Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical connectors are used for data transmission, then data transmission is achieved, but the connectors are susceptible to interference and mechanical wear in difficult environmental conditions
Solution Approach 1:
The patent combines electrical contact transmission and inductive contactless transmission into a single connection arrangement. The electrical contacts provide power transmission while the inductive transmission device handles data transmission contactlessly, merging both principles to resolve the contradiction between reliable data transmission and resistance to environmental harm.
Solution Approach 2:
The patent replaces the mechanical contact-based data transmission with contactless inductive transmission. The inductive transmission device uses electromagnetic fields to transmit data without physical contact, eliminating mechanical wear and improving resistance to environmental factors while maintaining data transmission capability.
2Reliability
If inductive transmission systems are used for power transmission, then contactless transmission is achieved, but the system dimensioning becomes problematic and power transmission efficiency decreases
Solution Approach 1:
The patent segments the transmission functions by assigning power transmission to electrical contacts and data transmission to the inductive transmission device. This segmentation allows each subsystem to be optimized for its specific function, maintaining high power transmission efficiency through electrical contact while achieving contactless data transmission.
3Ease of operation
If mechanical connectors are used in difficult environmental conditions, then connection is achieved, but automatic coupling becomes difficult due to dirt and moisture
Solution Approach 1:
The patent introduces a tolerance compensation device as an intermediary mechanism that absorbs misalignments caused by dirt and moisture. This device includes compensation elements that can move relative to each other, allowing the connection to be established even when the connection parts are not perfectly aligned due to environmental contaminants.
4Power
If electrical contacts are used for power transmission, then high power transmission is achieved, but mechanical wear increases exponentially when dirty
Solution Approach 1:
The patent extracts the data transmission function from the electrical contacts and assigns it to the inductive transmission device. This extraction reduces the functional load on the electrical contacts, allowing them to focus on power transmission while minimizing their exposure to contaminants that cause wear, thereby extending their service life.
