Description

The commodity reservation transaction system that a kind of Internet-based platform is realized

Technical field

The present invention relates to the commodity reservations transaction system on a kind of internet platform, belong to computing machine and internet, applications field.

Background technology

The essence of transaction is the exchange of realized value, and the basis of this exchange is its equivalence, and namely both parties will equate for the value of exchange.For this equivalence, we have only noticed the equivalence of exchange both sides exchanging contents usually, and have ignored the correlative factor in the exchange process.

The correlative factor that relates to the exchange both sides in exchange process generally has locus, time or time sequencing, exchange times, the exchange capacity of exchange.In traditional exchange process, due to the restriction of each side condition, these factors are often inessential, and the value that wherein comprises is not high, and are little on whole process of exchange impact, can be left in the basket in the process of exchange.Increasingly mature and universal along with the development of network technology, particularly ecommerce, the influence factor outside exchanging contents is day by day remarkable, for example, swapace position virtual increases rapidly numerous online shopping malls, and the trend that replaces traditional store that concrete locus is arranged is arranged.Extensive, the powerful instant communication capability of people has been brought up in the internet, can make people converge considerable purchase volume within the time of determining, purchases by group this emerging shopping mode thereby produced.

Under the internet business pattern, have important impact for process of exchange swap time, comprising certain value.For the seller, the confirmation in advance of exchange hour not only can reduce transaction risk, and can plan transaction subsequently, can exert an influence from content and the process to transaction to a great extent, thereby reduce the cost of transaction.But for the buyer, confirm in advance to have reduced choice from now on, be equivalent to the selection right of oneself is amortized, the minimizing of selection means the risk that has increased transaction.in this process, the seller is owing to reducing risks, reduce costs, be ready that more the buyer more early confirms transaction, also can think, due to shifting to an earlier date of exchange hour, can make the seller obtain certain value, this value is numerically equal to the reduction of confirming in advance the risk and cost bring of exchange hour, in other words, that is to say that the exchange hour of confirming in advance has certain value for the seller, but the buyer is because right is impaired, risk increases, more be ready to postpone confirmation, thus, the seller's the time value can not unilaterally realize, because it can damage the buyer's interests.

Under many circumstances, due to the confirmation in advance of exchange hour, the increase of seller's interest and the minimizing of buyer's interest numerically and not exclusively equate.We are called the time value to the corresponding value of this interests for both sides.When the buyer's the time value during less than the time value corresponding to the seller, just buy with lower price for the seller and have the larger time value possibility is provided.

In present marketing process, people do not utilize fully to the time value of transaction, although dim understanding and fragmentary application are arranged (as the order of air ticket, if ticket booking can obtain certain special discount in advance), but there is no fixing pattern and clear and definite rule, this has hindered the development of internet shopping technology to a certain extent.

Summary of the invention

In order to overcome the deficiencies in the prior art, the invention provides a kind of time value is more reasonable, more system, clearer and more definite being explained, and apply in actual internet business, both parties can be benefited from it, can promote the commodity reservation transaction system of internet business development.

Embodiment

With reference to the commodity reservation transaction system that Fig. 1, a kind of Internet-based platform are realized, this system's Internet-based platform realization, this system comprises:

The sell side MIM message input module: the seller inputs nominal price P, the lowest price V of commodity, minimum reservation T pre-set time on this module _min, maximum reservation T pre-set time _max, the elasticity of demand b of price, the correlation parameters such as elasticity of demand c of acknowledging time in advance;

Buyer's client information load module: the buyer inputs reservation exchange hour T on this module _t, and confirm transaction, the time of trade confirmation is designated as T _X

Time value computing module: according to reservation exchange hour T _t, minimum reservation T pre-set time _min, lowest price V, maximum reservation T pre-set time _maxWith the trade confirmation time T _x, calculate the trade confirmation time T according to predetermined rule _xTo reservation exchange hour T _tThe time value V of commodity in time period _t

Final knock-down price computing module: according to nominal price P, the time value V of commodity _tDeng, calculate commodity transaction acknowledging time T by predetermined rule _xThe End-price P of moment commodity _x

The core of system of the present invention is to introduce this concept of the time value when calculating final knock-down price, make final knock-down price and trade confirmation form a function between the time, be the variation change of final knock-down price with the trade confirmation time, fundamentally changed the marketing model of present network selling, the below elaborates on the time value and the impact in transaction thereof.

