Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting apparatuses are often large and bulky, making them difficult to move, and they lack adjustable illumination direction and orientation without repositioning the device, and they are not conveniently packable for storage.
Innovation Solution
A portable lighting apparatus with pivotably supported illumination devices that can be rotated and adjusted in direction and orientation, featuring a telescoping shaft assembly and foldable leg assembly, allowing for flexible deployment and compact storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the lighting apparatus is made large to illuminate large areas, then the illumination coverage is improved, but the portability and ease of movement deteriorates
Solution Approach 1:
The lighting apparatus is divided into multiple independent legs that can be folded together and a telescoping shaft assembly that can be collapsed. This segmentation allows the large illumination structure to be broken into compact components for easy transport while maintaining large coverage when deployed
Solution Approach 2:
The apparatus incorporates movable components including telescoping shafts for height adjustment and foldable legs for compact storage. These dynamic elements allow the structure to transition between a large deployed state for illumination and a compact folded state for portability
2Adaptability or versatility
If the illumination direction is fixed, then the device structure is simplified, but the adaptability to different lighting needs deteriorates
Solution Approach 1:
The illumination devices are mounted on pivotable supports that enable dynamic adjustment of lighting direction. This allows the apparatus to adapt to different illumination needs while maintaining a relatively simple overall structure through standardized pivot mechanisms
Solution Approach 2:
The pivotable illumination devices can be positioned to provide various lighting patterns and directions, making the single apparatus capable of serving multiple lighting scenarios and applications without requiring multiple specialized devices
3Reliability
If the lighting apparatus is made bulky to provide stable illumination, then the illumination stability is improved, but the ease of storage and transportation deteriorates
Solution Approach 1:
The telescoping shaft assembly allows the structure to collapse into a nested configuration where inner shafts are received within outer shafts, dramatically reducing storage volume while maintaining structural integrity and illumination stability when deployed
Solution Approach 2:
The foldable leg assembly divides the support structure into separable segments that can be collapsed together, reducing the overall volume for storage and transport while providing stable support when the apparatus is set up for illumination

AI summary
A lighting apparatus has an upper hub, a base, a lower hub, and a pair of illumination devices that are pivotably supported at the upper hub, with each illumination device being pivotable up and down towards each other, as well as being rotatable. A telescoping shaft assembly has an inner shaft and an outer shaft, with the inner shaft telescopically received inside the outer shaft, the inner shaft having an upper end that is secured to the upper hub, and the outer shaft having a lower end that is secured to the base. A plurality of legs are connected to the lower hub and the base for pivoting motion therebetween.
