Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If physical connection and power-up of cameras or hardware devices are used for testing image interfaces, then the verification process can confirm actual device functionality, but the verification efficiency is reduced and the process time is prolonged

Engineering Contradiction:
Improveverification reliabilityVSAvoidverification efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent uses a virtual camera to generate simulated image data that copies the functionality of a real camera without requiring physical hardware. The virtual camera creates test images through software, allowing the image interface to be tested with simulated data streams instead of actual camera devices, thus improving efficiency while maintaining verification capability

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces a virtual camera as an intermediary between the test system and the image interface. This virtual camera acts as a mediator that generates simulated image data to replace the need for physical camera connections, enabling indirect testing that is both efficient and reliable

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If physical cameras or hardware devices are connected for image interface verification, then comprehensive hardware functionality can be tested, but the complexity of the testing setup increases

Engineering Contradiction:
Improvehardware functionality verificationVSAvoidtesting setup complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the image data generation function from physical camera hardware and relocates it to a virtual camera software component. This separation allows the essential image data generation capability to be obtained without the complexity of physical camera connections, power management, and hardware configuration

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical/physical camera system with a software-based virtual camera system. Instead of using actual optical devices, lenses, and sensors that require physical connection and power, the system uses software algorithms to generate synthetic image data, substituting a complex physical system with a simpler computational one

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
