How a rocket scientist from Oxford University has reinvented the saucepan !

How a rocket scientist from Oxford University has reinvented the saucepan !

Telegraph - By Sarah Knapton, Science Correspondent

 Dr Thomas Povey from Oxford University spent three years developing the new pan that channels heat from the bottom up the sides so that food is warmed much more quickly

Cooking might not be rocket science, but it has taken a rocket scientist from Oxford University to reinvent the humble saucepan.


 

Dr Thomas Povey, who usually works designing cooling systems for jet engines, has come up with a new pan which heats up more quickly, cooks food faster and uses 40 per cent less energy.

Dr Povey, who is a keen mountaineer, decided to tackle the problem after struggling to heat up water at altitude.

He realised that a large amount of energy is lost simply heating the pan, rather than boiling the water.

“The original idea was for the outdoor market - we wanted to improve efficiency for cooking outside,” said Dr Povey.



"But we realised it was problem that applies to the domestic market. So we worked from there."
The cast aluminium pans channels built into the side to allow heat from the bottom to travels up the sides so that food is warmed quickly from all the way around.
An equivalent pan of conventional design was shown to need 40 per cent more energy to heat up than the new ‘Flare Pan.’
"There's nothing wrong with (a usual saucepan), but it loses a lot of heat, which means it has less energy efficiency, which means it wastes more heat, energy, and gas,” said Dr Povey.
"For instance if you were boiling pasta you may think it takes a long while to get the water boiling, but you would see a significant time improvement with this new pan and it would cook quicker.
"We've done a number of test kitchens and the chefs seem to like it, mainly down to the even heat distribution. But that is down to the good casting of the pan, as well as the product."
The pans, which were launched yesterday, are sold through Lakeland.
Dr Povey specializes in the designing of cooling systems for parts of jet and rocket engines that reach very high temperatures.
He added: "The problem with the current shape of the pan means a lot of the heat is dissipated into the air.
"So, it is an aero-dynamic and heat transfer problem and we applied the science used in rocket and jet engines to create a shape of a pan that is more energy efficient.
"So, it is a very similar problem but it certainly is a different product than what we're used to working on." .
Even before their official launch, Flare pans have already become an award winning product.
The Worshipful Company of Engineers, a Livery Company of the City of London operating under Royal Charter, has awarded Dr Povey their '2014 Hawley Award' for "the most outstanding Engineering Innovation that delivers demonstrable benefit to the environment."
Matthew Canwell, Lakeland's Buying Director added: "People are becoming more energy conscience. This pan is energy efficient, it cooks quicker, and it saves gas and energy. So it ticks all the boxes really."
“We're always looking for new innovations that will save our customers both time and money.”

How to Design a Frame Quickly Using Solidworks Simulation !


How to Design a Frame Quickly Using Solidworks Simulation ! 


 

CHALLENGE:

Streamline the development of bicycle frames, while simultaneously reducing weight and improving performance.

SOLUTION:

Implement SolidWorks Motion and SolidWorks Simulation capabilities in tandem with SolidWorks 3D CAD software to create a virtual test bench for bicycle frames.

RESULTS:

• Shortened time-to-market from 18 to 10 months (44 percent)
• Decreased number of prototypes from three to one
• Reduced frame weight by an average of 25 percent
• Increased frame stiffness by an average of 30 percent





When the company moved into a large, modern production facility in 2001, its engineers explored migrating from 2D to 3D CAD tools as part of an effort to utilize the latest design technologies. Cycles Devinci had previously used Working Model® 2D, AutoCAD®, and Mechanical Desktop® design software, according to Bruno Gauthier, R&D Department director.

 

Making the steep, long climb from a fl edgling company of two people in 1987 to becoming a major player in the bicycle industry, Cycles Devinci, Inc., has set its course on the use of cutting-edge product development methods. When company President Félix Gauthier purchased Cycles Devinci in 1990, he saw the company’s
potential and established an industrial manufacturing process that would lead to large-scale bicycle manufacturing. Today, Cycles Devinci has grown to become the top producer of bikes in Canada and a worldwide leader in the manufacture of highend mountain and road bikes.




“We wanted to take advantage of the power of 3D design to streamline and improve our product development process,” Gauthier recalls. “In addition to accelerating time to- market, we believed 3D would help us to leverage simulation and analysis tools not only to reduce the weight and improve the performance of our bicycle frames, but also to cut the number of prototypes needed.”

   
 

“We are a fast-moving company of young people who are used to thinking in 3D,”
adds Philip Maltais, testing engineer. “So we needed to work in 3D to design more complex bikes, show concepts more effectively, and develop a virtual testing capability – utilizing fi nite element analysis (FEA) tools – to gain speed and boost performance.”

Cycles Devinci evaluated Solid Edge®, Autodesk Inventor®, and SolidWorks® 3D CAD software before choosing SolidWorks and implementing integrated SolidWorks Motion and SolidWorks Simulation software. The company selected SolidWorks because
of its ease of use, 3D visualization capabilities, and simulation/analysis tools, which support the bike manufacturer’s goals of reducing development costs and accelerating
time-to-market. Cycles Devinci engineers also viewed the expertise of its reseller, SolidXperts, as superior.

Improving performance with virtual test bench Using SolidWorks Motion and SolidWorks Simulation software, Cycles Devinci
engineers created a virtual test bench, which enables them to simulate frame performance in software. With these studies, engineers modify and refine bike frame designs to achieve the optimal strength-to-weight ratio. This approach enables them to
reduce the frame weight by an average of 25 percent and increase frame stiffness by an average of 30 percent, thereby producing lighter, stronger bikes.
“The combination of SolidWorks Motion and SolidWorks Simulation can do the same job as any of the big FEA packages at a fraction of the cost,” Maltais stresses. “We have confirmed the accuracy of these analyses through actual testing. The results of
the motion studies provide accurate loading conditions for conducting subsequent stress analyses. With load accuracy, we are able to increase and control fatigue life, while maintaining an acceptable factor of safety, allowing us to reduce frame weight
and extend the life of the bike at the same time.”

Reducing time and prototypes Since implementing its SolidWorks-enabled virtual test bench, Cycles Devinci has realized significant productivity gains, while simultaneously increasing the number of
innovative concepts it develops. With this capability, the company has reduced time-tomarket for its bikes from 18 to 10 months – a reduction of 44 percent – and has cut the number of prototypes required from three to one, resulting in substantial cost savings.
“We have deployed the SolidWorks virtual bench test on all four of our product lines, which include road, mountain, and hybrid bikes, as well as the new BIXI Public Bike System in Montréal,” Gauthier notes. “Our product development process has become faster and more cost-effective, and the quality of our bikes continues to improve.”
Boosting innovation with BIXI The design intelligence afforded by SolidWorks Simulation technologies has enabled Cycles Devinci to increase the number of new concepts it develops. One of its more
innovative designs is the bike that is used in the BIXI Public Bike System in Montréal, a system of 300 bike stations with 3,000 bikes available for rental and use across the city. Riders can take a bike from one automated station and return the bike to any station. The design won the GOLD Best Product of 2009 Award in the Energy & Sustainability category of the prestigious Edison Best New Products Awards.


“We designed the BIXI bike, ran the virtual tests, and made adjustments prior to actually producing the prototype,” Gauthier points out. “SolidWorks allows us to quickly take a product from design to production, even with an innovative project like BIXI.”
