Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ring lights are cumbersome and difficult to carry due to their continuous circular shape, limiting portability and versatility in various applications.
Innovation Solution
A collapsible radial light design featuring a hub with rotatable arms that can extend and fold, reducing size and weight, allowing for adjustable lighting patterns and easy portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a continuous circular ring light design is used, then lighting coverage and evenness are improved, but portability and ease of carrying deteriorate
Solution Approach 1:
The continuous circular ring light is divided into multiple discrete arms that can be independently positioned. Each arm extends radially from a central hub and can be rotated to different angular positions, allowing the lighting structure to be segmented into manageable sections that reduce overall weight and improve portability while maintaining effective lighting coverage when deployed.
Solution Approach 2:
The ring light transitions from a static continuous circular structure to a dynamic collapsible design where arms can be rotated between extended and folded positions. This dynamic capability allows the light to be easily collapsed into a compact form for portability and extended to a full circular configuration for optimal lighting coverage, resolving the contradiction between these two states.
2Volume of moving object
If a collapsible arm design is used, then portability and size reduction are improved, but structural complexity increases
Solution Approach 1:
The collapsible design incorporates rotational joints at the hub where each arm connects, enabling smooth transition between extended and folded positions. This dynamic mechanism allows compact storage when arms are folded while maintaining full functionality when extended, managing the balance between size reduction and structural complexity through controlled movement.
Solution Approach 2:
The ring light is divided into multiple independent arms that can be rotated and positioned separately. This segmentation allows each arm to be independently managed and positioned, simplifying the overall structural complexity by breaking down the large circular structure into smaller, more manageable components that can be collapsed individually.

AI summary
A light includes a hub and an arm extending radially outward from the hub. The arm includes a light source configured to emit light from the arm. The arm is rotatably connected to the hub such that the arm is configured to rotate about a longitudinal axis of the hub between an extended angular position and a folded angular position. The arm extends radially outward from the hub in a different radial direction in the extended angular position as compared to the folded angular position.
