 Other features and advantages of the present invention are apparent from the detailed description which is either directly described or described below in the preferred embodiments.

Recently, with the development of science and technology, a commerce method using online media such as communication sales and the Internet has emerged as a new product purchase method. An example of a space where such commerce takes place is a TV home shopping channel or an internet shopping mall. Unlike the traditional store visit commerce, the basic feature of online commerce is that a store for a product does not need to exist physically. .

 The biggest advantage of the above-mentioned online commerce method is that the physical space for product display and sale does not need to exist so that the store maintenance cost for product display and storage can be reduced, and the time and space for commerce are reduced by reducing the stage of product distribution. Is relatively free.

 On the other hand, if the existing e-commerce method is classified based on the price setting method of the commodity, it can be divided into a fixed price method, a variable price method such as auction, reverse auction.

  Here, the fixed price method refers to a method in which transactions can be made only at a reconnaissance price determined by an internet shopping mall and negotiation of price is almost impossible. On the contrary, the variable price method is a price setting method in which the price of the product is not determined and thus the price negotiation is possible between the seller and the buyer, and the final price of the product is determined by various factors.

 A representative example of a commerce method in the form of variable pricing is auction. Those who want to buy a certain item will participate in the bidding while raising the price. This electronic commerce method is a method of purchasing goods made mainly by a seller. That is, in the auction, generally, a seller of goods is placed on an intermediary server for sale using the Internet, and buyers present a price to determine a successful bid price. Therefore, in such an auction, the seller predominantly determines the type, condition, price of the goods purchased, and the like.

 Compared to the existing e-commerce schemes, the buyer-led e-commerce scheme has emerged. This type of auction is called reverse auction. US Patent No. 5,794,207 is one example. The method according to this patent relates to a commerce method in which a seller who can satisfy this condition provides a product by receiving a successful bid when the buyer presents the purchase condition.

 The advantage of the conventional buyer-centered Internet commerce method is that the buyer can purchase the goods on the condition that the buyer wants, the buyer's offer to the seller is passed to a number of sellers can easily know the products that the seller needs to buy and also the same product Even if the buyer can have a favorable condition, he can make a condition that he can serve. However, there is a paradoxical aspect of such a buyer-centered commerce that even if a seller wants to obtain and sell a new product that the buyer does not know. In addition, due to the recognition that the existing reverse auction method is unilaterally buyer-oriented, the reverse auction is often not established even when a buyer requests a purchase.

 An example of a similar type of electronic commerce is US Pat. No. 6,055,519. The model disclosed in this patent relates to a bargaining in a general store, i.e., a system that implements a method in which a buyer and a seller negotiate a purchase on the Internet. This bargaining system allows buyers and sellers to negotiate with each other about the quantity, price, delivery date, etc. of a particular product, enabling buyers to actively purchase the product. However, this method has the advantage that buyers and sellers can respect each other's interests through negotiations, but there is a disadvantage that it can consume manpower and time and complicated the process for mutually satisfactory negotiations.

 In addition, although all existing e-commerce had convenient conveniences in commerce, they did not provide the opportunity and fun to get to know various people through traditional store visiting commerce. Therefore, those who feel bored and marginalized when doing commerce through e-commerce may prefer traditional store visit.

The present invention has been made to solve the problems of the e-commerce method according to the various types of prior art exemplified above, so that both the buyer and the seller is the center of the e-commerce in the way that the existing commerce was the buyer or seller centered By using the auction method and reverse auction method of to provide a device for implementing a purchase and sales method completely different from the existing e-commerce method.

According to the present invention, a category containing purchase information is generated by a purchaser submitting a purchase proposal to an intermediary server in an internet e-commerce, and a seller has a subordinate concept category containing sales information by submitting a bid to the seller. They allow buyers to obtain the latest market trends and information in real time, thus preventing them from dealing with unnecessary goods in advance. Also, not only the buyer but also other buyers can identify categories of sub-concepts created by sellers' bidding. It enables buyers to bid on sellers who offer satisfactory prices and services, so that buyers can purchase the products they want according to their own shopping styles, and even if the sellers do not win the bid, Can sell And so.

