I started to design Lead Hearts because I believe that everything we use should be repairable, flexible and easy to customize so that it better suits the user.
My dog Penny chews her leashes (in England we call them leads) - she cuts right through the handle and then we have to throw away the rest of the lead, I think that is a waste - so I designed Lead Hearts, a system that can be used to make a repairable dog lead.
Lead Hearts are hard plastic, injection moulded blocks that clamp around a 10mm rope to hold it securely - when Penny, (or your dog) chews through the rope you simply unscrew the Lead Hearts and replace the rope.
10mm rope is easy to get and cheap to buy - in fact, old climbing rope which is almost free works really well with Lead Hearts.
We have tested Lead Hearts to make sure that the clamping system is solid, they stand up to 50Kg of pull with no problems, Penny is a big Bernese Mountain Dog, she pulls with a force of up to 20Kg so that is a good margin for safety .
And as a bonus Lead Hearts allow you to customize your a lead in a host of different ways.
You can make a really short lead for better control.
Or to make a super long lead with two clips for running with your dog.
Or to make up a multi dog lead with a single handle.
The Lead Heart at the top makes the handle really comfortable, it rests in the palm of your hand, the bottom one is easy to grab if you need to take your dog under closer control for some reason.
Lead Hearts come in loads of different colors and work with more or less any 10mm rope. We will offer all of our backers a choice of 6 different colors of Lead Heart and 4 different colors of rope, so with Lead Hearts you can make a dog lead that is perfect for you and your dog, you will love your lead made with Lead Hearts and it will last years (well most of it will). - PENNY !
Risks and challenges
Lead Hearts were designed using SolidWorks CAD and we have 3D printed 15 different versions for testing as we refined the design.
The final design has been tested for 'manufacturability' by an expert in plastic injection moulding. The mould is designed and we are ready to make it so that we can mass produce Lead Hearts.
As soon as the project is funded we will place the order for the mould and delivery of the parts will happen 6-8 weeks later.
The Rope, clips and bolts are already sourced so we are confident that we can deliver your rewards well within the 'lead time' (ho,ho) that we are quoting - if we get your support to help us pay for the tooling.Learn about accountability on Kickstarter
