflector device incorporates adjustable mechanisms that allow dynamic repositioning of the entire assembly including shielding elements. This enables quick adaptation to different lighting conditions without the labor-intensive process of reconfiguring multiple separate components.
3Object-affected harmful factors
If multiple separate tripods and flags are used for each reflector, then complete light coverage is achieved, but space requirements and storage needs increase
Solution Approach 1:
By integrating the shielding structures directly into the reflector device, the patent eliminates the space required for multiple separate flag tripods. The compact integrated design occupies significantly less studio space while maintaining complete light coverage control through the built-in shielding elements.
4Object-affected harmful factors
If separately mounted shielding flags are used for each reflector position, then precise light control is achieved, but adaptability to different scenes decreases due to setup complexity
Solution Approach 1:
The integrated reflector device incorporates adjustable mechanisms that allow dynamic repositioning of the reflector surface and shielding structures. This enables precise light control for different scene requirements while maintaining high adaptability, as the entire assembly can be quickly reconfigured without the complexity of managing multiple separate components.
Solution Approach 2:
The versatile integrated design allows the same device to adapt to various lighting scenarios through its adjustable reflector surface and built-in shielding. This multi-functionality provides precise light control across different scenes without requiring multiple specialized setups, enhancing both precision and adaptability.

Function Achieved in This Case
Reduces material, space, and labor requirements while enabling efficient light management with fewer tripods, allowing for quick adaptation to different lighting conditions and reflection needs.
Implementation Method 1
the light from at least one spotlight is often directed onto at least one reflector positioned separately from the spotlight
Implementation Method 2
the skilled person in the prior art resorts to light-absorbing flags or banners that are set up or hung separately on all sides of the reflector

AI summary
The invention relates to a shielding flag device for combination with a reflector device. The reflector device is a flat structure (1) with a front side (2) and a rear side (3). The front side (2) is light-reflecting. The rear side (3) is provided with a rail device (4), which is designed such that a coupling device (5, 36), which is also provided and adapted to the rail device (4), can engage with the rail device in a lockable manner such that a location of the rail device (4) relative to the coupling device (5, 36) is adjustably variable in the longitudinal direction of the rail device (4) and the coupling device (5, 36) can be locked in the rail device (4) in a plurality of different positions with respect to the longitudinal direction of the rail device (4). The coupling device (5, 36) is provided to detachably fasten the flat structure (1) provided with the rail device (4) to a stand device (6, 7, 41, 44) and/or to a suspension device and is designed accordingly. The coupling device (5, 36) is designed so as to serve as the base for a shielding flag (11) stretched around the coupling device. As a special embodiment of a coupling device (5) or as part of a special coupling device (36), a stand adapter has a cylindrical portion (31) with at least two blind hole openings (32, 33, 34, 35), each of which protruding into the cylindrical portion (31) transversely to the longitudinal direction, being offset from one another in the circumferential direction of the cylindrical portion (31) and being suitable to receive a rod (12, 13, 14, 15) so that, with the aid of said rods (12, 13, 14, 15), the shielding flag (11) can then be stretched around the stand adapter.
