Nyutveckling av hopfällbar kvistsåg

Sammanfattning

This Master Thesis has been carried out as a new product development project in collaboration

with G-Man Tools AB located in Edsbyn. The purpose of the project was to construct a new

pruning saw there the blade is integrateble in the handle, thus a foldable pruning saw.

The work has been performed on the occasion of G-Man Tools AB wanted to improve their

product range by creating a saw that complement their range of quality saws. They have a similar

product today, but they do not manufacture this product by them selves and it is not directly

targeted against garden use, which is a disadvantage when it is one of their major markets.

Even though almost the entire chain from the requirements of the users to drawings has been

taken into consideration, emphasizes has been put on generating ideas. However the first thing

that was carried out was to establish a productspecifikation from interviews with users and the

company’s experience. Next an extensive generation of ideas started where studies of other

products, workshops and different kreativitymetodes where carried out among other things. The

most promising ideas where further developed, evaluated and sorted out until only one concept

remained. This concept went under even further development and several different prototypes

were manufactured to detect faults and areas of improvements but also to hear what the users

thought of it.

The result is a foldable pruning saw with a belt clip. The saw with a button catch on the side of

the handle locks the blade folded as well as unfolded. The design follows G-Mans latest pruning

saw and the blade is modified after there existing manufacturing process. The handle has been

developed in consideration of both function and ergonomics. With the help of the belt clip one of

today’s problems is solved with this concept, namely the opening of the saw with one hand. This

ought to give the product an obvious advantage towards other products that don’t have this

feature.
