Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connection is used between hot water supply devices, then connection reliability is ensured, but setup time increases significantly as the number of devices increases
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. Each hot water supply device is equipped with a wireless communication module that enables automatic pairing through wireless signals, eliminating the need for physical cable connections and significantly reducing setup time while maintaining connection reliability through automated pairing protocols.
Solution Approach 2:
The patent implements self-service pairing functionality where hot water supply devices automatically identify and pair with each other without manual intervention. The devices use automatic device identification and pairing mechanisms to establish connections autonomously, eliminating the time-consuming process of manual wired connections while ensuring reliable system integration.
2Loss of time
If wireless connection is used between hot water supply devices, then setup time is reduced, but risk of incorrect pairing or device omission increases
Solution Approach 1:
The patent incorporates feedback mechanisms where wireless communication modules continuously monitor and exchange pairing status information between devices. The system provides real-time feedback on connection status, enabling automatic detection and correction of pairing errors, and ensuring that all devices are correctly integrated into the system without manual verification.
Solution Approach 2:
The patent implements preliminary device identification and verification protocols before final pairing is established. Devices exchange identification information and verify compatibility in advance, preventing incorrect pairing from occurring in the first place. This preliminary action ensures that only appropriate devices are paired together, maintaining high pairing accuracy.
3Adaptability or versatility
If all wireless communication modules remain active, then pairing flexibility is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic activation of wireless communication modules instead of continuous operation. Modules are activated only when pairing operations are required and deactivated during normal operation to conserve energy. This periodic action maintains pairing flexibility when needed while significantly reducing overall energy consumption of the system.
Solution Approach 2:
The patent employs dynamic power management where the operational state of wireless communication modules is adjusted based on system requirements. Modules transition between active and sleep states dynamically, remaining flexible for pairing when necessary but conserving energy during stable operation, thus balancing adaptability with energy efficiency.
