Business Context
Interoperable systems allow spacecraft, ground networks, servicing vehicles, payloads, and infrastructure from different organizations to work together. Common interfaces can increase market access and reduce integration effort. However, proprietary architectures may achieve better performance by optimizing interfaces around specific hardware, software, or mission requirements.
Space TRIZ Resolution
Interoperability should be established at stable external boundaries while allowing internal architectures to remain optimized. Standardized data, mechanical, electrical, communications, or servicing interfaces do not require every internal implementation to be identical. Translation layers can also connect specialized systems where direct standardization would impose excessive performance penalties.
Applicable TRIZ Principles
Principle 1 – Segmentation separates standardized external interfaces from optimized internal architecture.
Principle 24 – Intermediary uses interface adapters or translation layers between different systems.
Principle 35 – Parameter Changes adapts interface parameters while maintaining common interaction rules.
Expected Outcome
Greater interoperability
Preserved internal performance
Lower integration barriers
Broader infrastructure compatibility
Decision Indicators
Early indicators include:
Integration requires extensive redesign between organizations.
Standardization forces unnecessary internal architecture changes.
Proprietary interfaces create long-term supplier dependency.
Technically compatible systems cannot exchange services or data.
Interface optimization and interoperability are treated as mutually exclusive.
