Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional packaging technology is used for electronic elements, then manufacturing processes are simpler, but integration efficiency and space utilization deteriorate
Solution Approach 1:
The patent merges the protective layer and circuit structure into a single integrated component. The protective layer serves dual functions: protecting the sensing element and providing structural support for the circuit pattern, thereby reducing the number of separate packaging components and improving integration efficiency
Solution Approach 2:
The protective layer is designed to perform multiple functions simultaneously: mechanical protection of the sensing element, electrical insulation, and structural substrate for circuit traces. This multi-functionality reduces the need for separate components and enhances packaging efficiency
2Adaptability or versatility
If multiple separate control units are used for different elements, then control functionality is more comprehensive, but device complexity and space requirements increase
Solution Approach 1:
The patent implements a shared control unit that manages multiple sensing elements through time-division multiplexing. The control unit alternates between reading different sensing elements, providing comprehensive control functionality while using a single control unit, thereby reducing device complexity and space requirements
Solution Approach 2:
The control unit operates in periodic cycles, sequentially selecting and reading different sensing elements. This time-division approach allows one control unit to handle multiple elements effectively, reducing the total number of control units needed while maintaining comprehensive control capability
3Area of stationary object
If circuit structure is placed outside the protective layer, then manufacturing is easier, but space utilization and integration density deteriorate
Solution Approach 1:
The patent transitions the circuit structure from a planar arrangement outside the protective layer to a three-dimensional integration where circuits are patterned on the surface of the protective layer itself. This dimensional reorganization maximizes space utilization by using the protective layer's surface area for circuit routing
Solution Approach 2:
The circuit pattern is nested within the protective layer structure, with circuit traces routed on the protective layer's surface. This nesting approach integrates the circuit structure within the existing protective layer geometry, optimizing space utilization without requiring separate external circuit boards
