Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors are integrated into the belt body, then measurement capability is provided, but sensor placement precision and measurement reproducibility deteriorate
Solution Approach 1:
The sensor system is divided into a fixed first sensor integrated into the belt body and a removable second sensor module that can be attached and detached. This segmentation allows the first sensor to provide stable, reproducible measurements while the second sensor module can be easily maintained and replaced, resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The second sensor is designed with removable attachment capability, allowing it to be dynamically attached or detached from the belt body. This dynamic design enables easy maintenance and replacement of the second sensor without affecting the first sensor, thereby maintaining measurement reproducibility while reducing integration complexity.
2Ease of repair
If sensors are made removable, then ease of maintenance is improved, but measurement precision and placement consistency deteriorate
Solution Approach 1:
The sensor system is segmented into a permanently fixed first sensor and a removable second sensor module. The first sensor remains fixed to ensure consistent placement and reproducible measurements, while the second sensor module can be easily removed for maintenance, thus resolving the contradiction between maintenance ease and measurement precision.
Solution Approach 2:
A removable attachment mechanism serves as an intermediary between the belt body and the second sensor. This intermediary allows the second sensor to be easily attached and detached for maintenance while maintaining stable positioning during use, thereby preserving measurement precision while improving maintenance ease.
3Adaptability or versatility
If multiple sensors are integrated into the belt, then monitoring capability is enhanced, but device complexity and difficulty of maintenance increase
Solution Approach 1:
Multiple sensors are segmented into two functional groups: a fixed first sensor for continuous monitoring and a removable second sensor module for supplementary measurements. This segmentation enhances monitoring capability while keeping the system manageable by allowing the second sensor to be easily replaced or upgraded without affecting the first sensor.
Solution Approach 2:
The removable second sensor module is designed to be universally attachable and contain multiple types of sensors (pressure, temperature, humidity). This multi-functionality enhances the overall monitoring capability of the belt while maintaining simplicity through modular design, resolving the contradiction between versatility and complexity.
