Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If microcontrollers with limited capabilities are used for control and monitoring, then cost is reduced, but configuration and maintenance complexity increases due to limited computing speed, RAM, and operating system capabilities

Engineering Contradiction:
ImprovecostVSAvoidconfiguration and maintenance complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

A web server is introduced as an intermediary between the microcontroller-based emergency lighting system and the user interface. The web server handles complex configuration tasks, data processing, and communication protocols, while the microcontroller focuses on core control functions. This mediator approach allows the use of low-cost microcontrollers while maintaining system configurability through standard web browsers without requiring specialized software installations.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system uses standard web browsers as a universal interface for configuration and monitoring, replacing manufacturer-specific proprietary software. This multi-functional approach allows any browser-capable device to interact with the system, eliminating the need for specialized hardware configurations and software installations, thereby reducing maintenance complexity while keeping microcontroller costs low.

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

2Ease of operation

If proprietary client software is used for configuration, then ease of operation improves, but adaptability decreases because access from another calculation unit requires reinstalling software

Engineering Contradiction:
Improveease of configurationVSAvoidremote maintenance capability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system replaces proprietary client software with a web-based interface accessible through standard browsers. This universal approach allows configuration and monitoring from any browser-capable device without requiring software installation or reinstallation, thereby improving both ease of operation and adaptability for remote maintenance scenarios.

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

Solution Approach 2:

The patent substitutes the mechanical/software installation process with a web-based access model. Instead of installing proprietary client software on specific hardware, the system uses network-based web protocols that can be accessed from any device with a browser, eliminating the need for physical software distribution and installation procedures.

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

3Adaptability or versatility

If specialized software is installed on a PC for system configuration, then functionality improves, but device complexity increases due to hardware configuration and operating system requirements

Engineering Contradiction:
Improveconfiguration functionalityVSAvoidhardware and software configuration
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the complex configuration functionality from the microcontroller and relocates it to a web server. This separation allows the microcontroller to remain simple and cost-effective while the web server handles sophisticated configuration tasks, data management, and communication protocols through standard web protocols accessible via any browser.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A web server acts as an intermediary layer between the simple microcontroller system and the user's PC/browser. This mediator handles all complex software requirements, operating system interactions, and hardware configurations, allowing the microcontroller to remain hardware-simple while providing full configuration functionality through the web interface.

Inventive Principle:
Principle #24Intermediary (Mediator)
