Integrated LED Cap Brim Illumination for Continuous Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lighted headwear designs often have gaps or dark spots in their field of view, requiring users to adjust the headwear or move their head to achieve desired illumination, and they typically consist of multiple separate components that are bulky and aesthetically unpleasing, with issues during assembly and use.
Innovation Solution
A multiple light source cap device with integrated LEDs, an actuation switch mechanism, and adjustable brightness, where light sources project both forward and downward, providing a continuous wide range of illumination over 90° without separate fasteners or excessive adhesives, by embedding light sources within the brim of the cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate light sources are used to provide wide illumination coverage, then the field of view coverage is improved, but the device complexity and assembly difficulty increase due to multiple separate components
Solution Approach 1:
The patent integrates multiple light sources (first light source projecting forward, second light source projecting downward, and third light source projecting downward at a different angle) into a single cap device structure. This merging of multiple light sources into one integrated unit provides comprehensive field of view coverage while reducing device complexity compared to using completely separate lighting components.
Solution Approach 2:
The cap device serves multiple functions simultaneously: it provides forward illumination for viewing items ahead, downward illumination for reading and close-range activities, and integrated construction that eliminates the need for separate mounting components. This multi-functionality addresses both illumination coverage needs and assembly simplicity requirements.
2Reliability
If separate mounting components (fasteners, adhesives) are used to attach light sources to the brim, then the light sources can be securely mounted, but the aesthetic appearance deteriorates and assembly becomes more complex
Solution Approach 1:
The light sources are integrated directly into the brim structure itself rather than being attached as separate components. This integration eliminates the need for visible fasteners and adhesives, maintaining aesthetic appearance while ensuring secure mounting through the unified construction of the cap device.
3Device complexity
If a single fixed light source position is used, then the device complexity is reduced, but the illumination coverage is insufficient creating dark spots
Solution Approach 1:
The illumination system is segmented into multiple light sources with distinct functions: a first light source for forward projection, a second light source for downward projection, and a third light source for downward projection at a different angle. This segmentation eliminates dark spots and provides comprehensive coverage while maintaining integrated construction within the cap device.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a seamless and aesthetically pleasing continuous illumination from 0° to 90°, eliminating the need for separate components and adjustments, enhancing usability and appearance.
Implementation Method 1
The multiple light source cap device includes a first light source which is integral with the front edge of the brim and which projects light in a forward direction... In a preferred embodiment, the first light source is a light emitting diode.
Data Source
AI summary
A multiple light source cap device with short and long range lighting. The cap device includes a brim extending forwardly from a crown. A first light source is integral with a forward part of the brim, the first light source projecting light in a forward direction aligned with and projecting from the brim. A second light source in the brim projects light at a downward angle to the first light source forward direction. A third light source in the brim projects light at a downward angle from the second light source downward angle.
