METHOD AND SYSTEM FOR PURCHASING GOODS BY LOTTERY, AND METHOD AND SYSTEM FOR PURCHASING GOODS BY LOTTERY AND JOINT USING THEREOF}

The present invention relates to a method and system for lottery lucky purchase of goods using the Internet, and a method and system for lottery joint purchase using the same. In more detail, in the online e-commerce using the Internet, the discount factors generated due to the reduction of the distribution process, the OEM purchase, the pre-purchase purchase, the joint purchase of the goods, and the collective purchase are prescribed instead of the discount sale. The discount factor is a lottery for selecting a winner by selecting a winner by selecting a winner for a predetermined unit of clients who purchased the prize. Luck relates to a method and system of purchase.

The present invention relates to a lucky draw method and system for lottery purchase in online e-commerce, which is sold by dividing the same product into various sales units in order to respond to various purchase desires of a buyer client who wants to purchase a product.

Furthermore, as a method for realizing the above-mentioned lottery lucky purchase method, a new lottery common lucky purchase method and system using B-to-B commerce online co-purchase form between a producer client and an operator of a commodity server is provided. will be. More specifically, the producer client can register and sell his own product directly to the product server sold by the above-mentioned lucky draw method, with the approval of the operator of the product server, and the client as a consumer to the product server. When you make a purchase, you will be given a unique lucky number.When you reach the target sales volume, you will be drawn in a fair manner to give the winning client the cash of the purchase price or more. Grants will be directed to a lottery joint luck purchase method and system.

Currently, with the generalization of the Internet, the online shopping population using the Internet is gradually increasing.

Meanwhile, the joint purchase method and the modified form of the joint purchase method are widely popular in not only online e-commerce but also offline commerce because the product can be purchased at a low price.

9 (a) and 9 (b), a typical joint purchase method and a sliding joint purchase method widely used on the Internet will be briefly described.

Fig. 9 (a) is a diagram showing an example of a typical joint purchase method in a conventional off-line commerce, and Fig. 9 (b) is a diagram showing an example of a sliding joint purchase method in an online commerce.

As shown in FIG. 9 (a), a typical joint purchase method is one million won, which is the market price of a product when the client 10 goes to the store 70 alone and purchases a product (for example, a refrigerator). You can buy and give. On the other hand, when a meeting of clients 10, for example, a group of 10 or 20 people purchases a product (for example, a refrigerator) as a group, they can go to a store and negotiate a price. As shown in (), it can be purchased for 950,000 won per refrigerator. This typical co-purchasing method is not only difficult to recruit a large number of people who want to purchase the same product, that is, a large number of clients, but also a price negotiation process is not effective.

This typical co-purchasing method has led to the development of the Internet, which has attracted a large number of clients who want to purchase the same product, and the modified co-purchasing method (hereinafter, referred to as sliding co-purchasing method) currently practiced on the Internet is prevalent.

As shown in Figure 9 (b), the sliding joint purchase method using the Internet, the Internet portal operator or the online shopping mall 80 and the manufacturer 60 by the contract, the specifications of the jointly purchaseable goods or the price at the joint purchase, etc. Presenting on the Internet to collect clients who want to purchase the same product. Specifically, if 10 people co-purchase the product A, the product price is 155,000 won, if 30 people co-purchase the product price 150,000 won, and if 50 people co-purchase the product price 145,000 It is a sliding co-purchase method where the price decreases as more co-buyers are sold.

Using such a joint purchase method, there is an advantage that consumers can buy the goods needed at a lower price for the same product.

In performing the online commerce by the above-described sliding joint purchase method as shown in Fig. 9 (b), the transaction between the producer and the operator of the online shopping mall, that is, the producer requests the sale of the product to the online shopping mall, The decision-making process is performed by off-line commerce, and online commerce is performed only between an online shopping mall and a client (consumer). Therefore, strictly speaking, an incomplete form of online joint purchase is being made. Therefore, there is a situation in which the co-purchase such as the difference between the photo data presented in the online shopping mall and the actual product and the sale of the old model occur.

This detriment is caused by the commerce between the online shopping mall and the client (B-to-C :) without the commerce between the producer and the online shopping mall (B-to-B: intercompany transactions, hereinafter simply referred to as B-to-B). It is believed to occur because there is no business-to-consumer transaction, hereinafter simply referred to as B-to-C.

Therefore, when registering and reviewing a large number of products, there is a problem in the number of people and management in the operation of the online shopping mall.

