- Cerebra, a national charity for brain injured children required an improved design and manufacture process for sports helmets. This required: a novel method of anthropometric data capture that addresses the challenges of measuring a child’s irregular head form when head-movement and other conditions such as autism and lack of cognitive understanding could cause distress if conventional contact measurement techniques are used; design and performance constraints required by the British Standards Institution; and cost-effective solutions that increase inclusion for a broad demographic. The research solution focused on the design of a remote process for data capture that does not require specialist equipment, so that support can be given to a wider geographic audience. The research considered the comparative accuracy of different data capture options based on a multi-methodological approach including literature review and experimental work. The initial phase investigated the use of a non-contact white-light scanner for a child with severe autism and craniosynostosis. The second design phase investigated and developed an original process for remote data capture of a child’s head using non-specialist equipment (smart phones) by non-expert users (e.g. parents). User experience evaluation and validation, covering comprehension of process and ease of use by non-expert users using non-specialist equipment was undertaken. Acquired images are post-processed using photogrammetry software for subsequent generation of CAD data for the manufacturing. Non-contact measurements demonstrated that 3D geometry could be accurately acquired in difficult patient circumstances, which successfully overcame the challenges of continuous head movement, cognitive and emotional behaviour. Work led to the development of new process for 3D data capture by non-experts using smartphones. Composite design and digitally-driven additive and subtractive manufacturing processes were validated by attainment of the British Standards Institution certification VG1 01:040 2014-12. This design process was delivered to Cerebra and physical helmets develop for clients in July 2019