1, the time value and factor.

The time value of transaction content (comprising commodity or service) is relevant with two aspects.At first be relevant to transaction content itself, transaction content self due to the time sex-limited, as the shelf-life, periodically, dull and rush season, seasonal, along with time increment or devaluation etc., the transaction content generation time is worth; Next is relevant to the transaction content production process, and this comprises two processes, the firstth, and the time value that transaction content produces in process of manufacture is as the characteristics in the manufacturing batch in production run, process-cycle and time limit etc.; Second results from the process of exchange of transaction content, as transportation batch, order quantity, stock, alternative product seller's competition etc.

No matter which type of factor generation time is worth, the present invention only need consider following three kinds of situations to the calculating of the time value:

(1), the time value that produces because of the time limit.

The generation in transaction time limit derives from the singularity aspect of transaction content self, as product of foodstuff, fresh goods, medicine, daily use chemicals class etc., stronger time sex-limited requirement is arranged, generally the shelf-life with commodity shows, it may be also the process from production and trade, as the batch of the batch produced, transportation, produce setup time etc., dispatch a car the time limit as the operation of motor passenger vehicle, the food materials in dining room are bought and are made and prepare.

In this case, suppose at a time t ₀Be the last time limit of transaction content, t ₁Be that reality strikes a bargain the time, so, the conclusion of the business time within the time limit, i.e. t ₁≤ t ₀The time, the price of transaction content is P ₀, as time overstepping the time limit, the i.e. t of striking a bargain ₁〉=t ₀The time, the price of transaction content is p ₁, usually, p ₁≤ p ₀

Due to the last time limit t of distance ₀Nearer, the seller bears because the risk of overstepping the time limit is just larger, so generally, if the buyer confirms to buy more in advance, seller's risk will be less so, is worth so the seller just can obtain the regular hour.At this moment, the seller can sell this time value, and the price of this time value can increasing along with acknowledging time in advance.

(2), the time value because periodically producing.

Periodically equally may be from the characteristic of transaction content itself, the difference as agricultural product can occur being worth with the variation in season also can from producing and process of exchange, also can be worth difference with transaction appearance in season as air-conditioning series products, different clothes.

Because of the time value that periodically produces, in the calculating of its value considers mainly the real trade time is between what periodic region, according to different transaction contents, can may have a plurality of time intervals in same period, the price in different intervals is all not identical, in order to simplify, the present invention only considers to have two kinds of different price ranges, and is a kind of for interval at ordinary times, is made as (e, f), establish t ₁For reality strikes a bargain the time, if t ₁∈ (e, f), the price of transaction content is P ₁, interval when the second is light, be made as (j, h), work as t ₁During ∈ (j, h), the price of transaction content is α P ₁, wherein 0＜α＜1, confirm that the time value that exchange hour t produces constantly is (1-α) P ₁

(3), because of in batches and prepare the time value that produces.

In batches and the time value of preparing mainly result from and produce and bargain link, the preparation of producing or selling has great significance to the seller, exchange hour as early as possible can make the seller can not cause loss because of the deficiency of preparing or excess.

If t ₀For preparing start time or batch node time, t is exchange hour, as t≤t ₀The time, the time value of its generation is mainly because making thinner of fixed cost obtains.

When supposing this transaction content production or transaction, fixed cost is C, and number of transaction is M,, and at t≤t ₀The time, increasing a transaction, average unit cost is reduced to:

$\frac{C}{M}-\frac{C}{M+1}=\frac{C}{M(M+1)}$

The cost that reduces thus is the time value.

2, the characteristic of the time value.

When the commodity that the time value and other had use value and can satisfy certain effectiveness of people were treated equally, due to the characteristic of the time value self, it had the advantages that to be different from other commodity, and concrete characteristics are as follows:

(1), the time value do not possess the characteristic that marginal contribution is successively decreased, and is specific as follows:

(a), supply has no elasticity: the quantity delivered of time is changeless, under any circumstance can not increase, also can not reduce.

(b), can't accumulate: the time can be by the savings storage unlike manpower, financial resources, material resources and technology, no matter be willing to be unwilling, we are necessary consumption time, so we can't throttling.

(c), can't replace: any one activity all depends on piling up of time, and in other words, the time is any movable indispensable basic resources, and therefore, the time can't replace.

