Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mobile phone case with camera positioning area and snap-fits is used to connect photographic lenses and filters, then the convenience of adapting various photographic lenses and filters is improved, but the versatility for broader shooting needs remains limited

Engineering Contradiction:
Improveconvenience of adapting photographic lenses and filtersVSAvoidversatility for broader shooting needs
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The expansion frame provides multiple installation interfaces that can accommodate various types of accessories beyond just photographic lenses and filters, including microphones, lights, and other shooting accessories. This multi-functional design allows a single device to serve multiple photography and recording needs, thereby improving versatility while maintaining ease of operation through standardized interfaces.

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

2Adaptability or versatility

If multiple installation interfaces are added to the expansion frame to support various accessories, then the versatility for diverse shooting needs is improved, but the device complexity increases

Engineering Contradiction:
Improveversatility for diverse shooting needsVSAvoidcomplexity of expansion frame structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The expansion frame is divided into multiple independent installation interfaces, each capable of accommodating different types of accessories. This segmentation allows the system to support diverse accessories without requiring a completely different design for each accessory type, thereby improving versatility while managing complexity through modular, standardized interface design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple installation interfaces with standardized designs enable the expansion frame to support various accessories (lenses, filters, microphones, lights) through a common mounting mechanism. This universal approach improves versatility without proportionally increasing complexity, as the same basic interface structure is reused across multiple locations and accessory types.

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

3Adaptability or versatility

If electrical interfaces are added for power supply and communication with accessories, then the functionality and versatility are improved, but the device complexity and potential harmful factors increase

Engineering Contradiction:
Improvefunctionality for power supply and communicationVSAvoidpotential electrical hazards and complexity
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The expansion frame serves as an intermediary device between the electronic device and various accessories, providing standardized electrical interfaces that safely manage power supply and communication signals. This intermediary role allows electrical connections to be made through a controlled interface that can protect against electrical hazards while enabling enhanced functionality for powered accessories.

Inventive Principle:
Principle #24Intermediary (Mediator)
