A new drill motor redesign and rebuild from scratch.

The motive for the project was to make the Husqvarna's small drill motor business profitable. We've been asked to replace the old products that they had quality issues with, by new machines that have been developped by R&D and proved to be very reliable and powerful. The challenges were the very fast time to market restriction, and the need to work around the available package to not add complexity and involve more R&D work than necessary. The success criteria was an easy to assemble machine, with a design that integrates all sealing surfaces and seals available to keep the same performances. The machine was unveiled at the "world of concrete" expo of Las Vegas in January 2020.

My role as an industrial design lead has been to deliver a design that fits the Husqvarna DNA around a very restricted package. The project was mainly driven by mechanical restriction and manufacturability constraint, I therfore acted as a tampon between our R&D and our project management that wanted the product as fast as possible on the market. The biggest challenge was to be able to deliver a strong design without changing any single screw position nor sealing surface while keeping the air flow and cooling proprietaries already achieved in the R&D prototype.

Trustworthy attitude.

The lines of the machine communicate dynamism and compactness. Yet the machine looks robust. The choice of material such as the complete aluminium casing provides an extra premium feeling of quality and durability. All this is aimed to make that product a reliable choice for our customer.

From set up to result in no time.


Lightweight, compactness and durability were the key attributes when designing Husqvarna DM 400. But most importantly the machine needed to be easy to set up and use. The drill motor is the central part of a full drilling system where all of the components work together perfectly. Therefore our product has been build to be quickly snapped on and off the column to allow users changing position whenever he needs.

Setup

The design of the machine has been grandly driven from usability perspective. Flat surfaces on top of machine, size and shape of the handle for holding from anywhere as well as the feet design and snapping connection with the drill stand connector. The purposeful design allows work close to walls and corners.

Redesigned to withstand the toughest environment, the machine put the effort on the durability. The servicing is an important factor for those products which get rough headling on daily basis. The design was thought through to allows the machine to be quite easy to open and service.

Designing the little sister.

The handheld project started soon after the stand mount drill. This new machine obviously had to take cues from the other one. Again the challenge was to take over the lines with technical constraints and manufacturability issues.

Versus

You could think this project was easier as it could have been a simple "copy/paste" from the older sister project. Nevertheless even if the lines & design direction were already define, I still faced several challenges when it came to ergonomy and working out the handle part.

The initial handle design from engeneering was taken over from competition. I was time efficient and was proven to be reliable. But design wise it was far from Husqvarna DNA and ergonomy perspective.

ProcessMeeting

We had to play with too many technical constraints. It prevented us to have it exactly as my initial design, but at the end, we managed to have a product with a much better integrated handle than the competition. The handle feels more comfortable and seems like a continuity of the machine.

DM 400 is designed for rough handling and heavy drilling jobs, but it is also very easy to handle regardless of working conditions. It is really reliable work horse, built to make the operator proud of his work.
