Magnetic Light Reflector Coating for Durable Mixed Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting devices for creating soft light, such as reflectors and soft boxes, are prone to breakage and damage due to their lightweight construction and lack durability, and are not designed to support additional lighting equipment or create mixed lighting effects efficiently.
Innovation Solution
A lighting reflector system composed of a metallic substrate with a reflective coating and magnetic mounts, allowing for the attachment of auxiliary devices like diffractors and lighting units, which can create mixed lighting effects and support additional equipment, while being durable and easily assembled/disassembled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If lightweight materials such as polymers and fabrics are used for reflectors, then the reflector is easy to transport and reposition, but the reflector is prone to breakage and surface damage
Solution Approach 1:
The patent uses a composite structure combining a rigid metallic substrate (steel or aluminum) with a flexible reflective fabric coating. The metallic substrate provides structural strength and durability while the fabric coating maintains the reflective properties and flexibility needed for operation. This composite approach resolves the contradiction by integrating the advantages of both material types.
Solution Approach 2:
The reflective fabric is stretched across a rigid wireframe or metallic substrate to create a flexible yet durable reflector surface. The thin film fabric provides the necessary reflectivity while the underlying rigid structure ensures durability and resistance to breakage, allowing the reflector to be both easy to handle and highly reliable.
2Ease of operation
If lightweight materials are used for reflectors, then the reflector is portable and collapsible, but the reflector cannot support additional lighting equipment
Solution Approach 1:
The rigid metallic substrate provides a strong foundation that can support additional lighting equipment while maintaining the overall portability of the reflector system. The metallic framework can bear the weight of auxiliary devices without compromising the ease of setup and transport.
Solution Approach 2:
The metallic substrate serves multiple functions: it provides structural support for the reflective surface, acts as a mounting platform for auxiliary lighting equipment, and maintains the collapsible framework for portability. This multi-functionality resolves the contradiction by making the reflector both portable and capable of supporting additional equipment.
3Reliability
If a rigid metallic substrate is used for the reflector, then the reflector is durable and can support additional equipment, but the reflector is more difficult to transport and reposition
Solution Approach 1:
The reflector is divided into modular components including a collapsible wireframe or metallic substrate that can be disassembled into smaller sections. This segmentation allows the durable metallic structure to be easily transported and repositioned by breaking it down into manageable pieces while maintaining its structural integrity when assembled.
Solution Approach 2:
The flexible reflective fabric coating on the metallic substrate allows the rigid structure to be collapsed and repositioned more easily. The fabric's flexibility enables the reflector to be compacted into a smaller form factor for transport while the underlying metallic substrate maintains its durability and strength when in use.
4Ease of operation
If a collapsible wireframe structure is used for the reflector, then the reflector is portable and easy to store, but the reflector lacks durability and is prone to breakage
Solution Approach 1:
The patent replaces the traditional collapsible wireframe with a rigid metallic substrate that maintains its structural integrity. The metallic material provides inherent durability and resistance to breakage while still allowing for collapsible design elements that enable portability and easy storage when disassembled.
Solution Approach 2:
The flexible reflective fabric stretched across the metallic substrate creates a durable yet collapsible structure. The fabric's flexibility allows the reflector to be collapsed for storage while the rigid metallic backing ensures durability and resistance to breakage during use.

AI summary
A light reflector includes a reflector body that is opaque and has a front surface. The light reflector further includes a coating applied to the front surface of the reflector body. The coating is configured to reflect and diffuse light from one or more light sources. One or more of the light reflector body or the coating comprises a ferromagnetic material. While a single reflector body can be used, optionally two or more light reflectors can be combined using, for example, magnetic forces to form a single light reflector unit having two or more light reflectors.
