Human powered racing submarinesAim: complete a technical design and construct a business case for the future generation racing submarine for the Bath University Racing Submarine Team (BURST) 2013.

Keywords: teamwork, optimise, high performance

2012-ongoing, team of ten, project manager. Three months.

A complicated and integrated technical design with multiple subsystems required careful management and contained many trade-offs. Sketching was used extensively to explore the solution space and com-municate ideas within the team.

BURST have been competing in the Inter-national Submarine Races (USA) since 2007 and have a strong track record. The chal-lenge is a 6m deep, 100m long drag-race in a flooded-hull submarine with pit crews and pilots breathing through scuba.

The theoretical performance of concepts were evaluated to assist decision making throughout the project. Calcula-tions also provided verification that the team would be able to achieve their performance tar-gets.

Mathematical models were created to simulate the sub-marine’s performance. Visual representation and analysis guided the following design tasks and decisions.

Minimising the hull volume was a critical aspect of the design. A life size mock-up was created early in the project to verify that major components would fit within the hull.

Detail design work took place using Siemens Solid edge. The embodiment of the design aided visu-alisation and communication: useful for generating solutions to physical and technical conflicts.

The final rendered CAD assembly embodies three months of detailed itera-tive design and collabora-tion.

Multi-jet modelling was used to create a 1:10 scale model of the final hull for a design exhibition. The first attempt collapsed before curing due to inadequate wall thicknesses.

A global datum system was employed to speed up the general assem-bly and overcome working with complex geometry. Ten subsystems and over 400 components took less than one day to assemble without conflicts and to the required accuracy.

Biomimetic jumping robotAim: design and build a biomimetic jumping robot from cardboard and other common stationery items.

Keywords: model making, analysis, testing, interdisciplinary

2012, solo. Two weeks.

Analysis of the problem identified the centre of mass as critical. Controlling the position of this relative to the jumping forces was a key design requirement, and was made possible with a symmetric design.

The revised design is very different, yet still encom-passes the key features: symmetry, and the flea’s jumping mechanism.

The robot was inspired by the common flea, who can jump 200 times its own body length. The flea’s jumping mechanism was obtained and adapted from literature for a first prototype.

This was an assessed pro-ject as part of an under-graduate course on biomi-metics.

The first prototype very closely resembled a flea. Unfortunately, it did not jump as there were too many uncontrolled design aspects; their contribution to jumping performance were not fully understood.

Chai me to the moon LLCAim: optimise the tea brewing process and identify areas for im-provement, advise on equipment design for a student start-up in Stanford, CA.

Keywords: deconstruction, optimisation

2012-ongoing, team of four.

Chai me to the moon LLC started with the desire to make great tea, and share it with other students. What emerged was a community of tea lovers.

After a year of success, it was necessary to bring operations in line with California state leg-islation, requiring an upgrade to equipment. Reducing op-erations to one person also required a streamlining of activities.

I was asked to consult on the optimisation of the brewing process and modifications of an old hot-dog cart.

The brewing process was deconstructed ‘as-is’ in order to better understand the tasks for the operator. Simple rules such as avail-able task bandwidth and sequencing were applied.

The process was then rede-signed according to these rules. Analysis of the pro-posed process identified critical processes (e.g. boiling time) and will help guide the future hardware design.

Information has been omit-ted from the diagrams to preserve Chai me to the moon LLC’s IP.

Carton folding mechanismAim: design a mechanism to perform one fold in a carton erector machine and calculate the kinetic energy in one cycle.

Keywords: calculation, analysis

2011, solo. One month.

The task was to design and ana-lyse a mechanism for one stage of erecting a carton: stages 5-6 highlighted left, an angled tri-angular fold.

This was an assessed project for a course on computer aids in de-sign.

The design needed to operate around the carton, resulting in a split mechanism and pusher bar.

The final result of the pro-ject were graphical repre-sentations for the kinetic energy of the mechanism through one folding cycle.

These models were then programmed into the original constraint mod-eller. Learning the lan-guage (a C variant) on a short timescale proved challenging.

The primary aim was to use computer aids to cal-culate the kinetic energy of the system. Understanding concepts of world-views was a key challenge to de-veloping the theoretical mathematical solution models.

The linkage was then embodied in a virtual 3D prototype.

The desired motion was com-plex: a push-in and press-along the fold. A constraint modeller was used to generate a 4-bar linkage that performed the de-sired motion.

7

Machining strategies for super-alloysAim: improve an existing manufacturing process by designing, simulating and implementing state-of-the-art machining strategies on legacy machinery for Oldland Aerospace Ltd., Bristol.

Keywords: constraints, collaboration, testing

2011, Solo. One month.

Shop-floor testing runs required working closely with machine operators. Scrappage was a sharp lesson on attention to de-tail. The new process pro-vided a 20% reduction on spindle times.

As the machines these were implemented on had very limited memory; all the programs had to fit on one floppy disk, a real chal-lenge for multiple programs containing over 2000 lines of code each.

Collaborating with a sup-plier provided state-of-the-art tooling and technical advice to calculate optimal machining parameters and cutting head routes.

This project aimed to design and simulate a proposed new pro-cess before testing and imple-mentation. A millimeter-accu-rate model of the CNC machine was created in Catia and used in simulations.

The billets and tools were then modelled and the existing pro-cess tested in Vericut to estab-lish a baseline performance.

Detailed simulations deter-mined information on final accu-racy, finish and duration of the process. It provided a compari-son to the baseline.

8

Space efficient bed frameAim: design and build a space efficient double bed frame for a small room with limited material and tools.

Keywords: constraints, low-cost, fast time-to-market

2011, team of two. One week.

Aesthetic light jarAim: manufacture an autonomous aes-thetic lighting device.

Concept: repurposing, gadget

2010, Solo. One week.

The project was on a short time scale. Budget and time requirements dictat-ed that materials and tools had to be cheap, and readily available, restrict-ing choices.

The final design was based on sim-plicity. Materials were off-the-shelf and readily available, tools were bor-rowed from friends.

The completed bed.Moving into a new house and faced with an empty bedroom, buying a new space efficient bed frame proved too expensive. It was decided to design and build one in order to save mon-ey.

The solar lights were disassembled and repackaged into mason jars. Re-fitting the delicately manufactured electronics was challenging.

Cardboard provided a quick method of prototyping the scaffold for internal components.

The finished light jar will turn itself on and off, recharging its batteries when in light.

The desired functions were similar to a solar garden light: rechargeable bat-teries and an automatic on-off switch.

9

Elaborate gingerbread structuresAim: build elaborate and challenging gingerbread structures and create a tradition involving extended family around the world.

Concept: challenge, fun, international, innovation, model making

2009-ongoing, teams of two to six. Typically one week.

Cardboard models are used to gauge the size of the final structure and calcu-late volume of gingerbread required.

The models are then deconstructed and used as cutting templates for baking the gingerbread.

The current 2012 entry, the Roman Baths, aims to continue the trend of complicated, challenging design.

The original gingerbread castle was born whilst looking for a festive chal-lenge. It was so much fun that we de-cided to share it with our extended family around the world.

A set of simple rules were designed to provide a framework for the activity and create an annual tradition.

Designs were inspired by recent activi-ties such as travelling. Excessive de-tail was a recurring theme: this tower (near right) leans at exactly 5.5 degrees from vertical (identical to the tower in Pisa).

We also wanted to create cool features, such as an innovative stained-glass mansion made using boiled sweets (far right).

Volunteer photographyAim: practice and develop personal photography skills, gain more exposure to art.

Keywords: collaboration, exploration

2009-ongoing, team of two and solo. Typically one week.
