Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual design and manufacture are performed for each sensor device according to specific conditions, then the sensor device can be customized to match arrangement location shape and required number of sensor cells, but the design and manufacturing process becomes complicated and requires more time and effort, resulting in increased costs
Solution Approach 1:
The sensor array is divided into multiple independently detachable sensor cell groups (first sensor cell group and second sensor cell group) that can be separately manufactured and then combined. This segmentation allows standardization of manufacturing processes while enabling flexible configuration to match different arrangement locations and sensor cell requirements, thus reducing design complexity and costs.
Solution Approach 2:
The invention creates a universal sensor array structure with standardized terminal portions and conductor wire connections that can accommodate different numbers and configurations of sensor cells. The first and second sensor cell groups use the same connection interface and can be interchangeably connected to terminal portions, allowing the same manufacturing process to produce universally compatible sensor modules for various applications.
2Adaptability or versatility
If conductor wires are disconnected from sensor cells during separation into cell groups, then the sensor array can be reconfigured flexibly, but the disconnected conductor wires may generate noise and interfere with sensor operations
Solution Approach 1:
Disconnected conductor wires are connected to a reference potential (ground) through the reference potential-setting portion. This equipotential connection prevents voltage differences and electromagnetic radiation from the disconnected wires, eliminating noise interference while maintaining the flexibility to reconfigure sensor cell groups by cutting conductor wires at appropriate positions.
3Quantity of substance
If a large number of conductor wires are used to connect multiple sensor cells to terminal portions, then all sensor cells can be connected, but the complexity of connection management and potential for errors increases
Solution Approach 1:
The sensor array is segmented into multiple sensor cell groups (first sensor cell group, second sensor cell group, etc.) that can be independently connected to terminal portions. Each group contains a manageable number of sensor cells with their own conductor wires, reducing the complexity of connection management compared to connecting all sensor cells individually to terminal portions.
Solution Approach 2:
Multiple sensor cell groups use standardized connection interfaces and conductor wire configurations that can be universally connected to terminal portions. This universality simplifies connection management by providing repeatable, error-resistant connection patterns regardless of the total number of sensor cells being connected.

AI summary
An electric circuit body includes: a plurality of sensor cells integrally aligned; one or more terminal portions (a first terminal portion and a second terminal portion); and a conductor wire (a first conductor wire and a second conductor wire). Each terminal portion includes a plurality of terminals connected to the plurality of sensor cells. The conductor wire connects the plurality of terminals and the plurality of sensor cells. The plurality of sensor cells are separated into a first cell group connected to a predetermined terminal portion (for example, a first terminal portion) and a second cell group disconnected from the predetermined terminal portion by cutting the plurality of conductor wires at an appropriate position.