(d), can't be lost and found again: the time can't be lost and found again as lost article, and it can be lost forever once lose, and has spent money, still can earn back, if but spent freely the time, anyone is unable retrieving.

So the value that is produced by the time does not possess the marginal contribution production decline law of general goods, the rule of its transaction and method also are different from the pricing method of general goods.

(2), the time value has two-way homogeneity.

The exchange of general goods is in fact the exchange to different actual utilitys, that is to say, both parties are different to the actual utility of the content of transaction, but because the time value is different from the transaction rule of general goods, so the time value is consistent for the actual utility of both parties, namely for the seller's the effectiveness that has, have too for the buyer, they often in the same way.

(3), the time value has asymmetry.

Although the time value has same tropism for both parties, but, for different concrete transaction content and process of exchanges, the degree of its effectiveness can be different, and the effectiveness that the time value produces is on amount, asymmetric, this asymmetry has consisted of theoretical foundation of the present invention just, makes the time value have tradable prerequisite, if the time value of both parties equates, perhaps both not significantly differences, so just lost the prerequisite and the condition that exchange.If any the commodity of quality guarantee period, purchase early not only has the seller falls the low-risk time value, for the buyer, has and falls equally the low-risk time value, and they are not only consistent on direction, and quantitatively also identical.

The time value that produces due to the characteristic of transaction content self is consistent often for both parties, namely not only identical on direction, and quantitatively also basic identical, the time value that produces in process of exchange and production run, both parties can produce difference, at this moment, the buyer's the time value does not have or is not obvious.

It is constructed that commodity reservation transaction system of the present invention just is being based on this basic time value characteristic, and model discussed below is to be based upon on the not free value of the buyer or unconspicuous condition.

3, two indispensable elements of time value realization.

(1), the transaction content relevant information knows in advance.

Before confirming in advance, if the buyer can not have sufficient understanding to relevant informations such as the content of transaction, transaction value, Payment Methods, methods of shipment, the buyer just can not confirm in advance so, and the seller's the time value can't realize.The buyer is more abundant to the relevant information understanding, and the seller's the time value could more be easy to realize.Certainly, in the understanding process to information, can relate to the trusting degree to institute's Information, degree of belief is higher, more helps the realization of the time value.

(2), the personalization of demand.

If the demand that the buyer is with no personalization, the customization in advance that the seller can mass, thus the buyer can obtain instant transaction content in the time of needs at any time, thus just there is not the described time value.

4, time value computation model.

(1), the calculation of price model of the time value.

although the existence of the time value is a basic fact, but, rational to its row owing to lacking, system, clear and definite statement and the transaction platform that builds use, so do not consider substantially that in traditional marketing method with take ecommerce as the network selling on basis the time value is for the impact of marketing process, for the interests that can realize both parties in marketing process maximize, at first will build one reasonably, system, clear and definite time value computation model and computing method, below to the present invention is directed to the mathematics computing model that the time value builds.

The generation reason of the time value also can be divided into following two classes: the one, and the cost of transaction content increases with the postponement of exchange hour, and the value of transaction content itself does not have to change or compare variation with the increase of cost very little, as the formed cost of manufacturing batch, process-cycle, time limit due to production and process of exchange, the value that another kind of situation is commodity reduces with the conclusion of the business time retardation, as the time sex-limited value reduction that produces of commodity self.

For the time value that the first situation produces, only meaningful to the seller, and there is no actual value for the buyer, so this value is to realize by buying for the seller.

The time value that second case produces, because the while has same value for the buyer, so, be that the seller can't realize, therefore, the present invention only considers that value of reality that the first situation produces.

The time value that produces for above-mentioned the first situation, referred to as the attainable time value, although irrelevant with the buyer, but whether it realizes but depending on fully the buyer's selection, so, the time value that can realize is regarded as the commodity of being controlled by the buyer, these commodity for the buyer without any meaning, any value of tool not.If both parties are regarded as a game of both parties to the transaction of the time value, according to game theoretic principle, the seller needs only non-vanishing to the price of the time value, and the buyer can accept so.Therefore, price to the time value depends on the seller fully, and the seller can consider from two factors the price of the time value, the factor of the first self, that is to say to make as far as possible the buyer confirm as early as possible to buy, thereby make own time value maximum, it two is factors of rival, but for selling similar commodity or the commodity of phase trans-substitution, the rival is by another factor of consideration when the time value fix a price to the purchase of the time value.But, because the commodity between different rivals, service etc. are larger on the buyer's impact, so, a little less than the impact relatively of the time value, when being fixed a price, the time value need not to consider emphatically.

