Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple applications are installed on RTOS devices to enable separate application execution, then application versatility is improved, but performance stability deteriorates because performance varies substantially with each combination of applications

Engineering Contradiction:

Improveapplication execution capabilityVSAvoidperformance stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by simulating application combinations before deployment to a real RTOS device. The simulation component pre-evaluates multiple application combinations offline to identify stable configurations, avoiding the need to test each combination on the actual device. This resolves the contradiction by establishing performance stability through advance simulation while maintaining application versatility through multi-combination evaluation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses a simulation component that creates a virtual copy of the RTOS device environment. This copying approach allows performance testing of multiple application combinations in the simulated environment without affecting the actual device. The simulation model replicates device behavior to predict real-world performance, enabling versatile application testing while maintaining device stability.

Inventive Principle:

Principle #26Copying

2Adaptability or versatility

If new firmware is developed to change device functionality, then device adaptability is improved, but development complexity and testing requirements increase

Engineering Contradiction:

Improvedevice functionalityVSAvoidfirmware development complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a simulation component that copies the RTOS device environment, allowing firmware functionality changes to be tested in the simulated environment before deployment. This copying approach enables developers to modify device functionality through firmware updates while using the simulation model to verify correctness, reducing overall development complexity despite the need for comprehensive testing.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent applies preliminary action by performing firmware testing and validation in the simulation environment before deploying to actual devices. The simulation component pre-verifyes new firmware functionality and application compatibility, catching issues early in development. This reduces the complexity of field testing and deployment while maintaining high device adaptability.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If application combinations are tested on actual RTOS devices to ensure stability, then performance reliability is improved, but deployment time and resource consumption increase

Engineering Contradiction:

Improveapplication combination stabilityVSAvoiddeployment time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent uses a simulation component that creates a virtual copy of the RTOS device, allowing application combination testing to be performed in the simulated environment rather than on actual devices. This copying approach maintains performance reliability by accurately modeling device behavior while dramatically reducing deployment time, as simulations can run in parallel and do not require physical device availability.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent applies preliminary action by conducting all application combination testing and validation in the simulation environment before deployment. The simulation component pre-identifies stable application combinations and generates deployment recommendations, eliminating the need for time-consuming post-deployment testing on actual RTOS devices.

Inventive Principle:

Principle #10Preliminary action
