B12-RX, a pioneer in health supplements, faced a common user challenge: the inconvenience and discomfort of clinic-based vitamin injections. They envisioned a home-use solution that would empower individuals. Their goal was to break down the barriers to consistent treatment through superior Self-Injector design. Partnering with LKK Design, they sought to combine medical necessity with consumer-grade usability, creating a device that was not only effective but also approachable.

The primary objective was to redefine the standards of Self-Injector design by creating a device that was intuitive, safe, and minimized pain. The key requirements were:

• An intuitive, 3-step user journey requiring no medical training.

• Integration of micro-needle technology for a nearly painless injection.

• An ergonomic and non-intimidating form factor.

• A secure mechanism for pre-filled syringes ensuring dose accuracy and sterility.

The ultimate goal was to leverage this innovative Self-Injector design to enhance user autonomy and establish B12-RX as a leader in the home-healthcare market.

LKK Design executed a comprehensive development process, where every stage was meticulously planned to optimize the Self-Injector design for manufacturing, functionality, and user experience.

Industrial Design

Our Self-Injector design process began with deep user empathy. We tackled anxiety and complexity by creating a product that felt more like a consumer electronic device than a medical tool. The form features soft, rounded contours for a comfortable and secure grip. A minimalist aesthetic with a single, well-defined button makes operation simple and foolproof, central to our user-centric Self-Injector design philosophy.

Mechanical Engineering Design

The mechanical Self-Injector design is where the promise of "nearly painless" was engineered. We developed a proprietary mechanism centered on an ultra-fine micro-needle to minimize skin penetration force. A precision spring and damping system were calibrated to ensure consistent drug delivery speed and accurate dosage. The internal structure was designed for a secure, click-in fit for the pre-filled syringe, a critical aspect of the Self-Injector design that guarantees safety and reliability.

Prototyping and Testing

We rapidly iterated our Self-Injector design through functional prototypes. Rigorous testing validated dose accuracy, ergonomic comfort, and most importantly, pain reduction. User trials provided direct feedback on the activation mechanism and injection feel, allowing us to refine the Self-Injector design to a level where over 90% of users reported a significant reduction in discomfort.

Mold Development

Translating the final Self-Injector design into manufacturable components required high-precision mold engineering. We developed complex injection molds, using advanced software simulation to predict and perfect the plastic flow. This step was crucial to ensure that every produced part of our Self-Injector design met strict standards for dimensional accuracy, surface quality, and structural integrity.

Mass Production

For mass production, our Self-Injector design was executed using medical-grade materials. We established a robust quality control system where every device was tested for critical functions, including needle safety, button actuation, and dose precision. This ensured that the high standards of our initial Self-Injector design were faithfully replicated in every unit shipped, enabling B12-RX to scale with confidence.

This project stands as a testament to LKK Design's holistic approach to Self-Injector design. The successful product transformed user experience, leading to high adherence and satisfaction. For B12-RX, our expert Self-Injector design became a key market differentiator, driving commercial success and solidifying their brand as an innovator. It demonstrates how strategic Self-Injector design can create category-leading products that merge technical excellence with human-centered design.
