Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable battery-powered lighting solutions for sports and outdoor activities are often heavy, lack versatility, and do not maintain constant brightness as the battery depletes, with limited recharging options and adjustable beam aim.
Innovation Solution
A lightweight, rechargeable battery-powered lighting device with a micro USB charging port, adjustable beam, and interchangeable mounting options for use on headbands, helmets, and bicycles, featuring a flexible power cable and pivot connection for beam adjustment, and dual LED emitters for different lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If existing portable lighting solutions use higher power batteries to increase beam brightness, then illumination intensity improves, but weight increases and duration of action decreases
Solution Approach 1:
The patent uses LED technology which fundamentally changes the illumination parameter efficiency. LEDs provide high luminous output per unit energy and weight compared to traditional incandescent bulbs, allowing bright illumination without proportionally increasing battery weight or power consumption
Solution Approach 2:
The lighting device is designed with multiple mounting options (headlamp clip, bicycle mount, handheld) and can function in different modes (constant brightness, dimmed for night vision preservation), making it universally applicable across different activities without requiring multiple separate devices
2Ease of operation
If existing lighting devices use non-rechargeable batteries to simplify power supply, then ease of operation improves, but loss of substance increases due to disposable battery waste
Solution Approach 1:
The patent implements a rechargeable battery system with a removable battery pack that can be recharged via USB connection. Instead of discarding depleted batteries, users can recharge them repeatedly, significantly reducing waste while maintaining operational simplicity through the convenient USB charging interface
Solution Approach 2:
The patent replaces the mechanical/chemical battery replacement system with an electrical recharging system using USB technology. This substitution eliminates the need to physically replace batteries and reduces material waste while maintaining ease of operation through standardized charging ports
3Device complexity
If existing headlamps use fixed mounting to simplify structure, then device complexity decreases, but adaptability worsens due to limited mounting options
Solution Approach 1:
The patent designs the headlamp with multiple interchangeable mounting accessories including a headband clip, bicycle handlebar mount, and handheld options. This allows a single device to serve multiple functions and be adapted to different activities without increasing the core device complexity
Solution Approach 2:
The mounting system is segmented into separate, interchangeable components rather than being integrated into a single fixed structure. Users can attach or detach different mounting accessories as needed, providing adaptability while keeping each individual mounting component relatively simple in design
4Device complexity
If existing lighting devices lack adjustable beam aim to simplify design, then device complexity decreases, but adaptability worsens for different activity requirements
Solution Approach 1:
The patent incorporates a pivotable lamp head that can be adjusted to different angles and positions. This dynamic adjustment capability allows the beam direction to be changed as needed for different activities or mounting positions, providing adaptability without requiring a complex multi-component adjustment mechanism

AI summary
A portable light apparatus includes a light housing with a light source and a separate battery case connected to the light housing with a cable. The light apparatus can be configured and used in several different ways: as a miner light or flashlight, with the light housing secured to an end of the battery case via a snap-in connection; as a bicycle light, with the battery case secured to a handlebar stem and the light housing secured to the handlebar or stem; a helmet light, with the battery case attached at the back of the helmet and the light housing at front; and as a headstrap light, with the light housing attached to the headstrap at a front position and the battery casing at a different position, preferably at rear. Clips, brackets and straps are included for adapting the light and battery case to the various purposes, without tools. Preferably the light housing is capable of pivoting on a base, so the user can adjust aim of the light beam.
