Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shielding materials (epoxy resin with gadolinium oxide, cement mortar, concrete) are used to shield neutron radiation, then radiation shielding capability is improved, but material thickness and device volume must be increased
Solution Approach 1:
The patent changes the material composition parameter by replacing conventional shielding materials (gadolinium oxide, cement, concrete) with boride-containing materials. This parameter change enables superior neutron radiation shielding capability while reducing material thickness requirements, directly resolving the contradiction between shielding effectiveness and thickness.
Solution Approach 2:
The patent employs composite materials containing borides combined with other substances to create a shielding material that achieves high radiation blocking efficiency in reduced thickness. The composite structure leverages the unique properties of borides to outperform conventional homogeneous shielding materials.
2Object-affected harmful factors
If conventional shielding materials are used, then radiation protection is improved, but device miniaturization is hindered
Solution Approach 1:
By changing the material composition to boride-based materials, the patent achieves enhanced radiation protection with reduced thickness requirements. This enables semiconductor devices to maintain compact dimensions while obtaining superior radiation shielding, thus supporting device miniaturization rather than hindering it.
3Reliability
If conventional shielding materials are used, then neutron radiation shielding is improved, but material usage efficiency decreases
Solution Approach 1:
The patent changes the chemical composition parameter by adopting boride materials, which exhibit superior neutron capture efficiency per unit mass and volume compared to conventional materials like gadolinium oxide, cement, or concrete. This results in more efficient material usage for achieving the same or better shielding performance.
