Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical connector is used in a high-temperature and high-humidity environment, then the sampling assembly can operate in harsh conditions, but condensed water causes connection between terminals without electrical connection, affecting sampling performance
Solution Approach 1:
The electrical connector is divided into a first cavity and a second cavity by an insulating wall, with each cavity housing separate connection terminals. This segmentation prevents condensed water from creating conductive paths between terminals in different cavities, thereby maintaining electrical connection reliability while enabling operation in high-temperature and high-humidity environments.
Solution Approach 2:
An insulating wall acts as an intermediary barrier between the first and second cavities, physically separating the connection terminals. This intermediary structure blocks the formation of water droplets that could bridge terminals, thus preventing false electrical connections while allowing the connector to function in harsh environmental conditions.
2Quantity of substance
If connection terminals are arranged closely in the electrical connector, then the connector size is reduced, but condensed water can easily cause connection between terminals without electrical connection
Solution Approach 1:
By segmenting the connector into multiple cavities separated by insulating walls, the design allows terminals within each cavity to be arranged closely for compactness, while the insulating walls prevent water droplets from causing interference between terminals in different cavities. This resolves the contradiction between compact size and resistance to water droplet interference.
Solution Approach 2:
The insulating walls provide localized isolation between cavities, allowing the majority of the connector structure to remain compact while specifically addressing the water droplet interference issue at critical interfaces between terminal groups. This localized quality enhancement maintains overall compactness while preventing harmful effects.