In order to make discussion more rigorous, represent the price of the time value with p, t represents that the trade confirmation distance allows the time interval of confirming the latest, and t=0 represents that the seller allows acknowledging time the latest, confirms when being later than t=0, and the time value is 0, i.e. p=p ₀, p ₀Price for present deal.T represents that the seller allows acknowledging time the earliest, and at T constantly, the time value is maximum, but transaction value can not be lower than the lowest price of seller's identification, and this price minimum is the cost of transaction content, is denoted as ν, and at this moment, p is the function of t, and t ∈ [0, T], p ∈ [ν, p ₀].

Thus, the time value of transaction content can be expressed as: p ₀-p (t) is denoted as V _t, that is:

V _t=p ₀-p(t)；

V _tBeing the function of t, furtherly, is the monotonically increasing function about t, that is to say, and trade confirmation and real trade time advance more, the time value is just larger.

Corresponding to the instant price of different transaction contents, V _tNot identical yet, so, V _tP ₀Function, be about p equally ₀Monotonically increasing function, that is to say, the instant price of transaction content is larger, the time value is just larger.

Therefore, this present embodiment is determined as drag:

V _t=f(t，p ₀)，

Wherein, t ∈ [0, T]

This function possesses following characteristic:

$\left\{\begin{array}{c}\frac{{\&PartialD;v}_t}{\&PartialD;t}\&GreaterEqual;0\\ \frac{{\&PartialD;v}_t}{{\&PartialD;\mathrm{<figure-callout\; id="0"\; label="p"\; filenames="130312114444.png"\; state="\{\{state\}\}">p</figure-callout>}}_0}\&GreaterEqual;0\end{array}\right.$

(2), the best price function of the time value.

By upper, the value of certain transaction content is p, and the time range that transaction is confirmed in advance is [0, T], concludes the business so at moment t(t ∈ [0, T]) demand be:

d=a-bp-ct；

P is the function of t, below is denoted as p(t),

Wherein, a is the potential demand of transaction, b be demand about the elasticity of price, c is demand about the transaction elasticity of pre-set time, these parameters determine by transaction content, are the build-in attributes of transaction content.

For the seller, its target is for obtaining maximum return, and the cost that we establish transaction is ν, and maximum trading volume is D, that is to say that trading volume is limited under D, so, following mathematical model is arranged:

In order to determine the expression formula of above-mentioned p, order:

$\underset{0}{\overset{t}{\&Integral;}}(a-\mathrm{bp}-\mathrm{ct})\mathrm{dt}=Z\left(t\right)---\left(1\right)$

Obviously, Z(0)=0, and:

$\underset{0}{\overset{T}{\&Integral;}}(a-\mathrm{bp}-\mathrm{ct})\mathrm{dt}=D=Z\left(T\right)$

(1) formula is carried out differential:

$\frac{\mathrm{dZ}\left(t\right)}{d\left(t\right)}=a-\mathrm{bp}-\mathrm{ct}$

Therefore, problem (I) is converted into following problem:

$\left(\mathrm{II}\right)=\left\{\begin{array}{c}\mathrm{Max}:\mathrm{\&Pi;}=\underset{0}{\overset{T}{\&Integral;}}(p-v)(a-\mathrm{bp}-\mathrm{ct})\mathrm{dt}\\ \mathrm{Subjectto}:a-\mathrm{bp}-\mathrm{ct}-\frac{\mathrm{dZ}\left(t\right)}{\mathrm{dt}}=0\\ Z\left(0\right)=0,Z\left(T\right)=D\\ p\left(0\right)={\mathrm{<figure-callout\; id="0"\; label="p"\; filenames="130312114444.png"\; state="\{\{state\}\}">p</figure-callout>}}_0,p\left(T\right)=v\end{array}\right.$

(I) be of equal value with (II) problem, be constructed as follows function:

$H=(p-v)(a-\mathrm{bp}-\mathrm{ct})+\mathrm{\&lambda;}[a-\mathrm{bp}-\mathrm{ct}-\frac{\mathrm{dZ}\left(t\right)}{\mathrm{dt}}]$

Wherein, λ is Lagrangian.