In view of the above-described problems, the present invention, in the online e-commerce using the Internet, instead of the sale of the discount factor generated due to the reduction of the distribution process, the product is divided into predetermined units and sold at the market price. The discount factor is to provide a lottery lucky purchase method and system for selecting a winner by selecting a winner for a predetermined unit of clients who have purchased a prize, and providing the winner with a prize including cash corresponding to the prize price.

Another object of the present invention is in the online e-commerce using the Internet, the producer client can register or directly register their products to the commodity server, the client is connected to the commodity server to buy the goods lottery common luck To provide a purchase method and system.

Another object of the present invention is to provide a lucky number to the client within the number in the number of recruitment, when the client connects to the prize server, retrieves the prize with the probability of winning and the number of recruits, purchases the prize, and the payment is completed If the client chooses directly and the target sale of the same product is made, the lucky number will be drawn within the designated period and the winner will be given the same prize or more corresponding cash or equivalent of the prize to maximize the customer attraction effect. To provide a lottery common luck purchase method and system.

Still another object of the present invention is to provide a lucky draw method and system for lottery purchase in online e-commerce in which a variety of sales units are sold to the same product in order to respond to various purchase needs of a buyer client who wants to purchase a product. will be.

Another object of the present invention is not to discount the product as much as discount factors such as distribution margin, logistics cost, OEM purchase, pre-purchase purchase, joint purchase of goods, collective purchase, etc., but to the client who purchased the product As a method of returning, it is to provide a lottery common luck purchase method and system for maximizing the expansion effect of customer incentive by displaying information about the prize, the probability of winning, the number of sold, etc. on the search screen of the prize.

Another object of the present invention is to produce a product on the producer side without sacrificing a margin, such as discount of the product, and the client can purchase other products for savings such as distribution margin generated in the distribution process through a common luck purchasing method and system. The present invention aims to provide a lottery common luck purchase method and system that can induce consumption promotion, prevent conflicts in offline and online commerce, and establish a distribution order.

It is still another object of the present invention that when a client purchases a prize, if the winning probability provided is won in a joint lucky purchase lottery with a high chance of winning, such as 1/2 to 1/10, the corresponding price of the purchased product or more It is to provide a lottery common luck purchase method and system for obtaining good luck to receive cash or the like.

Another object of the present invention is that when a client purchases a product, about 10 of the price of the purchased product, even if the winning probability provided is not won in the lottery common luck purchase lottery of as high as 1/2 to 1/10 It is to provide a lottery common luck purchase method and system that a client can expect a discount of a product in order to receive a cash amount or a prize corresponding to a certain percentage of% and consequently to purchase a product.

(Example 1)

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3.

1 is a view showing a schematic system configuration for realizing a good luck purchase method of goods according to the present invention.

In Fig. 1, reference numeral 10 denotes a user who uses a mobile telephone, a personal digital assistant (PDA), or a personal computer terminal capable of internet as a client. In addition, reference numeral 100 is a commodity server capable of realizing the online purchase of goods using the wired or wireless Internet according to the present invention.

Here, the commodity server 100 is composed of a plurality of databases. For example, the product server 100 may include a member information database 111 for managing registered member information, a product information database 112 that stores price and detailed information of a product, a sale unit when a lucky purchase of a product, or a winning The database includes a plurality of databases such as a lucky number extraction database 113 corresponding to a probability and a winning probability, a lottery database 114 storing various lottery games, puzzle quiz methods, and the like.

Here, the database for implementing the lucky purchase system of the present invention is basically designed in a new form as follows.

First, the general merchandise purchase system generally includes a database of member information, merchandise, and the like. However, the lucky purchase system of the present invention provides a lottery database for prizes in order for a client to realize a lucky purchase provided after purchasing a product. Should include more. The prize database defines the prize information in order to implement this lucky number lottery, and then uses the SQL-DDL technology and DB schema to define the matters related to the prize (for example, prize details such as 1, winners such as 1). The product is divided into product information and giveaway information using normalization technology.

second. In the lucky lucky system of the present invention, in order to implement a lucky number selection function, a program is implemented by applying a DOM (Document Objection Model) technology of Dynamic Hyper Text Markup Language (DHTML) and a user-defined function and dynamic text generation technology of Java Script. By doing this, the lucky number selection software is executed on the user's client and the load on the service provision server is reduced. The lottery ratio setting method is designed to be used unlimitedly without limiting the lottery ratio.

Third, in the lucky draw system according to the present invention, when the lucky number is selected, the already selected lucky number cannot be selected again, and the DB locking technology is applied to the lucky number already selected so that the lucky number cannot be duplicated. A lucky number duplicate prevention system was developed and applied. Therefore, when selecting a lucky number, even if several people select the same number at the same time, the duplicate number is not duplicated even if the first lucky number is selected, and only the user who selects the first lucky number is given a choice.

