Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chip resistors are connected in series on the circuit board, then voltage division function is achieved, but ash and water vapor accumulate at connecting points forming parasitic resistors that affect stability
Solution Approach 1:
The patent extracts the harmful connecting points from the circuit board surface by suspending them in three-dimensional space using insulation columns. The connecting points are taken out from the plane where ash and water vapor accumulate, placing them in isolated air spaces above the circuit board, thereby eliminating the harmful accumulation environment.
Solution Approach 2:
The patent transitions from a two-dimensional circuit board layout to a three-dimensional structure by using insulation columns to elevate connecting points vertically. This dimensional change creates air gaps that prevent ash and water vapor from reaching the connecting points, solving the accumulation problem through spatial reconfiguration.
2Device complexity
If connecting points are placed close together on the circuit board, then device complexity is reduced, but point discharge phenomena occur under high voltage
Solution Approach 1:
The patent uses vertical insulation columns to separate connecting points in the third dimension while maintaining compact horizontal layout. This allows connecting points to be physically close on the board yet electrically isolated through the vertical air gap, preventing point discharge while preserving layout simplicity.
Solution Approach 2:
The insulation columns act as intermediary structures that provide both mechanical support and electrical isolation. These columns create safe discharge paths and prevent direct arcing between closely spaced connecting points under high voltage conditions.
3Measurement precision
If high voltage is applied to chip resistors, then voltage division function is achieved, but parasitic capacitors form with ash affecting voltage amplitude and phase
Solution Approach 1:
The patent extracts the connecting points from the circuit board surface into three-dimensional air spaces using insulation columns. This removal from the board surface prevents ash accumulation at connecting points, thereby eliminating the formation of parasitic capacitors that would otherwise form between ash layers and conductive elements.
