Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a sensing device is connected to a network to construct a system for quantitative management of compression air, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent combines the flow rate measurement unit, real-time clock, calculation unit, storage unit, and screen generation unit into a single integrated gas flow meter device. This merging eliminates the need for separate sensing devices and network infrastructure, achieving quantitative measurement while reducing system complexity.
Solution Approach 2:
The gas flow meter performs multiple functions within a single device: it measures flow rate, tracks time, calculates integrated flow amounts, stores data, and generates graphical displays. This multi-functionality replaces what would otherwise require multiple separate devices and systems.
2Loss of information
If instantaneous flow rate is displayed continuously, then information availability is improved, but ease of operation deteriorates due to difficulty in grasping usage patterns
Solution Approach 1:
The patent transforms one-dimensional instantaneous flow rate data into a two-dimensional graphical display by plotting integrated flow amount against time. This dimensional transformation allows users to visually grasp usage patterns and trends that would be difficult to perceive from continuous numerical data alone.
Solution Approach 2:
The calculation unit continuously calculates integrated flow amounts in advance, and the storage unit stores these pre-processed data points. When display is needed, the graphical representation is generated immediately from pre-computed data, eliminating the need for real-time processing during display operations.
3Productivity
If historical flow data is stored and displayed, then productivity is improved through better energy management, but device complexity increases
Solution Approach 1:
The patent integrates the real-time clock, calculation unit, and storage unit within the flow meter device itself. This merging enables historical data storage and retrieval capabilities without requiring external systems, improving energy management productivity while keeping the device self-contained.
Solution Approach 2:
The gas flow meter performs its own data processing, storage, and graphical display generation without requiring external computers or network systems. The device serves itself by internally calculating integrated flow amounts, storing historical data, and generating visual representations for immediate viewing.

AI summary
In a temporally continued plurality of day-and-time sections, history data included in the past day-and-time section is graphically displayed on the basis of the integrated flow amount data stored in the storage unit, as an integrated flow amount in each day-and-time section. In the day-and-time section including the current day-and-time, the integrated flow amount in the day-and-time section based on the current integrated flow amount data is successively updated and graphically displayed.
