Principle:
9 Windows System is a system is a is a simple means of helping users to think in terms of TIME and SPACE. The basic principle of this system operator is that users have to divides the situation into nine segments. The central box of the nine - "system, present " is the one we naturally migrate to whenever we are given a problem situation. This system help us to define the problems along with time, and from macro-environment to micro-environment.
Our application:
We define the existing and predicted problems of folding chairs by 9 Windows System Operator. The problems include:
․" Sub-system - Before" → " Super system - Before" These are the problems of the previous stages of folding chair life cycle. We found out that the production cost increase if the folding chairs assembly with many small components, furthermore, because of the large amount of components, the assembly cost and time will increase at the same time.
During the transportation, the folding chairs will be damaged easily since they are quite bulky. Also, they are not made by recycling materials so they are not very environmental-friendly.
When the folding chairs are sold at the shop, they are bulky and difficult to be stored at the shop, moreover, maybe they are dangerous for children and broken easily by customers' trials.
․" Sub-system - Present" → " Super system - Present" From the central box of the nine - "system, present ", we can define the main existing problems of folding chairs nowadays. We found that they are bulky, heavy, unmovable, and they only have single function. Besides, since most of the folding chairs are hard, designed with a fixed height, and no curve is contained so they are not comfortable for users.
Because of above problems, the folding chairs come with further problems to the users in home and office. The problems are listed in " Super system - Present".
․" Sub-system - Future" → " Super system - Future" The folding chairs are difficult to be degraded when they are abandoned to landfill since most of them are difficult to disassembly and non-recyclable.
From " Super system - Future", we found that the chairs have mould easily since they are made by nylon, and the plastic part of the chairs maybe will be deformed and cracked. As the legs of most of the folding chairs are made by metal, they rust easily.

Chairs sticking out in the dining area – In the dining area, when people had finished their meal, there would be chairs left sticking out. This could cause a problem if there was an emergency because the staff may not be able to get there as fast as possible, or an elderly person may hit their hip on the chair and cause injury. I recommended that staff should put the chairs in if the residents forget, and to remind the residents to put them back after use. However a lot of the residents are very elderly and may forget to do this, and members of staff could be too busy to be pushing chairs in after everybody.…

This is probably because of its portability being easy. It was expensive to make the stool, even when it was in its simplest form. Stools were used by both slaves and emperors. Those who were poor got plain stools, while those who were wealthy had access to precious woods, had ornaments inlayed, metal fittings, ivory, silver and gold leaf. The bronze stools from Herculaneum were square in shape. It had straight legs with decorative stretchers and a dipped seat. An important indicator of power in the Roman period was the folding stool.

Dozens and dozens of recliners. Each of them has a unique color and style to them. I see a red leather recliner that my tiny granny would absolutely love and a huge brown recliner that both Shaquille O’Neal and my granny could share. It amazes me how much of a variety there is. Charlie can see just how amazed I am by all of the recliners and tells me to try them out. Immediately, I briskly walk over to the oversized, brown recliner just to see truly how big of a chair it is. Charlie sits across from me and tells me a little about the store’s most popular item, the La-Z-Boy recliner. La-Z-Boy is a very popular and affordable furniture brand that makes all types of upholstery. In the furniture business, upholstery refers to sofas, recliners, sectionals, chairs, loveseats and more.

Chairs have been around for as long as mankind has. As soon as the need to rest developed, chairs developed. When I think of a chair, I immediately think “four legs, seat, back, etc.”. But is this really what a chair is? Could you not also place a book on this “chair” and it would now be transformed into a table? Is it possible that I could sit on a table, or a stump, or a bed and it would now be a chair? How do we as humans instinctively know what chairs are? When are we taught to know the difference between chairs and other furniture? Is it just implied, or is there something deeper in our psyche that tell us these things. These questions have been asked for as long as people have given thought to how the the world works around them. As we have read in works by Lucretius, Plato, and now Descartes, we are looking for the answers of the age old question “What is a Chair?” by also analyzing the questions of mankind that come along with this deeper thinking.…

It occurs mostly in a straight column when the stable equilibrium gets distorted at the critical load. The buckling is shown to occur mainly at the axis and demonstrates significantly small radius of gyration. There are different types of flexural buckling that can take place in objects and different equations can be employed for determining the load and the extent of buckling caused due to the same.…
