Removable Light Unit with Tripod Support for Mobile Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lighting devices are limited in their mobility, require electrical connections that restrict movement, are bulky for hand-carrying, and rely on batteries that may fail, necessitating constant replacement.
Innovation Solution
A mobile lighting device with a removable and rechargeable light unit that transforms into a tripod for height adjustment, incorporating a built-in power supply and storage, allowing for versatile positioning and easy recharging via electrical connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wired work light is used, then the light can be connected to electrical grid, but the user's movement is limited due to the power cord length
Solution Approach 1:
The lighting system is divided into separate functional modules: a portable light unit with integrated power supply and a separate support structure. This segmentation allows the light to be detached and positioned independently, eliminating the constraint of a power cord while maintaining reliable power delivery through the integrated battery system.
Solution Approach 2:
The power supply system is extracted from the external electrical grid dependency and integrated directly into the portable light unit. The battery-powered design removes the power cord constraint, enabling free movement while maintaining reliable operation through the self-contained power system.
2Ease of operation
If a battery-powered device with handle is used, then the device is compact and portable, but it can only be suspended and requires constant battery replacement
Solution Approach 1:
The support structure serves multiple functions: it acts as a tripod for height adjustment, a storage compartment for the light unit, and a positioning platform for various lighting configurations. This multi-functionality enables the system to adapt to different positioning requirements while maintaining portability.
Solution Approach 2:
The support structure includes adjustable components that can transform between different configurations (tripod mode, storage mode, suspended mode). This dynamic adaptability allows the system to switch between various positioning options based on operational needs while maintaining compact portability.
3Illumination intensity
If a device with telescopic pole is used, then the light can be positioned at height, but the device is too heavy and bulky to carry by hand
Solution Approach 1:
The system separates the heavy support structure (tripod) from the lightweight light unit. The light unit with its integrated power supply is compact and easy to carry, while the tripod provides the necessary height positioning when deployed. This segmentation reduces the weight of the portable component while maintaining the height capability through the separate support structure.
4Illumination intensity
If telescopic pole size relative to base unit is large, then height adjustment is possible, but it is difficult to position in tight corners
Solution Approach 1:
The support structure features collapsible legs that can be folded into a compact configuration for storage and tight spaces, then deployed into a full tripod configuration for height adjustment. This dynamic transformation allows the system to adapt its footprint size based on operational requirements, enabling positioning in both tight corners and open areas.
