Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If each sensor is connected to the signal processor via its own transmission wires, then the signal processor can distinguish individual pressure points, but the number of transmission wires increases, increasing costs and complexity
Solution Approach 1:
Multiple sensors (A, B, C) are connected in parallel to share common transmission wires. The sensors are combined into a single circuit group that uses only two transmission wires (first and second wires) to connect to the signal processor, eliminating the need for separate wires for each sensor while maintaining the ability to distinguish individual pressure points through unique circuit output values.
Solution Approach 2:
The first and second transmission wires serve multiple functions by being shared across all sensors. These two wires universally connect all sensors (A, B, C) to the signal processor, replacing the need for multiple dedicated wire pairs. Each wire carries signals from multiple sensors simultaneously, demonstrating multi-functionality.
2Reliability
If multiple transmission wires are used to connect sensors, then individual sensor signals can be transmitted, but the chance of wire breakage and malfunction increases
Solution Approach 1:
Multiple sensor connections are merged into a single parallel circuit using only two transmission wires. This consolidation reduces the total number of wire connections from multiple separate wires to just two shared wires, thereby reducing the probability of wire breakage and malfunction while maintaining reliable signal transmission from all sensors.
3Adaptability or versatility
If more wires are arranged on cloth material, then more sensors can be connected, but the arrangement becomes complicated and isolation between wires becomes difficult
Solution Approach 1:
Multiple sensor connections are merged into a single parallel circuit configuration that requires only two transmission wires. This merging simplifies the wiring arrangement on the cloth material, making it easier to manufacture and maintain proper isolation between wires, while still enabling connectivity to multiple sensors through the shared parallel circuit.
4Measurement precision
If each sensor has separate output terminals, then individual sensor identification is possible, but the number of connection points increases, increasing costs
Solution Approach 1:
Multiple sensor output terminals are merged into a shared parallel circuit configuration. Instead of requiring separate connection points for each sensor, the sensors share common first and second connection points on the transmission wires. The unique identification of each sensor is maintained through the distinct circuit output values produced by each sensor's unique configuration within the parallel circuit.
Solution Approach 2:
The first and second connection points on the transmission wires serve universal functions by connecting to multiple sensors simultaneously. These connection points are not dedicated to single sensors but universally interface with all sensors in the parallel circuit, reducing the total number of connection points required while maintaining sensor identification capability.

AI summary
A sensing device comprises a substrate material layer and a plurality of sensors provided on the substrate material layer. The plurality of sensors is electrically connected to form a loop. The loop has two output ends. There is a loop output value between the two output ends. The loop output value varies when the sensors are subjected to an external force. Each sensor has one induction value. The induction value of each sensor is different from each other. A total induction value of any one or more sensors is different from a total induction value of the other one or more sensors.
