My design – Improvement to the traditional cane tea collector

Filed under: design,designs,engineering,innovations,tea,tea collector — madhawa.h @ 8:54 am
This is a design I and 3 of my friends suggest for improvement of the traditional cane tea collector.

Question
The traditional cane tea collector basket used in the tea industry is becoming increasingly unpopular among the new generation of state workers. There is a need for an improved basket that will overcome the disadvantages of the traditional basket. What are the factors you have to consider in developing a new design solution for collecting fresh tea leaves plucked by the state workers?

Main factors which should be considered

 Preserve the freshness of the leaves
 Comfortability of the collector
 Higher capacity, to collect more tea leaves at a time
 Easy and compact in transportation and storage of the baskets

Disadvantages/weaknesses of the traditional cane tea collector

 The basket is heavy, because it is made out of cane
 Because of the round shape, the basket can rotate around it when it is hanged on the back/around the head
 Low life time
 Incomfortability to the collector (can cause pains in back and/or neck)
 Difficulty in storing the baskets because the baskets are handmade and can be in various sizes

Solutions we decided

 New basket will be made by nylon strings (with spaces on the wall)
 Air can circulate through the spaces on the wall, so that the leaves will not braise
 That will reduce the weight of the basket
 Nylon has more life time than cane
 The new design can be stored in a small space, because it can be folded

 The shape of the basket is changed to a shape which will not waggle around the user
 The round shape is changed in to a shape where wore surface will touch the user’s back

 The shape of the basket changed to comfort the user
 That will reduce the pains the user will face

NEVER CRY FOR ANY RELATION IN LIFE
BECAUSE FOR THE ONE WHOM YOU CRY
DOES NOT DESERVE YOUR TEARS
AND THE ONE WHO DESERVES
WILL NEVER LET YOU CRY……………..

TREAT EVERYONE WITH POLITENESS
EVEN THOSE WHO ARE RUDE TO YOU,
NOT BECAUSE THEY ARE NOT NICE
BUT BECAUSE YOU ARE NICE…………………..

NEVER SEARCH YOUR HAPPINESS
IN OTHERS
WHICH WILL MAKE YOU
FEEL ALONE,
RATHER SEARCH IT IN YOURSELF
YOU WILL FEEL HAPPY
EVEN IF YOU ARE LEFT ALONE………………….

ALWAYS HAVE
A POSITIVE ATTITUDE IN LIFE.
THERE IS SOMETHING POSITIVE
IN EVERY PERSON.
EVEN A STOPPED WATCH IS RIGHT
TWICE A DAY………………………………

HAPPINESS ALWAYS LOOKS SMALL
WHEN WE HOLD IT IN OUR HANDS.
BUT WHEN WE LEARN TO
SHARE IT,
WE REALIZE HOW BIG AND PRECIOUS IT IS!……………..

Does Love Need a Reason

Filed under: Uncategorized — madhawa.h @ 7:51 am

Some people never understand
Once a lady when having a conversation with her lover, asked:

Lady : Why do you like me..? Why do you love me?
Man : I can t tell the reason.. but I really like you..
Lady :
You can t even tell me the reason… how can you say you like me? How can you say you love me?
Man :
I really don t know the reason, but I can prove that I love U.
Lady :
Proof? No! I want you to tell me the reason. My friend s boyfriend can tell her why he loves her but not you!
Man :
Ok..ok!!! Erm… because you are beautiful,

because your voice is sweet,
because you are caring,

because you are loving,

because you are thoughtful,

because of your smile,

because of your every movements.

The lady felt very satisfied with the man s answer.
Unfortunately, a few days later, the Lady met with an accident and went in comma.
The Guy then placed a letter by her side,

Darling,Because of your sweet voice that I love you…Now can you talk? No! Therefore I cannot love you.
Because of your care and concern that I like you..Now that you cannot show them, therefore I cannot love you.

Because of your smile,because of your every movements that I love you..

Now can you smile? Now can you move?No, therefore I cannot love you…

If love needs a reason, like now,There is no reason for me to love you anymore.

Does love need a reason?

NO!Therefore,
I still LOVE YOU…

True love never dies for it is lust that fades away. Love bonds for a lifetime but lust just pushes away"

 Immature love says: 'I love you because I need you.' Mature love says 'I need you because I love you.'
