Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional release system is used, then satellite separation can be achieved, but the system becomes complex and costly

Engineering Contradiction:
Improveseparation reliabilityVSAvoidrelease system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The release system is divided into two separate components: a launch vehicle adaptor plate that remains on the launch vehicle, and a flyaway plate that attaches to the satellite. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining separation reliability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The release mechanism is extracted from the satellite itself and placed on the launch vehicle adaptor plate. This removes the complexity of the release system from the satellite, reducing satellite mass and complexity while the launch vehicle side handles the separation function.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a traditional release system is used, then satellite separation can be achieved, but the cost increases

Engineering Contradiction:
Improveseparation reliabilityVSAvoidmanufacturing cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The flyaway plate is designed as a disposable component that is discarded after separation. This allows the use of simpler, lower-cost materials and manufacturing methods for the flyaway plate, reducing overall system cost while maintaining reliable separation functionality.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The launch vehicle adaptor plate is designed with universal interfaces that can accommodate multiple different satellite types and mission requirements. This multi-functionality reduces the need for custom-designed release systems for each mission, lowering manufacturing costs through standardization.

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

3Reliability

If a traditional release system is used, then satellite separation can be achieved, but the satellite mass increases

Engineering Contradiction:
Improveseparation reliabilityVSAvoidsatellite mass
Core Design Contradiction:
ReliabilityVSWeight of moving object

Solution Approach 1:

The release mechanism is extracted from the satellite and placed on the launch vehicle adaptor plate. This removes the mass of the release system from the satellite, directly reducing satellite mass while the launch vehicle side absorbs the weight of the separation mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flyaway plate is designed as a lightweight disposable component with minimal mass. Since it is discarded after separation, its mass does not need to be recovered, allowing for optimized lightweight design that reduces satellite mass while maintaining separation reliability.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Reliability

If a traditional release system is used, then satellite separation can be achieved, but the satellite volume increases

Engineering Contradiction:
Improveseparation reliabilityVSAvoidsatellite volume
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The release system components are extracted from the satellite body and placed on the launch vehicle adaptor plate. This removes the volume occupied by release mechanism components from the satellite, reducing satellite volume while maintaining separation functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The flyaway plate is designed as a thin, lightweight disposable component with minimal volume. Its temporary nature allows for optimized compact design that reduces satellite volume while providing reliable separation when needed.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

5Reliability

If a traditional release system is used, then satellite separation can be achieved, but the system lacks flexibility for different launch vehicles

Engineering Contradiction:
Improveseparation reliabilityVSAvoidlaunch vehicle compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The launch vehicle adaptor plate is designed with universal interfaces and standardized mounting features that can accommodate multiple different launch vehicle types. This multi-functionality allows the same adaptor plate design to work across different launch vehicles, providing flexibility and adaptability while maintaining reliable separation.

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

Solution Approach 2:

The release system is segmented into modular components with standardized interfaces. This modularity allows different combinations of adaptor plates and flyaway plates to be configured for different launch vehicle and satellite combinations, enhancing system flexibility and adaptability.

Inventive Principle:
Principle #1Segmentation

AI summary

A release system may include a space vehicle separation plate operably coupled to a space vehicle, a launch vehicle adaptor plate operably coupled to a launch vehicle capable of carrying the space vehicle into space or into a ballistic (non-orbital) trajectory for release of the space vehicle from the launch vehicle, an actuator release mechanism assembly and a biasing element assembly. The actuator release mechanism assembly may be configured to separably couple the space vehicle separation plate to the launch vehicle adaptor plate. The biasing element assembly may be configured to provide a configurable force in a first direction normal to a surface of the launch vehicle adaptor plate to separate the space vehicle separation plate from the launch vehicle adaptor plate when the actuator-release mechanism assembly is triggered to release the space vehicle separation plate from the launch vehicle adaptor plate.
