These concept sketches for the 5th generation Dolphin Torch were designed by Angelo Kotsis, designer at Design Resource, Crows Nest in NSW in 2001.The Dolphin torch has been revitalised a number of times in its 40 year life. The most recent versions of the torch (Mark 4 and 5) were created by Design Resource for the US-based Energizer company. Design Resource has been creating products for Energizer and its former subsidiary Eveready since 1989.

The development process for the Dolphin torch was typical of contemporary products designed in Australia. Initial conceptual hand sketches by the design team were used to brainstorm ideas. Foam models were used to refine these ideas and select a design direction. Prototypes made using 3D computer models and rapid prototyping tools enabled the design to be further developed and tested. Once complete, the 3D data was sent to the toolmaker and manufacturer for testing and production. This data was accompanied by a specification document outlining all the parts to be made.

The Dolphin torch Mark 5 received an Australian Design Mark and Powerhouse Museum Selection Award in 2003. The innovative features of the new design include: integrally moulded rubber shock impact zones on lens ring; new reflector design incorporating dual facet technology; adjustable stand; improved user ergonomics; and optimal 4 D cell battery cartridge, and a hydrogen dissipator to prevent the build up of gases from leaking batteries from within the sealed boundaries of the waterproof body.

These concept sketches for the Dolphin torch Mark 5 were created by Angelo Kotsis, designer at Design Resource, Crows Nest, NSW, Australia, in 2001.

Design Resource was asked by their client Eveready to redesign the old Dolphin lantern. Eveready wanted the new torch to look modern and stylish with extra features to make it appeal to customers.

The designers researched the other torches on the market to find out what the competition was like. The group of designers brainstormed creative ideas for how the new torch could look and work. The client, Eveready, helped to pick the design they thought would appeal most to customers. It was the design by Angelo Kotsis that was chosen to develop into a real torch.

Then Angelo and the team had to work out how to construct the new torch. They worked with engineers and manufacturers to test and develop the design using models and prototypes until the new torch was complete. The Dolphin was in production in 2003 and for sale soon afterwards.

There were some design criteria specified by the client that Angelo and the designers had to consider. They had to make sure the new torch:
- could be used with existing types of batteries
- could use a particular type of lamp
- included a stand (this was a new aspect they had to design into the torch).

These sketches were lent to the Museum for display and reproduction in the exhibition 'Sydney designers unplugged: people, process, product' from 6 August to 9 October 2005 and subsequently donated to the Museum.

The Dolphin torch has been revitalised a number of times in its 40 year life. The most recent versions of the torch (Mark 4 and 5) were created by Design Resource for the US-based Energizer company. Design Resource has been creating products for Energizer and its former subsidiary Eveready since 1989.

In 1966 Eveready in the USA designed and manufactured the first Dolphin torch - a large torch for world sales. It did well, but in 1973 Eveready's Australian arm redesigned the torch for Australian conditions, using an Australian design company. The new torch had to be shock resistant and waterproof. The designer Paul Cockburn of Design Field in Sydney insisted that it should be fairly ugly because he believed that many people would see this as a sign of ruggedness and reliability. He also wanted the torch to be multi functional, so he gave it an angled head that threw light down onto the path ahead or up when placed on the ground, useful when you're changing tyres in the dark. From 1978 until 1989 Cockburn's Dolphin Mark II was the best selling torch in the world. Another redesign in 1989, again by Cockburn, created the even uglier, high-tech styled Dolphin Mark III.

The Dolphin torch Mark 5 received an Australian Design Mark and Powerhouse Museum Selection Award in 2003. Over 100 products were entered in the 2003 Australian Design Awards and 68 of these were selected as finalists. Five judging panels (in the categories of furniture design, engineering design, industrial design, textile design, and software and electronics design) recommended 56 of the finalists for a Design Mark and 25 of these for a Design Award. The products receiving Design Awards were announced at a presentation night on 9 May 2003 at the Melbourne Town Hall. At this function, the Museum's Director (Dr. Kevin Fewster), announced the recipients of the Powerhouse Museum Selection awards for 2003.