Eulerian equation is:

$\frac{\&PartialD;H}{\&PartialD;p}-\frac{d}{\mathrm{dt}}\left(\frac{\&PartialD;H}{\&PartialD;\stackrel{\&CenterDot;}{p}}\right)=0,$

Wherein,

That p is about the derivative of t.

Due to Z(t) be only the function of t, therefore:

$\frac{\&PartialD;\left(\frac{\mathrm{dZ}\left(t\right)}{\mathrm{dt}}\right)}{\&PartialD;\mathrm{<figure-callout\; id="0"\; label="p"\; filenames="130312114444.png"\; state="\{\{state\}\}">p</figure-callout>}}0,$

$\frac{\&PartialD;\left(\frac{\mathrm{dZ}\left(t\right)}{\mathrm{dt}}\right)}{\&PartialD;\stackrel{\&CenterDot;}{p}}0,$

Therefore, (II) exist the necessary condition of extreme value to be:

$\frac{\&PartialD;\left[(p-v)(a-\mathrm{bp}-\mathrm{ct})\right]}{\&PartialD;p}+\mathrm{\&lambda;}\frac{\&PartialD;(a-\mathrm{bp}-\mathrm{ct})}{\&PartialD;p}=0$

Thus, draw:

-2bp+a-ct+bν-λb=0

Arrange:

$p=\frac{a-\mathrm{ct}+(v-\mathrm{\&lambda;})\mathrm{<figure-callout\; id="2b"\; label="b"\; filenames="130312114444.png"\; state="\{\{state\}\}">b</figure-callout>}}{2b}$

$=\frac{a-(v-\mathrm{\&lambda;})\mathrm{<figure-callout\; id="2b"\; label="b"\; filenames="130312114444.png"\; state="\{\{state\}\}">b</figure-callout>}}{2b}-\frac{\mathrm{<figure-callout\; id="2b"\; label="c"\; filenames="130312114444.png"\; state="\{\{state\}\}">c</figure-callout>}}{2b}t---\left(2\right)$

Due to, p (0)=p ₀, can obtain,

$\mathrm{\&lambda;}=2{\mathrm{<figure-callout\; id="0"\; label="p"\; filenames="130312114444.png"\; state="\{\{state\}\}">p</figure-callout>}}_0+v-\frac{a}{b}---\left(3\right)$

With (3) substitution (2) formula, can obtain:

$p=p_0-\frac{\mathrm{<figure-callout\; id="2b"\; label="c"\; filenames="130312114444.png"\; state="\{\{state\}\}">c</figure-callout>}}{2b}t$

Due to, p (T)=ν can obtain thus:

$T=\frac{2b}{c}(p_0-v)$

So far, obtain the cost function of the time value and Best Times interval.

(3), consider the calculation of price of time value factor.

The present invention just the time value as the influence factor in process of exchange, thereby revise the price of transaction content, thus, also just realized the transaction of the time value.

Time value v _t=p ₀-p (t), the best price function of the time of deriving according to the front has:

$v_t=p_0-p\left(t\right)=\frac{\mathrm{<figure-callout\; id="2b"\; label="c"\; filenames="130312114444.png"\; state="\{\{state\}\}">c</figure-callout>}}{2b}t$

T ∈ [0, T] wherein, b be transaction content about the elasticity of demand of price, c is transaction content about the elasticity of demand of acknowledging time in advance, only the attribute to transaction content self is relevant for they, the concrete numerical value of b, c can obtain by two methods.

First empirical method, namely the seller is according to the marketing experience of self, by observation price or the variation of acknowledging time in advance, the impact situation of carrying out of sales volume is calculated, in order to be problem reduction, we generally can first fix a variable, observe the variation of an amount to the situation that affects of sales volume.In order to obtain the value of b, we shift to an earlier date acknowledging time t ∈ [t as us ₁, t ₂] (t ₁, t ₂Be constant, t ₁-t ₂Be smaller real number) the minizone in, the situation of change of sales volume relative price.Suppose that price is from p ₁Change to p ₂, observe this moment, and sales volume is from d ₁For changing to d ₂, we can calculate price elasticity b by following formula so.

