Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic components are densely arranged to improve integration, then device functionality increases, but electromagnetic interference between components worsens
Solution Approach 1:
A columnar conductor is introduced as an intermediary element positioned between adjacent electronic components. This conductor acts as a shield that intercepts and redirects electromagnetic fields, preventing direct interference between components while allowing the components to maintain their functional integrity and dense arrangement.
Solution Approach 2:
The columnar conductor provides localized electromagnetic shielding precisely where interference occurs between adjacent components. Rather than requiring comprehensive shielding of the entire device, the shield is strategically placed only in the critical interference zones, maintaining functionality while reducing interference locally.
2Reliability
If shielding structures are added to suppress electromagnetic interference, then operational reliability improves, but device complexity increases
Solution Approach 1:
The shielding function is segmented into discrete columnar conductors positioned between specific components rather than using a continuous shielding structure. This segmentation reduces the overall amount of shielding material and simplifies the device architecture while still providing effective interference suppression at critical locations.
Solution Approach 2:
The columnar conductor acts as a thin, minimal-structure shield that provides effective electromagnetic interference suppression without adding significant bulk or complexity to the device. The simple columnar geometry is easier to manufacture and integrate than complex continuous shielding structures.