Fourth, the product database of the lucky purchase system of the present invention is designed such that the number of clicks of a product is stored in the product database whenever the displayed product is clicked by a client using SQL-DML technology. It has an automatic analysis function of real-time user response that automatically changes the position of the product displayed on the screen according to the number of clicks.

In addition, by designing such a database, the client 10 who wants to purchase a product may simply search for a deadline product, an event product, and the like by sorting the necessary items.

By this new function, the buyer client 10 can naturally know the popular products among many products, and the producer client can use this information as marketing information.

Hereinafter, a luck purchase method in a lucky draw system according to an embodiment of the present invention will be described in detail with reference to FIGS. 2 (a) to 2 (e) and 3.

2 (a) to 2 (e) and 3 is a view schematically showing a lucky purchase process in a lottery lucky purchase system according to the present invention.

In FIG. 2 (a), the product server 100 of the lucky draw system according to an embodiment of the present invention includes a plurality of products (eg, computer supplies) to facilitate a search when a client searches for a product. , Electronics, electronics, children / toys / fancy, precious metals, foods, etc.) and register them and conduct online e-commerce. Of course, other categories or the like may be added or changed according to the type of the product.

For example, on the display screen shown in FIG. The client may provide detailed information on a predetermined product and other information, such as expert advice for selecting a better product or considerations when selecting the product, together with the detailed information of the product.

The selling price of the product using the lucky draw system according to the present invention is a market price that is sold on the market of the same product in principle, and the amount paid when winning the first prize is an amount corresponding to the selling price or more.

The client 10 who wants to purchase a specific product accesses the product server 100 through the Internet and searches for the product. At this time, a refrigerator (for example, product number: 0103-0001) of A company among various products displayed on the screen of the computer terminal is going to be purchased at a price of 1 million won.

A plurality of products are displayed on the screen provided by the product server 100. Each of the various products has a product number, a product name, and a probability (eg, 1/2 to 1/10 depending on the product) of winning a common luck purchase method at the time of purchase, as shown in Fig. 2 (a). For example, when the client 10 selects and clicks a refrigerator of A company, as shown in FIG. 2 (b), the price, detailed information, sales recruitment target number, lottery common luck purchasing probability, and the like of the selected product, The number currently sold is displayed. Here, the currently sold number may be displayed as a number, a symbol, etc., which is to be able to selectively display only the final product is imminent, that is, the lottery is imminent.

Here, the goods are sold by dividing the product into, for example, 2 to 10 units based on the margin rate of each product, and the selling unit is a lucky draw as described below based on the discount factor of the product due to the reduction of the distribution process described above. It is calculated according to the probable probability, and this divided unit becomes the target recruitment number of the product.

Here, the lucky draw probability of the lottery is to select a winner among those who purchased the corresponding product by various lottery methods stored in the product server 100 within a predetermined period after the corresponding product reaches the sales target recruitment number, It refers to the probability of a purchase method that can return the cash corresponding to the prize price to the winner. These probabilities are calculated based on the distribution intrinsic distribution margin and discount factors caused by the reduction of distribution channels. In more detail, for example, if the market price of the refrigerator of commodity A is 1 million won, the margin is 30%, and a discount factor of 30% occurs, the chance of purchasing a lucky draw is allotted 20% of the margin, and the lottery 10% will be allocated to the percentage of prizes offered, including cash provided to each of the 10 clients who do not win. This calculation method is illustrated to explain the lucky draw system of the present invention and is not intended to limit the scope of the present invention. In addition, it should be appreciated that the calculation basis of the calculation method, that is, the winning prize, etc., may be modified in operation of the lucky draw system of the present invention.

For example, if the unit of sale of an item A is 5, the probability of joint good luck is 1/5, and if five people have purchased the item A, one in five of them returns the amount corresponding to the price of the item in cash. I can receive it. In this case, one million won can be returned in cash, and four clients 10 who have not won are provided with one hundred thousand won cash corresponding to about 10% of the commodity price. The remaining 10% may be used as a commission of the operator 110 of the commodity server 100, such as transportation costs, etc. If necessary, the remaining costs, such as shipping costs, may be returned to all clients who have purchased the goods, and the transportation costs may be covered by the costs of advertising revenue, events, and the like according to the operation of the lucky draw system according to the present invention.

In addition, 10% of the cash provided to such a non-winning client is an electronic lottery that provides a certain product to all clients in the product server 100 which is periodically executed within a predetermined period by the client's choice. It may be provided in the form. In this case, the electronic lottery may be provided in the longevity corresponding to cash.

