Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If smart water meters are installed to achieve automatic water consumption reading and control, then water resource management efficiency is improved, but installation cost and certification complexity increase
Solution Approach 1:
The smart reading device is designed to be universally compatible with traditional water meters of different diameters through an adjustable clamping structure. It integrates multiple functions including image capture, optical character recognition, data transmission, and water leakage detection into a single device that can be installed on existing meters without replacement, thereby improving water resource management efficiency while avoiding the complexity of full smart meter replacement and certification
Solution Approach 2:
The device acts as an intermediary between traditional water meters and the smart water management system. It captures images of the meter display, converts them to digital data through OCR, and transmits this data wirelessly to remote servers, thereby enabling smart functionality on traditional meters without requiring direct integration or replacement of the original meter infrastructure
2Extent of automation
If traditional water meters are replaced with smart water meters to enable automatic reading, then reading automation is improved, but installation cost and pipeline construction requirements increase
Solution Approach 1:
Instead of replacing the physical water meter, the device creates a digital copy of the meter reading by capturing images of the display and converting them to digital data through optical character recognition. This approach achieves reading automation while avoiding the high costs of meter replacement and pipeline construction
Solution Approach 2:
The device replaces manual reading processes with automated image capture and optical character recognition technology. The mechanical interaction of manually reading the meter is substituted by an optical system that captures and processes images automatically, thereby achieving automation without the need for expensive smart meter replacement
3Measurement precision
If smart water meters with fixed diameters are used to ensure measurement accuracy, then measurement precision is improved, but adaptability to different pipe sizes deteriorates
Solution Approach 1:
The clamping structure of the reading device is designed to be adjustable and adaptable to different water meter diameters. This dynamic adjustment capability allows the device to maintain proper positioning and image capture quality across various meter sizes, thereby preserving measurement precision while achieving broad adaptability
