Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensor systems are attached to a machine tool for measurement, then measurement capability is improved, but data synchronization problems occur and traffic volume increases
Solution Approach 1:
The patent combines multiple sensor systems (power sensor, temperature sensor, humidity sensor, vibration sensor, illuminance sensor) into a single integrated sensor platform apparatus. This unified structure allows centralized data collection and processing, solving the data synchronization problem that arises when multiple separate sensor systems are attached to machine tools.
Solution Approach 2:
The sensor platform apparatus is designed with multi-functional capabilities to measure various physical quantities simultaneously (power, temperature, humidity, vibration, illuminance). This universal design improves measurement capability while maintaining data synchronization through a single integrated system that can handle diverse sensor types.
2Ease of operation
If wireless transmission is used for sensor data, then ease of operation is improved, but traffic volume increases
Solution Approach 1:
The micro-control unit executes predefined algorithms to perform preliminary data processing, filtering, and analysis before transmission. By pre-processing data locally, the system reduces the volume of data that needs to be transmitted wirelessly, thereby maintaining ease of operation while reducing traffic burden on communication networks.
Solution Approach 2:
The sensor platform apparatus performs self-service through edge computing capabilities, where the micro-control unit autonomously processes and analyzes sensor data using embedded algorithms. This self-processing reduces dependency on external communication infrastructure and minimizes the traffic volume that must be transmitted wirelessly.
3Device complexity
If computation is performed at the end of the system, then centralization is improved, but edge computing efficiency is reduced
Solution Approach 1:
The patent implements a segmented computing architecture where computation is divided between edge devices (sensor platform apparatus with micro-control unit) and centralized systems. The micro-control unit executes predefined algorithms locally for real-time processing, while more complex analysis can be performed centrally. This segmentation maintains system centralization benefits while enabling efficient edge computing for time-sensitive operations.
4Volume of moving object
If a compact design is used for the sensor platform, then ease of installation is improved, but sensor integration capability is reduced
Solution Approach 1:
The sensor platform apparatus employs a nested modular design where multiple sensor modules can be integrated within a compact structure. The device includes standardized terminals that can accommodate various sensor types, allowing the system to maintain a small form factor while preserving the ability to integrate multiple different sensor modules as needed.