As described above, the lottery lucky purchase system according to the present invention purchases the goods instead of discounting the discount factors due to the reduction of the distribution process of goods, OEM purchase, pre-purchase purchase, joint purchase of goods, and collective purchase Construct a merchandise sales system that returns 100% or more to a client by drawing a draw.

In general, in off-line commerce, the more complex the distribution process of a product is, the larger the distribution margin becomes. In electronic commerce, such distribution margin naturally occurs as a discount factor of products, so that products are discounted and sold. In electronic commerce, in addition to these discount factors, there is a discount factor of products due to OEM purchase, pre-purchase purchase, joint purchase of goods, and collective purchase. In the lottery lucky purchase system according to the present invention, it is possible to purchase goods inexpensively including all possible discount factors, and the difference between the purchase price and the sale price of the goods by cash or the like through the lottery to the client who purchased the goods. It is a principle to offer prizes.

In other words, the lottery lucky purchase system sells a product so that the margin generated can be returned to the client by 100% or more, and induces the customer to generate other forms of profit through this product method. In other words, the system's revenue model can generate revenue from advertising and events targeted at clients using the system, as in most Internet companies.

In conclusion, when the client 10 who has purchased the prize using the lucky draw system according to the present invention wins, he / she can purchase the desired product and, in addition, receive the cash of 1 million won, the worst not win. Even in this case, since the cash corresponding to about 5 to 10% of the product market price can be returned, there is a discount effect corresponding to 5 to 10% more than the market price. Therefore, since it is differentiated from other Internet shopping malls, and many profits are returned to the client and the producer of the product, the attracting effect of the customer is significantly higher than other shopping malls.

In addition, when purchasing a large quantity of goods, for example, a product having a probability of winning 1/5, a product price is 50,000 won, and the prize money provided at the first prize is 45,000 won, for example, 50 You can buy 59 at a price of 2.5 million won or 50 at the same time. If you pay 50 at 43 million won, the price of 43 is 50, you can win 8 prizes and get 360,000 won. It can be seen that the seven items can be purchased at this amount, and the price of the product can be purchased again as a result of this amount of money. Therefore, according to the calculation, 50 pieces can be purchased for 2.12 million won, resulting in a natural discount effect.

In FIG. 2 (c), when the client 10 makes a purchase application in FIG. 2 (b) after a product search, a payment method is selected by credit card, bank transfer, electronic money payment, etc., and payment is performed. do.

In Fig. 2 (d), when the payment is completed, the purchase good luck number of the product is provided or selected. Before and after the lucky number and the client's direct selection, you can enter the information about the delivery of the goods, the address for notifying the result of the lottery, the e-mail address, the delivery address, and the like. Here, the method and selection of the lucky number may be considered in various ways, but the number from 1 to the target sales number or the number from 0 to the target sales number-1 may be sequentially or arbitrarily given or not depending on the order of purchase of the goods. The client can choose it. For example, if the target number of sales is five, that is, the probability of winning is 1/5, a random number up to 1-5 may be randomly assigned or the client may select it. Here, credit card, electronic payment, etc., because payment is performed immediately, it is possible to immediately give or select a lucky number, but if the transfer of funds through a bank account is delayed, the purchase itself is often canceled frequently Therefore, it is desirable to assign good luck numbers after the confirmation of the transfer. However, in the lottery lucky purchase system of the present invention, a client who purchases a product in addition to a unilateral luck grant method may directly select a lucky number, and in the case of a payment method, a lucky number may be first assigned or selected. Be aware of this.

In the lucky purchase system according to the present invention, after the client purchases a product, when the lucky number is selected, the DB locking technology is already selected so that the lucky number cannot be selected again, so that the lucky number cannot be duplicated. The lucky number duplication prevention system was developed and applied to the lucky number. Therefore, when selecting a lucky number, even if several people select the same number at the same time, the duplicate number is not duplicated even if the first lucky number is selected, and only the user who selects the first lucky number is given a choice.

On the other hand, the lottery method is a lottery within a predetermined period, for example, within three days from the point of completion of the target sales in principle based on the database 140 including a fair lottery or quiz, game method and the like.

Here, as the lottery method according to the method proposed in the patent application entitled "Lottery method and system using stock-related index information, method and system for providing lottery service using the same" filed June 2, 2001 by the present applicant, It is thought that a fair way could be achieved without the intervention of the system operator. Therefore, in the present system, fairness was adopted by adopting a lottery method using stock-related index information proposed in the above application.

The result of the drawing is posted on a bulletin board as shown in FIG. 2E to be described later, and the client 10 is individually notified through various communication means such as an electronic mail, a mobile phone, and a text message of a mobile phone.

