Lighting Softbox Angle Adjustment Device Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighting softbox angle adjustment devices are cumbersome and difficult to transport due to their long length, which exceeds the capacity of an ordinary sedan.
Innovation Solution
The angle adjustment device is designed to be disassembled into two connecting rods, allowing for a shorter overall length that can be easily transported in a regular sedan. This is achieved through a detachable design featuring a rotary crank, inclined crank, rotary transmission assembly, and inclined transmission assembly, which enable axial rotation and inclination adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the long rod is designed with a length greater than 3 meters to increase the effective irradiation range of the lighting softbox, then the irradiation range is improved, but the device becomes difficult to transport by an ordinary sedan
Solution Approach 1:
The long rod is divided into two separate connecting rods (first connecting rod and second connecting rod) that can be disassembled from each other. Each rod has a manageable length that can fit in an ordinary sedan, while when assembled together they provide the full length needed for extended irradiation range. The disassembly and assembly mechanisms include matching structures with positioning holes and positioning pins that enable easy connection and separation.
2Area of moving object
If the long rod is designed to be greater than 3 meters in length, then the effective irradiation range is increased, but the device complexity increases due to additional transmission mechanisms
Solution Approach 1:
The transmission mechanism is segmented into two identical sets, each located on one of the two connecting rods. Each set includes a rotary crank, inclined crank, rotary transmission assembly, and inclined transmission assembly. This segmentation allows the complex transmission functionality to be distributed across two simpler, identical modules rather than one large complex mechanism, making the overall system more manageable and easier to manufacture.
3Area of moving object
If the long rod is designed with greater than 3 meters length, then the irradiation coverage is improved, but the ease of operation deteriorates due to difficulty in handling and transporting
Solution Approach 1:
The device is segmented into two separate connecting rods that can be independently handled and transported. When not in use, the rods can be disassembled and stored separately, making them easy to fit in an ordinary sedan and simple to transport. When needed, they can be quickly assembled together to restore the full-length configuration for extended irradiation coverage.
Solution Approach 2:
The first inner tube is positioned inside the first outer tube, and the first inner rod is positioned inside the first inner tube. This nested arrangement allows the components to be compact when disassembled, further reducing the space required for storage and transport while maintaining the full extended length when assembled for operation.
