Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current property securing entry key locks lack the ability to monitor and record the time of lock opening and closing by authorized users, and there is no system to securely transfer and manage access credentials for remote property entry.

Innovation Solution

A compact locking system with electronic circuitry and components for secure key storage, enabling remote installation of access credentials, monitoring entry and exit times, and using multi-factor authentication for controlled access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional lock system is used to store property entry keys, then the key storage function is provided, but the ability to monitor and record entry/exit times and user identification is lost

Engineering Contradiction:

Improveaccess management securityVSAvoidlocking system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions into a single locking system device: key storage compartment, electronic circuitry for time monitoring, user identification capability, and access control all merged into one integrated system. This resolves the contradiction by providing enhanced reliability through function integration while managing complexity through unified design rather than separate systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The locking system is designed to perform multiple functions: securing the key, monitoring entry/exit times, identifying users, and providing access control all through one device. This multi-functionality approach improves reliability by ensuring all access management needs are met by a single system while the complexity is justified by the comprehensive functionality provided.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If access credentials are remotely installed for multiple users, then the ease of access management is improved, but the security risk of unauthorized access increases

Engineering Contradiction:

Improveaccess credential managementVSAvoidaccess authorization security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system incorporates time monitoring and logging capabilities that provide feedback on who accessed the property and when. This feedback mechanism allows the key holder to monitor authorized user activities, maintaining security while enabling easy remote credential management. The feedback loop ensures accountability for each access event.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The locking system acts as an intermediary between the key holder and authorized users. It mediates access by controlling when and how authorized users can access the property through the stored key, while still maintaining the key holder's authority and oversight through monitoring capabilities. This intermediary role balances ease of access with security control.

Inventive Principle:

Principle #24Intermediary (Mediator)
