Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cord set with a receptacle and plug is used to connect electrically powered accessories to a power source, then electrical connection is established, but the connection process becomes complex and lacks visual confirmation
Solution Approach 1:
The patent combines multiple functions into a single integrated connector assembly: the receptacle, plug, and indicator light are merged into one unit. The indicator light is built into the receptacle housing, eliminating the need for separate indication devices and simplifying the overall system while providing reliable visual confirmation of electrical connection status
Solution Approach 2:
The connector assembly serves multiple functions simultaneously: it provides electrical connection (receptacle and plug), visual indication of power status (integrated indicator light), and structural mounting capability (flange with bolt holes). This multi-functionality reduces the number of separate components needed and simplifies the connection process
2Ease of operation
If a cord set with removable plug and receptacle is used, then ease of connection and disconnection is achieved, but visual indication of power presence is lacking
Solution Approach 1:
The integrated indicator light provides immediate visual feedback to the user about the power status. When the plug is properly connected and power is present, the indicator light illuminates, giving the user real-time information about the connection status without requiring separate indication devices or complex signaling systems
Solution Approach 2:
The indicator light is physically integrated into the receptacle housing, combining the connection interface and status indication functions in one component. This integration ensures that the visual information is always available at the connection point and eliminates the need for separate indication mechanisms
3Reliability
If a cylindrical connector with spring biased cover is used, then protection and sealing are provided, but the connector lacks integrated visual indication
Solution Approach 1:
The indicator light is integrated directly into the receptacle housing structure, merging the protection/shielding function with the visual indication function. The light is positioned within the housing and visible through an opening in the flange, eliminating the need for separate indication components while maintaining the protective cylindrical structure
Solution Approach 2:
The receptacle housing serves dual purposes: it provides structural protection and sealing for the electrical connection, and simultaneously houses the indicator light mechanism. This multi-functionality reduces overall system complexity while maintaining reliable protection and visual feedback
