Smart Shoe Biometric Authentication and Theft Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shoes, especially high-value ones, are at risk of theft and loss due to improper storage and identification challenges in public areas like gyms and beauty salons, leading to increased losses.
Innovation Solution
A smart shoe equipped with a foot sole print recognition sensor, processor, storage, and alarm system that matches user foot sole print information to prevent unauthorized use, along with a retractable heel and pedometer for health monitoring, and communication modules for data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If shoes are stored in open areas for easy access, then ease of operation is improved, but reliability deteriorates due to theft and loss risks
Solution Approach 1:
The patent applies preliminary action by pre-registering the user's foot sole print information in the storage device before the shoe is stolen or lost. When the shoe is picked up, the system automatically compares the current print with the registered information and triggers an alarm if they don't match, preventing theft before it can be completed successfully.
Solution Approach 2:
The system applies self-service by automatically performing the authentication process without requiring manual intervention. The foot sole print recognition sensor automatically captures the print, the processor compares it with stored information, and the alarm activates if unauthorized use is detected, making the security system autonomous and always active.
2Reliability
If foot sole print recognition sensor is added to authenticate users, then reliability is improved, but device complexity worsens
Solution Approach 1:
The patent applies universality by making the shoe serve multiple functions: it provides the basic footwear function while also incorporating security authentication, health monitoring through pedometer, and data communication capabilities. This multi-functionality justifies the added complexity by delivering comprehensive value beyond simple shoe protection.
Solution Approach 2:
The system merges multiple functional components into a single integrated shoe unit. The foot sole print recognition sensor, processor, storage device, alarm device, pedometer, and communication module are all combined within the shoe structure, creating a unified smart shoe system that performs security, health, and communication functions simultaneously.
3Reliability
If alarm device and communication module are added to transmit alerts, then reliability is improved, but loss of energy worsens
Solution Approach 1:
The system applies periodic action by activating the alarm device and communication module only when needed - specifically when the foot sole print authentication fails. The sensor continuously monitors but the high-energy alarm and transmission functions operate periodically rather than continuously, significantly reducing overall energy consumption while maintaining reliable theft prevention capability.
