Portable Worklight Collapsible Hinged Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting apparatus are often large and bulky, with fixed illumination direction, making them inconvenient to move and adjust, and they lack the ability to efficiently illuminate large areas without repositioning.
Innovation Solution
A portable worklight with a collapsible design featuring hingedly coupled side bodies and a pivotable base, allowing for adjustable illumination direction and orientation without moving the device, and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the portable worklight uses a fixed illumination direction design, then the structure is simple, but the illumination cannot be adjusted without moving the lighting apparatus
Solution Approach 1:
The patent applies the dynamics principle by making the illumination devices adjustable through hinged connections. The side bodies are hingedly coupled to the main body, allowing the illumination devices to be pivoted between different orientations. This dynamic adjustment capability enables the illumination direction to be changed without moving the entire lighting apparatus, resolving the contradiction between ease of operation and device complexity.
2Area of stationary object
If the portable worklight is designed to illuminate a large area, then the coverage is improved, but the device becomes large and bulky
Solution Approach 1:
The patent applies segmentation by dividing the lighting apparatus into multiple independent illumination devices distributed across different sides of the main body. Each illumination device can be independently adjusted through hinged connections, allowing the system to cover a large area when deployed while maintaining a compact form factor when collapsed for storage and transportation.
3Ease of operation
If the portable worklight is made collapsible for storage, then the portability is improved, but the illumination coverage may be reduced
Solution Approach 1:
The patent applies dynamics by designing a collapsible structure with hinged connections that allow the illumination devices to be positioned in different configurations. When collapsed for storage, the side bodies fold against the rear surface of the main body, creating a compact form. When deployed, the same hinged connections allow the side bodies to pivot away from the rear surface, extending the illumination coverage area. This dynamic transformation resolves the contradiction between storage convenience and illumination coverage.

AI summary
A portable worklight has a main body having a lower end, a left side, a right side, a front surface and a rear surface, with a first illumination device provided on the front surface. The worklight also has a left side body hingedly coupled to the left side and having a second illumination device, and a right side body hingedly coupled to the right side and having a third illumination device. A base is pivotably mounted to the lower end of the main body. The worklight can be configured in a deployed position and a storage position.
