LED Turn-Signal Jacket With Sequential Arm Arrow Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety apparel for motorcyclists and cyclists lacks effective turn signal indicators, leading to reduced visibility and increased risk of accidents, especially in low-light conditions.
Innovation Solution
A modified jacket with integrated LED lights on the arms, front, back, and shoulders, allowing for independent activation of turn signals via buttons on the sleeves, and featuring sequential lighting from shoulder to wrist with an arrowhead at the base to indicate intended turns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional motorcycles, bicycles and non-enclosed vehicles are used without integrated lighting systems, then the vehicle structure remains simple and cost-effective, but visibility to other drivers and pedestrians is poor especially at night or in low light conditions
Solution Approach 1:
The patent combines multiple lighting functions (turn signals, brake lights, head lights) into a single integrated garment worn by the rider. The LED lights are embedded in the fabric of the jacket, merging the lighting system with the protective clothing rather than adding separate mounting components to the vehicle.
Solution Approach 2:
The garment serves multiple functions simultaneously: it provides turn indication through arrow-shaped LED patterns, acts as a reflective safety vest for general visibility, and can function as a brake light indicator. This multi-functional design eliminates the need for separate signaling devices.
2Illumination intensity
If multi-light helmets are used to improve visibility, then other motorists and pedestrians can see the rider more easily, but the display becomes confusing and makes it difficult to decode the vehicle operator's intended movements
Solution Approach 1:
The patent uses distinct arrow-shaped LED patterns positioned on specific locations of the garment (shoulders, arms, back) to convey directional information. Each arrow points in the direction of the intended turn, providing localized visual cues that are spatially organized and easily decoded by observers.
Solution Approach 2:
The system uses different colors of LED lights to indicate different functions: green arrows for turn indication, red lights for brake signals, and white or yellow for head lights. This color-coding system provides intuitive visual differentiation of the rider's intended actions.
3Loss of information
If existing safety apparel is used without turn signal indicators, then the garment design remains simple, but the wearer's intended turning direction cannot be effectively communicated to other motorists and pedestrians
Solution Approach 1:
The turn indication system is segmented into multiple independent LED modules distributed across the garment surface. Arrow-shaped LED patterns are positioned on the shoulders and arms, with each segment capable of independent activation to indicate different turning directions (left, right, straight).
Solution Approach 2:
The garment acts as an intermediary carrier that translates the rider's hand signals or controller inputs into visible LED patterns on the back and sides of the garment, making the intended turn direction visible to observers who may not see the rider's hands or face.
Applied Scientific Principles
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 jacket significantly enhances the visibility of the wearer's intended turns to other motorists and pedestrians, reducing the likelihood of accidents and improving safety by providing a clear and easily understandable turn indication system.
Implementation Method 1
a modified garment or jacket to be worn by, for example, a motorcycle driver, and featuring integrated LED lights on its arms, front, back, shoulder and other surface areas
Data Source
AI summary
This present application discloses a turn direction indicating jacket having a plurality of directional indicators independently actuatable via a switch and a portable power supply. The invention illuminates the lights in sequential fashion from the wearer's shoulder to his or her wrist with an arrowhead at the base, there ensuring that other motorists and pedestrians alike are aware of the wearer's presence in traffic and the wearer's intended traffic movement.
