Background

The original Shot Scope system was comprised of a wrist worn device in combination with a twenty club tags, one tag being inserted into the top of each golf club. The Club Sense system is able to record the user the exact point on the course where the ball was played, detect which club has been and the associated shot distance.

Shot Scope GPS combines this proven tracking technology with an integrated GPS range finder system which indicates the distance to the green on each hole as well as the position of difficult obstacles.

Our Approach

We were determined to address the challenge presented by the "antennae within a strap" challenge right from the start because if this could not be done properly the product could be compromised. The intent was always to over-mould the antenna, effectively a flexible circuit, with a soft but robust silicone however there were issues to be addressed. The flexible circuit would have to be inserted into a mould tool, held securely without warping, and withstand the tool and curing temperatures. i4’s engineers conceived a twin over-mould technique to address these concerns.

The Design

Whilst the product architecture was being developed, i4 were able to develop a series of appearance design options. The inclusion of a graphical screen and additional ‘mode’ button would give this product a different appearance over the initial Shot Scope, but i4 wanted to work within the spatial constraints to develop a product that would be both appealing and fit for purpose.

The appearance design was developed within the size constraints of the new PCB, into a form with features which streamline from the main housing down to the strap. Clever use of gloss, matt and textured areas are employed to underline the professional Shot Scope marketing message.

Tooling & Manufacturing Support

Right at the beginning of the project i4 identified a vendor capable of completing the over-moulding of the antenna within the strap. This collaboration allowed us to further develop the twin over-mould strategy. The vendor did comment that the approach was new to them, but were supportive throughout a prototype/early production phase.

As per our normal practice formal reports were generated at key stages to record and guide the parts to golden sample.

i4 became involved with Shot Scope’s preferred assembly house at an early stage in the product design stage, which meant that there were no surprises waiting in the wings!
