Solution Overview

Problem

Existing access control systems require costly updates and replacements, especially in wired installations, and are inefficient for retrofitting existing buildings, as they necessitate replacing all credentials and access control readers simultaneously.

Innovation Solution

The implementation of decentralized access control systems that utilize modular access control modules capable of operating at multiple carrier frequencies, allowing for credential migration and updates via wireless or wired communication, and featuring a base portion and an update portion that can be easily swapped or reprogrammed, enabling seamless transitions between different access credentials and frequencies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wired access control readers are installed in existing buildings, then access control functionality is provided, but installation costs and complexity increase due to rewiring requirements

Engineering Contradiction:

Improveaccess control functionalityVSAvoidinstallation cost

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces wired mechanical connections with wireless communication technology. Access control readers communicate with credentials and centralized control stations via wireless signals (RF, infrared, Bluetooth), eliminating the need for physical wiring through buildings. This substitution maintains reliable access control functionality while dramatically reducing installation complexity and cost in existing structures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If access control readers are updated to newer models, then system functionality is improved, but all credentials must be replaced simultaneously increasing cost and complexity

Engineering Contradiction:

Improvesystem functionalityVSAvoidupdate process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the access control system into independent modular components: readers, credentials, and control stations can be updated independently. Each component maintains compatibility through standardized communication protocols, allowing incremental updates rather than requiring simultaneous replacement of entire systems. This modular architecture enables phased implementation and reduces update complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements universal communication protocols and interfaces that allow different generations of readers and credentials to interoperate. Newer readers can read both old and new credential formats, and credentials can work with multiple reader types. This universality enables smooth transitions during system updates without requiring complete credential replacement.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If centralized control stations are wired to access points, then access control is provided, but retrofitting existing buildings becomes costly

Engineering Contradiction:

Improveaccess controlVSAvoidretrofitting ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces physical wiring connections between centralized control stations and access points with wireless communication infrastructure. Control stations communicate with distributed readers via wireless networks (WiFi, cellular, radio frequencies), eliminating the need to drill holes, run cables through walls, or modify building infrastructure. This enables easy retrofitting of existing buildings while maintaining reliable centralized control functionality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
