DT-309A Torch
There is no space in the current torch to increase the size of the battery. The case and carabiner need to be redesigned to allow for this and a more ergonomic winding handle.
Cross-sectional area must be kept the same to avoid compromising ergonomics & one-handed operation.
The materials used in the current torch are functional but, together with the design, feel cheap and generic.
Re-designing the outer shell to be compatible with a textured mould would produce a superior surface finish and alleviate the need for external ribs.
A comprehensive LCA shows...
Battery capacity has been increased by 350%
This dramatically improves runtime, with battery cost only increasing from 24p to 78p (500 units).
