Executive Summary:

Haughton Design provided multiple conceptual proposals for a Patient Handling Device. The client presented HD with a list of IP documents, and set out the core objectives of the design task to: Design an inherently safe device; Design the device as low-cost as possible; Not to infringe on any existing IP; To develop a final concept design proposal in 2 weeks. The work was completed swiftly with a simple and highly effective solution generated meeting all aspects of the brief.

HD’s Design Sprint service allowed for incredibly fast development of multiple conceptual designs to be performed in parallel. Continual reflection of the core objectives and design brief constraints was challenging but resulted in a final concept which was verified via FEA to ensure it met all typical use case scenarios, all whilst being just a single piece part component. The conceptual proposal was further developed for production and initial testing exceeds competitor devices in all attributes of performance.

I was really impressed with todays presentation showing the progress and initial ideas so far, so thank you!

The client wished to rapidly explore the opportunity for developing a novel Patient Handling Device.

The client’s team were only allocated a small pot of investigative funding, with additional funding to be granted upon further fruitful development of an acceptable conceptual solution. The client knew that it may be possible to achieve their objectives, but they weren’t sure how it could be achieved, nor what form it would take. Therefore, they requested assistance from HD.

By tailoring a Design Sprint service to meet the clients commercial and timeline requirements, HD were able to develop a bespoke stage gated program to validate the opportunity.

HD reviewed findings from an independent IP investigation with the client and also with their legal department to review certain claims. This ensured that the patent landscape was fully reviewed by all parties and proved there were potentially unexploited areas and features which could be addressed.

Once the patent landscape was understood, HD developed numerous broad-brush sketches to demonstrate the potential features and mechanisms to be explored, with spin off research tasks for further investigation into how other devices from other sectors cater for similar use case scenarios, i.e. ‘Other Vision’.

The client was brought into several design sprint sessions to ensure that their core objectives were continuously met for each and every design, and the sessions were able to build upon the initial ideas which HD had generated. This collaborative approach to the design process allowed us to create a more effective and stronger commercial proposition overall.

Once a design was selected, HD 3D modelled the proposal in CAD, and iterated the design using a combination of FEA analysis and rapid prototyping to test both ergonomics and mechanical strength of the product.

A working 3D prototype was produced to showcase the solution we generated to the client’s Board of Directors for final approval, this secured further funding to allow the project to progress into the next stage of detailed development.

The design has been since developed for production and initial verification tests exceed competitor devices in all attributes of performance.
