Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hands-free lighting devices, such as lighted headgear, often compromise on lighting direction or visibility due to the placement and orientation of light sources, which can be cumbersome and distract from the primary task at hand.
Innovation Solution
The integration of LEDs and power modules within the brim of lighted hats, utilizing various configurations like recessed LEDs, light transmissive materials, and optical fibers to direct light forwardly while maintaining a traditional appearance, and employing renewable energy sources like solar or kinetic energy for power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light sources are mounted to headgear for hands-free lighting, then hands-free illumination is achieved, but the lighting direction and visibility are compromised due to placement and orientation constraints
Solution Approach 1:
The lighted headgear divides the illumination function into separate directional components: forward-facing LEDs for task illumination and outward-facing LEDs for visibility. This segmentation allows each light source to be optimized for its specific function without compromising the other, resolving the contradiction between hands-free operation and lighting direction control.
Solution Approach 2:
Different portions of the headgear are equipped with light sources having different orientations and functions. The front of the hat receives forward-directed LEDs for task lighting, while the sides or back receive outward-directed LEDs for visibility. This local differentiation of quality enables simultaneous optimization of both illumination direction and visibility without compromising hands-free operation.
2Illumination intensity
If conventional light sources are used in headgear, then illumination is provided, but the device becomes cumbersome and distracting from the primary task
Solution Approach 1:
The patent replaces traditional mechanical flashlight systems with integrated LED arrays mounted directly on the headgear. This substitution eliminates the need for separate handheld devices, reducing mechanical complexity and user burden while maintaining effective illumination. The LEDs are powered by integrated battery compartments and control circuits, further reducing device complexity.
Solution Approach 2:
The patent merges the illumination function with the headgear structure itself, integrating light sources, power supply, and control mechanisms into a single unified device. This consolidation eliminates the need for separate flashlights or lighting equipment, reducing overall device complexity and user burden while providing effective hands-free illumination.
3Reliability
If light sources are oriented outwardly for visibility, then visibility is improved, but task illumination in the field of view is reduced
Solution Approach 1:
The headgear employs separate light sources for different functions: outward-oriented LEDs for visibility and forward-oriented LEDs for task illumination. This segmentation allows each function to be optimized independently, with visibility LEDs positioned and oriented to maximize observer detection while task illumination LEDs are positioned to optimize field-of-view lighting without interfering with each other's performance.
