Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If soft errors testing is performed at dedicated research facilities, then testing accuracy and reliability are improved, but testing time and cost increase significantly

Engineering Contradiction:
Improvetesting accuracyVSAvoidtesting time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The radiation source is extracted from the dedicated research facility and placed directly into the manufacturing environment, allowing testing to occur at the production site rather than requiring shipment to external labs, thereby eliminating shipping time and enabling immediate testing

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A portable radiation source acts as an intermediary that brings the testing capability to the manufacturing floor, serving as a mobile bridge between the need for accurate radiation testing and the desire to perform testing locally without full facility relocation

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If dedicated load boards are designed for each device, then testing compatibility is improved, but device complexity and cost increase

Engineering Contradiction:
Improvetesting compatibilityVSAvoidload board complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The load board is designed with universal compatibility features that allow it to interface with multiple different device types and packaging formats, eliminating the need to design custom load boards for each device while maintaining proper electrical and mechanical connections

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

Solution Approach 2:

The load board incorporates adjustable and reconfigurable connection interfaces that can adapt to different device configurations, allowing a single load board design to serve multiple device types through dynamic reconfiguration rather than static dedicated connections

Inventive Principle:
Principle #15Dynamics

3Reliability

If devices are shipped to external labs for testing, then testing professionalism is improved, but resource utilization deteriorates

Engineering Contradiction:
Improvetesting professionalismVSAvoidresource utilization
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The manufacturing facility performs soft errors testing independently using the portable radiation source and integrated testing apparatus, eliminating the need to outsource to external labs and thereby maintaining full control over the testing process while improving resource utilization

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The complex facility-based radiation testing system is replaced with a portable, self-contained radiation source that can be deployed directly at the manufacturing site, substituting the need for extensive mechanical infrastructure while maintaining testing capability

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