Solution Overview

Problem

Self-storage facilities face challenges with conventional over-lock systems, including high operational costs, manual intervention requirements, delayed access for customers, and security issues with vacant units, due to the need for on-site attendance and frequent lock changes.

Innovation Solution

A distributed over-lock system that uses a combination over-lock with a unique identifier and unlock code, managed through a lock management system and property management system via API, allowing customers to access their units electronically without human intervention, and automatically securing vacant units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If conventional electronic over-locks are used, then automated and remote locking/unlocking functions are provided, but significant capital improvements are required and power consumption costs increase

Engineering Contradiction:
Improveautomated locking/unlockingVSAvoidpower consumption
Core Design Contradiction:
Extent of automationVSUse of energy by stationary object

Solution Approach 1:

The patent replaces electronic locking mechanisms with a mechanical combination lock system. The over-lock uses a combination dial and tumblers mechanism that can be operated manually by customers without requiring electricity, thereby eliminating power consumption costs while maintaining automated access capabilities through the combination code system.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent extracts the electronic power requirement from the over-lock system by using a purely mechanical combination lock. The locking and unlocking functions are achieved through mechanical manipulation of the combination dial and tumblers, removing the need for continuous power supply while preserving the automated remote access functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If standard combination over-locks are used, then cost is reduced, but delinquent customers can recognize unlock codes and security is compromised

Engineering Contradiction:
ImprovecostVSAvoidsecurity
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent implements dynamic code changes where the combination code is not fixed but can be changed by facility staff whenever needed. This allows the system to adapt to security threats by changing codes dynamically, preventing customers from recognizing and memorizing the same code repeatedly, while maintaining the low cost of mechanical combination locks.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of the combination code from static to dynamic. The code can be modified by facility personnel at any time, allowing the system to respond to security compromises by changing the code parameter without replacing the entire lock mechanism, thus maintaining both low cost and high security.

Inventive Principle:
Principle #35Parameter changes

3Ease of manufacture

If manual over-lock removal is used, then simple mechanical locks are employed, but customer access is delayed until office hours

Engineering Contradiction:
ImprovesimplicityVSAvoidaccess delay
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent enables customers to service their own lock by providing them with the combination code through electronic communication. Customers can independently unlock their own over-locks without requiring facility staff presence, allowing immediate access at any time while using simple mechanical lock technology.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces an electronic communication system as an intermediary between the facility and customers. This intermediary delivers the combination code to customers electronically, enabling them to access their locks independently at any time, thereby eliminating access delays while keeping the lock mechanism itself simple and mechanical.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If on-site personnel attendance is required for over-lock management, then direct control is maintained, but operational costs and time consumption increase

Engineering Contradiction:
ImprovecontrolVSAvoidoperational efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent implements a self-service system where customers manage their own over-lock access by receiving combination codes electronically. This eliminates the need for on-site personnel to manually manage each lock, maintaining reliable control through the code delivery system while dramatically improving operational efficiency by removing manual intervention requirements.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical manual control system with an electronic code delivery and communication system. This substitution maintains reliable control over lock access while eliminating the need for on-site personnel attendance, thereby improving productivity by automating the control mechanism.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The disclosure generally relates to a system and method for managing distributed encrypted combination over-locks from a remote location. In an exemplary embodiment, the invention is a distributed management system for self-storage facilities that allow for vacant units to be secured with over-locks without requiring unlock codes, and which allow the over-locks to be removed by customers without human or manual intervention from the self-storage facility, where an API is used to facilitate communications between a lock management system and a property management system.
