Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If redundant methods are used to mitigate soft errors, then reliability is improved, but cost and power consumption increase
Solution Approach 1:
The invention changes the parameter approach from binary redundancy (on/off) to continuous optimization by calculating specific soft error rates for different facility arrangements. This allows finding the optimal balance between reliability and power consumption by selecting arrangements that achieve adequate protection without excessive redundancy
Solution Approach 2:
The invention performs preliminary calculation of soft error rates during the facility arrangement design phase, before actual deployment. This allows optimizing the arrangement to achieve necessary reliability levels without over-engineering, thereby reducing unnecessary power consumption from redundant systems
2Reliability
If redundant methods are used to mitigate soft errors, then reliability is improved, but cost increases
Solution Approach 1:
The invention transforms the approach from fixed redundancy configurations to dynamic optimization based on calculated soft error rates. By evaluating specific error rates for different arrangements, the system identifies cost-effective solutions that achieve required reliability without excessive redundant infrastructure
Solution Approach 2:
The invention performs preliminary soft error rate calculations during the planning stage, enabling cost optimization before deployment. This allows selecting facility arrangements that meet reliability requirements at minimal cost, avoiding unnecessary expenditure on redundant systems
3Device complexity
If simple aggregation of soft error rates is used, then calculation simplicity is improved, but measurement precision deteriorates
Solution Approach 1:
The invention applies local quality by calculating soft error rates specifically for each facility's actual position and environment rather than using a uniform aggregation approach. This considers local factors such as building structure, facility location, and radiation exposure variations, providing more accurate results tailored to each specific context

AI summary
For a soft error of an electronic device, a technique capable of ensuring high reliability because of a low soft error rate (SER) is provided. By using building data including information of a structural object of a building and facility data including information of a plurality of facilities including an electronic device arranged in the building, a SER calculating device calculates a model including an attenuation index value representing a degree of attenuation of radiation entering the building attenuated by the structural object of the building until the radiation reaches a position of the facility arranged in the building, calculates a SER at each position of the facility arranged in the building by using the model including the attenuation index value, and outputs information including the SER at each position of the facility.
