Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical analog modems and PSTN lines are used for elevator communication, then system compatibility with traditional elevators is maintained, but operational costs increase and system complexity increases

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

Solution Approach 1:

The patent creates software-based simulated modems that replicate the functionality of physical analog modems. These virtual modems emulate the behavior and communication protocols of traditional hardware modems, allowing legacy elevator systems to communicate over modern VoIP and internet infrastructure without requiring physical modem hardware at the datacenter.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical/physical modem hardware system with a software-based virtual modem system. Instead of using physical analog modems connected to PSTN lines, the invention uses software simulations running on servers that communicate through VoIP and internet protocols, eliminating the need for physical hardware while maintaining communication functionality.

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

2Adaptability or versatility

If physical analog modems are deployed at the datacenter, then communication with legacy elevator systems is enabled, but operational costs increase due to hardware maintenance and PSTN fees

Engineering Contradiction:

Solution Approach 1:

The patent implements a universal communication platform that can handle multiple communication protocols and methods. The software-based simulated modems can communicate over VoIP, internet protocols, and can interface with various elevator system types, making the system adaptable to different infrastructure requirements while maintaining a single hardware platform.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces software-based simulated modems as an intermediary layer between legacy elevator systems and modern communication infrastructure. This virtual modem layer translates and adapts communications between different protocols and systems, enabling flexible infrastructure choices without requiring changes to the elevator equipment itself.

Inventive Principle:
Principle #24Intermediary (Mediator)
