Product Information

Even if only anything puts power, a core is not broken
Mechanical pencil "Dell guard"

A mechanical pencil is the writing implement which 90% of junior and senior high school students uses for study every day.
However, when it concentrated on it, and it laid emphasis on a pen, a core was broken, and it was the greatest non-perfect score a core was clogged up inside, and not to appear.
"The Dell guard" breaks off the dissatisfaction with two features.

Features 1 protects a core from how the strong pressure of the pen of every writing angle not to compromise. [patent pending]

When strong pressure of the pen increases perpendicularly for the space, the spring which the axis had built-in misses a core in the upper direction and prevents buckling up.
When strong pressure of the pen increases diagonally, metal parts of the tip automatically come out and wrap up a core and guard it.
その二つの機構が、加わる力の角度や強さに合わせて自動で配分を調整して作動します。
(when I knock more than four times from the state that ※ core is not over and write it, I may compromise.)

Features 2 prevents that a core is clogged up inside and does not appear. [patent pending]

I am even out of a short core by having attached the parts which guide a sharp core to the axis inside and may not be clogged up.

An effect: I can concentrate on what a user writes in peace in the important scenes such as the everyday study or test by being usable without minding core buckling up and core jamming.
"The Dell guard" provides the best performance to junior and senior high school students.

"The Dell guard" is the first product which solved the biggest dissatisfaction of the junior and senior high school students for the mechanical pencil by normal how to use.

Development background
In the mechanical pencil market, the sale amounts of money of the decreasing thing increase by the sale number year by year.
It is a high-performance type about 500 yen to play key role, and a new product is put by the companies.

Mechanical pencil market change (I make it than production of Ministry of Economy, Trade and Industry dynamic statistics)

Sale amount of money (Nikkei POS data) according to the mechanical pencil price

Development process
A share was lower than a ball-point pen and markers in a mechanical pencil market, and the zebra did not have the high-performance mechanical pencil product by the company technology.
I began development of the epoch-making mechanism to solve the dissatisfaction of the junior and senior high school students who were a hard user in 2009.

I carry out 1, use of mechanical pencil fact-finding of the student.
I start that I solve the fault of the fatal mechanical pencil for junior and senior high school students, "writing is stopped when a sharp core compromises and is clogged up, and concentration breaks off" who are a result, a biggest dissatisfaction point.

I carry out the action observation of the student in a private supplementary school and a school to grasp the situation that 2, a sharp core are broken.
It is attention in an angle and pressure of the pen having a pen varying, and changing by the use situation including the mark sheet of a notebook and the examination by a person.


I take out 60 plan or more in a development team and I produce most experimentally and test an idea of the mechanism not to let you clog up not to let you break 3, a sharp core.
The product which was not broken had even conventional other companies product, but was particular about development of the mechanism not to compromise because I did not do normal how to use without a user minding how to use at all this time.
However, mechanism to solve core buckling up by the pressure of the pen to the slant direction is in particular difficult and runs into difficulties.


From 4, the mechanism that I produced experimentally, I adopt two of the mechanism to miss a core for mechanism that metal parts jump out at the same time to take pressure of the pen diagonally and guard and perpendicular power in the upper direction.
Furthermore, I put it together in an angle and strength of the power to increase it to operate it by automatic distribution in total.
I change each spring and produce combinations more than approximately 100 kinds experimentally.
After the use test by 50 general users, mechanism not to be broken even if I did any how to use was completed.


Because 5, metal parts automatically exit and guard a core, I name it "Dell guard system".
Furthermore, I planned minimization of the mechanism so that it was not disturbed at the time of writing and put it in the axis of the design of the on the small side that was the preference of the student.
