Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In low light or low visibility settings, pedestrians and riders engaging in activities like walking, running, cycling, or using scooters are at risk of being overlooked by car and truck drivers, particularly in city environments, highlighting a need for enhanced safety measures to increase visibility.
Innovation Solution
Wearable systems with lights and a portable power source that cross over the torso, providing enhanced visibility by using flexible straps, LED lights, and optional reflective materials, designed to be comfortable and maneuverable during physical activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If wearable visibility systems with lights are used, then visibility is improved, but device complexity increases
Solution Approach 1:
The wearable visibility system divides the lighting function into multiple separate light sources distributed across the garment structure. Each light source can be independently controlled and positioned to illuminate different areas, achieving comprehensive visibility enhancement while keeping individual components simple and manageable
Solution Approach 2:
The wearable system integrates multiple functions into a single garment structure: visibility enhancement through lights, power source integration, and reflective material incorporation. This multi-functional approach reduces the need for separate safety devices while achieving comprehensive visibility improvement
2Duration of action of moving object
If portable power source is integrated into wearable system, then duration of action is improved, but weight of moving object increases
Solution Approach 1:
The power source is integrated into a flexible, thin garment structure that distributes weight across the wearer's body. The flexible strap design allows the power source to be positioned comfortably while maintaining low profile and minimal bulk, reducing the perceived weight burden
Solution Approach 2:
The wearable system uses flexible, adjustable straps that can be dynamically positioned and secured to distribute the weight of the power source across different body areas. This dynamic adjustment capability allows optimal weight distribution for comfort during various physical activities
3Ease of operation
If flexible straps are used for comfort, then ease of operation is improved, but strength of structure decreases
Solution Approach 1:
The straps are constructed from composite materials that combine flexibility for comfort with reinforced sections for structural strength. The composite structure allows the straps to be soft and adjustable for ease of wear while maintaining sufficient strength to support the weight of lights and power source during physical activities

AI summary
The present technology is directed to wearable visibility systems that can comprises a base strap, a light assembly carried directly or indirectly to the base strap, and a power source container carried by the base strap. The base strap has a front portion, a rear portion, and a shoulder portion between the front portion and the rear portion. The base strap is flexible and configured such that the shoulder portion is configured to conform to a shoulder of a person. The light assembly includes one or more light sources and is configured to extend along at least a portion of each of the front portion and rear portion of the base strap. The power source container is electrically coupled to the light assembly.