The present invention can also generate a category containing the information of the product by submitting the product information (commodity proposal) to the intermediary server, as well as the buyer, from which only the seller itself can not obtain other sellers or other buyers To let buyers know their unique products. In the category, a sub-concept category containing sales information is generated by not only the seller but also other sellers submitting at least one proposal to an intermediary server. To provide more reasonable prices and services.

Another object of the present invention is to provide a place of purchase that enables the buyer to reduce physical and mental fatigue when shopping and to purchase a product, and allows the seller to sell the product without operating a separate store. It is to promote electronic commerce by laying the ground for sales and promoting mutual transactions.

Yet another object of the present invention is to enable buyers to purchase goods at better prices and services by having multiple sellers offer competitive prices and services for the goods.

Another object of the present invention is to provide a chance and fun to get to know a variety of people through the mini-homepage service provided by the intermediary server, even if you do not know each other face to face friendship between users through e-commerce In addition, it is possible to encourage each other to participate in a joint purchase offer, which is recruiting or participating, so as not only to enjoy the user's enjoyment and friendship, but also to improve the sales of the sellers.

 Referring to the drawings shown by the reference of the above method, FIG. 15 shows a reverse auction system according to an embodiment of the present invention. This reverse auction-auction system includes a personal computer (1504, 1506, 1508) used by a buyer, a personal computer (1510, 1512, 1514) used by a seller, one or more intermediary servers (1502a), a group of web servers and a database server ( 1502b, 1502c and the Internet 1500 that interconnects these personal computers 1504, 1506, 1508, 1510, 1512, 1514 and servers 1502a, 1502b, 1502c.

 Buyer personal computers 1504, 1506, 1508 and seller personal computers 1510, 1512, 1514 may be self-contained personal computers. Alternatively, the buyer personal computers 1504, 1506, 1508 and the seller personal computers 1510, 1512, 1514 may be interconnected via the Internet of the buyer or seller company.

 In FIG. 15, the functions performed by the mediation server 1502a, the web server 1502b, and the database server 1502c may be implemented in a single server unit, but these servers are shown separately to emphasize the individual functions of these servers. have. The intermediate server 1502b may include a computer having a high speed data processing function. The web server 1502b and the database server 1502c may include a computer equipped with software for running a web site and a database system. For example, the web server 1502b may be a Windows XP server or a static HTML page generated to support the functionality of the user interfaces presented below, and model the data held in the database server 1502c. It may also include software such as the Microsoft Internet Information Services used. Web server 1502b may also include software to replicate data between database server 1502c and intermediary server 1502a.

Database server 1502c may be implemented by running an Oracle SQL server in a separate Windows XP server.

 In the system implemented in FIG. 15, the mediation server 1502a may be connected to the web server 1502b or the database server 1502c via the Internet. The mediation server 1502a may call data from the web server 1502b or the database server 1502c, and the mediation server 1502a may use the called data based on criteria (search keywords) input by the seller or the buyer. You can search for proposals.

 The web server 1502b collects data from buyer personal computers 1504, 1506, 1508 and seller personal computers 1510, 1512, 1514 via the Internet 1500, and transmits the data to these personal computers. It can serve as a front-end server.

 The data as described above may be stored in the database server 1502c.

 1 is a flow diagram of a method for conducting an online reverse auction in accordance with one embodiment of the present invention. 2A, 2B, and 2C are more detailed flowcharts of FIG. 1 to make the present invention easier to understand. However, Figures 1, 2A, 2B, and 2C help to understand the present invention but do not limit the scope of the present invention.

 In step 100 of FIG. 1, after the buyer and the seller connect to the mediation server through the Internet, the first buyer and the seller register with the mediation server, and in the case of the previously registered buyer and seller, the user authentication is performed. Going through.

 In step 102, the buyer may submit a joint purchase offer to the mediation server, which suggests joint purchases to other buyers, to recruit the joint purchase participants or participate in the joint purchase offer of the other buyers. The basic form of the joint purchase offer is provided by an intermediary server. It is easy to imagine that buyers participating in the joint purchase offer will be buyers considering the same kind of goods.

