PDU Socket Structure With Protecting Seat for Stable Adapter Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current PDU power distribution apparatuses face safety issues due to loose socket connections, which allow items like steel rulers and coins to fall into the sockets and result in unstable power adapter insertion, leading to potential safety hazards and inconvenience in uniform distribution and numbering management.
Innovation Solution
The PDU power distribution apparatus incorporates a housing with a conductor assembly, a fixing element, a protecting seat, and a pre-installed seat that stabilizes the power adapter insertion, blocking the through hole when not in use and ensuring the conductor assembly is only exposed at the socket position, reducing the risk of foreign objects entering and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the socket is made larger to facilitate power adapter insertion, then the ease of operation is improved, but the safety deteriorates due to increased risk of foreign objects falling into the socket
Solution Approach 1:
The socket area is segmented into two functional zones: a through hole for power adapter insertion and a socket for electrical connection. This segmentation allows the through hole to be sufficiently large for easy insertion while the socket remains a controlled, smaller aperture that prevents foreign object entry.
Solution Approach 2:
The protecting seat acts as an intermediary structure between the through hole and the conductor assembly. It provides a protective barrier that prevents foreign objects from reaching the conductor assembly while still allowing power adapters to pass through the through hole and connect to the socket.
2Adaptability or versatility
If the power adapter insertion position is not fixed, then the adaptability is improved, but the reliability deteriorates due to unstable connection and potential tipping
Solution Approach 1:
The pre-installed seat is prepared in advance within the protecting seat, with the socket positioned at a specific location. This preliminary positioning ensures that when the power adapter is inserted, it automatically aligns with the correct insertion position, providing both adaptability and stable connection.
Solution Approach 2:
The pre-installed seat serves as an intermediary structure that guides and positions the power adapter during insertion. It ensures the power adapter connects reliably to the socket while maintaining the ability to accommodate different adapter types.
3Ease of operation
If the conductor assembly is fully exposed for easy access, then the ease of operation is improved, but the safety deteriorates due to increased exposure to foreign objects
Solution Approach 1:
The conductor assembly access path is segmented into two stages: first through the through hole in the protecting seat, and then into the socket in the pre-installed seat. This segmentation allows controlled access where the through hole provides initial access while the protecting seat filters out foreign objects.
Solution Approach 2:
The protecting seat acts as an intermediary protective barrier between the external environment and the conductor assembly. It allows power adapters to access the conductor assembly through the through hole while blocking foreign objects, thus maintaining both accessibility and safety.
