1Adaptability or versatility

If computational operations are performed using code from different APIs, then functionality and versatility are improved, but time consumption and resource usage increase

Engineering Contradiction:

ImproveAPI interoperabilityVSAvoidexecution time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent introduces semaphores as intermediary synchronization primitives that mediate between different APIs. The semaphore wait node acts as an intermediary mechanism that allows graph code from one API to synchronize with and wait for signals from code executed by another API, enabling efficient cross-API coordination without excessive resource consumption or time loss

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The semaphore mechanism provides a universal synchronization interface that works across multiple different APIs. By implementing a common semaphore wait node that can signal and wait on semaphores allocated by other APIs, the system achieves multi-functional interoperability while maintaining efficient resource utilization and execution time

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If computational operations are performed using code from different APIs, then functionality and versatility are improved, but power consumption increases

Engineering Contradiction:

ImproveAPI interoperabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

Semaphores serve as energy-efficient intermediary structures that enable cross-API communication without requiring continuous active monitoring or complex synchronization protocols. The semaphore wait node can efficiently wait for signals in a low-power state, reducing overall power consumption while maintaining API interoperability

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The semaphore mechanism enables self-service synchronization where each API can allocate and manage its own semaphores independently. The graph code can autonomously wait on semaphores allocated by other APIs without requiring complex inter-API coordination overhead, reducing power consumption through simplified synchronization

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If computational operations are performed using code from different APIs, then functionality and versatility are improved, but computing resource consumption increases

Engineering Contradiction:

ImproveAPI interoperabilityVSAvoidcomputing resources

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Semaphores act as lightweight intermediary structures that require minimal computing resources compared to complex inter-API communication mechanisms. The semaphore wait node provides efficient synchronization with low memory overhead and minimal processor intervention, enabling API interoperability while conserving computing resources

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The semaphore mechanism uses simple integer-based signaling (copying the semaphore value) rather than complex data structure exchanges between APIs. This lightweight copying approach enables efficient synchronization with minimal resource consumption while maintaining full API interoperability

Inventive Principle:

Principle #26Copying