 In step 104, the joint purchase recruiter submits a purchase proposal which fills in the basic or details of the joint purchase desired product to the intermediary server when the conditions for proceeding the joint purchase are satisfied. The basic form of the purchase proposal is provided by the mediation server. In step 104, the seller is a product that is not yet well known to buyers, or a rare product, or if the buyer has not yet submitted a purchase proposal but owns or provides a product that will be in demand, Product proposal) and sales information on the product may be submitted in addition to the product information (product proposal). The basic form of the product information (commodity proposal) and the sales information is provided by the intermediary server.

 In step 106, the seller searches for the purchase proposal of the buyer and if there is a purchase proposal for the product he wants to sell, the seller submits a sales bid for the product in the purchase proposal, If there is a product information (product proposal) for the product that you want to sell, submit the sales information about the product to the product information. The basic form of the sales bid is provided by the mediation server. The purchase proposal and product information (commodity proposal) may be searched simultaneously or may be individually searched according to a buyer or seller's selection.

 In step 108, one or more unspecified buyers bid on the sales bid submitted by each seller in the other buyer's proposal or bid on the sales information submitted by each seller in the seller's proposed product information (product proposal). can do. Here, the sales bid in the proposal may be conducted as an independent auction in addition to the bid submitted to the proposal (as an independent auction in which other buyers may participate in addition to the buyer who submitted the proposal). Similarly, the sales information in the product information sheet (Proposal Proposal) proceeds as an auction where buyers can participate.

 In step 110, the buyer and the seller can observe the details of the purchase proposal or product information (commodity proposal) and observe the sales bid and sales information for each of the proposals described above, the sales bid and sales information You can also observe buyers' bids for books.

 In step 112, the buyer who submits a purchase proposal may accept or reject one or more bids, or make further proposals. However, a buyer who submits a purchase proposal cannot withdraw the proposal even if the buyer refuses the bid. Even if the buyer accepts the bid, the purchase proposal is still valid. This is because the sales bid submitted by the seller in the purchase proposal is being processed as another independent auction. A purchase proposal submitted by a buyer is valid until the end of the auction of the sales bids bidding on the purchase proposal.

 In step 114, the seller may accept, reject, or make another proposal offered by the buyer of the purchase proposal that he bid. In addition, the seller may accept or reject the bids of the buyers who bid on the sales bid or sales information submitted by the seller, or may make an additional proposal.

 In step 116, a buyer who bids on the seller's sales bid or sales information can accept or reject the seller's additional offer, or make another offer.

 In step 118, the mediation server accepts the confirmation of acceptance for each bid upon reaching an agreement between the trading parties.

 In step 120, when the buyer deposits a successful bid to the mediation server, the mediation server takes care of the successful bid until the transaction is safely made, and the buyer delivers the total amount of the successful bid or the limited amount of the mediation fee to the seller when the buyer wishes to purchase. In the event of a buyer's request for a refund, the full amount of the winnings or the fee shall be returned to the buyer. As a result, the transaction at the intermediary server of the reverse auction system according to the present invention is terminated.

A seller with a filing order includes a sale bid 308, which includes the goods described above, with the additional terms presented by each seller, and each buyer 2, buyer 3,... In this case, it can be said that the buyer n bids 310 at the seller's bid 308 that satisfies his purchase condition. Similarly, in FIG. 3C, each seller having a product similar to the product information (product proposal) 312 in the product information (product proposal) 312 submitted by the seller 1 to the intermediary server includes the product. In addition, the sales information sheet 314 including the conditions to be additionally presented is submitted, and each buyer 1, buyer 2, ..., buyer n satisfies their purchase conditions in the submitted sales information 314.

 If the user visits the mediation server for the first time and wants to use the service, the user ID and password can be registered through the user registration process. If the user is a registered user, the user can log in using the registered user ID and password.

