Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If non-customizable circuitry is used in solar energy systems, then manufacturing complexity is reduced, but adaptability to different voltage and amperage requirements deteriorates

Engineering Contradiction:
Improvemanufacturing complexityVSAvoidadaptability to voltage and amperage requirements
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The circuit board is divided into multiple slots that can accommodate different overcurrent protection elements (fuses, breakers, MAXI fuses) with varying amperage ratings. This segmentation allows the system to be manufactured with a standardized base configuration while enabling customization through slot-specific component selection, thus resolving the contradiction between manufacturing simplicity and adaptability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The circuit board is designed with universal slots that can accept multiple types of overcurrent protection elements (fuses, breakers, MAXI fuses) interchangeably. This multi-functionality allows a single circuit board design to serve multiple voltage and amperage configurations, maintaining ease of manufacture while achieving versatility across different system requirements.

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

2Adaptability or versatility

If customizable overcurrent protection elements are integrated into the circuit board, then adaptability to user requirements is improved, but device complexity increases

Engineering Contradiction:
Improvecustomizability of overcurrent protectionVSAvoidcircuit board complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The circuit board features distinct, dedicated slots for different types of overcurrent protection elements (first slot for fuse, second slot for breaker, third slot for MAXI fuse). This segmentation organizes the complexity into manageable, standardized sections, making the customization process simpler despite the increased number of components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each slot on the circuit board is designed with specific local characteristics optimized for its intended overcurrent protection element type. The first slot is configured for fuses, the second for breakers, and the third for MAXI fuses, with each location having tailored electrical and mechanical properties. This local quality approach manages overall device complexity by assigning specific functions to specific locations.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If a user interface with AI-driven calculations is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveuser-friendliness of configurationVSAvoidsoftware complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The user interface automatically performs AI-driven calculations to determine the appropriate overcurrent protection element ratings based on user inputs about system requirements. The system serves itself by autonomously computing the correct fuse, breaker, or MAXI fuse ratings without requiring users to manually calculate or understand complex electrical specifications, thus improving ease of operation while managing software complexity through automation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The user interface provides real-time feedback to users as they input system parameters, automatically calculating and displaying the recommended overcurrent protection element ratings. This feedback mechanism guides users through the configuration process, making the system easier to operate by providing immediate, actionable information while managing software complexity through structured calculation algorithms.

Inventive Principle:
