Pivoting Tripod Light Assembly for Portable Area Illumination
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 inadequate for illuminating larger areas.
Innovation Solution
A tripod light design featuring a collapsible support assembly with a pivotable frame, a battery receptacle, and a handle, allowing the light to be easily transported in a collapsed state and quickly deployed for effective illumination with adjustable legs for stability and balanced weight distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If larger lights are used to provide sufficient illumination, then illumination intensity is improved, but ease of operation deteriorates due to cumbersome transportation
Solution Approach 1:
The support assembly is divided into multiple legs (first leg, second leg, third leg) that can be independently positioned and adjusted. This segmentation allows the light to provide stable support for adequate illumination while the legs can be collapsed together for compact transportation, resolving the contradiction between illumination capability and ease of transport.
Solution Approach 2:
The support assembly transitions between static deployed positions (providing stable illumination) and dynamic collapsed positions (enabling easy transport). The ability to pivot and rotate legs between extended and retracted states allows the system to adapt between these two operational modes, resolving the contradiction between illumination stability and transportation convenience.
2Ease of operation
If smaller lights are used for easy transportation, then ease of operation is improved, but illumination intensity deteriorates
Solution Approach 1:
The second and third legs are nested within or alongside the first leg when collapsed, creating a compact configuration for easy transportation. When deployed, the legs extend to provide stable support for sufficient illumination, thus resolving the contradiction between compact transport and adequate illumination support.
3Stability of the object's composition
If the support assembly is extended for stability, then stability is improved, but volume increases making it harder to transport
Solution Approach 1:
The support assembly is segmented into multiple adjustable legs that can be independently positioned. When deployed, the legs spread out to provide stable support; when collapsed, they nest together to minimize volume, resolving the contradiction between stability and compact volume for transportation.
Solution Approach 2:
The legs utilize rotational movement about non-parallel, non-colinear axes to transition between extended (stable) and collapsed (compact) configurations. This multi-dimensional movement allows the support assembly to achieve stability in the deployed state while minimizing volume in the transported state, resolving the contradiction between stability and volume.

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.