The main screen of the mediation server shown in FIG. 4 includes My mazv (400), suggest (402), suggestion book (404), our space (406), help (without reference sign), and product search. A search condition 408, a search keyword input field 410, and a menu such as primary classification and secondary classification of each product are shown.

 Among the menus shown in FIG. 4, My mazv 400 is one of the services provided by the mediation server. If the user selects the menu using a user interface tool such as a mouse, the purchaser is responsible for the matters related to his purchase. All of them move to the virtual space, which is integrated with each other. Similarly, the seller moves to the virtual space of all the sales related matters.

 Proposal (402) is a menu that is used when a buyer submits a proposal for a product to be purchased as a service provided to the buyer.

 Proposal Finder (404) menu is a menu used to find a purchase proposal or product information (commodity proposal) for a product to be sold as a service provided to the seller.

 Our space 406 menu is a service provided to all users who use the intermediary server. Through this service, the user can be provided with a service that can spend leisure time in addition to sales and purchase. Of course, such a service is not related to purchase or sale because it is a service provided to further elevate the quality of the e-commerce service which is the object of the present invention. This will be described in detail later with reference to FIG. 10.

 The search condition 408 is a user selects a condition for searching for a product, and the search keyword input field 410 is a space for inputting a search keyword suitable for the search condition 408.

 The home appliance 412 and the MP3 414 are items corresponding to the primary classification and the secondary classification selected to describe the embodiment of the present invention.

You can also search directly by selecting.

 To illustrate one embodiment of the present invention in accordance with the process of the flowchart shown in FIG. 1, assume that the purchaser has selected the menu of our space 406 in FIG. The user interface can then be shown as in FIG.

 In FIG. 10, the homepage 1002 is a menu linked to the user's homepage, and the seller homepage 1004 is a menu associated with the homepage of the seller selling the product. Gather tool 1006 is a menu provided separately for purchasers to recruit a joint purchase or to participate in a joint purchase, the current location 1008 informs the user's location within the intermediary server. The tool recruitment search condition 1010 is a menu for selecting a condition for a user to search for a collective purchase article, and the search keyword input field 1012 is a space for inputting a search keyword corresponding to the search condition 1010.

 Tool recruiting category 1016 is provided by the mediation server according to the sales goods, as shown in the primary classification shown in FIG. Although the number and type of sorts are the same as those of the primary classification shown in FIG. 4, the classification 412 shown in FIG. 4 is a virtual space for selling and purchasing goods, and the classification 1018 shown in FIG. 10 indicates a joint purchase. The difference is that it is a virtual space for recruiting or participating. In other words, the same kind and number are classified in separate virtual spaces.

If the buyer has chosen to recruit 1014 to recruit a co-purchase, the user interface may be shown as in FIG. 11A. The diagram shown in FIG. 11A is provided by an intermediary server in a basic format in which a buyer fills in predetermined information for recruiting a joint purchase.

 For the sake of understanding, let's assume a buyer wants to buy a product called IFP-790 from iRiver's MP3 player and additionally prepaid accessory sets and shipping. Buying with a number of people through a joint purchase can buy cheaper, so the joint purchase offer is written as shown in Figure 11a.

 First, the home appliance 1102 is selected in the primary classification and MP3 1104 is selected in the secondary classification. The choices available in each category are provided by the intermediary server and do not need to be selected if they are not in the category. Tertiary classification 1106 and quaternary classification 1108 may be used where more details are needed. For example, as described above, when the home appliance is selected as the primary classification and the MP3 is selected as the secondary classification, the manufacturer name of the MP3 may be selected as the third classification, and the model name of the manufacturer's product may be selected as the fourth classification. In the summary product information 1110, the manufacturer and model name, and additionally, the product to be purchased are entered, iriver in the brand name 1112, and IFP-790 (256) in the product name 1114.

As a result of searching through the proposal search menu 404 of FIG. 4, if a buyer or other sellers do not submit a proposal for a product they have obtained, the seller may inform the buyer of the product information (product) Proposal). If the proposal 402 of FIG. 4 is selected to prepare a product information sheet (product proposal), the user interface may be shown as shown in FIG.

