Solution Overview

Problem

Existing server rack locks rely on mechanical keys and combination codes, which are prone to issues such as key breakage, ease of copying, and lack of user traceability, while electronic locks require cumbersome wiring and infrastructure for power and control.

Innovation Solution

A programmable electronic key system that uses wireless communication and rechargeable power sources to operate passive security devices, eliminating the need for internal power in the devices and enabling secure, traceable access management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard mechanical keys and combination codes are used for server rack protection, then the system is simple to implement, but it suffers from key breakage, ease of copying, lack of user traceability, and difficulty in managing access to multiple locks

Engineering Contradiction:
Improvesecurity reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical key systems with electronic locks that use electronic authentication mechanisms. The electronic lock contains an authentication module that verifies user credentials electronically, eliminating physical keys and combination codes. This substitution provides user traceability through electronic records while maintaining simplicity through integrated power management that eliminates extensive wiring requirements.

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

2Reliability

If electronic locks with wiring and infrastructure are installed to provide power and control, then user traceability and access management improve, but the device complexity and installation cost increase significantly

Engineering Contradiction:
Improveaccess control reliabilityVSAvoidwiring infrastructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The electronic lock incorporates an internal power management module with rechargeable battery and wireless charging capability. The lock can autonomously recharge itself by wirelessly receiving power from a charging base, eliminating the need for external power wiring and infrastructure. This self-service approach maintains electronic authentication and user traceability while dramatically reducing installation complexity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent introduces a wireless charging base as an intermediary between the power source and the electronic lock. The charging base wirelessly transmits power to the lock when placed on it, serving as a mediator that eliminates the need for direct electrical wiring to the lock while still providing reliable power supply for authentication operations.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If extensive network of data cables and hubs are installed to track user interactions, then user traceability improves, but the device complexity and installation overhead increase

Engineering Contradiction:
Improveuser interaction traceabilityVSAvoidnetwork infrastructure complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines the authentication module and the data tracking functionality into a single integrated electronic lock unit. The authentication module simultaneously performs user verification and records interaction data locally, eliminating the need for separate data cables and hubs. This merging maintains complete user traceability while reducing network infrastructure requirements to minimal wireless communication capabilities.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Embodiments of the present invention are directed to systems and methods for preventing unauthorized access to server racks. In one example, a system includes an electronic key and an electronic lock configured to be attached to the server rack. The electronic lock is configured to communicate with the electronic key for determining whether the electronic key is authorized to unlock or lock the lock. The electronic lock includes a handle configured to be disengaged from the electronic lock when the electronic key is authorized, and the handle is configured to be actuated to unlock the lock for accessing the server rack when the handle is disengaged from the electronic lock. The electronic lock is configured to re-lock only when the handle is engaged with the electronic lock.
