Job ID: 40162503

Budget: $750 – $1,500 USD

Smart Jersey Hardware Design Engineering Specifications
1. Product Overview
The smart jersey integrates LED technology to display dynamic light patterns controlled via a mobile app. This wearable technology is designed for sports, events, and outdoor activities, offering high visibility and a customizable light experience. The hardware must be lightweight, durable, and waterproof, ensuring comfort and seamless integration into the fabric of the jersey.
2. Key Features
LED System:
Type: Programmable RGB LED system.
Lumen Output: 800-1000 lumens to ensure adequate brightness for visibility in different lighting conditions.
Light Customization: The LED system should allow users to select or create dynamic light patterns, adjust brightness, and change colors via the mobile app.
Power Consumption: Efficient design to minimize energy consumption and maximize battery life.
Power Supply:
Battery Type: Rechargeable lithium-ion battery.
Battery Capacity: 150mAh, designed for 5-6 hours of use on a full charge.
Charging Port: Magnetic USB-C charging port to maintain waterproof integrity and ease of connection.
Charging Time: Optimized for quick recharging, ideally under 2 hours for a full charge.
Connectivity:
Bluetooth: Integrated Bluetooth Low Energy (BLE) chipset to allow for communication between the jersey and the user’s smartphone.
RF Chipset: For stable, long-range connectivity in large venues or crowded areas.
3. Durability & Protection
Waterproofing:
IP68 Rating: Full protection against dust and immersion in water up to 1.5 meters, ensuring the jersey can be worn in rain or washed without damaging the electronics.
Silicon Enclosure: The PCB and battery are sealed within a silicon casing, providing a waterproof barrier while maintaining flexibility and comfort.
Shock Resistance:
Impact-Resistant: The casing should be robust enough to withstand accidental drops or impacts without compromising the integrity of the internal components.
4. Attachment and Integration
Attachment System:
Modular Mounting System: The hardware must have built-in threads or modular slots for secure attachment to different parts of the jersey.
Flexibility: Design the attachment points to allow easy integration with various wearable products, such as life jackets, fanny packs, or backpacks, without compromising comfort.
User Comfort: The design must ensure the components are lightweight and ergonomically positioned to avoid discomfort or restricted movement.
5. User Interface & Interaction
Power Button:
A simple power button for turning the device on and off. It should also allow toggling through light patterns and colors.
LED Indicators: Small, discreet LEDs near the button to indicate the device’s charging status, power, and light pattern mode.
App Integration:
Mobile App Control: Users will control the LED patterns, color settings, and light animations via a dedicated mobile app. The app will allow for real-time control during events or performances.
Personalization: The app should allow users to set and save custom light sequences and patterns that can be synced with sports teams, events, or personal preferences.
6. Design & Form Factor
Dimensions:
The hardware should be compact, with the entire system fitting within a small, discreet module that can be seamlessly integrated into the fabric of the jersey.
Weight: The total weight of the module, including the PCB, battery, and casing, should not exceed 50 grams to ensure user comfort during wear.
Shape:
The shape of the module must be streamlined and low-profile, allowing the jersey to remain flexible and functional while housing the technology.
7. Environmental Considerations
Temperature Range:
The device should be able to operate between -20°C and 60°C to account for various environmental conditions.
Materials:
The external casing should be made of durable, UV-resistant plastic or silicone, ensuring it can withstand prolonged exposure to sunlight without degrading.
8. Assembly & Manufacturing
Modular Design:
The PCB, battery, LED system, and charging port should be modular for easy assembly and potential future upgrades or repairs.
Ease of Manufacturing: Components should be designed for mass production with cost-effective manufacturing processes in mind (e.g., injection molding, PCB assembly).
Waterproof Sealing:
Use high-quality seals around the USB-C charging port and between all sections of the casing to ensure water-tightness. Magnetic connectors should be designed to maintain strong connectivity while preventing water ingress.
9. Performance Metrics
Battery Life:
At least 5-6 hours of continuous operation at maximum brightness, with a standby time of several days when not in use.
LED Performance:
Capable of emitting 800-1000 lumens with consistent light output across the RGB spectrum.
The LED system should not suffer from significant color distortion or brightness drop-off over time.
App Latency:
The app should allow for real-time control with a maximum delay of 100ms between user input and LED response.
10. Testing & Validation
Waterproof Testing:
The design must undergo testing to ensure it meets the IP68 waterproof rating by submerging the module in water up to 1.5 meters for 30 minutes.
Shock Testing:
The device must be tested for durability by subjecting it to drop tests from 1.5 meters onto various surfaces.
Performance Testing:
The LED system should be tested for consistent brightness and color accuracy under various ambient lighting conditions.
The battery should be tested for charge retention, charging time, and expected longevity.
