Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mechanical actuation or conventional control methods are used, then operation is possible, but operation convenience deteriorates and cost increases
Solution Approach 1:
The patent replaces mechanical actuation systems and conventional control panels with a magnetic field-based contactless control system. A hand-operated apparatus generates magnetic fields that are detected by magnetic field sensors, eliminating the need for mechanical keys, buttons, or complex control interfaces while improving ease of operation.
Solution Approach 2:
The patent introduces magnetic fields as an intermediary between the user and the valve drive device. The hand-operated apparatus modulates magnetic fields to encode control commands, which are then detected by magnetic field sensors, providing a simple yet effective communication channel without direct mechanical or electrical contact.
2Reliability
If line-bound data transfer techniques are used, then reliable data transfer is achieved, but cost increases
Solution Approach 1:
The patent replaces physical cabling and plug connections with contactless magnetic field communication. The hand-operated apparatus transmits control signals by modulating magnetic fields, which are detected by sensors in the valve drive device, eliminating the need for expensive line-bound data transfer infrastructure while maintaining reliability.
3Ease of operation
If wireless data transfer via modems is used, then operation flexibility is improved, but cost increases
Solution Approach 1:
The patent replaces complex wireless modem interfaces with a simple magnetic field-based communication system. The hand-operated apparatus directly modulates magnetic fields to transmit commands, which are detected by nearby sensors, providing wireless operation flexibility without the cost and complexity of conventional wireless data transfer technologies.
4Reliability
If mechanical actuation inside the valve drive device is used, then control actions can be triggered, but wear occurs and operation becomes awkward
Solution Approach 1:
The patent replaces internal mechanical actuation mechanisms with contactless magnetic field sensing. The hand-operated apparatus transmits control commands through magnetic fields that are detected by sensors inside the valve drive device, eliminating mechanical wear from keys and buttons while improving operation convenience by allowing control from outside the housing.
