Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If solar arrays are fixedly attached to satellites prior to launch, then energy supply is guaranteed, but space restrictions within the launcher system increase and design flexibility is reduced

Engineering Contradiction:
Improveenergy supply guaranteeVSAvoidsatellite design flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The solar array system is divided into modular solar array units that can be independently configured and attached to the satellite after launch. Each unit can be separately deployed and positioned, allowing flexible adaptation to different satellite designs and power requirements without compromising the reliability of energy supply.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solar array configuration is made dynamic and adjustable after launch rather than being fixed beforehand. The modular units can be repositioned, reconfigured, or replaced in space to adapt to changing power needs or mission requirements, while still ensuring continuous energy supply to the satellite.

Inventive Principle:
Principle #15Dynamics

2Power

If solar array dimensions are increased to meet higher power needs, then power supply capability is improved, but available space within the launcher system is reduced

Engineering Contradiction:
Improvepower supply capabilityVSAvoidlauncher system space
Core Design Contradiction:
PowerVSVolume of moving object

Solution Approach 1:

The solar array is segmented into multiple modular units that can be independently launched and deployed. This allows the satellite to start with a compact configuration that fits within launcher constraints, then expand power capacity by adding or deploying additional modules in space as needed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular solar array units are designed to be compactly stowed within the launcher system during launch, nested in a space-efficient manner. After deployment in space, these same units can be expanded and configured to provide the required power output, effectively transforming from a compact launch configuration to an expanded operational configuration.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Volume of moving object

If complex stowing solutions are implemented to accommodate solar arrays, then space utilization within the launcher system is optimized, but device complexity and tailoring costs increase

Engineering Contradiction:
Improvelauncher system space utilizationVSAvoidstowing solution complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

By segmenting the solar array into standardized modular units, the complexity of designing custom stowing solutions for each satellite is reduced. The modular design allows for通用的 launch integration approaches that can accommodate different power requirements without requiring complex tailoring for each mission.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The modular solar array units are designed with universal interfaces and standardized configurations that can be adapted to different satellite types and launcher systems. This universality eliminates the need for complex, mission-specific tailoring processes while maintaining efficient space utilization within the launcher.

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

4Manufacturing precision

If tailoring processes are performed prior to launch, then space constraints are addressed, but adaptability to changing power needs after launch is lost

Engineering Contradiction:
Improvepre-launch configuration precisionVSAvoidpost-launch power adjustment capability
Core Design Contradiction:
Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The modular solar array units are prepared and qualified beforehand for launch, ensuring they meet all technical requirements. However, their final configuration and assembly are deferred until after launch, allowing the system to maintain manufacturing precision during production while gaining the flexibility to adapt configurations in space based on actual mission needs.

Inventive Principle:
Principle #10Preliminary action