 7 shows a form of a product information document (product proposal) provided by an intermediary server. This form is only part of one embodiment of the invention and does not limit the scope of the invention. Form items of the product information sheet (commodity proposal) include the primary classification (702), the secondary classification (704), the tertiary classification (706), the fourth classification (708), the summarized product information (710), and the brand name (712). ), Brand name (714), product status (716), country of origin (718), purchase price (720), A / S availability (722), search keyword (723), and detailed information input (724). . If the seller "niddong" properly fill out the form item of the product information form, select Submit (not shown) and submit the created product information to the intermediary server. The purchase price 720 is the item to be filled in the case of used goods. In the detailed information input 724 column, the seller can inform the buyers of the details of the product, the function, etc. of the product he received through the HTML editor or direct input. 5B is a screen shown in a user interface when the seller "niddong" submits the created product information (commodity proposal) to the mediation server, and may be referred to as a result obtained by the other buyer or seller through a search. .

 The product information sheet (commodity proposal) is merely for informing the buyers and sellers of the products owned by them and cannot be sold. That is, buyers cannot bid. Therefore, in order for a seller who submits the product information (product proposal) to sell his or her goods, the seller must remind his sales information in the same way that other sellers submit the sales information in the product information (product proposal) submitted by him. It should be submitted in the product information sheet.

 When the seller "niddong" submits the product information (product proposal), the sales information form provided by the intermediary server is shown in the user interface as shown in FIG. 8A. The form item includes summary sales information (802), brand name (804), brand name (806), product status (808), country of origin (810), purchase price (812), auction period (814), sales quantity (816). , Immediate purchase price (820), maximum bid quantity (822), payment method (824), sales region (826), shipping costs (828), after-sales service (830), search keywords (831), details and Other terms and conditions (832). If the seller "niddong" properly filled out the form item of the sales information, select Submit (not shown) and submit the created sales information to the mediation server.

Will submit. Other sellers prepare and submit sales information in the same way as the seller.

 If a seller has searched for a proposal and a product proposal (product proposal) already exists for the same product, he or she can still submit a product proposal (product proposal), but he will not do so if he is an experienced seller. This is because buyers are more likely to attract more buyers in one place than the same product is scattered in various places, and even if the same product is sold, the price, style, and additional service offered by the seller are different. In Esau, it is obvious to select a product information sheet (product proposal) that has a wide range of choices, that is, a lot of sellers participate. And since this will have a direct impact on the seller's product sales volume, if a product information sheet for a product already exists, submitting the sales information sheet to the product information sheet is not a loss, but rather a gain in sales. This can be seen as offline sales, for example, when buyers are buying clothes that are concentrated in dozens of clothing stores rather than in a single clothing store. It would be easy to see if buyers are gathering in a lot of clothing stores such as Dongdaemun Market rather than neighborhood clothing stores.

 The sales information submitted by the sellers may be posted as shown in FIG. 8B in the product information sheet (product proposal).

 The user " sonsory " can notify the co-purchase currently in progress through a message or mail service provided by the intermediary server through their ID 1424 of the co-purchase 1422 shown in FIG. 14C. The co-purchase information and the IDs of other purchasers who participated in the co-purchase are recorded together in the diary of the co-purchase recruiter who performed the co-purchase, as well as the participating buyers, and the user is recorded in the diary 1408. Through the user's ID, the user can visit the mini homepage of other users who participated in the same joint purchase, so that they can socialize among the users who participated in the joint purchase, and notify the information about another joint purchase as described above. It will be easier to recruit joint purchase participants. The more co-purchase participants, the more sellers can sell and the more sellers can expect.

 It is also possible to more easily recruit co-purchasers through a service (not shown) that can recommend or search for buyers with similar consumption tendencies.

 Although the present invention has been described in connection with the foregoing embodiments, it will be apparent to those skilled in the art that many alternative embodiments, modifications and variations are apparent. Accordingly, the above-described embodiments of the present invention are illustrative and are not intended to limit the present invention. Many changes may be made without departing from the spirit and scope of the invention.

