Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication connectors are used in special environments, then communication connection between devices is established, but wiring difficulties increase and maintenance costs increase
Solution Approach 1:
The patent replaces the mechanical wired connector system with an electromagnetic field-based contactless transmission system. The transmitting device generates electromagnetic signals that are received by the receiving device without physical contact, eliminating the need for mechanical plugging and unplugging of connectors in special environments.
Solution Approach 2:
The patent introduces electromagnetic fields as an intermediary medium to transfer communication signals between devices. Instead of direct physical connection through connectors, the electromagnetic field serves as the mediator that carries information across the interface, enabling contactless communication.
2Adaptability or versatility
If connectors are plugged and unplugged frequently for communication, then communication flexibility is improved, but service life decreases and error rate increases
Solution Approach 1:
The patent eliminates the mechanical plugging and unplugging mechanism by using contactless electromagnetic transmission. The transmitting and receiving devices can establish and terminate communication by controlling the emission and detection of electromagnetic signals, without any physical contact or mechanical movement.
Solution Approach 2:
The patent enables dynamic control of communication establishment and termination through electromagnetic signal modulation. The transmitting device can dynamically start or stop signal emission, and the receiving device can dynamically adjust signal detection, providing communication flexibility without mechanical movement.
3Ease of operation
If wireless communication modules such as RF or infrared are used, then contactless communication is achieved, but transmission distance is limited and signal transmission is unstable in special environments
Solution Approach 1:
The patent changes the parameters of electromagnetic transmission by using magnetic field coupling between transmitting and receiving coils. This approach differs from RF or infrared by utilizing magnetic induction principles, which provide better stability in special environments through controlled magnetic field interaction and reduced environmental interference.
