Self-Service Key Duplication Kiosk Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a long-felt need for a fully automatic key duplication system that allows consumers to easily duplicate keys without the assistance of a trained human operator, similar to vending machines or automated teller machines.
Innovation Solution
A self-service key duplication kiosk that includes a customer interface for payment, a key-receiving entry for key analysis, a key blank magazine, and a key duplicating system that replicates the tooth pattern of the inserted key onto a key blank, allowing customers to easily and automatically duplicate their keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fully automatic key duplication system is implemented, then the ease of operation and productivity are improved, but the device complexity increases
Solution Approach 1:
The key duplication system is divided into distinct functional modules: key insertion receptacle, optical scanning subsystem, key type identification module, key blank selection mechanism, cutting mechanism, and dispensing system. Each module performs a specific function independently, allowing the complex overall system to be managed through modular components that simplify operation while maintaining automation.
Solution Approach 2:
The system is designed as a self-service kiosk where customers independently insert their keys, receive automated identification and duplication, and collect their duplicate keys without human assistance. The optical scanning system automatically reads key features, the control system autonomously selects appropriate key blanks, and the mechanism self-executes the duplication process, eliminating the need for trained operators.
2Productivity
If automated key duplication is implemented, then productivity increases, but the manufacturing precision requirements become more stringent
Solution Approach 1:
The system replaces manual mechanical key duplication with an automated optical-mechanical system. Optical sensors scan and digitally record the precise tooth pattern geometry of the original key, then computer-controlled cutting mechanisms replicate the pattern on key blanks with high precision. This substitution of manual operations with automated optical measurement and computer-controlled cutting enables both high productivity and consistent manufacturing precision.

AI summary
A self-service, fully-automatic kiosk for duplicating keys includes a kiosk housing having a customer interface for receiving payment from a customer for the purchase of at least one duplicate of the customer's key. A key-receiving entry in the housing receives at least a portion of the customer's key to be duplicated, and a key analysis system within the housing analyzes the blade of a key inserted in the key-receiving entry to determine whether the inserted key matches one of a group of preselected key types and, if so, which preselected key type is matched. A key blank magazine within the housing stores key blanks for each of the preselected key types. A key blank extraction system extracts from the magazine a key blank for the preselected key type matched by the blade of the key inserted in the key-receiving entry. Then a key duplicating system within the kiosk replicates the tooth pattern of the blade of the key inserted in the key-receiving entry, on the blade of the extracted key blank.