FIG. 2 (e) is a diagram exemplarily showing a drawing result provided on the bulletin board of the product server 100. FIG.

Here, as shown in FIG. 2 (e), the product number, the buyer, the lottery date, and the winners may be collectively displayed, or may be provided in a searchable state and may be searched at any time.

In the case of winning the lucky draw in FIG. 2 (d), since the client 10 receives an amount corresponding to the purchase price of the joint product as cash or a corresponding prize, the client 10 can purchase the necessary product again or leave the cash as it is. You can request a deposit into your bank account.

Hereinafter, a detailed process of the lucky draw method of purchasing according to the present invention will be described in detail with reference to the flowchart of FIG. 3.

3 is a flowchart illustrating a specific process of the lucky draw method of purchasing according to the present invention.

In FIG. 3, the client 10 accesses the product server 100 of the lucky draw method and system according to the present invention using the Internet and searches for a product (step S10).

In step S 20, the client 10 searches the product database 110 of the product server 100, searches for the product that the client 10 wants to purchase, and purchases the product (FIG. 2 (a)). To FIG. 2 (c)].

In step S30, when the client 10 selects a product and makes a purchase application, and the payment of the product price is completed, the client 10 directly selects the lucky number for the joint lucky purchase lottery according to the present invention or the client directly selects the product. (See FIG. 2 (d)). In this step, contact information for notifying the result of the lottery, for example, an e-mail address and a telephone number, is entered.

(Example 2)

Hereinafter, a lucky purchase method in a lucky draw system according to another embodiment of the present invention will be described in detail with reference to FIGS. 4 (a) to 4 (b) and 5.

In Example 1, for convenience of description, only one winning probability (fixed unit of sale) is provided for one type of product, but in Example 2, various winning odds are presented for the same product. A method (for example, a method in which a probability of winning 1, 1, 3, 1, 100, etc., may be variously provided when a refrigerator is purchased), that is, a method in which sales units may be set in various ways will be described.

The client 10 who wants to purchase a product has various types of purchase desires, and in order to satisfy the desires thereof, it is desirable to satisfy the desires of the plurality of clients 10. This embodiment is to implement a customized lucky purchase form to meet the purchase needs of the various clients 10 as described above to escape from the uniform purchase form or purchase form.

In Example 1, it was explained that the refrigerator has a probability of winning 1 or the like at 1/5 and is sold in 5 units.

In this embodiment, in the method of reducing the discount factor of the same product through the lottery to the client 10 who purchased the product, the discount factor may be divided into various types of sales units based on the total discount factor.

Basically, as in Example 1, assuming that a discount factor of a product including a distribution margin of a refrigerator having a price of 1 million won is 30%, the refrigerator is divided into five units based on a discount factor such as distribution margin. It sells, and the probability of winning 1st prize is 1/5.

For example, in FIG. 4A, a refrigerator may be divided into three units, four units, five units, ten units, 50 units, and 100 units. That is, when the refrigerator is divided into three units and sold, the winnings, such as one, can be 90% of the total discount factor generated when all three units are sold. In the case of selling in 10 units, the first prize is 300% of the total discount factor that occurs when all 10 units are sold.In the case of selling in 100 units, the first prize is 10 The total amount of the discount factor that occurs when all the cars are sold is 3000%.

In FIG. 4 (a), the same product may be displayed repeatedly by changing only the winning probability and the winning prize, such as 1, and as shown in FIG. 4 (b) in consideration of the limited space of the web browser, on the display screen for one product. If the client 10 clicks on the probability of winning, it is possible to directly display the sale unit currently being sold. In addition, the conventional database design technology is designed to display the first prize in conjunction with the winning probability.

Therefore, when the client 10 clicks and selects a predetermined winning probability when searching for a product, the corresponding winning prize is displayed. For example, as shown in FIG. 4B, when searching for a refrigerator, a predetermined probability of winning may be selectively searched, and a corresponding winning prize, such as 1, may also be searched.

5 is a flowchart showing a specific process for the lottery lucky purchase method according to this embodiment.

The lottery lucky purchase method according to this embodiment is the same as or similar to the method shown in FIG. 3, and further includes a step (S 25) in which the client 10 selects a winning probability after purchasing an item.

According to the lottery lucky purchase method according to the present invention, when selling by dividing into a variety of sales units there is an advantage that can respond to a variety of customer's desire to buy, as well as easily accessible to clients who want to buy a large quantity, It can be easily applied to B-to-B joint sales and / or B-to-B joint purchases between producer clients and buyer clients.