$b=\frac{p_2-p_1}{p_1}/\frac{d_2-d_1}{d_1}$

Equally, we also can fixed price in a certain scope, by observing sales volume with the situation of change of acknowledging time in advance, calculate time elasticity.

$c=\frac{t_2-t_1}{t_1}/\frac{d_2-d_1}{d_1}$

It two is statistic laws, utilizes knowledge of statistics, adopts the method that returns to obtain the estimated value of parameter b, c.When we have many sales datas, can obtain with the method for parameter estimation comparatively accurate elasticity coefficient value.Function according to demand:

d=a-bp-ct

We establish a, b, and the estimated value of c is respectively

C calculates b with the binary linear regression analytical approach, the estimated value of c.

According to above computation process, obtain time value V of the present invention _tThe Optimal calculation formula as follows:

V _t=ct/2b；

Wherein, t=T _t-T _x-T _min,

B is that transaction content is about the elasticity of demand of price;

C is that transaction content is about shifting to an earlier date the elasticity of demand of acknowledging time;

T _xBe the trade confirmation time;

T _tBe the reservation exchange hour;

T _minFor minimum is preengage pre-set time.

According to above computing formula, system of the present invention calculates the trade confirmation time T in accordance with the following steps _xThe time value V of moment commodity _t:

(1), read the trade confirmation time T _x

(2), read reservation exchange hour T _t

(3), read minimum reservation T pre-set time _min

(4), computing time parameter t, t=T _t-T _x-T _min

(5), read maximum reservation T pre-set time _max

(6), judge whether t≤0, be time value V _t=0, algorithm finishes, i.e. the final knock-down price P of commodity _X=P, otherwise the step below carrying out;

(7), judge whether 0≤t≤T _max, be according to time value V _tOptimal calculation formula (V _t=ct/2b) be worth V computing time _t, final knock-down price P _X=P-V _t, otherwise V _t=P-V, i.e. final knock-down price P _X=P-V _t=P-(P-V)=V, i.e. final knock-down price P _XBe the lowest price V of commodity, algorithm finishes.

In transaction, after seller's electing sale content, system of the present invention carries out in accordance with the following steps:

(1), the seller judges according to transaction content whether commodity possess the time value, otherwise transaction, i.e. End-price P in a conventional way _x=nominal price P is to carry out following step;

(2), the seller determines that whether the time buying is worth, otherwise transaction, i.e. End-price P in a conventional way _x=nominal price P is to carry out following step;

(3), the seller is according to transaction content select time value models, i.e. the computing method that are worth of select time;

(4), the seller inputs nominal price P, the lowest price V of commodity, minimum reservation T pre-set time in system _min, maximum reservation T pre-set time _max, price elasticity of demand b, the elasticity of demand c of acknowledging time in advance;

End-price computing method and the futures business of system of the present invention are essentially different.The essence of futures business is following certain a kind of prediction of price constantly of transaction content, and can not go to consider the length of this time, more do not calculate the value that this time itself has, essence of the present invention is the transaction to the time value itself, although the price of this value will be somewhat dependent upon transaction content itself, but the basic reason of the generation of this value comes from confirms exchange hour and the difference of real trade between the time.

End-price computing method of the present invention also are different from the marketing mode that kills second of present a lot of marketing classes website adopting, kill and say in essence a kind of promotion strategy second, it can not consider to consist of this, and the key factor time value of invention, its price is according to the consideration of seller for sales promotion, but not is the transaction to the time value.

transaction system of the present invention and existing B2B, B2C, C2C, the network selling platform combination of marketing class such as purchase by group, need not change original network platform, only need to increase an option in original purchase option gets final product, system of the present invention is more reasonable with the time value, system more, clearer and more definite is explained, and apply in actual internet business, make and be ready sell the buyer of the own time value and be ready with the seller that certain price is bought the buyer's time value wish of reaching an agreement with certain price, system calculates the corresponding time value according to the computing method of setting, price deduct the time value in the nominal price of commodity after is final knock-down price, both parties can be benefited from it, can promote the development of internet business.

The computing method of the present embodiment are for the impact of the clearer explanation time value on commodity price; according to different item property; the time value, End-price also had other different computing method; the modeling of the present embodiment and computation process; can not limit protection scope of the present invention; so long as modification and the variation done according to protection scope of the present invention, within still belonging to the scope that the invention contains.
