Pivoting Tripod Light Assembly for Brightness and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable area lights often face a trade-off between sufficient illumination and ease of transportation, as larger lights provide adequate lighting but are cumbersome, while smaller lights lack sufficient brightness and are easy to carry but not effective for illuminating larger areas without permanent fixtures.
Innovation Solution
A tripod light design featuring a collapsible support assembly with a pivotable frame, allowing the light to be easily deployed and stowed, and a battery receptacle for power, enabling effective illumination with balanced portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If larger lights are used to provide sufficient illumination, then illumination intensity is improved, but device portability deteriorates
Solution Approach 1:
The light device is divided into separable components: a compact light engine unit and a collapsible tripod support structure. This segmentation allows the illumination component to be small and portable while the support structure provides stability when deployed, resolving the contradiction between sufficient illumination and portability.
Solution Approach 2:
The tripod support assembly incorporates collapsible legs with pivot joints that allow the structure to transition between a compact stored configuration and an extended deployed configuration. This dynamic transformation enables the device to be portable during transport while providing stable support for adequate illumination during use.
2Illumination intensity
If larger lights are used to illuminate areas without permanent fixtures, then illumination intensity is improved, but device complexity increases
Solution Approach 1:
The device separates the illumination system from the support system, allowing each to be optimized independently. The light engine remains simple and compact while the tripod support provides necessary stability, reducing overall device complexity while maintaining adequate illumination.
Solution Approach 2:
The collapsible tripod structure serves multiple functions: providing stable support for the light, enabling portable transport, and offering adjustable positioning. This multi-functionality reduces the need for additional specialized components, thereby simplifying the overall device structure.

AI summary
A tripod light includes a frame supporting a light assembly, and a support assembly coupled to the frame and configured to support the frame on a surface. The support assembly includes a first leg, a second leg, and a third leg. The support assembly is pivotable relative to the frame about a first axis between a stowed position in which the support assembly including the first leg, the second leg and the third leg is adjacent the frame, and a deployed position in which the support assembly including the first leg, the second leg, and the third leg extends away from the frame. Each of the second leg and the third leg is configured to rotate relative to the first leg about a second axis between a collapsed position and a respective extended position of the second leg and the third leg.
