After Buddha Sakyamuni and Jesus Christ,Xuefeng (Deiform Buddha) ,the messenger of the Greatest Creator,followed Revelation founding Lifechanyuan to give the last course for human beings to learn and follow since year 2003 and before 2013:
The pyramid is the “womb” for the birth of mankind, filled with unlimited mysteries, which once discovered by man, will have a direct bearing on the question of whether man should continue to exist on earth. Just like the modern “cloning technology”, the mass reproduction of man will pose a direct threat to the balance of various space life-forms and destroy the “transmigration order” of life. Man should be kept from taking such risks.
Then what punishment will be met out for those daring to break into the pyramid?By the pharaoh’s curse, all those interlopers would be killed so that no secrets could be leaked.

Development of a Conceptual Space Smart Kitchen MixerMarlene Holm
The authors and designers Marlene Holm and Olof Nordström, have developed a product concept based on the former kitchen mixer Electrolux N15, that fills the gap in the product segment that is referred to as ’Urban Compact Living’, in which there is currently no equivalent product offered.
The focus has been on understanding the market segment and defining the target customer in order to conduct multiple user tests and observations to design a product with high usability and user satisfaction.
Two stand mixers of the wall mounted model Electrolux N15, with all the attachments and manuals, was purchased and forms the base for making the practical tests and studies.
Much of the work consists of usability analyzes in order to understand what users want, both what they consciously seek but also implicit needs; what they do not yet know that they want. User studies are conducted where users are observed and the product’s usability is analyzed with the help of a CW, -Cognitive Walkthrough and a PHEA, -Predicted Human Error Analysis test.
Electrolux's design dna is analyzed to create a product that exudes their visual brand identity and meet the customer expectations. The idea generation is an iterative process where creative tools such as brainstorming, exploratory sketching and clay modelling are used to create the concept, its features and final design. To further develop and visualize, the concept is 3D-modeled in CAD software and finally rendered into photo realistic images. A full scale prototype is made using a 3D printer to evaluate the shape and the size.
The result is an innovative, user friendly and time saving stand mixer that inspires people with an urban lifestyle and a compact living to a true and wholesome cooking experience.

This document outlines the design of an outdoor rostrum. It begins with an introduction and background on rostrums and their uses. The author then identifies the need for an improved outdoor rostrum that considers factors like weather, electricity access, portability, durability, and the number of audiences.
The proposed design concept focuses on portability through a folding mechanism to reduce space needs and allow for more rostrums to be transported. Key features include a lightweight and waterproof construction with lockable wheels and a battery-powered microphone.
The document presents the methodology used to develop the design, which included identifying customer needs, specifying product requirements, generating and selecting concepts, testing models, and selecting materials. Analysis

One Touch ™ Can Opener
With sales of over 125 million units each year, the can opener is perhaps the quintessential everyday
tool. Since its invention in 1858 many different types of can opener varying in design and operating
innovation.
With no real change in the concept for many years and yet nearly half a representative sample of test
users reporting that the strength needed to grip a manual can opener’s levers while simultaneously
turning the handle was beyond their comfort level, DAKA set out to design a cordless, hands-free
can opener that could be easily used by anyone to open a can with the simple touch of a button.
The result was a multi award-winning, international best selling product.
The Problem
50Kg (100 lbs) and then requires an additional burst of power to actually pierce the can lid. When a
person uses a manual can opener, the application of appropriate force is instinctively adjusted until
To reproduce this in an automatic mechanism is not easy as evidenced by the many electric can
openers that still require human force to pierce the lid and start the cutting action. What was needed
was a mechanism that could not only walk the cutting blade around the can automatically as many

number of parts. To achieve the necessary reduction in parts, value engineering and intense
optimization was called for, central to which was the injection moulding process which would enable
multiple features and functions to be integrated into each part.
Using injection moulding conveniently afforded the creative team together with lead design consultant
Mark Sanders of MAS Design Products Ltd., the almost total creative freedom that a project such as
this called for. Most of the design goals were indeed met when it was realised that the drive gearing
for the powerful cutter could be combined with a ‘geneva mechanism’ for the timing function using
the same parts
and precision required for each part was achieved. For the internal mechanism, Acetal (plastic
Choosing Acetal also eliminated the necessity for separate bearings, allowing the part count to be
reduced even further.
The result was a unique (and patented) mechanism, made of just 3 parts. Several functions being
integrated into each part which can generate the necessary 50 Kg force, provide the timing function

The Design
In the early stages of design, several concepts were developed and full size mock-ups were tested
focus on ease of manufacture, rather than ease of use. They highlighted elements of early mockups
that made the shape more unattractive or introduced ‘dirt traps. They also highlighted just how
can opener functioned better were chosen over those prototype openers that actually did function
better - a clear signal that the key to creating the ultimate can opener lay in the combination of
superior functionality and attractive design.
“Simplicity is the ultimate sophistication.” Leonardo Da Vinci
alongside the product’s overall shape. In fact, bearing in mind the importance that design would
clearly play in the product’s success, even the appearance of the internal details was carefully
attractive.
With the number of parts down to a bare minimum and with the comments of the test panel in
mind, unsightly features were then eliminated from the design; the can opener’s cutter and drive
wheels were made to retract when not in use which also meant the potential for any user injury
streamlined by splitting the unit into two halves which could be easily slid apart.
the sharp edges and even sharper blades of traditional can openers proved altogether more inviting
to the touch.

Conclusion
– as evidenced by the One Touch™ Can Opener’s success.
Can Opener has proven highly popular with all audiences. Household buyers like its sleek design
and the convenience of a small, battery-operated but powerful opener. Parents praise its safety
without the manual strength to initiate an opener’s cutting action.
The runaway success of the One Touch™ can opener - over 7 million units have been sold to date
- pointed to the overwhelming market potential for simple, smart, handheld kitchen appliances that
address practical needs with style. From this core concept and following the same philosophy, a
whole family of products has been developed under a new One Touch™ brand including a jar opener
and a wine bottle opener amongst others.