As described above, according to the present invention, a single purchaser secures a purchase quantity for a specific product for an unspecified number of buyers, and performs a reverse auction on the product to purchase a product from the seller, so that the buyer can buy a large amount of collective purchase. Through the purchasing power of the reverse auction method and offers the opportunity to purchase the desired product at a low price, the seller has the effect of providing the opportunity to sell a large amount of products at a desired price at a time. In addition, when another buyer other than the buyer who participated in the joint purchase bids on the seller's bid, the buyer can purchase the product at the same low price as the buyer who participated in the joint purchase even if one buyer buys the product, and the seller additionally purchases the product. You will be able to sell more.

In addition, since the present invention can expect bids of other buyers other than the proposers of the reverse auction even if the sellers participating in the reverse auction do not receive a bid as described above, the sellers participating in the reverse auction may feel rejected. It can relieve anxiety, so it is effective to recruit sellers naturally.

In addition, the present invention by allowing the seller to inform the buyer through the product information (commodity proposal) as a newly obtained product, as described above, the paradox of the conventional reverse auction method that the product cannot be sold until the buyer proposes Solved the problem. In addition, by allowing the sellers to sell the corresponding product only by submitting sales information about the corresponding product in the product information sheet, the free competition of the sellers can be induced so that the buyer can purchase the corresponding product at a reasonable price.

In addition, in the present invention, since the seller submits a sales bid or a sales information about a product to be sold in a corresponding purchase proposal or a product information sheet (commodity proposal), similar sales products are naturally arranged so that the buyer can You can easily avoid irrelevant products, that is, spammy products. Therefore, it is possible to save the time for the buyer to shop the product and to free e-commerce from spam products. The spam product is a product that is irrelevant to MP3 when searching for a product by setting a search keyword of a product that is sold to a product (eg, MP3) that is highly demanded by buyers, but is searched along with the MP3 products and is not desired by the buyer. Refers to a product that is exposed to However, in the present invention, before the mediation server finds a product corresponding to the search keyword input by the user, sellers submit similar sales items or sales information for the product they want to sell in the proposal. Since it is naturally arranged, it is difficult for spam media to exist in the mediation server according to the present invention.

 In addition, in the present invention, the purchase proposal submitted by the buyer or the product information (product proposal) submitted by the seller generates a category within the first, second, third, and fourth classifications, and owns the corresponding product in the category. Since sellers are competing by submitting sales bids or sales information, they are free from the dominance of the intermediary server, and the market can be freely formed only within the minimum framework provided by the intermediary server.

In other words, the conventional auction method and the reverse auction method were referred to as seller-centered or buyer-centered auctions, respectively, but this was a buyer-centered auction method under the control of the broker server or the broker-centered server. In other words, the conventional auction method and the reverse auction method, because the auction proceeded only under the category provided by the mediation server, the seller and the buyer has been buying or selling under perfect control of the mediation server. However, in the electronic commerce method according to the present invention, since the proposal submitted by the buyer or seller generates each category to organize related sales bids and sales information, the intermediary server may provide only a minimum frame. Therefore, sellers and buyers can freely create categories of products they want to freely create their own market. That is, the electronic commerce method according to the present invention may be referred to as an electronic commerce method centered on both the seller, the buyer, and the mediation server.

In addition, according to the present invention, since the sale of goods is made beyond the space, a number of sellers and buyers distributed in various places can easily trade on the Internet. Buyers can easily purchase the products they want through the Internet, and sellers who want to sell certain products can sell them without having physical stores, resulting in reduced product flow margins, thereby reducing unnecessary spending on both sides. do.

In addition, according to the present invention, by providing an opportunity and fun to know a variety of people through the mini-homepage service provided by the intermediary server, even if you do not know each other's face to be able to promote the friendship between users, You may be invited to participate in a joint purchase offer that is either recruiting or participating. Therefore, this has a direct influence on the sales of the sellers, and not only promotes the enjoyment and friendship of the users, but also improves the sales of the sellers.
