Controlled-Access Vending Delivery With Remote Purchase Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vending machines do not allow for remote purchase of items, do not distribute items based on recipient identity, and lack rules for dispensing items, leading to unrestricted access and potential abuse.
Innovation Solution
A delivery system that identifies recipients via identification devices, applies personalized rules for item dispensing, and bills purchasers based on recipient type, with features like item alerts and refunds for undelivered items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional vending machines are used for item distribution, then item dispensing is simple and quick, but access is unrestricted and abuse potential is high
Solution Approach 1:
The patent introduces a rule-based vending machine system that acts as an intermediary between the purchaser and the items. The system includes a rule database, processor, and communication interface that mediate the dispensing process by evaluating purchaser identity, item type, quantity, and facility rules before allowing dispensing, thereby controlling access without requiring complex manual oversight
Solution Approach 2:
The system segments the vending machine functionality into distinct modules: identification device for purchaser verification, rule database for storing dispensing criteria, processor for evaluating rules, and dispensing mechanism. This segmentation allows each component to perform its specific function independently, managing complexity through modular design while maintaining reliable access control
2Ease of operation
If remote purchase capability is added to vending machines, then purchaser convenience is improved, but system complexity increases
Solution Approach 1:
The patent replaces the traditional mechanical interaction at vending machines (inserting cash, pressing buttons) with electronic/remote purchasing methods. The system accepts purchase requests through communication interfaces that can receive electronic signals from remote devices, eliminating the need for physical presence at the machine while maintaining the dispensing function through automated rule evaluation
Solution Approach 2:
The vending machine system is designed with universal communication capabilities that can interface with multiple types of purchasing devices (mobile devices, computers, kiosks). The rule-based evaluation system is also universal, applicable to different purchaser types, item categories, and facility rules, allowing the same system to handle diverse purchasing scenarios without requiring separate specialized systems
3Reliability
If rule-based dispensing is implemented, then item distribution control is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by pre-storing comprehensive dispensing rules in the rule database before any purchase occurs. These rules cover purchaser eligibility, item availability, quantity limits, and facility-specific restrictions. When a purchase request is made, the system only needs to evaluate against pre-established rules rather than making decisions in real-time, significantly reducing processing time while maintaining rigorous control
Solution Approach 2:
The system implements feedback mechanisms where the processor continuously monitors dispensing transactions and updates the rule evaluation based on current stock levels, purchaser history, and facility conditions. This feedback loop allows the system to adapt to changing circumstances while maintaining consistent rule-based control, and the automated nature of this feedback processing minimizes time loss compared to manual rule checking

AI summary
A delivery system applies rules for authorizing transactions to a recipient that are individualized for each recipient. These rules may limit the number of items available for the purchaser to purchase for a recipient, the types of items available for purchase for a recipient, and the price of the items for the recipient. The system automates the delivery of the item to the recipient via a kiosk, such as a vending machine. An identification device of the vending machine identifies the recipient. The vending machine dispenses the items to the identified recipient.
