Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wireless communication (Wi-Fi) is used instead of wires for environment control system components, then deployment cost and disruption are reduced, but compatibility with legacy wired components becomes problematic

Engineering Contradiction:
Improvedeployment costVSAvoidcompatibility with legacy components
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent introduces a gateway as an intermediary device that bridges wired and wireless communication protocols. The gateway converts signals between wired and wireless formats, enabling legacy wired components to communicate with modern wireless components without requiring direct compatibility between them. This resolves the contradiction by allowing cost-effective wireless deployment while maintaining compatibility with existing wired infrastructure through the gateway mediator.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If physical wiring is deployed for environment control system components, then reliable communication is achieved, but deployment disruption and cost increase

Engineering Contradiction:
