Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a code reader is used to input characteristic data to control circuitry, then data input accuracy is ensured, but ease of operation deteriorates due to limited accessibility and convenience
Solution Approach 1:
The mobile terminal is designed to perform multiple functions: capturing code images via camera, storing characteristic data in memory, processing the data through the processor, and transmitting to control circuitry via wireless communicator. This multi-functional device replaces the specialized code reader while maintaining data input capability and adding convenience through ubiquitous mobile device access.
Solution Approach 2:
The patent replaces the mechanical/optical code reader system with an electronic/mobile-based system. Instead of using a dedicated code reading device, the system uses a mobile terminal's camera to capture code images, processes them electronically, and transmits data wirelessly. This substitution eliminates the need for specialized hardware while maintaining functional equivalence.
2Device complexity
If a dedicated code reader is used for data input, then measurement precision is maintained, but device complexity increases due to requiring specialized equipment
Solution Approach 1:
The mobile terminal integrates multiple functions (camera for code capture, memory for data storage, processor for data processing, wireless communicator for transmission) into a single ubiquitous device. This eliminates the need for separate specialized equipment while maintaining the precision required for characteristic data input through the integrated system's coordinated operations.
3Loss of information
If characteristic data is stored locally on the pump equipment, then data accessibility is improved, but loss of information increases due to potential data loss during transfer
Solution Approach 1:
The patent replaces physical/data transfer-based data transmission with wireless electronic transmission. The mobile terminal captures the code image, processes the characteristic data electronically, and transmits it wirelessly to the control circuitry. This electronic-wireless pathway eliminates potential data loss associated with physical media transfer while maintaining data accessibility through the mobile device's processing capabilities.
Data Source
AI summary
A processor of a mobile terminal according to one embodiment, when a camera has captured an image of a code that is displayed on a surface of hydraulic pump equipment and that stores characteristic data of at least one pump included in the hydraulic pump equipment, stores the characteristic data in a memory. Further, the processor displays a virtual characteristic data transmission button on a touchscreen, and when the characteristic data transmission button is tap-operated, causes a wireless communicator to transmit the characteristic data stored in the memory to control circuitry for the hydraulic pump equipment or to a wireless LAN router connected to the control circuitry.
