Details
In collaboration with Atlas Copco, I undertook the project to develop a new solution for the heavy electrical angle grinder sector, which the company sought to expand their business into.
The project involved a complete redesign of Atlas Copco's pneumatic angle grinder, LSV 39. The result is a powerful electric angle grinder with an ergonomic handle, enhanced safety features, and a robust construction. The redesigned grinder offers improved efficiency and has the potential to reduce the industry's total carbon dioxide output, surpassing existing competitors in the market.

background
Cause
The new EU Green Deal directives highlight the importance for companies to adopt environmentally-friendly practices in their operations. According to the UK Department of Industrial Strategy, the current diesel-driven compressor systems used in pneumatic solutions account for approximately 10% of the overall energy consumption in the industry. This results in the release of around 3100 kt of CO2 into the atmosphere annually, incurring a cost of approximately 512 million euros per year. These figures emphasize the significance of transitioning towards more sustainable and electrified alternatives.
Change
In a research paper published by the US Department of Energy Efficiency, it is suggested that companies operating in the heavy industry tool sector can achieve significant energy and cost savings by transitioning from pneumatic solutions to electrified alternatives. According to the findings, making this switch could result in potential savings of up to 1.1 kWh of energy and 95 euros per tool per year. These findings further highlight the economic and environmental benefits of adopting electric-powered tools in the industry.

Conclusions
As a class, we collaborated to disassemble a competitor model by Hilti. This allowed us to analyze the components and identify any "dead space" within the tool. We also examined if any components could be rearranged or replaced to optimize the design. A key finding was the potential to save valuable space by replacing the old brush motor with a brushless alternative. By relocating the motor to the far end of the tool, a new gripping area emerged closer to the front, which aligns with the preferred grip position for most operators. This reconfiguration improves ergonomics and user comfort, addressing a significant usability concern.

“angle grinders got to work and be safe to use”

Disc quick release
The LSV-39E improves safety and efficiency with its quick lock system for disc replacement, reducing interruptions and promoting a smoother grinding experience.
Secure cable lock
The LSV 39-E has a secure reverse thread-lock system for easy cable replacement, reducing downtime and costs while enabling one cable to work with multiple tools.
Vibration warning lamp
Daily angle grinder use can lead to significant health risks, mainly vibration damage due to high-pressure operation. LSV-39 E includes a vibration warning lamp, subtly illuminating when excessive force is applied to reduce operator stress and prevent nerve damage like Raynaud's phenomenon.
