Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable lights do not provide adequate hands-free, adjustable, and versatile lighting solutions for users, particularly in situations requiring focused illumination, and often lack the ability to be comfortably worn around the neck or powered by rechargeable batteries.
Innovation Solution
A portable neck light with two independently adjustable LED light sources, powered by alkaline or rechargeable batteries, made of flexible ABS plastic, featuring a ratchet or ball joint mechanism for adjustable illumination and a USB port with charge indicator, allowing for comfortable wear and removable light sources for handheld use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If portable lights are made rigid for structural stability, then strength is improved, but comfort and flexibility for neck wear deteriorates
Solution Approach 1:
The patent applies flexible plastic material to the light housing and body, replacing traditional rigid materials. This allows the light to conform to the contours of the user's head and neck, providing comfort during wear while maintaining sufficient structural integrity through the engineered flexibility of the plastic components.
2Device complexity
If fixed light sources are used, then device complexity is reduced, but adaptability for different lighting needs deteriorates
Solution Approach 1:
The patent incorporates movable light sources that can be adjusted by the user to different positions and angles. This dynamic capability allows the light to adapt to various lighting needs and working conditions, while the adjustment mechanism is designed to be simple and intuitive, minimizing the increase in device complexity.
3Ease of operation
If rechargeable batteries are implemented, then ease of operation is improved, but device complexity and manufacturing difficulty increases
Solution Approach 1:
The patent implements rechargeable battery power sources with integrated charging circuits, allowing the device to recharge itself when connected to a power source. This eliminates the need for separate battery replacement operations and provides continuous operation capability, improving ease of use while the integrated design keeps manufacturing complexity manageable.
