Project Title - Smart Suspension Load Backpack.

What is your product?

The revolutionary backpack boasts a sophisticated suspension mechanism designed to effectively alleviate the strain generated by the arduous task of running or walking with a heavy load. This cutting-edge technology diminishes the dynamic load exerted on the user's body, ensuring a more comfortable and effortless experience during physical activities.

Moreover, this exceptional bag is equipped with a myriad of advanced electronics, providing an array of convenient features. Integrated temperature, humidity, and pressure sensors deliver real-time data, allowing users to precisely monitor environmental conditions. Furthermore, the inclusion of a blood oxygen calculator empowers individuals to assess their physiological well-being while on the move.

The bag includes a robust 5000mAh power source to enhance its practicality, facilitating on-the-go charging for various devices. Users can effortlessly connect to a dedicated mobile application, seamlessly accessing the wealth of sensor data in real time.

Problem Statement

Backpacks are the preferred choice for travelers due to their convenience and ease of carrying. Even trekking enthusiasts, known as trekkers, rely on large backpacks to accommodate their needs during expeditions. Additionally, armed forces utilize these bags to transport heavy loads efficiently.

However, the act of walking or running while carrying such substantial weight imposes a considerable dynamic load on the human body. This excessive load can potentially inflict severe damage on various body parts, including the back, shoulders, legs, knees, and other vulnerable areas.

School bags typically weigh around 4 kg when comparing different types of backpacks, while trekking or big traveling backpacks can reach up to 11 kg. In contrast, members of the armed forces often carry an immense load of approximately 30-35 kg. One can only imagine the tremendous impact and strain this dynamic force places on the users' bodies.

It is imperative to acknowledge the potential risks associated with carrying heavy loads and take appropriate precautions to minimize the adverse effects on the human physique.

Who’s done it before

Hoverglide, a renowned company in the industry, has successfully pioneered the development of these innovative bags. Their relentless pursuit of excellence is evident through their numerous filed patents. The ingenious implementation of bungee cords within their design enables seamless and flexible motion transfer. The elastic nature of these bungee cords allows for the absorption of dynamic loads, facilitating vertical movement in both upward and downward directions.

Dedicated to ensuring exceptional quality, Hoverglide invested considerable time and resources into extensive research and rigorous testing. Their unwavering commitment has yielded remarkable results, with an impressive reduction of up to 86% in the generation of dynamic loads.

Hoverglide's ground-breaking accomplishments serve as a testament to its commitment to revolutionizing the industry. Through their inventive solutions and unwavering dedication, they have established themselves as trailblazers, setting new standards for ergonomic design and load management in the backpacking realm.

Presently, they offer a selection of two distinct models, each varying in size, and the price range for these bags falls between 550 and 600 USD.

A patent has been filed for an alternative design, and the team is presently engaged in developing the design depicted in the following illustration.

My design and Modifications

Before going forward with modifcations it is very important for me to learn the already existing mechnism by developing its basic prototyope.

Last time we planned it to make it using bungee cord, but we didnt able to find suitable vendors which can provide customize bungee cord. so this time we moved to the use of springs as it is very easy to find and manufacture customize springs.

Components used for the project.

To develope a first prototype, we need few mechanical components which can be availble in the market, Fabrication with 3D printing and Laser cutting technology and also few electronic components.

Mechnaical components

Steel Rods.

Used steel rods with different height and diameter to make frame for the mechinsm.

Linear Ball bearnings.

Used for linear ball bearnings with 10mm inner diameter for smooth motion of the bag.

Springs.

Purchased a customized springs for 10-12 kg load.

Clamps.

Few clamps will require for mounting and fixing position of the spring.

Digital Fabrication

3D printing Components

In-order to generate prototype we require lots of customize parts for manufacturing, and 3D Printing is the most effective way to design and manufacture such customize things.

I am planning to Manufacture Frames, clamps, electronics envolope using 3D Printing.

Laser cutting Technology.

I require 2-3 flat plates of acrylic material in a specific size and dimensions and i will use laser cutting machine to cut those parts.

Fabric Material

old Unsed bag

Used old unused nag for this prototype, further i have planning to manufacture customize bag for the project.

Foam

Will use foam for safety point of view.

Electronics Component

DHT Sensor

A DHT (Digital Humidity and Temperature) sensor is a device used to measure both humidity and temperature levels in the environment. It provides accurate and reliable readings, typically using a capacitive humidity sensor and a thermistor for temperature measurement. DHT sensors are commonly used in various applications such as weather monitoring, HVAC systems, and indoor climate control.

Oxygen Sensor

A blood oxygen sensor is a device that measures the oxygen saturation level in a person's blood. It typically uses a non-invasive method, such as a fingertip clip or a wristband, to measure the amount of oxygen carried by red blood cells. This information can help monitor respiratory health and detect potential issues.

Xiao Esp 32 c3 Controller.

The Xiao ESP32-C3 is a compact development board based on the ESP32-C3 microcontroller, designed by Espressif Systems. It features a powerful 32-bit Xtensa LX7 core, Wi-Fi connectivity, and low power consumption. The board is equipped with GPIO pins, ADC channels, UART, I2C, and SPI interfaces, making it suitable for various IoT applications.
