Cordless
Power Drill
Fourth Year
10 Weeks
This final year design project tasked me to design a highly detailed and refined 18V Cordless Power Drill. We were told to choose a relevant brand, research the company and design a product that could slot seamlessly into their portfolio.
Manufacturing capabilities & confidence of internal component fit were key components of the brief, but the most important facet to consider was usability aka ergonomic fit of the drill. Through the following stages these aspects were considered and refined to create my final design, Borra.
Stage 1: Research
Initial research undertaken on Bahco's brand identity, other competitors [through visiting & testing products at a local B&Q] and technical requirements [through disassembling and investigating a current cordless combi drill].
Stage 2: Ideation
Ideation was broken down into each of the drill's key areas. Potential ideas based on form and function were sketched out, all of which tried to adhere to Bahco's current design trends on their latest products.
Stage 3: Concept Creation
Designs from the previous section were combined to create specific directions. From this, fully fledged drawings of the drills were formed to present to the client as distinct direction options.
2D and 3D models were created of each of these concepts to ensure they were realistic options from both an ergonomic and technical [confidence of fit] point of view. The client chose Concept C, with aspects of A to take forward for refinement.
Stage 4: Concept Refinement
Refinement included drawings to combine and refine aesthetic details, 3D prints to accurately decide upon handle form and multiple cardboard models for ergonomic and technical purposes.
​
After iterating through these mediums, a final design was created to be reproduced in CAD. Line drawings of the designed components were also produced to prove manufacturability.
Stage 5: CAD Model & 3D Print
From the final refined idea, the drawings were reproduced in Solidworks including internal components.
​
A full scale 3D print was created from the CAD model, including a removeable battery pack to simulate the real-life use of the product.
Stage 6: Final Design Visuals
To present the final concept, a webpage advertising the product, Borra, was created rather than individual boards. Key design features of the Borra are:
​
-
Ergonomic support loop around the trigger, which also provides user protection.
​
-
Bahco 'weave' grip pattern- synonymous with new Bahco products.
​
-
Redesigned buttons & switches- all intuitive to the action these require.
​
-
Bahco fish logo belt clip.
