Portable Neck Light with Adjustable LED Sources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lights do not provide adequate hands-free illumination and are not designed to fit comfortably around the neck, nor do they offer adjustable and removable light sources for specific task requirements.
Innovation Solution
A portable neck light with two LED light sources, each independently adjustable on a 70-degree axis, made of flexible ABS plastic, powered by alkaline or rechargeable batteries, and featuring a USB port and battery charge indicator, allowing for comfortable wear and removable functionality as a handheld light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If portable lights are designed to be hands-free, then user convenience is improved, but the device must be worn around the neck which may cause discomfort or poor fit
Solution Approach 1:
The neck member is constructed from flexible plastic material that can be bent and shaped to conform to different neck sizes and contours. This flexibility allows the device to adapt to various users without causing discomfort, while maintaining secure hands-free wearability.
Solution Approach 2:
The device incorporates adjustable parameters including the flexibility of the neck member material and the positioning of light sources that can be independently adjusted. These parameter changes enable customization of the fit and comfort level to suit different users and usage scenarios.
2Measurement precision
If light sources are made adjustable for specific task requirements, then lighting precision is improved, but device complexity increases
Solution Approach 1:
The lighting system is divided into multiple independent light sources positioned at different locations on the device. Each light source can be independently adjusted in direction and angle, allowing precise targeting of specific areas without requiring complex centralized control mechanisms.
Solution Approach 2:
The light sources are mounted on movable joints or hinges that allow dynamic adjustment of their orientation. This enables users to change the direction of illumination as needed for different tasks, providing adaptability without permanent complex mechanical structures.
3Adaptability or versatility
If light sources are made removable for handheld use, then versatility is improved, but connection reliability may deteriorate
Solution Approach 1:
The device is segmented into separable components with light sources that can be detached from the main body. This segmentation enables dual usage modes: wearable configuration for hands-free operation and handheld configuration for portable lighting, while maintaining reliable electrical connections through designed coupling mechanisms.
