What it does
QDM SYS 1 (Quick Digital Measuring System) is a modular device for craft and construction professionals. It combines laser measurement, 3D scanning and smartphone calibration to provide layout planning, precise and visualize data to help reduce material waste.
Your inspiration
During my research on measurement tools, I observed that manual methods are still widely used in construction and craft. However, even small measurement errors can lead to material waste, and relying on paper records slows workflows and makes data harder to share. Modern laser measurement improve accuracy, reaching ±2 mm over 100 m. 3D scanning software also enables fast spatial capture and easier real data storing. After speaking with experts at Festtool, I saw the need for tools that are accurate, safe, digital, and easy to use. I began working with them to explore how these elements could be combined into a more efficient workflow.
How it works
QDM SYS 1 is a fast, digital measuring system consisting of a modular device and companion app. By using your smartphone to capture spatial layout and combining it with precise laser measurement, it delivers an intuitive workflow. To begin, you snap your phone onto the device using a magnetic pad, and press a button to connect Bluetooth. Then, scanning the room allows the app to automatically generate a 2D and 3D layout, giving you a clear spatial overview. A second button on the ergonomic handle activates the laser and a green LED guide for accurate calibration. The laser module rotates 180 degrees to measure from different heights and angles without needing to move the tool. During measurement, the app helps you hold the phone steady and level for optimal results. Unlike conventional workflows that require switching between separate apps and tools, QDM SYS 1 integrates everything into a seamless system. It detects your position and guides you step by step.
Design process
I began this project by analyzing workflow data and insights from Festool to understand user needs. Many construction professionals and craft workers expressed the need for a fast, simple, and accurate way to measure spaces. Through reviewing tools like Bosch, Magicplan, and Moasure, I identified two complementary technologies: 3D spatial capture and traditional laser measurement. These two technologies became the core of the proposed solution. In the concept phase, I realized that the interaction between digital and physical elements is key when introducing new tools. I focused my exploration on this, using sketches and models to test modular layouts while considering ergonomics and device stability. Early prototype testing showed that even when using digital tools, users preferred physical and visual feedback, such as trigger buttons and LED indicators. Based on this, I refined both the hardware and interface through multiple iterations. As a final step, I created a 3D-printed physical prototype and tested it with target users in realistic scenarios, assessing usability and overall user experience. Based on feedback, I refined details and developed a visual user journey to show how the system works in practice.
How it is different
QDM SYS 1 differs from existing tools in its focus on digital integration and accurate measurement experience. Many existing tools are complicated to use and involve switching between variable devices that don’t work smoothly together. In contrast, my design combines 3D spatial capture and laser measurement in a single system, bringing together the strengths of both methods. Compared to conventional workflows, this delivers a simpler and more intuitive experience. Craft and construction professionals can use it with no special training and receive real-time, precision 2D and 3D data, which improves both accuracy and efficiency.
Future plans
In the future, I plan to upgrade QDM SYS 1 in two areas. First, I will build technical partnerships with 3D capture software providers and continue working with Festool on hardware development. My goal is to achieve seamless integration between software and hardware. Second, I plan to test the system in real construction and craft environments to evaluate usability, calibration accuracy, and workflow integration. My final goal is to provide a measuring tool that supports professionals in daily works, making digital precision more accessible, efficient, and sustainable.
