Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service device with wired or infrared connection is used to connect sanitary article controls to computers, then connection capability is achieved, but device complexity and ease of operation deteriorate due to requiring specialized service devices and separate connections for each control
Solution Approach 1:
The patent applies universality by enabling computers with standard wireless communication interfaces (Bluetooth, NFC) to connect to sanitary article controls without requiring specialized service devices. The wireless communication interface in the control unit allows any compatible computer to establish connections, eliminating the need for dedicated wired or infrared service devices and simplifying the overall system architecture.
Solution Approach 2:
The patent introduces an intermediary pairing process that mediates connections between computers and sanitary article controls. The pairing code displayed on the control unit's output interface acts as an intermediary verification mechanism, ensuring secure connections while simplifying the connection process for end users who don't need specialized service devices.
2Reliability
If a service device establishes separate connections with each sanitary article control, then individual control connection is achieved, but ease of operation and productivity deteriorate in large systems requiring maintenance of multiple controls
Solution Approach 1:
The patent applies feedback by displaying a pairing code on the output interface of the sanitary article control unit. This visual feedback allows maintenance personnel to verify which control is currently being connected to, ensuring connection accuracy while enabling efficient management of multiple controls in large systems through clear identification and confirmation.
Solution Approach 2:
The control unit performs self-identification by displaying its own pairing code on the output interface, allowing maintenance personnel to easily identify and connect to the correct control without requiring complex device management. The control unit essentially serves itself by providing its identification information directly to the user.
3Ease of operation
If wireless connection protocols like Bluetooth are used for connection, then ease of operation improves, but reliability deteriorates due to uncontrolled connection processes and risk of connecting to incorrect controls
Solution Approach 1:
The patent applies preliminary action by requiring the pairing process to be initiated first, during which a pairing code is displayed on the output interface. This preliminary verification step ensures that the correct control is identified and selected before the actual wireless connection is established, preventing unauthorized or incorrect connections while maintaining ease of operation.
