Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dedicated specialized apparatus are used for each photography technique, then reliability and precision of each technique is improved, but device complexity and the number of required components increases

Engineering Contradiction:
Improvereliability of photography techniqueVSAvoidnumber of specialized apparatus
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The motor assembly is designed with a universal coupling member that can interface with multiple different driven components (camera, lens, filter holder) through a standardized coupling interface. This allows a single motor assembly to perform multiple photography functions (panning, tilting, focus control, iris control) that traditionally required separate dedicated apparatus, thereby reducing overall system complexity while maintaining reliable control precision for each function

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

2Adaptability or versatility

If a versatile multi-functional system is created, then adaptability and versatility are improved, but device complexity increases

Engineering Contradiction:
Improveversatility of motor systemVSAvoidcomplexity of motor assembly
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The motor assembly is segmented into distinct functional modules: a motor unit, a coupling member with standardized interface, and interchangeable driven components. This modular segmentation allows the system to achieve versatility through combination of simple, well-defined modules rather than a single complex integrated system, making the overall assembly more manageable and easier to adapt to different configurations

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling member incorporates a universal interface design that can accommodate multiple types of driven components (camera bodies, lenses, filter holders) through standardized mounting features. This universality enables a single motor assembly to control diverse photographic equipment without requiring complex specialized interfaces for each component type, thereby achieving versatility while controlling complexity

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

3Manufacturing precision

If traditional rigid coupling is used between motor and driven component, then manufacturing precision is improved, but adaptability and ease of configuration deteriorates

Engineering Contradiction:
Improveprecision of motor connectionVSAvoidflexibility of system configuration
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The coupling member incorporates adjustable and reconfigurable features that allow the connection between motor and driven component to be dynamically adapted. The coupling interface can be configured in different positions and orientations to accommodate various driven components while maintaining precise mechanical engagement, thereby achieving both manufacturing precision and configurational flexibility that rigid fixed couplings cannot provide

Inventive Principle:
Principle #15Dynamics
