Executive Summary:

Seward, who provide high quality microbiology products, reached out to HD for assistance in designing and developing an innovative laboratory paddle blender – the Stomacher 400. The new innovation greatly improves the user’s experience when processing food samples, and ensures that Seward stay ahead of their competition in paddle blending equipment.

The inquisitive and questioning nature of HD’s team allowed us to escape traditional thinking behind paddle blender design. The concepts developed by HD were truly innovative and a complete step change from existing blenders, rethinking the potential of the user experience, manufacturing methods and product intelligence.

To reduce noise, HD partnered up with Southampton University and their Institute of Sound and Vibration Research to conduct acoustic trials on noise reduction when paddle blending. This insight produced a design whereby the sounds emissions were greatly reduced, resulting in a silently operating desktop paddle blender.

Through our design and development expertise, Seward were able to verify performance and validate usability aspects of the device through prototyping. HD worked with toolmakers and moulders to ease this product into production, leading to the production of the Stomacher 400 – a market leading product. HD have continued to be a design partner of Seward, assisting them in further improvements and robustness developments of the Stomacher 400.

From day 1 Haughton Design have been an integral partner in the EVO’s development, balancing design process with the stringent requirements we placed on them. The team have done a fantastic job. – Seward

Sewards environmental policy was instrumental to developing a product based around increasing operational reliability and longevity.

We were able to balance longevity and cost by designing the blender to be as robust as possible, using high performance components, while ensuring low-cost manufacturing processes and assembly features were used.

In tandem, Seward were able to develop a more sustainable bag used for paddle blending. The Ecobags are 30% smaller than traditional sample bags, aiding laboratories to reduce their plastic usage and waste costs.

Haughton Design partnered up with GB Electronics to design the electrical hardware and software to develop a system that is focused on improving the user experience. We were able to develop a plug-and-play system with a simple control interface that simplifies the set-up and operation of the paddle blender.
